Embodiment 1
[0029] The warp and weft yarns are all made of nylon 66 filaments with a total fineness of 350dtex, a number of 136, and a circular cross section. Water-jet loom is used to weave plain weave, and a yarn pressing bar is added under the sheet warp between the heald frame of the loom and the back beam of the loom. Wherein, the specific position of the yarn pressing rod is that the horizontal position is located at 40 cm away from the back beam; the upward pressing displacement is 4 cm away from the warp position line. A fabric with a warp density of 59 threads / inch and a weft density of 59 threads / inch was obtained. The physical properties of the obtained fabrics were evaluated, and the relevant physical properties are shown in Table 1.
Embodiment 2
[0031] The warp and weft yarns are all made of nylon 66 filaments with a total fineness of 350dtex, a number of 136, and a circular cross section. Water-jet loom is used to weave plain weave, and a yarn pressing bar is added under the sheet warp between the heald frame of the loom and the back beam of the loom. Wherein, the specific position of the yarn pressing rod is that the horizontal position is located at 45 cm away from the back beam; the upward pressing displacement is at 6 cm away from the warp position line. A fabric with a warp density of 59 threads / inch and a weft density of 59 threads / inch was obtained. The physical properties of the obtained fabrics were evaluated, and the relevant physical properties are shown in Table 1.
