Embodiment 1
[0055] 1. Hybrid laying:
[0056] The COPET / PA 30 / 70 island-in-the-sea composite fiber, which accounts for 10% of the overall fiber web weight, is mixed with ordinary polyester fiber to lay the net, in which: the upper and lower sides are island-in-sea composite fiber web, and the middle is ordinary polyester fiber web and three layers of polyester base Cloth (0.5×0.5cm grid cloth).
[0057] 2. Acupuncture:
[0058] The acupuncture parameters are:
[0059] Acupuncture equipment 1 2 3、4 5、6 Acupuncture Upper stab Lower stab Upper stab, lower stab Upper stab, lower stab Acupuncture Depth (mm) 11 8 3 4 Acupuncture frequency (times / min) 750 950 670 670 Needle density: 4500 6000 8000 8000
[0060] 3. Fiber opening:
[0061] In this example, COPET / PA 30 / 70 sea-island composite fiber is used, which is composed of COPET and alkali-resistant components, and the COPET content is 3% (accounting for the weight of the whole fibe...
Embodiment 2
[0069] 1. Hybrid laying:
[0070] 20% COPET / PTFE 30 / 70 island-in-the-sea composite fibers accounting for 10% of the overall fiber web weight are mixed with ordinary polyester fibers to lay the web. The upper and lower sides are sea-island composite fiber nets, and the middle is ordinary polyester fiber net and three-layer polyester base cloth (0.5×0.5cm grid cloth).
[0071] 2. Acupuncture:
[0072] The acupuncture parameters are:
[0073] Acupuncture equipment 1 2 3、4 5、6 Acupuncture Upper stab Lower stab Upper stab, lower stab Upper stab, lower stab Acupuncture Depth (mm) 10 9 4 6 Acupuncture frequency (times / min) 770 980 650 650 Needle density: 4500 6000 8000 8000
[0074] 3. Fiber opening:
[0075] In this example, the island-in-the-sea composite fiber is composed of COPET and PTFE, and the COPET content is 6% (accounting for the weight of the whole fiber web), so the amount of caustic soda used for fiber openin...
Embodiment 3
[0082] 1. Hybrid laying:
[0083] The COPET / PPS 30 / 70 island-in-the-sea composite fiber, which accounts for 30% of the overall fiber web weight, is mixed with ordinary polyester fiber to lay the web. The upper and lower sides are sea-island composite fiber nets, and the middle is ordinary polyester fiber net and three-layer polyester base cloth (0.5×0.5cm grid cloth).
[0084] 2. Acupuncture:
[0085] The acupuncture parameters are:
[0086] Acupuncture equipment 1 2 3、4 5、6 Acupuncture Upper stab Lower stab Upper stab, lower stab Upper stab, lower stab Acupuncture Depth (mm) 10 9 4 6 Acupuncture frequency (times / min) 800 1000 700 700 Needle density: 4500 6000 8000 8000
[0087] 3. Fiber opening:
[0088] In this example, the island-in-the-sea composite fiber is composed of COPET and PPS, and the COPET content is 9% (accounting for the weight of the whole fiber web), so the amount of caustic soda used for fiber open...
