Finishing method of durable flame-retardant, moisture-permeable, single-absorption and single-sided waterproof fabric

Abstract

The invention discloses a finishing method of a durable flame-retardant, moisture-permeable, single-absorption and single-sided waterproof fabric. The finishing method is characterized by comprising the following steps of (1) carrying out hot rolling on the front surfaces of aramid fibers and blended fabrics thereof; (2) carrying out coating treatment on the front surface of the fabric by using a waterproof coating adhesive prepared from 1.7-2 parts of a polyacrylic acid thickener, 6 parts of methylbenzene, 77-80 parts of water, 10-12 parts of a hydrocarbon polymer structure fluoride-free waterproof agent, 2-2.5 parts of a blocked isocyanate synergist and 0.3-0.4 part of a polyurethane associative thickening leveling agent, and (3) performing coating treatment on the back surface of the fabric by using a moisture absorption coating adhesive prepared from 1.7-2 parts of a polyacrylic acid thickener, 6 parts of methylbenzene, 84-87 parts of water, 5-7 parts of a polyurethane hydrophilic finishing agent and 0.3-0.4 part of a polyurethane associative thickening leveling agent. The finished fabric has excellent flame retardancy and moisture penetrability, has single-sided waterproofness and single-sided moisture absorption quick-drying property, and is good in washability, breathable, soft, comfortable to wear and convenient to produce and operate.

Description

technical field [0001] The invention relates to fabric finishing technology, which belongs to textile functional finishing technology. The fabric after finishing has excellent flame retardancy and moisture permeability, and has single-absorption (moisture absorption and quick-drying on one side) function and single-proof (one-side waterproof) function. , and good washability, breathable, soft, comfortable to take. Background technique [0002] General-purpose protective clothing fabrics need to have sufficient tensile strength, tear resistance, abrasion resistance, weather resistance, moisture absorption and quick-drying, softness and other functions, and special protective clothing fabrics must also be waterproof or flame-retardant, Antistatic, anti-radiation and other functions to meet the needs of special industries. [0003] Water repellency is the characteristic of fabrics that are not easily wetted by water. The surface of the fiber is hydrophobic; however, it cannot ...

AI Technical Summary

Problems solved by technology

This invention improves the single function of the existing fabric, so that it has a certain effect of internal absorption and external defense, but the performance index that can be achieved is not mentioned in the article

The soaking time of this process is long and the production efficiency is low, and because the hydrophilic finishing is done first, the fabric will have strong water absorption, which will affect the waterproof effect of one side, and the two functions will interfere with each other.

[0008] Patent CN200710023692.1 discloses a "Special Protective Clothing for Flame Retardant Moisture Absorption and Perspiration and Strong Acid and Alkali Resistance". Anti-acid and alkali finishing, because the anti-acid and alkali finishing has strong water repellency, it is coated on the surface of the fiber, so the moisture absorption function of the inner layer will be significantly reduced
