preparation example Construction

[0031] The preparation method of above-mentioned anti-tear nonwoven fabric, comprises the steps:

[0032] S1 prepares fiber net: prepare each raw material by weight: low-density polyethylene, hemp fiber, polypropylene, polyisobutylene, softening agent, reinforcing modifier, antistatic agent, lubricant, nano polytetrafluoroethylene, each The raw materials are melted, mixed and loosened, and then combed into a web by a carding machine to obtain a fiber web, and the fiber web is drawn by a drafting machine;

[0033] S2 spunlace: feed the fiber web drawn in step S1 into the spunlace area for the first spunlace and the second spunlace to form a non-woven fabric and dry it;

[0034] S3 cold bleaching: the non-woven fabric dried in the step S2 is immersed in the auxiliary agent and then subjected to cold pile treatment;

[0035] S4 washing: wash the cold-stacked non-woven fabric in step S3 for 2-3 times to remove residual additives;

[0036] S5 drying: put the non-woven fabric wash...

Embodiment 1

[0041] The concrete implementation parameter of embodiment 1-embodiment 6 is as shown in table 1, and wherein embodiment 1-embodiment 4 is the technical parameter that the present invention limits, does not add hemp fiber, nano polytetrafluoroethylene in embodiment 5, embodiment Spunlace was performed only once in 6, and examples 5-6 were comparative examples of the present invention.

Abstract

The invention relates to anti-tearing non-woven fabric and a preparation method thereof, and belongs to the technical field of non-woven fabric and preparation thereof. The anti-tearing non-woven fabric is prepared from, by weight, 50-60 parts of low-density polyethylene, 15-20 parts of fibrilia, 30-40 parts of polypropylene, 20-30 parts of polyisobutene, 5-8 parts of softening agent, 10-15 partsof reinforced modifier, 5-10 parts of antistatic agent, 5-10 parts of lubricating agent and 3-5 parts of nano polytetrafluoroethylene. The preparation method comprises the following steps of fiber webpreparation, wherein raw materials are subjected to fusion, mixing and opening and then are carded by a carding machine to form a web to obtain a fiber web, and a drafting machine carries out drafting on the fiber web; spunlacing, wherein the drafted fiber web is fed into a spunlacing area for primary spunlacing and secondary spunlacing to form the non-woven fabric; drying, cold bleaching, washing and drying. The anti-tearing non-woven fabric and the preparation method thereof have the advantages that the breaking strength is high, the hydrostatic pressure is high, and the molding rate is high.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics and their preparation, in particular to a tear-resistant non-woven fabric and a preparation method thereof. Background technique [0002] Non-woven fabrics are also called non-woven fabrics, non-woven fabrics, non-woven fabrics, and non-woven fabrics. Nonwoven technology is a material processing technology that originates from textiles but surpasses textiles. At present, the main types of non-woven products at home and abroad are: pure cotton non-woven fabrics, polyester / cotton blended non-woven fabrics, viscose / cotton blended non-woven fabrics, polyester / viscose blended non-woven fabrics, wood paddle non-woven fabrics, etc. . [0003] Non-woven products are rich in color, bright and bright, fashionable and environmentally friendly, widely used, beautiful and elegant, with various patterns and styles, and are light in weight, environmentally friendly, and recyclable. They are internati...
