Embodiment 1
[0082] (Preparation of yarn)
[0083] As the warp and weft, prepared were nylon 6,6, 72 filaments of single fiber with a circular cross-sectional shape and a single fiber fineness of 6.52 dtex, a total fineness of 470 dtex, and a tensile strength of 8.4 cN / dtex. 23.5% elongation, untwisted synthetic filament.
[0084] (weaving)
[0085] Using the above-mentioned yarns as the warp and weft yarns, a water jet loom was used to fabricate a fabric with a weaving density of both warp and weft yarns of 54 / 2.54 cm and a width of 200 cm. At this time, the warp tension was adjusted to 94 cN / thread, the shedding timing was set to 340 degrees, and the loom rotational speed was set to 600 rpm.
[0086] (scouring and heat setting)
[0087] Next, the obtained woven fabric was appropriately scoured by a conventional method under the conditions described in Table 1, and dried. Then, the base fabric whose surface temperature was kept at 42°C by the hot air dryer was heated at 180°C for 1 mi...
Embodiment 2
[0089] (Preparation of yarn)
[0090] As the warp and weft, the same synthetic fiber filaments as in Example 1 were prepared.
[0091] (weaving)
[0092] Next, weaving was performed in the same manner as in Example 1.
[0093] (scouring and heat setting)
[0094] Next, under the conditions described in Table 1, the obtained fabric was appropriately scoured and dried by the same method as in Example 1. Then, the base fabric whose surface temperature was kept at 65° C. by a hot air dryer was subjected to heat setting processing in the same manner as in Example 1.
Embodiment 3
[0103] (yarn preparation)
[0104] The warp and weft were prepared from nylon 6,6, composed of 136 single fibers with a single fiber fineness of 2.57 dtex in a circular cross-section, a total fineness of 350 dtex, a tensile strength of 8.4 cN / dtex, an elongation of 23.5%, and no twist. of synthetic filaments.
[0105] (weaving)
[0106] Using the above-mentioned yarns as the warp and weft yarns, a water jet loom was used to fabricate a fabric with a weaving density of both warp and weft yarns of 60 pieces / 2.54 cm and a width of 200 cm. At this time, the warp tension was adjusted to 70 cN / thread, the shedding timing was adjusted to 340 degrees, and the loom rotation speed was adjusted to 600 rpm.
[0107] (scouring and heat setting)
[0108] Next, under the conditions described in Table 1, the obtained fabric was appropriately scoured and dried by an ordinary method. Then, the base fabric whose surface temperature was kept at 44°C by the hot air dryer was heat-set at 160°C ...
