Embodiment 1
[0075] 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 100E1% and 0.5% of anionic surfactant at 140°C, hot calendering at 160°C was applied. The amount of silicone resin attached was 0.8 wt%.
[0076] 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 is 29.2%, and the tear strength is 10.5N in length and 12N in width.
[0077] The texture of the gray fabric is very good, and when this fabric is used in a down jacket, it is light, soft, a...
Embodiment 2
[0079] 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.
[0080] 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 is 4.5%, and the tear strength is 9.1N in the longitudinal direction and 8.2N in the transverse direction.
[0081] 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
[0083] 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.
[0084] 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 is 10.6%, and the tear strength is 10.1N in length and 11N in width. When the fabric is used in down jackets, it is light, soft and strong enough.
