Embodiment 1

[0074] Water jet loom is used for weaving, warp and weft are polyester filaments with intrinsic viscosity [η] of 0.85 and 11 decitex 10 filaments, weaving figure 1 lattice weave fabric. The obtained fabric is scoured and pre-shaped according to the usual method, dyed with a liquid flow dyeing machine, dried, and then processed by the DIP-NIP method. Nikka Chemical Co., Ltd.’s Nikka Silicone DM- After drying the emulsion of 100E 1% and 0.5% of anionic surfactant at 140°C, it was subjected to hot calendering at 160°C. The amount of silicone resin attached was 0.8 wt%.

[0075] The characteristic of the fabric obtained is as shown in table 1, and the weight per unit area of ​​fabric is 32g / m 2 , the number of intersections of warp and weft is 60025 / inch 2 , the proportion of non-constrained points was 29.2%, and the tear strength was 10.5N in the longitudinal direction and 12N in the transverse direction.

[0076] The texture of the gray fabric is very good, and when this fab...

Embodiment 2

[0078] Warp and weft use polyester filaments with a W-shaped cross-section whose intrinsic viscosity [η] is 0.87 and 17 decitex 18 filaments have a profile degree of 3.2, according to figure 2 Weaving and processing were carried out in the same manner as in Example 1 except that the weave was woven.

[0079] The characteristic of the obtained fabric is as shown in table 1, and the weight per unit area of ​​fabric is 31g / m 2 , the number of intersections of warp and weft is 44000 / inch 2 , the proportion of non-constrained points was 4.5%, and the tear strength was 9.1N in the longitudinal direction and 8.2N in the transverse direction.

[0080] The texture of the gray fabric is very good, and when the fabric is used in a down jacket, it is light, soft, and strong enough.

Embodiment 3

[0082] The warp uses polyester filaments with a W-shaped cross-section whose intrinsic viscosity [η] is 0.87 and 24 decitex 18 filaments with a degree of irregularity of 3.2, and image 3 Weaving and processing were carried out in the same manner as in Example 1 except that the weave was woven.

[0083] The properties of the resulting fabric are shown in Table 1, and the weight per unit area of ​​the fabric is 37g / m 2 , the number of intersections of warp and weft is 30960 / inch 2 , the proportion of non-constrained points was 10.6%, and the tear strength was 10.1N in length and 11N in width. When the fabric is used in down jackets, it is light, soft and strong enough.

Abstract

Disclosed is a thin woven fabric wherein thermoplastic synthetic fibers of fineness from 5 to 30 dtex are disposed in at least some of the warp and weft threads of a woven fabric and the number of intersections of the warp and weft threads of said woven fabric is from 23 000 to 70 000 / 2.54 cm2. Said woven fabric in the thin woven fabric is subjected to a silicon resin treatment.

Description

technical field [0001] The present invention relates to a thin fabric used for fabrics for down jackets, thin sportswear such as windproof sportswear, fabrics for sleeping bags, quilts, or fabrics for inner bags. More specifically, the present invention relates to a thin fabric that is lightweight and very thin, but also excellent in tear strength and abrasion strength, and sports clothing, quilts, etc., or inner bag fabrics using the thin fabric. Background technique [0002] Conventionally, from the viewpoint of ease of movement, fabrics for sportswear have been desired to be lightweight and thin and have excellent tear strength. In addition, in the use of quilt fabrics such as quilt covers and quilt linings, in order to reduce the load during sleep, the load when the quilt is put down, or for use in sleeping bags, it is desired that the fabric is lightweight, thin, and maintains tear strength. However, when the fineness of the yarn constituting the woven fabric is reduce...
