AI Technical Summary

Problems solved by technology

[0008] 1. The strength is low and the tear resistance is average, which cannot meet the requirements of some high-performance guarantee materials;
[0009] 2. If non-woven fabrics made of pure special fibers (or filaments, long fibers) are used, the cost is high and cannot meet market demand

Abstract

The invention discloses a high-strength tear-resistant nonwoven fabric for bag production and a preparation method thereof. The high-strength composite fibers are made from the following raw materials in parts by weight: 30-37 parts of polybutylene adipamide, 45-55 parts of polyhexamethylene adipamide, and 15-55 parts of polysebamide 20 parts, 10-14 parts of poly(p-phenylene terephthalamide), 3.5-5 parts of carboxylated carbon nanotubes, 2.5-3.5 parts of graphene oxide, 1.5-2.2 parts of cerium oxide, 3-5 parts of nano-fillers, 5 to 10 parts of flow aid. Under the condition of the same thickness, the high-strength tear-resistant non-woven fabric for bag production of the present invention has large bursting strength and breaking strength, which are obviously better than ordinary nylon non-woven fabrics, and has high strength and high tear resistance. Excellent performance.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a high-strength tear-resistant non-woven fabric for bag production and a preparation method thereof. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. The non-woven fabric has no warp and weft threads, so it is very convenient to cut and sew, and it is light and easy to shape. [0003] Because it is a fabric that does not require spinning and weaving, it just orients or randomly arranges textile staple fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. [0004] It is not interwoven and braided by yarns one by one, but the fibers are directly bonded together by physical methods, so when you get the sticky scale in your clothes, you will find that, You can't...
