[0042] Example 1:
[0043] A preparation process of a novel non-woven fabric based on ultra-high molecular weight polyethylene film includes the following steps:
[0044] (1) Material preparation: According to production requirements, prepare ultra-high molecular weight polyethylene film according to the quantity;
[0045] (2) Laying: stack the ultra-high molecular weight polyethylene film as required;
[0046] (3) Needle punching: Needle punching the ultra-high molecular weight polyethylene film stacked in step (1) with a needle with a triangular cross section and barbed edges. The needling of the ultra-high molecular weight polyethylene film The density is 50 needles / square centimeter to form ultra-high molecular weight polyethylene fiber yarn. The ultra-high molecular weight polyethylene fiber yarn has a fineness range of 0.5 dtex and a strength range of 25 cN / dtex. Continue needle punching. The needle punch density of the silk is 100 needles / square centimeter. When several needle...
