Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a stretchable three-layered raised fabric using core spun yarn.

<Relationship with conventional technology> Conventionally, as stretch fabrics using spandex yarn, many interwoven fabrics of polyester cotton blend yarn and spandex yarn have been woven for the purpose of stabilizing the dimensions of the fabric and improving the strength when made into thin fabrics. Ta. However, the raised fabric obtained by raising the mixed woven fabric was susceptible to pilling and could not be commercialized. In addition, woven fabrics of core yarn and cotton yarn with spandex yarn in the inner layer and cotton fiber in the outer layer,
Pilling did not occur, but width setting properties were poor, shrinkage over time and washing were large, and recovery from stretching was poor. In addition, the woven fabric of core yarn and cotton yarn, which has spandex yarn in the inner layer and polyester/cotton blend fiber (blend ratio 65:35) in the outer layer, has good width setting properties, small shrinkage over time, and small shrinkage after washing. Although the stretch recovery property was good, pilling occurred.

<Object of the invention> The present invention improves the conventional stretchable raised fabric,
Good width setting properties, less shrinkage over time and after washing.
To obtain a raised fabric using spandex yarn that has excellent dimensional stability, excellent elongation recovery, strong fabric strength, and less occurrence of pilling.

<Structure of the Invention> The present invention is characterized in that the warp or weft is provided with at least core spun yarn having a stretchable three-layer structure in which the inner layer is made of spandex, the middle layer is made mainly of synthetic fibers, and the outer layer is made mainly of natural fibers or regenerated cellulose fibers; This is a raised fabric that is woven with non-stretchable yarns arranged in the weft or warp yarns, and is also raised. The fiber thickness of the spandex forming the inner layer of the three-layer core spun yarn is 10 to 280 deniers, preferably 30 to 140 deniers. The synthetic fibers forming the middle layer are regular polyester fibers, modified polyester fibers such as disperse dye easily dyeable polyester fibers, cationic dyeable polyester fibers, cationic pressure dyeable polyester fibers, copolymer type polyester fibers, and nylon 6. , polyamide fibers such as nylon 6-6 are preferred, and blends with natural fibers may also be used. The fiber thickness is preferably 0°1 to 4 deniers, more preferably 0.5 deniers.
~2 denier. The natural fiber or regenerated cellulose fiber forming the outer layer is preferably cotton fiber, wool fiber, rayon, strong rayon, or polynosic fiber, and may be a blend of these fibers.The fiber thickness of the rayon or regenerated cellulose fiber is 0. .5 to 4.0 denier is preferred.

These three-layered core spun yarns can be obtained, for example, by the following method. When producing a spun yarn by passing the roving from the sliver, a sliver of mainly synthetic fibers is overlapped in the center of the sliver of mainly natural fibers that is being drafted or in the center of the regenerated cellulose fibers, and then a sliver is created. Both are drafted together to form a roving, and then, in the spinning process, the roving is drafted 15 to 40 times, and during spinning, the spandex is stretched 2 to 5 times by a roller roller. It can be obtained by supplying it just beforehand. The core spun yarn count of the three-layer structure is cotton count 4 to 60.
'S/I is preferable, more preferably 10 to 40'S/I
It is I. The mixing ratio of synthetic fibers in the three-layer core spun yarn is preferably 10 to 5 o-arc, more preferably 15 to 3 o-arc.

If the number of synthetic fibers exceeds 50 fleas, the synthetic fibers will come out on the surface of the yarn and the pilling property will decrease during raising, and if it is less than 10 seconds, the setting property will deteriorate and the strength will decrease, which is not good.

The core spun yarn number of the three-layer structure as described above is arranged in the warp or weft yarn. The other weft or warp yarns are provided with non-stretchable yarns. Non-stretchable yarns include cotton yarn, wool,
It may be a natural fiber yarn such as hemp or a blend thereof, or a blend yarn of natural fiber or regenerated cellulose fiber and synthetic fiber. Further, the core spun yarn may have a two-layer structure in which the outer layer is mainly natural fibers or regenerated cellulose fibers, and the inner layer is mainly synthetic fibers. The natural fibers forming the outer layer are preferably cotton fibers or wool fibers, and the regenerated cellulose fibers are preferably 0.5 to 4 denier rayon, strong rayon, or polynosic fibers, or blended fibers thereof may be used. In this case, the blending rate does not matter. The synthetic fibers forming the inner layer may be of any kind, but in particular, regular polyester fibers, disperse dye-dyable polyester fibers, cationic dye-dyable polyester fibers, cationic pressure-dyable polyester m fibers, copolymer type polyester Iam, etc. Polyamide fibers such as modified polyester alJI, nylon 6, and nylon 6-6 are preferred, and blends with natural fibers may also be used. The core spun yarn count of the three-layer structure is preferably 4 to 60'S/I, more preferably io
The two-layered core spun yarn having a diameter of ~40'8/I is obtained by the following method. When producing a spun yarn by passing the roving from the sliver, the mainly natural fibers being drafted (D Overlap the slivers and connect both -m
It is drafted into roving yarn, and then sent to a spinning machine to become core spun yarn.

Particularly preferred non-stretchable yarns are cotton yarn, core spun yarn with a two-layer structure, and wool yarn.

Furthermore, the three-layer structure core-spun yarn may be arranged in the warp or weft, or the three-layer structure core-spun yarn may be arranged in all the warp or weft yarns, or the three-layer structure core-spun yarn may be arranged in the warp or weft. One or more elastic threads may be alternately arranged. For example, when A is a core spun yarn with a three-layer structure and B is a non-stretchable yarn, AAAA...
ABAB..., ABBABB..., AABAAB. These yarns are arranged in the warp and weft for weaving, and the weaving structure may be any one suitable for raising, such as plain weave, satin weave, twill weave, or variations thereof.

The weaving density may be within the range of ordinary textiles and is not particularly limited.

The raising may be performed at the greige stage, or may be performed before or after dyeing, or at any step. Also,
Shearing may also be performed. The raising method may be any commonly used raising machine, such as a cloth raising machine or an emery raising machine.

<Effects of the Invention> The raised fabric of the present invention has good width setting properties, little shrinkage over time and washing, excellent dimensional stability, excellent elongation recovery, and strong fabric strength. Moreover, it is a raised fabric that is stretchable in the warp direction or the weft direction with less occurrence of pilling.

Table #1 As is clear from Table 1, Comparative Example 1, in which the core yarn was made of spandex fiber yarn for the inner layer and cotton fiber for the outer layer, had poor width setting properties and a high shrinkage rate over time and washing shrinkage rate. Furthermore, although the elongation rate was high, the elongation recovery rate was poor. However, the occurrence of pilling was small, and the fabric was a raised fabric with good and bad elasticity. In addition, Comparative Example 2, in which the inner layer was made of spandex fiber yarn and the outer layer was made of a blended fiber of polyester fiber and cotton fiber, had excellent width setting properties, shrinkage rate over time, shrinkage rate after washing, and elongation recovery rate. The occurrence of pilling was large and the product value was low. In contrast, Examples 1 to 3, which are the raised fabrics of the present invention, have good width retention, low shrinkage over time and low settling shrinkage, low pilling, and excellent stretch recovery. It was a brushed fabric with excellent properties.
