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

Abstract

The finishing method of durable flame-retardant, moisture-permeable, single-suction and single-proof fabrics of the present invention is characterized in that (1) hot-rolling the front of aramid fibers and their blended fabrics, (2) using 1.7-2 parts of polyacrylic acid thickener , 6 parts of toluene, 80-77 parts of water, 10-12 parts of fluorine-free waterproofing agent with hydrocarbon polymer structure, 2-2.5 parts of blocked isocyanate synergist, 0.3-0.4 parts of polyurethane associative thickening and leveling agent The obtained waterproof coating glue coats the front of the fabric, (3) with 1.7-2 parts of polyacrylic acid thickener, 6 parts of toluene, 87-84 parts of water, 5-7 parts of polyurethane hydrophilic finishing agent, polyurethane The hygroscopic coating glue prepared by associative thickening and leveling agent 0.3-0.4 parts is used to coat the reverse side of the fabric; the finished fabric has excellent flame retardancy and moisture permeability, and has one-sided waterproof and one-sided moisture absorption speed Dry and washable, breathable and soft, comfortable to wear, easy 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 ...
