Description

  The present invention relates to a three-dimensional warp knitted fabric and a fiber product using the three-dimensional warp knitted fabric, and more specifically, while maintaining excellent cushioning properties, thickness retention, and shape stability of the three-dimensional warp knitted fabric, The present invention relates to a three-dimensional warp knitted fabric with improved air permeability and texture, and a fiber product using the three-dimensional warp knitted fabric.

Conventionally, urethane foam and non-woven fabric materials are used as materials for brassiere cup materials and the like.
Although the urethane foam is excellent in washing durability and compression recovery durability, there is a problem that stuffiness due to perspiration at the time of wearing tends to occur due to poor breathability. Furthermore, there is a problem that the light resistance is poor and yellowing is easily deteriorated by ultraviolet rays.
On the other hand, the nonwoven fabric material is excellent in air permeability, but has a problem that it is inferior in compression recovery durability and easily loses its shape.

  In recent years, a three-dimensional warp knitted fabric composed of two ground structures and connecting yarns connecting the two ground structures has come to be used in various fields due to its excellent resilience, cushioning properties, etc. Is widely used for general clothing, sports clothing, inner clothing, etc., and in the material field, it is widely used for interior skin materials. In particular, the three-dimensional structure warp knitted fabric excellent in form stability and washing durability has been attracting attention as a material such as a brassiere cup material.

  Conventionally, in the three-dimensional structure knitted fabric 1, as shown in the schematic cross-sectional view along the course direction shown in FIG. 9, one connecting thread 4 is provided in all the loops of the first ground structure 2 and the second ground structure 3. It is consolidated. That is, the ground structure is knitted with the same number of knitting yarns as the number of knitting needles, and the corresponding connecting yarns are connected and knitted to all the loops of the first ground structure 2 and the second ground structure 3. The thickness retention property and cushioning property of the three-dimensional structure warp knitted fabric 1 are improved by changing the angle with respect to the ground structures 2 and 3 (FIG. 10) and changing the fineness of the connecting yarn 4.

  On the other hand, the three-dimensional structure warp knitted fabric has a relatively hard texture, and a monofilament yarn may be used as a connecting yarn in order to improve cushioning properties. However, in this case, when pressure is applied to the knitted fabric, the monofilament yarn may jump out from the gaps or the sewing portion of the ground structure, and when used as an underwear material, the skin may be stimulated and uncomfortable. Moreover, in the said three-dimensional structure warp knitted fabric, air circulation is not fully performed in the part which is in contact with skin, and cancellation | disappearance of steam may be inadequate.

Therefore, Japanese Patent Laid-Open No. 2000-160459 (Patent Document 1) proposes a three-dimensional warp knitted fabric using multifilament yarns as connecting yarns in order to eliminate the irritation to the skin as described above.
However, in the multifilament yarn, the yarn is soft, and the cushioning property and thickness retention of the three-dimensional warp knitted fabric are liable to decrease. Therefore, in order to maintain cushioning and thickness retention, the fineness of the connecting yarn is increased. A method of increasing the hardness of the connecting yarn by increasing the number of connecting yarns is used. However, in this method, the fabric weight of the three-dimensional structure warp knitted fabric becomes heavy, and by connecting many connecting yarns between the ground structures, the gap between the connecting yarns is reduced and the air permeability is deteriorated. There is a problem that tends to become hard.

Moreover, in Unexamined-Japanese-Patent No. 11-200106 (patent document 2), among two knitted fabrics of the front and back of a three-dimensional structure warp knitted fabric, a cellulosic long fiber was used as a thread on at least the skin side to suppress the feeling of stuffiness. Bra cup materials have been proposed.
However, even if it has the said structure, when there is much sweating amount at the time of wear, there is also a problem that a feeling of suffice cannot be suppressed and the texture changes when the number of washings is increased.

JP 2000-160459 A JP-A-11-200106

The present invention has been made in view of the above problems, and while maintaining excellent cushioning and thickness retention of the three-dimensional structure warp knitted fabric, and form stability, it improves air permeability and suppresses the feeling of stuffiness, The object is to provide a three-dimensional warp knitted fabric with improved texture.
Moreover, the textile product which uses the said three-dimensional structure warp knitted fabric is provided, and it makes it the subject to raise a feeling of wear when it uses for the part which contacts skin, such as a cup part of a brassiere.

In order to solve the above problems, as a first aspect of the present invention, in the cross section in the course direction of a three-dimensional structure warp knitted fabric, the present invention obliquely intersects two ground texture planes that are flat structures having no openings on the surface . A three-dimensional structure warp knitted fabric including a structure in which a connecting yarn connects the two ground structures,
Among the two ground structures, one of the first ground structures is provided with loops that are not connected to the connecting yarn at a required interval,
The other second ground structure provides a three-dimensional warp knitted fabric characterized in that all loops are connected and knitted with one connecting yarn.

  As described above, since one connecting thread is connected to all the loops in the second ground structure, the number of connecting threads and the number of connecting threads are the same as the conventional structure, but the first ground structure is connected to the connecting thread. Since the loop which is not provided is provided, two or more connecting yarns are connected to the loop connected to the connecting yarns of the first ground texture. That is, the connecting yarns are knitted obliquely from the second ground structure toward the first ground structure at different angles in the course direction. For example, when it is set as the structure which alternately provides the loop connected with the 1st ground organization with the connecting yarn, and the loop which is not connected with the connecting yarn, two connecting yarns knitted and connected with the 2 loops in the 2nd ground organization are used. The first ground structure is connected and knitted with one loop, and the connected yarn is connected and knitted in a substantially triangular shape between the first and second ground structures. The connected yarns knitted in a substantially triangular shape are provided in parallel between the first and second ground structures in the course direction, and an inverted triangular gap is generated at a loop position not connected to the connected yarns of the first ground texture. .

  Thus, in the present invention, since the loop that is not connected to the connecting yarn is provided in the first ground texture, the air permeability on the first ground texture side can be improved from the second ground texture side, and Compared with the conventional structure in which all the loops of the first and second ground structures are connected and knitted with the connecting yarn, the gap between the connecting yarns is increased, and the air permeability between the connecting yarns can be improved. Therefore, the air permeability of the entire three-dimensional structure warp knitted fabric can be improved, moisture due to sweating can be quickly dried, and the feeling of stuffiness and stickiness can be reduced.

  Further, when the connecting yarn is formed in the substantially triangular shape as described above, and the connecting yarn knitted to the substantially triangular shape is formed in the adjacent loop of the first ground structure, it becomes a substantially trapezoidal shape. It is difficult to cause a shift in the course direction of the ground structure, and excellent shape stability, thickness retention, and cushioning properties can be maintained. Therefore, in addition to materials for cups such as brassiere, sports clothing materials, shoes materials, chair upholstery materials, etc., the material has more breathability and cushioning properties.

Further, in the first ground structure, a loop in which the connecting yarn is not connected and knitted is smaller than a loop in which the connecting yarn is connected and knitted, so that a large and small loop is generated in the first ground structure and the first ground structure is not connected by the connecting yarn. Can be improved from the second ground structure side.
Furthermore, the texture of the first ground structure with a small number of loops in which the connecting yarns are knitted is softer than the other second ground texture.
Therefore, in the textile product using the three-dimensional warp knitted fabric of the present invention, when the first ground structure is used as the skin side, it is possible to prevent the stuffiness and enhance the feeling of wearing, and also to improve the feeling of wearing.

  The first and second ground structures connected by the connecting yarn are knitted with all needles in the well direction and the loop is provided, and the course direction is 100% of the knitting ratio between the connecting thread and the second ground structure loop. Then, it is preferable that the knitting ratio of the connecting yarn and the loop of the first ground structure is 30 to 75%. The swing width of the connecting yarn in the first ground structure is preferably 1 to 6 needles, and the first ground structure is preferably connected by a connecting thread with 1 to 6 loops in the course direction.

  That is, it is preferable that the connection density of the connecting yarns in the first ground structure is 30 to 75%. The connection density of the connection yarn is preferably 30 to 75%. If the connection density is less than 30%, the form stability and cushioning properties may not be sufficiently obtained, while the connection density is 75%. If it exceeds, the density of the connecting yarn becomes high, and there is a possibility that a sufficient gap between the connecting yarns is not formed and the air permeability is impaired.

And it is preferable that the connection thread | yarn width of the said connection thread | yarn in a 1st ground structure shall be 1-6 needles, and 1-6 loops are opened in the course direction in this 1st ground structure, and it connects with a connection thread | yarn.
The swing width refers to the number of moving target knitting needles or the number of moving target wells when the warp of the warp knitting machine moves in one direction along the warp knitting needle row. As shown in FIG. 2, it means that the first ground organization is connected and knitted straight (not diagonally) from the second ground organization.
The reason why the swing width of the connecting yarn is preferably 1 to 6 stitches is that when the swing span is larger than 6 stitches, it becomes difficult to knit and the fabric weight is likely to be large.

  As the above-mentioned swing width, in the first ground structure, it is preferable that the interval between the loop to which the connecting yarn is connected and knitted is 1 to 6 loops. Breathability can be improved by widening the loop interval, but if the interval is larger than 6 loops, it becomes difficult to knit, and form stability and cushioning properties are hardly obtained.

  Examples of the fibers constituting the three-dimensional warp knitted fabric used in the present invention include polyester-based fibers such as polyethylene terephthalate, polyamide-based fibers such as nylon, cellulose-based recycled fibers, polyacrylonitrile-based fibers, cotton, silk, and wool. Natural fibers and mixed fiber thereof may be mentioned, but it is preferable to use a polyester fiber as the main component in terms of heat compression moldability, compression resilience, washing resistance, flexibility, and the like.

Moreover, when using the said three-dimensional structure warp knitted fabric as a raw material which forms the cup part of an inner material, as a connection yarn, the multifilament yarn whose fineness comprised by the yarn of 3-6 dtex of single yarn is 33-110 dtex is used. It is preferable to use it.
It is preferable that the single yarn fineness is 3 to 6 dtex. If the single yarn fineness is less than 3 dtex, the strength and elastic force of the fiber are weak, so that the morphological stability is lowered and a knitted fabric with no stiffness is easily obtained. When the single yarn fineness is larger than 6 dtex, the connecting yarn becomes hard, which may cause the connecting yarn to jump out on the surface of the three-dimensional warp knitted fabric, which may deteriorate the feeling of wearing, or the fabric may harden and the texture may deteriorate. by.
The fineness of the multifilament yarn is preferably 33 to 110 dtex. When the fineness is less than 33 dtex, the elastic stability of the fiber is weak and the shape stability is likely to decrease. On the other hand, when the fineness is greater than 110 dtex, the fabric This is because there is a possibility that the texture becomes harder and the texture becomes worse.

When multifilament yarns as described above are used, even under high pressure at the time of molding, the connecting yarns connect the front and back ground structures at different angles, so the pressure is dispersed and the connecting yarns are less likely to break. Excellent in properties. In addition, since the multifilament yarn is hard to be cured even when heated compared to a monofilament yarn having the same fineness, the flexibility of the fabric is not easily lost, and sufficient thickness retention, form stability, and compression resilience are ensured. be able to.
On the other hand, when a monofilament yarn is used as the connecting yarn, the fabric is cured by high temperature and high pressure at the time of molding, the flexibility is impaired, the form stability and compression resilience of the fabric are deteriorated, or the connecting yarn jumps out to the ground texture surface. There is a risk that the feeling of wear will deteriorate.

The three-dimensional warp knitted fabric used in the present invention can be knitted using a double raschel knitting machine having two opposite rows of needle beds, a warp knitting machine having a V bed, etc., but has good dimensional stability. In order to obtain a three-dimensional structure warp knitted fabric, the double raschel knitting machine is preferably used. The gauge of the knitting machine is preferably 9 to 28 gauge.
Moreover, by using the first and second ground structures as flat structures having no openings on the surface, when used for an inner material or a sports material, it is possible to prevent the connecting yarn from jumping out from the openings. A feeling of wearing can be obtained and see-through can be prevented. Moreover, when it uses for skin materials, such as a chair, a favorable seating feeling and texture can be obtained .

Furthermore, it is preferable that the three-dimensional warp knitted fabric used in the present invention has an air permeability measured value of 0.02 KPa · s / m or less by a KES-F8 air permeability tester.
The measured air permeability of the three-dimensional warp knitted fabric is preferably 0.02 KPa · s / m or less. When the measured air permeability exceeds 0.02 KPa · s / m, the three-dimensional warped knitted fabric is When used for breast clothing, it may cause a feeling of stuffiness.

Moreover, in the said three-dimensional structure warp knitted fabric, it is preferable that the fabric hardness of any one of a well direction or a course direction is 80-120 mm. It is preferable that the fabric hardness is 80 to 120 mm. If the fabric hardness exceeds 120 mm, the texture of the fabric may be hard. On the other hand, if the fabric hardness is less than 80 mm, the flexibility is too large and the shape stability is improved. This is because there is a risk of chipping. In particular, when used as a brassiere cup material, the breast shape and the like may not be properly corrected.
The fabric hardness in the present invention is measured by the JIS L 1018 cantilever method.

The three-dimensional structure warp knitted fabric preferably has a fabric thickness of 2 to 12 mm, particularly preferably 2.5 to 8 mm.
It is preferable that the thickness of the fabric is 2 to 12 mm. If the thickness is less than 2 mm, the form stability and the compression resilience may be impaired. On the other hand, if the thickness exceeds 12 mm, the fabric becomes heavier or feels. It is because there is a possibility that it may worsen.

As the three-dimensional structure warp knitted fabric of the mass (basis weight) is preferably 250~370g / ^{m 2,} it is preferred that particularly 280~350g / ^{m 2.}
The reason why it is preferable to have the mass of the three-dimensional structure warp knitted fabric and 250~370g / ^{m 2,} while there is a possibility that mass repulsive force and form stability is impaired is less than 250 g / ^{m 2,} mass 370 g / possibility that flexibility is impaired exceeds m ² due to the fact that there is.

Furthermore, the present invention provides, as a second invention, a textile product characterized by using the above three-dimensional warp knitted fabric.
As described above, the textile product using the above-described three-dimensional warp knitted fabric can retain excellent shape stability, thickness retention, cushioning properties, and excellent breathability. In addition to these materials and sports clothing materials, it is suitably used for textile products such as shoe materials and chair upholstery materials. In particular, it is preferable that the garment has a cup portion such as a brassiere.
Moreover, it is preferable that the 1st ground structure of the said three-dimensional structure warp knitted fabric is located in the skin side for the reason mentioned above.

Especially, the said textiles can be used suitably as clothing which has a cup part which used the said three-dimensional structure warp knitted fabric for the cup part.
Preferably, the cup part is heated and pressed to form a bulge part.
In this way, even after the three-dimensional structure warp knitted fabric is heated and pressed to form the bulging portion of the cup portion, the cup portion retains excellent cushioning properties, thickness retention properties, and form stability, as well as breathability and The texture can also be kept in a good state. Therefore, when wearing clothing having the cup part, while maintaining an appropriate correction force of the breast shape, to obtain an excellent wearing feeling without the feeling of stuffiness or stickiness due to sweating, unpleasant irritation to the skin, etc. Can do.

As molding conditions when the three-dimensional warp knitted fabric is hot-pressed to form the bulged portion of the cup portion, for example, the molding temperature is preferably 200 to 240 ° C. and the molding time is preferably 30 to 60 seconds. In particular, a molding temperature of 230 ° C. and a molding time of 45 seconds are preferable.
Further, the thickness of the cup part after molding is preferably about half of the thickness of the three-dimensional structure warp knitted fabric before molding.
As the air permeability of the cup part after molding, it is preferable that the air permeability measured by a KES-F8 air permeability tester is 0.025 KPa · s / m or less.

Moreover, when the said three-dimensional structure warp knitted fabric is used as a cup raw material of a brassiere, it is preferable that the thickness of a fabric is 2-6 mm, and it is especially preferable that it is 2-4 mm.
It is preferable that the thickness of the fabric is 2 to 6 mm. If the thickness is less than 2 mm, the shape stability and the compression resilience may be impaired or transparent, whereas if the thickness exceeds 6 mm. This is because the fabric may become heavy or the texture may deteriorate.
The thickness of the fabric is measured by the method described in the examples.

Furthermore, the three-dimensional structure warp knitted fabric can be used not only over the cup part but also over the cup part and part of the side part in contact with the cup part.
Further, as described above, the cup portion may be formed by sewing the three-dimensional structure warp knitted fabric without heating and pressing the three-dimensional structure warp knitted fabric.

  As clothing which has the said cup part, it can use suitably for outerwear, such as a shirt with a bra, innerwear, such as a camisole, a bra slip, and a body suit, a leotard, a swimsuit, etc. other than a brassiere.

As described above, according to the first invention, in the cross section in the course direction of the three-dimensional structure warp knitted fabric in which the first ground structure and the second ground structure, which are flat structures without openings, are connected by the connecting yarn, Since one ground structure has the loop which is not connected with the said connection thread | yarn with a predetermined space | interval, the air permeability of the 1st ground structure which is not connected with a connection thread | yarn improves compared with a 2nd ground structure. In addition, while the first ground structure has loops that are not connected by the connecting thread at a predetermined interval, the other second ground structure is all connected by one connecting thread, so that there is a gap between the connecting threads. Becomes larger and the air permeability between the connecting yarns is improved. Therefore, the air permeability is increased on the first ground structure side and at the same time, the air permeability is improved between the connecting yarns, and the air permeability of the entire three-dimensional warp knitted fabric can be improved. The feeling and stickiness can be reduced.

  In addition, as described above, since the number of connecting yarns includes a structure in which the connecting yarns protrude obliquely at different angles from the first ground structure toward the second ground structure without changing from the conventional number, The first and second ground structures are less likely to be displaced in the course direction, and excellent shape stability, thickness retention, and cushioning properties can be maintained.

Further, as described above, the first ground structure having a small number of connected knitting yarns of the connecting yarn has a softer texture than the second ground structure. A feeling can also be improved.
In addition, as described above, since the ground tissue portion to which the connecting yarn is not connected has good air permeability, by setting the first ground tissue having a loop not connected by the connecting yarn as a surface on the side in contact with the skin, Moisture from sweating can be dried quickly, reducing the feeling of stuffiness and stickiness.

  In addition, the textile product using the above-described three-dimensional warp knitted fabric has excellent cushioning properties, thickness retention properties, and shape stability, and can maintain a good state of air permeability and texture. While holding, there is no stuffiness or stickiness, unpleasant irritation to the skin, etc., and it is excellent in wearing feeling and use feeling.

  In particular, in a garment having a cup portion using at least the three-dimensional structure warp knitted fabric for the cup portion, the cup portion is formed even after the three-dimensional structure warp knitted fabric is heated and pressed to form a bulge portion of the cup portion. While maintaining excellent cushioning, thickness retention, and form stability, as well as maintaining good breathability and texture, while maintaining a proper correction of the breast shape, feeling of stuffiness and stickiness, There is no unpleasant irritation to the skin and it is extremely comfortable to wear.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 4 show a first embodiment of the present invention, in which a brassiere cup portion is formed by the three-dimensional warp knitted fabric 10 shown in FIGS. 1 and 2.

  The three-dimensional warp knitted fabric 10 of the first embodiment is knitted by a double raschel machine, and as shown in FIGS. 1 and 2, two ground textures, a first ground texture 11 and a second ground texture 12, 1 and a connecting thread 13 that connects the second ground structures 11 and 12.

  The double russell machine has a structure as shown in FIG. 3 and knitting the second ground structure 12 with ground yarns A1 and A2 introduced into the reed L-1 and reed L-2, respectively, The first ground structure 11 is knitted by the ground yarns A5 and A6 introduced into the reed L-6, and the first ground structure 11 and the second ground are formed by the connecting yarn 13 introduced into the reed L-3 and L-4. The organization 12 is linked and organized.

  Specifically, using the double raschel machine “RD6DPLM-77E-22G” (made by Meyer), the second ground texture 12 using polyester filament yarn of 56 dtex / 24f for the collars L-1 and L-2. The first ground structure 11 is knitted using 56 dtex / 24f polyester filament yarn on the heel L-5 and 84 dtex / 36f polyester filament yarn on the heel L-6, and the connecting yarn 13 is 110 dtex / 12f A polyester filament yarn is used for the ridges L-3 and L-4, and the first ground structure 11 and the second ground structure 12 are connected to produce a three-dimensional structure warp knitted fabric 10.

As shown in FIGS. 1 and 2, in the cross section in the course direction (the direction of arrow A in the figure) of the three-dimensional warp knitted fabric 10, the first ground structure 11 is connected and knitted with connecting yarns 13 every other loop. The loops 11a-2 that are not connected to the loops 11a-1 that are connected to each other are alternately present , and the first ground tissue 11 is a flat tissue that does not have an opening, while the second ground tissue 12 is also not open to the loop 12a. and continuous flat tissue, the loop 12a of all are connected knitted with connecting thread 13, relative to one loop 11a-1 which is connected knitting of the first ground structure 11, the two connecting yarn 13 It is structured to be connected and knitted at different angles.
In the first embodiment, the connection density of the connecting yarns 13 in the first ground structure 11 is 50%, and the swing width of the connecting yarns 13 is one needle and two needles.

The obtained three-dimensional warp knitted fabric has a fabric thickness of 2 to 6 mm, a permeability measured by a KES-F8 breathability tester of 0.02 KPa · s / m or less, and a mass (weight) of 250 to 370 g / m. ² .

As described above, the three-dimensional structure warp knitted fabric 10 of the first embodiment is a cross section in the course direction (arrow A direction) of the three-dimensional structure warp knitted fabric 10 in which the first and second ground structures 11, 12 are connected by the connecting yarns 13. The first ground texture 11 has the portions 11a-2 that are not connected by the connecting yarn 13 at one loop interval, so that the air permeability of the portion 11a-2 that is not connected by the connecting yarn 13 is improved. In addition, the first ground structure 11 has portions 11a-2 that are not connected by the connecting thread 13 at one loop interval, whereas the loops 12a of the second ground structure 12 are all connected by one connecting thread. The number of connecting yarns 13 connected to each of the first and second ground structures 11 and 12 is different, so that the gap 14 between the connecting yarns 13 is increased, and the air permeability between the connecting yarns is improved.
Therefore, the air permeability of the entire three-dimensional warp knitted fabric 10 can be improved by improving the air permeability between the portion 11a-2 and the connecting yarn 13 that are not connected by the connecting yarn.

  In addition, as described above, since the number of connecting yarns 13 is not changed from the conventional one, the connecting yarns protrude from the first ground structure 11 toward the second ground structure 12 at different angles. Further, it is difficult for the second ground structures 11 and 12 to be displaced in the course direction, and excellent shape stability, thickness retention, and cushioning properties can be maintained.

Furthermore, as described above, the feeling of wearing can be improved by making the surface of the first ground structure 11 with a small number of connected knitting yarns of the connecting yarn 13 into contact with the skin.
In addition, as described above, since the ground tissue portion 11a-2 to which the connecting yarn 13 is not connected has good air permeability, the surface of the first ground tissue 11 having the portion 11a-2 not connected by the connecting yarn 13 is used as the skin. By using the surface on the contact side, moisture due to perspiration can be quickly dried, and the feeling of stuffiness and stickiness can be reduced.

Then, the cup part 21 of the brassiere 20 as shown in FIG. 4 is produced from the three-dimensional structure warp knitted fabric 10.
The cup part 21 is produced by cutting the three-dimensional warp knitted fabric 10 and performing a heat press at a molding temperature of 230 ° C. and a molding time of 45 seconds to form a bulge part.
In addition, the surface of the first ground structure 11 having the loops that are not connected at predetermined intervals of the three-dimensional structure warp knitted fabric 10 is a surface in contact with the skin, and the second ground structure 12 surface to which all the loops are connected is the outer surface side. As the face.
The obtained cup portion 21 has a fabric thickness of 2 to 4 mm and a measured air permeability of 0.025 KPa · s / m or less by a KES-F8 air permeability tester.

  Further, as described above, even after the three-dimensional warp knitted fabric 10 is heated and pressed to form the bulged portion of the cup portion 21, the cup portion 21 retains excellent cushioning properties, thickness retention properties, and form stability. In addition, the breathability and texture can also be kept in a good state, so it maintains an appropriate correction for the shape of the breast, and it has excellent feeling of wearing without feeling of stuffiness, stickiness, unpleasant irritation to the skin, etc. The brassiere 20 having the cup portion 21 can be obtained.

It is a flat structure, and the first ground structure 41 is connected and knitted with the connecting yarns 43 every two loops, and the loops 41a-1 that are not connected to the connected loops 41a-1 exist every two loops, In the two ground structures 42, all the loops 42a are connected and knitted with the connecting threads 43, and the three connecting threads 43 are connected and knitted at different angles with respect to one loop 41a-1 to which the first ground structures 41 are connected. It has a structure to do.

The cup part 21 of the brassiere 20 is produced in the same manner as in the first embodiment except as described above.

In this state, the film was left at a temperature of 100 ° C. for 2 hours so that the thickness could be easily changed.
After 2 hours, the thickness immediately after removing the weight was taken as the thickness L2 after the test, and the thickness before placing the weight was taken as L1, and the thickness retention rate (%) was obtained from the following formula.
Thickness retention (%) = (L2 / L1) × 100

The three-dimensional structure warp knitted fabric of Example 1 was excellent in form stability and thickness retention, and maintained good cushioning properties. In addition, the air permeability was excellent. Therefore, when used in various textile products, moisture due to sweating can be quickly dried, and the feeling of stuffiness and stickiness can be reduced.
On the other hand, the three-dimensional structure warp knitted fabric of Comparative Example 1 was superior in form stability, thickness retention and cushioning properties, but was inferior to Example 1 in air permeability and stiff. For this reason, the air is not sufficiently circulated at the portion in contact with the skin, and the stuffiness may not be sufficiently eliminated and a sticky feeling may be felt.

  In addition, in the said embodiment, although the example which used the three-dimensional structure warp knitted fabric for the cup part 21 was demonstrated, it covers not only the cup part 21 but a part of the side part 22 which touches the cup part 21 and the cup part 21. Can also be used. The three-dimensional warp knitted fabric is also suitably used for textile products such as sports clothing materials, shoe materials and chair upholstery materials, as well as clothing having a cup portion such as a brassiere.
