Embodiment 1
[0070] As the fiber, polyhexamethylene adipamide continuous fiber was used, and it was a drawn yarn with a fineness of 44 dtex and a number of single yarns of 34. The tanδ(max) of this fiber was 0.04, the Tmax was 110°C, and the ratio S was 0.00036 [1 / °C]. For warp yarns, the fibers are aligned without twist and sizing to form a warp bundle, and for weft yarns, the fibers are wound without twist and sizing and directly supplied from packages. As the selvage portion reinforcing thread, 8 polyhexamethylene adipamide continuous fibers with a fineness of 22 dtex were used to weave with a water-jet loom under the condition that the number of warp yarns inserted into the reed was 1 per reed tooth. The obtained fabric was scoured with warm water at 60° C. by the usual method, and then dried at 80° C. using a drum dryer. The cloth width of the produced fabric is 2.1m, and the warp yarn density of the fabric is 160 threads / 2.54cm in the central part, 162 threads / 2.54cm at the position...
Embodiment 2
[0072] In Example 1, fabrics were obtained in the same manner except that calendering was performed after weaving, scouring, and drying. Calendering was performed under the conditions of a feed rate of 10 m / min, a metal roll temperature of 180° C., and a pressure of 300 N / cm. Regarding the upper and lower calender rolls sandwiching the fabric, the upper heating metal roll has a diameter of 12 cm, and the lower roll has a paper surface and has a diameter of 24 cm, and the surface speeds of these two rolls are the same. The Shore hardness of the paper roll surface was 65. The warp density of the produced fabric was 157 yarns / 2.54 cm at the central portion and 160 yarns / 2.54 cm at a position 5 cm from the selvedge end, and the value M was 0.019. In addition, the spread rate is 0.5, and the bleeding index N when printing on the surface smoothed by heating calendering roll processing is 0.2, and the ratio of the bleeding index (N (center) / N (end) ) is 0.9. The quality of the bar...
Embodiment 3
[0078] As the fiber, polyhexamethylene adipamide continuous fiber was used, and it was a drawn yarn with a fineness of 470 dtex and a number of single filaments of 136. The tanδ(max) of this fiber was 0.03, the Tmax was 115°C, and the ratio S was 0.00026 [1 / °C]. For warp yarns, the fibers are straightened without twist and sizing to form a warp bundle, and for weft yarns, the fibers are wound without twist and sizing and directly supplied from a package. As the selvage portion reinforcing thread, 8 polyhexamethylene adipamide continuous fibers with a fineness of 67 dtex were used, and the number of warp yarns inserted into the reed was 1 per reed tooth, and weaving was carried out by a water jet loom. The obtained fabric was scoured with warm water at 60° C. by the usual method, and then dried at 80° C. using a drum dryer. Then, calendering is performed. Calendering was carried out under the conditions of a feed rate of 18 m / min, a metal roll temperature of 180° C., and a pr...
