Embodiment 1
[0102] The used warp yarn and weft yarn are nylon 66 filament raw yarn (the monofilament section is a circular section) with a denier of 310dtex / 96f, a tensile strength of 8.6cN / dtex, a tear elongation of 20%, and a boiling water shrinkage of 9.0%. The weaving density is 66 / inch, after weaving plain weave with water-jet loom, directly pass through the hot water shrinkage tank without drying, and then control the temperature T1 of the first stage to 120 by using a two-stage suction drum dryer. °C, the drying process of controlling the temperature T2 of the second stage to 125 °C is completed. The physical properties of the obtained base fabric are shown in Table 1.
[0103] As the sewing thread, nylon 66 thread with a fineness of 920dtex, a tensile strength of 8.6cN / dtex, and a tear elongation of 22% is used for both the upper and lower threads. Flat seams are used, and the sewing needle density is 4.5 needles / cm. The above-mentioned base fabric is used. A sewn sample simulati...
Embodiment 2
[0105] A base fabric and a sewn sample were produced in the same manner as in Example 1 except that the warp and weft weave density was 63 threads / inch. Table 1 shows the results of evaluating the produced base fabric and sewn samples in the same manner as in Example 1.
Embodiment 3
[0107]Except that the used warp yarn and weft yarn are nylon 66 fine filament raw yarn (single filament section is a circular section) with denier 270dtex / 84f, tensile strength 8.6cN / dtex, tear elongation 19%, and boiling water shrinkage 9.0%. Except that the density was 70 counts / inch, base fabrics and sewing samples were produced in the same manner as in Example 1. Table 1 shows the results of evaluating the produced base fabric and sewn samples in the same manner as in Example 1.
