Fiber with excellent contact and coolness

The present invention relates to a fiber which is excellent in contact feeling coolness, which is excellent in hand feeling and skin feel, and a fabric, a clothing material and a close-fitting body which are excellent in contact with the cool feeling using the fiber having excellent contact feeling of coolness. Clothing.

In recent years, as a close-fitting clothing for summer use, it has been studied to use a fiber which has a cool feeling and can provide a cool feeling when worn.

The method of producing such a fiber having excellent contact cooling feeling has conventionally been carried out by a method of improving the water absorption of the fiber or improving the thermal conductivity of the fiber.

The fiber which improves the water absorption property is, for example, a fiber which is formed by introducing a resin having a hydrophilic group such as a carboxyl group or a hydroxyl group.

The fiber which improves the thermal conductivity is, for example, a fiber composed of a resin in which a filler having high heat conductivity is kneaded, or a fiber coated with a surface on the surface.

However, when such a fiber is used, it is theoretically expected that a contact feeling can be obtained. However, when a person is subjected to a sensory test in practice, it is almost indistinguishable from the untreated person, and the feeling of contact with the coolness cannot be actually felt.

Patent Document 1 discloses a fiber having a cooling-contacting effect, in which a porous inorganic powder particle containing a water-absorptive polymer is held in a fiber. The fiber has a cool touch to the extent that it is actually felt. However, in order to obtain a sufficient contact cool feeling, it is necessary to contain a large amount of porous inorganic powder particles, and as a result, it may adversely affect the feeling of the palm and the touch of the skin, and it may not be used for the close-fitting clothing.

An object of the present invention is to provide a fiber having excellent contact with a cool feeling, and a cloth, a clothing material and a close-fitting clothing which are excellent in contact with the cool feeling and which are excellent in contact with the cool feeling, and which are excellent in contact with the cool feeling, can be in a functional grade. I feel the full contact with the cool feeling, and the feel and skin feel are excellent, which is very suitable for close-fitting clothing.

The present invention is a fiber containing a thermoplastic elastomer and an inorganic filler. Hereinafter, the present invention will be described in detail.

As a result of intensive research, the present inventors have found that when the fiber obtained by spinning a thermoplastic elastomer is used for a clothing, it has an excellent cold contact feeling. However, when the fiber containing the thermoplastic elastomer is used for clothing, it has an excellent contact feeling of coolness, but when it is wetted by sweat or the like, it becomes sticky or deteriorates the touch of the skin, especially When intimate clothing or the like directly contacts the skin material, it may cause discomfort and cause new problems. Therefore, the inventors of the present invention have found that by adding an inorganic filler to the fiber containing the thermoplastic elastomer and using it for clothing, it is possible to prevent discomfort during wetting and to impart excellentness. Since the hand feels and the touch of the skin, it is particularly suitable for clothing materials such as close-fitting clothes, thereby completing the present invention.

Among the thermoplastic elastomers, the polyether block phthalamide copolymer represented by the following formula (1) can be obtained by providing fibers excellent in contact cooling feeling, excellent in spinning property, and light in weight. It is especially good for lightweight fabrics, clothing, and clothing. Among the commercially available ones of the polyether block phthalamide copolymers, for example, Pibacs (manufactured by Achema Co., Ltd.) and the like can be mentioned.

In the formula (1), PA represents polyamine and PE represents a polyether.

The resin component contained in the fiber having excellent contact cooling feeling of the present invention may be a thermoplastic elastomer alone, but a fiber containing only a thermoplastic elastomer as a resin component generally has a sticky feeling and is spun. It is difficult to carry out, so other resins than the thermoplastic elastomer may be used in combination.

The fiber of the present invention having excellent contact coolness further contains an inorganic filler.

By including the inorganic filler, fine irregularities are formed on the surface of the fiber, and the surface of the fiber is modified. Therefore, it is possible to prevent the stickiness of the thermoplastic elastomer from being wet, and to greatly improve the contact with the skin when used in clothing. Skin touch, or skin detachment when undressing. Further, since the stickiness of the fibers can be reduced, the spinning property in the production of the strands can be improved.

In addition, since the fiber having excellent contact with the cool feeling of the present invention is not provided for the purpose of imparting a cool feeling to contact, but is added with an inorganic filler for the purpose of preventing stickiness during wetting, it is not necessary to add a large amount of inorganic filler, even if When used in clothing, etc., it does not adversely affect the feeling of the palm and the touch of the skin.

When the thickness is less than 0.20 μm, the effect of improving the feeling of discomfort such as stickiness during wetting is insufficient, and when it exceeds 3.00 μm, the hand feeling and the skin feel when the fabric is used are deteriorated, or the fiber strength is lowered.

A preferred lower limit of the content of the inorganic filler is 2% by weight, and a preferred upper limit is 30% by weight. A more preferable upper limit is 7% by weight. If it is less than 2% by weight, the effect of improving the feeling of discomfort such as stickiness during wetting is insufficient, and if it exceeds 30% by weight, the strength of the fiber is lowered. Moreover, the spinning property is also deteriorated.

The fiber having excellent contact cooling feeling of the present invention may be composed only of fibers containing the above thermoplastic resin and inorganic filler, or may be interwoven with other fibers to improve skin contact without impairing the object of the present invention. The necessary conditions for feeling close to clothing. The other fibers are not particularly limited, and examples thereof include polyamine-based resins such as nylon 6 and nylon 12; polyester, cotton, and rayon.

In the fiber of the present invention having excellent contact cooling feeling, _a preferred lower limit of the q _{m a x} value is 0.20 J/sec/cm ² . If the q _{m a x} value is less than 0.20 J/sec/cm ² , even if a functional test is performed, most of the people will not feel the contact feeling. A more preferable lower limit is 0.21 J/sec/cm ² , and a still lower limit is 0.22 J/sec/cm ² .

In addition, in the present specification, the q _{m a x} value means that a predetermined amount of heat is accumulated in a hot plate having a constant area and a certain mass, and after the contact with the surface of the sample, the accumulated heat is immediately moved to the sample on the low temperature side. The peak of the heat flow. The value of q _{m a x} can be considered as the temperature of the sample taken away from the sample during the dressing. It can be seen that the larger the value of q _{m a x} is, the larger the body temperature is taken when the dressing is taken, and the higher the contact feeling is.

With the present invention is excellent in cool feeling of contact with the fibers, the preferred lower limit of the thermal conductivity of ^{1 × 10 - 3 ℃ / W} . m ² . Thermal conductivity can also be considered as one of the important parameters corresponding to the contact cooling. If the thermal conductivity is less than 1 × 10 ^{- 3} °C / W. m ² , even if the functional test is carried out, most people will not feel the contact coolness.

In the present specification, the thermal conductivity is obtained by superimposing a hot plate on a sample placed on the sample stage, and measuring the heat loss rate after the temperature of the hot plate is stabilized to a predetermined temperature, and calculating it according to the following formula (2).

Thermal conductivity (W/cm/°C)=W. D/A/△T(2)W: heat flow rate (J/sec) D: thickness of sample (cm) A: hot plate area (cm ² ) △ A: temperature difference between sample stage and hot plate (°C )

In the fiber having excellent contact cooling feeling of the present invention, the preferred lower limit of the wet sliding starting angle is 20°, and the preferred upper limit is 25°. If it is less than 20°, the feel and the touch of the skin will be deteriorated. If it exceeds 25°, the skin detachability will be lowered when used in close-fitting clothing.

The excellent properties of the plastic elastomer and the formation of a core-sheath structure fiber having good dyeability.

In general, thermoplastic elastomers are difficult to dye using acid dyes or cationic dyes because they do not have a color-receiving position for dyeing or have a color-receiving position. For such a problem, Japanese Laid-Open Patent Publication No. 2003-247177 discloses a method of dyeing a thermoplastic elastomer such as a polyurethane using a disperse dye. Further, a method of introducing a color-receiving position into a thermoplastic elastomer resin to dye it, a method of coloring a particle of a thermoplastic elastomer resin containing an inorganic pigment and dyeing it with a stock solution, Various methods, such as a method of mixing a polyamidamide-based resin in a polyamide-based elastomer resin as a thermoplastic elastomer resin, to make it dyeable. However, the problem of such dyeing cannot be adequately solved by either method.

On the other hand, when the core-sheath type composite fiber is used for dyeing, the dye can be dyed by a core portion containing a dyeable resin by a sheath portion containing a thermoplastic elastomer (having almost no color receiving position). Therefore, when the core-sheath type composite fiber is used for dyeing, it is possible to perform good dyeing even by a dye such as an acid dye or a cationic dye, and it is possible to further exhibit excellent dyeing as compared with a fiber using a thermoplastic elastomer alone. Sex.

The core-sheath type composite fiber preferably contains a dyeable resin in the core.

The dyeable resin is not particularly limited as long as it can be dyed and can be used as a fiber, and examples thereof include a polyamide resin such as nylon 6 or nylon 12, and a polyester resin such as PET, PBT or PTT. , other rayon, acrylic, etc. Among these, a polyamide resin is preferred.

For example, the cross-sectional shape when the fiber is cut perpendicularly to the longitudinal direction of the fiber may be a circle or may be an ellipse or the like. Further, it may be a fiber having a concentric core-sheath structure in which the core portion and the sheath portion are concentrically formed, or a fiber having an eccentric core-sheath structure in which the core portion and the sheath portion are eccentric. Further, it is also possible to have a structure in which a plurality of core portions are present when the longitudinal direction of the fibers is perpendicularly cut.

In the core-sheath type composite fiber, a preferred upper limit of the thickness of the sheath portion is 20 μm. When it exceeds 20 μm, it is difficult for the dye to pass through the sheath at the time of dyeing, and the dyeability is insufficient. Further, a preferred lower limit of the thickness of the sheath portion is 2 μm. If it is less than 2 μm, the sheath portion is too thin, and the contact cooling effect cannot be exerted.

When the core-sheath type composite fiber has a concentric core-sheath type structure in which the core portion and the sheath portion are formed in a concentric shape, a preferred lower limit of the ratio of the core diameter to the sheath portion thickness (core portion/sheath portion) is 5 /20, the upper limit is 46/2. If it is less than 5/20, the ratio of the sheath portion is large, and the dyeability is insufficient. When it exceeds 46/2, the contact feeling and softness are lowered.

The core sheath type composite fiber preferably has a lower limit of q _{m a x} of 0.17 J/sec/cm ² . If the value of q _{m a x} is less than 0.17 J/sec/cm ² , it is the same grade as polyester or nylon, and even if a functional test is performed, most people will not feel the contact feeling.

For example, it is possible to melt-spin using the obtained resin particles after preparing resin particles containing a thermoplastic elastomer and an inorganic filler. A conventional method such as a method of producing a yarn.

Further, the core-sheath type composite fiber can be produced by, for example, a method of melt spinning, by putting resin pellets containing a dyeable resin, a thermoplastic elastomer, and an inorganic filler into a composite spinning device.

The fiber having excellent contact feeling of the present invention can be used as a fabric such as a knitted fabric, a woven fabric, or a non-woven fabric. It is also one of the inventions to use such a fabric having excellent contact coolness, which is composed of fibers having excellent contact cooling feeling of the present invention.

The fabric having excellent cold contact feeling of the present invention can be composed only of the fibers having excellent contact with the cool feeling of the present invention, and can be blended with other fibers to improve the skin feel and the like without hindering the object of the present invention. The necessary conditions for clothing. The other fibers are not particularly limited, and examples thereof include polyamine-based resins such as nylon 6 and nylon 12; polyester, cotton, and rayon.

By using the fiber having excellent contact with the cool feeling of the present invention or the cloth having excellent contact with the cool feeling of the present invention as a clothing material, it is possible to produce a clothing material which can prevent discomfort during wetness and which is excellent in hand and skin feel. The garment material having excellent contact coolness is also one of the inventions.

Since the fabric having excellent contact with the cool feeling of the present invention contains a thermoplastic elastomer, it can cause a cool and cool feeling when worn, and can impart a cooling sensation. In addition, by containing an inorganic filler, it is non-sticky when wet, and has excellent skin feel and feel, making it ideal for close-fitting clothing.

The fabric having excellent contact with the cool feeling of the present invention may be a fiber having excellent contact feeling and coolness as a whole, but in particular, a fabric having excellent coolness by a knitted fabric of a double-sided woven structure is preferably used in the total number of loops. 30 to 70% of the yarns which are composed of fibers having excellent contact with the coolness and the fibers having excellent contact with the coolness are arranged only on the skin side (hereinafter also referred to as cool sensation materials).

The clothing material having excellent contact with the cool feeling of the present invention is in a clothing composed of a knitted fabric of a double-faced woven structure, and the ratio of the number of yarn loops formed by the fibers having excellent contact with the cool feeling is within a certain range, and such a ratio The yarn loops made of fibers with excellent contact and coolness are placed only on the side of the skin that directly contacts the skin, and can be made into a fabric that has an anti-disgusting effect due to excessive sweating.

In recent years, various high-performance clothing materials have been developed and proposed as close-fitting clothing to be worn during sweating in summer or exercise. For example, a functional material such as a hydrophobic fiber such as polyester has been proposed. Further, the method of improving the gas permeability by using the hydrophobic fibers in combination with cotton, the method of making the structure of the cloth into a net structure, or the buckling weaving by the flat knitting and warp knitting, thereby improving the gas permeability In the discussion, Japanese Laid-Open Patent Publication No. 2003-155669 discloses a cloth which is modified by attaching a hydrophilic chemical substance to the surface of the hydrophobic fiber constituting the cloth. However, such a cloth composed of hydrophobic fibers can effectively dissipate the generated heat, but when the skin or clothes are wetted by sweating, in addition to the discomfort caused by the wet feeling, Cloths tend to stick to the skin and cause problems that are difficult to move.

On the other hand, in the case of the knitted fabric of the double-woven fabric structure, the cool fabric can be worn by controlling the ratio of the number of loops formed by the fibers having excellent contact with the cool feeling within a predetermined range. It is a cool feeling or a cool feeling, and it can prevent the discomfort caused by the moist feeling when sweating, or prevent the skin from deteriorating and make the cloth adhere to the skin. In addition, by placing the yarn loop formed by the fiber having excellent contact with the cool feeling only on the skin side, the fiber having excellent contact with the cool feeling can be directly contacted with the skin, and the fabric having excellent cooling feeling and cool contact feeling can be obtained.

The preferred lower limit of the ratio of the loops of the cooling sensation material and the fiber having excellent contact with the cool feeling is 30% of the total number of loops, and the upper limit is preferably 70%. If it is less than 30%, the effect of cooling and the feeling of contact with the coolness is insufficient. If it exceeds 70%, it may be uncomfortable due to wetness when sweating, and it may be difficult to adhere to the skin due to the cloth. action. A lower limit is 33%, and a lower limit is 67%.

Further, when the skin side of the refreshing sensation material is composed only of the yarn loop composed of the fiber having excellent contact with the cool feeling, the preferred lower limit of the yarn loop ratio of the fiber having excellent contact feeling coolness is 50% of the total number of laps. The preferred upper limit is 70%, and when the skin side is composed of fibers having excellent contact cooling and hydrophobic fibers, the preferred lower limit of the ratio of the loops formed by the fibers having excellent contact cooling is 30%, preferably upper limit. It is 50%.

In this case, the fiber containing the thermoplastic elastomer contains a polyamine amine elastomer A having a hard segment of polyamine 12 and a soft segment of polyethylene glycol, and a hard segment of polyamine. The fiber of the mixed resin of the polyamidamide-based elastomer B having a soft segment of polytetramethylene glycol is preferred because it can provide an extremely excellent contact cooling feeling and is excellent in both moisture absorption and release properties and diffusion properties.

Further, the fiber containing the thermoplastic elastomer is preferably a fiber of a content of 60% by weight or more of Pibacs 1014SA01 (manufactured by Atofina Japan Co., Ltd.) of a polyether block phthalamide copolymer, and is porous. The fiber which is hydrophilized on the surface is added to an inorganic material such as polyester or nylon, and an inorganic substance such as titanium oxide in an amount of 1 to 5% by weight is added to improve the heat-contacting fiber.

In the cooling sensation material, the fiber having excellent contact with the cool feeling may be used in combination with other fibers when the thickness of the cloth is to be made as thin as possible. At this time, the preferred lower limit of the content of the thermoplastic elastomer in the fiber having excellent contact cooling feeling is 50% by weight. If it is less than 50% by weight, the contact feeling may not be sufficiently exerted.

In the cooling sensation material, it is preferable that the yarn ring composed of the fiber having excellent contact with the cool feeling is disposed only on the skin side. With this configuration, when the cool sensation material is worn, the yarn loop composed mainly of fibers having excellent contact with the cool feeling is in contact with the skin, so that the contact feeling of coolness and the coolness can be caused, and the hydrophobic fiber is formed by the latter. The yarn loop is placed on the outside to enhance the heat and moisture diffusion and evapotranspiration of the skin.

In the cooling sensation material, the yarn loop other than the fiber yarn loop having excellent contact with the cool feeling is preferably a yarn loop composed of a hydrophobic fiber.

In the cool sensation material, as described above, since the yarn loop composed of the fiber having the excellent contact cool feeling is disposed only on the skin side, the yarn loop composed of the hydrophobic fiber is mainly disposed on the outer side. Thereby, the evapotranspiration of the sweat can be promoted, and the generated heat is dissipated with good efficiency.

In the present specification, the term "hydrophobic fiber" refers to a chemical fiber having a predetermined moisture content of 5.0% or less. Specifically, for example, polypropylene (common moisture content: 0%), polyester (0.4%), and acrylic resin (for example) 2.0%), nylon (4.5%), vinyl nylon (5.0%) and other fibers. These may be used alone or in combination of two or more. In addition, the specific moisture content refers to the moisture content at 20 ° C and 65% RH.

In the cooling sensation, it is also possible to contain fibers having excellent contact with coolness and fibers other than hydrophobic fibers, such as natural fibers composed of cotton or hemp, or semi-synthetic fibers such as rayon or acetate. .

Fig. 3 is a schematic view showing the flow of heat and water vapor emitted from the skin when the cooling sensation material is worn.

As shown in Fig. 3, the heat and water vapor emitted from the skin are firstly passed through a portion 12 which is made of fibers having excellent contact with the cool feeling. At this time, the fibers having excellent contact with the cool feeling absorb heat and absorb water. Then, it is not possible to dissipate heat and evade to the outside by diffusing the portion 13 made of the hydrophobic fibers by heat absorption, heat absorption and moisture of the fibers having excellent contact cooling. Further, in Fig. 3, only the portion in which the fiber having the excellent contact cooling feeling is knitted and the portion in which the hydrophobic fiber is knitted is shown, and in the portion composed only of the portion in which the hydrophobic fiber is knitted. The heat and water vapor emitted by the skin are diffused, dissipated, and evaporated to the outside.

In the cooling sensation, the ratio of the portion prepared by the fiber having excellent contact cooling feeling to the portion of the portion in which the hydrophobic fiber is knitted is within an appropriate range, so that a cool feeling and a refreshing feeling can be imparted when worn. It can prevent the discomfort caused by the moist feeling when sweating, and prevent the skin from deteriorating and make the cloth adhere to the skin.

The cooling sensitizing material preferably has a lower limit of air permeability of 200 cm ³ /cm ² /sec and a preferred upper limit of 500 cm ³ /cm ² /sec. If it is less than 200cm ³ /cm ² /sec, the gas permeability is poor, which will hinder the heat dissipation of the skin and the evapotranspiration of the sweat. If it exceeds 500cm ³ /cm ² /sec, the movement of heat or moisture will pass through the fabric. It cannot be fully carried out, and conversely it may cause outside air to enter.

Further, the gas permeability can be measured by a method specified in JIS L 1096 A by using a Frazier type gas permeability tester.

The preferred lower limit of the refreshing coating material is 90 g/m ² , and the upper limit is preferably 200 g/m ² . If it is less than 90 g/m ² , heat and moisture are hard to move, and the cooling feeling effect is lowered. When it exceeds 200 g/m ² , the weight and heat transmission impedance increase, and the cooling sensibility is lowered.

The knitted fabric of the double-woven structure can be produced by adjusting the amount of knitting needles when knitting a yarn loop using a circular rib knitting machine. Specifically, for example, it is produced by a method of knitting a yarn loop (composed of a fiber having excellent contact with a cool feeling) by 30 to 70%.
