Embodiment 1
[0019] Embodiment 1: Processing of cupro ammonia filament blue yarn-dyed high-grade fabric whose fabric specification is CPT100 / 2*CU100D / 60F 150*100.
[0020] In the fabric specifications of Example 1, CPT100 / 2 refers to compact spinning pure cotton 100 inch strands, CU100D / 60F refers to cupro ammonia yarn with a yarn count of 100D and a hole number of 60F. The fabric composition is: 55% cotton, 45 % cupro fiber. The processing process of the fabric is as follows:
[0021] Firstly, the raw yarn of weft yarn CU100D / 60F is twisted, and the twist is increased to 760TPM. Choose a frustum-shaped plastic bobbin with holes on the surface, a bottom angle of 86°, and a weight of 140g, and wrap it with 40S / 2 polyester semi-bleached yarn, with a wrapping weight of 100g, and wrap it for later use. Then the cupro filaments that have been twisted are loosened onto the plastic bobbins that are coated with polyester semi-bleached yarns, and the loose yarn density of the twisted cupro filame...
Embodiment 2
[0025] Example 2: Processing of khaki cupro ammonia filament yarn-dyed high-grade fabric with the specification of CPT100 / 2*CU100D / 60F+DL40+40D (1:1) 140*110.
[0026]In the fabric specifications of Example 2, CPT100 / 2 refers to compact spinning pure cotton 100 lbs, CU100D / 60F refers to cupro ammonia yarn with a yarn count of 100D and a hole number of 60F, and DL40+40D refers to cotton-wrapped spandex yarn , That is, 40 English count cotton core 40D spandex, the fabric composition is: 74% cotton, 23% cupro ammonia fiber, 3% spandex. The processing process of the fabric is as follows:
[0027] Firstly, the raw yarn of weft yarn CU100D / 60F is twisted, and the twist is increased to 800TPM. Choose a frustum-shaped plastic bobbin with holes on the surface, a bottom angle of 85°, and a weight of 140g, and wrap it with 60S / 3 polyester semi-bleached yarn, with a wrapping weight of 120g, and set it aside after wrapping. Then the cupro filaments that have been twisted are loosened ont...
