Problems solved by technology

However, in this structure, a large number of short and thin fibers are used. When the fibers are welded to each other, it is easy to cause openings in the melt-blown non-woven fabric layer of the multi-layer non-woven fabric, resulting in a decrease in the water resistance of the non-woven fabric itself.
This defect can be adjusted by adjusting the welding temperature during welding, so that the melt-blown non-woven fabric layer is combined tightly without opening holes, but at the same time, it will also lead to a decrease in the bonding force between the non-woven fabrics, and the strength of the non-woven fabric will decrease significantly.

Abstract

The invention provides an anti-siphon multi-layer non-woven fabric. The anti-siphon multi-layer non-woven fabric is prepared from, by weight, 30%-70% of polyester fibers and 30-70% of low-melt cotton,wherein the diameter of the polyester fibers is 1.5-15 micrometers, the length of the polyester fibers is 51-56 millimeters, the diameter of the low-melt cotton is 2-4 micrometers and the length of the low-melt cotton is 51-56 millimeters. By selecting coarse and long fibers, the water resistance, fluffiness and tearing performance of the nonwoven fabric can be enhanced; at the same time, short and fine fibers are reasonably proportioned, so that the nonwoven fabric obtains good water resistance and tearing performance after the laminate is combed. In the selection of the raw materials of thenon-woven fabric, it is found that the length and thickness of the fibers have decisive influence on the final performance of the non-woven fabric, and the fibers with different thicknesses and lengths are optimally proportioned to obtain the anti-siphon multilayer non-woven product.

Description

technical field [0001] The invention relates to the technical field of textile materials, in particular to an anti-siphon multi-layer non-woven fabric, especially in the field of outdoor products, which has outstanding improvement effects. Background technique [0002] Along with the raising of people's living standard, outdoor exercise is more and more subject to liking of people as a kind of healthy exercise way. When doing outdoor sports, you generally need to carry some necessary outdoor equipment products. For example, outdoor tents and outdoor shoes are the more commonly used outdoor equipment products. Outdoor equipment products have higher requirements for waterproof, wear-resistant, and tear-resistant performance. In the prior art, the auxiliary materials of outdoor equipment products such as outdoor tents and outdoor shoes are generally made of ordinary non-woven fabrics or cardboard. The performance is poor and cannot meet the needs of outdoor equipment products....
