Embodiment 1
[0021] 2 / 1 Serge, the steps are as follows:
[0022] 1) Yarn forming method: blending 45% wool, 45% polyester staple fiber, and 10% polytrimethylene terephthalate (PTT) to obtain a single yarn twist of 680Z twist / m and a strand twist of 790S 56 Nm / 2 blended yarn with twist / m;
[0023] 2) Weaving method: use the yarn in step 1) as warp and weft to weave, the weave structure is 2 / 1 right twill, the ratio of the weaving upper machine width to the finished product width is 1.1, and the warp and weft density of gray cloth is 300× 240 pieces / 10cm;
[0024] 3) Finishing process: Boil the fabric at a high temperature above 80°C on single and double boiling equipment, shrink the width to 145-155cm after wet trimming, and pass 175°C, 35m / min, and set the door width on the machine at 152+2cm , and finally through 0.6-0.8Bar deburring to obtain a finished product with a width of 150cm and a density of 318×251 pieces / 10cm.
Embodiment 2
[0026] 2 / 1 Serge, the steps are as follows:
[0027] 1) Yarn forming method: blending 45% wool, 25% polyester staple fiber, and 30% dope dyed or stripe-dyed polytrimethylene terephthalate (PTT) polyester composite staple fiber to obtain single yarn twist 56 Nm / 2 blended yarn of 680Z twist / m and strand twist of 790S twist / m;
[0028] 2) Weaving method: the yarn in step 1) is used as warp and weft to weave, the organizational structure is 2 / 1 right twill, the ratio of the weaving upper machine width to the finished product width is 1.24, and the warp and weft density of gray cloth is 270 ×240 pieces / 10cm;
[0029] 3) Finishing process: On the continuous cooking equipment, pass through the high-temperature continuous cooking tank of 80°C-110°C at a speed of 25m / min, so that the fabric width shrinks to 165cm, and then continues to shrink effectively in the wet state, and pulls when shaping The width is 1-2cm, and the finished product with a width of 150cm and a density of 318×25...
Embodiment 3
[0031] 2 / 1 Serge, the steps are as follows:
[0032] 1) Yarn forming method: blending 50% wool, 20% polyester staple fiber, and 30% polytrimethylene terephthalate (PTT) polyester staple fiber to obtain a single yarn with a twist of 680Z twist / m, strand 56 Nm / 2 blended yarn with a line twist of 790S twist / m;
[0033] 2) Weaving method: use the yarns in step 1) as warp and weft yarns for weaving. The ratio is 1.24, and the warp and weft density of the gray cloth is 270×240 threads / 10cm;
[0034] 3) Finishing process: Boil the cloth at a high temperature above 80°C on the single and double boiling equipment, so that the width is reduced to 148-155cm, and it is finalized through 175°C, 35m / min, and a door width of 154cm on the machine, and finally through 0.6- After deburring at 0.8 Bar, a finished product with a width of 150 cm and a density of 318×251 strands / 10 cm was obtained.
