Problems solved by technology

Although the waterproof swimsuit fabric using C8 structure fluorine-containing chemicals can achieve a waterproof effect of more than 90 points, it is an organic chemical pollutant that is difficult to degrade
Among them, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) are the most widely used and most representative substances, but studies have shown that both substances can cause cancer in humans

Abstract

The invention provides a process for preparing an environment-friendly waterproof swimming suit fabric. The process comprises the following steps: blending a waterproof treatment solution, and locking a C6 type fluorocarbon compound on the surface of a fabric by utilizing the effect of a high-efficiency cross-linking agent, so that the swimming suit has a lasting waterproof effect. Due to the detection, the waterproof effect can reach 90 scores or higher, the waterproof effect with the C6 type fluorocarbon compound does not have any obvious difference from that with a perfluorinated compound of a C8 structure, and the defect that the existing swimming suit fabric is harmful to the environment and human body is overcome on premise of meeting the requirements of customers on water prevention of the swimming suit.

Description

technical field [0001] The invention relates to a waterproof swimsuit fabric and its preparation process, in particular to an environment-friendly waterproof swimsuit fabric and its preparation process. Background technique [0002] Waterproof technology is applied to swimsuits to better reflect the swimming posture, and even to quickly dry the worn swimsuits after leaving the water bath, which is one of the needs of swimmers and enthusiasts. However, chemical substances perfluorinated compounds (PFCs), which are harmful to health and the environment, have been detected in more than half of the swimsuits on the market, many of which are internationally renowned brands. According to the explanation of Oeko-Tex Standard 100: perfluorinated compounds with C8 structure are a kind of fluorine-containing chemicals with special characteristics, which can make materials oil-proof, stain-proof and water-proof. Although the waterproof swimsuit fabric using C8 structure fluorine-conta...
