AI Technical Summary

Problems solved by technology

However, most of the treatment agents for this type of protective clothing on the market currently use octacarbon fluorine-based waterproofing agents, which contain environmentally harmful substances such as PFOS and PFOA, which have very serious environmental problems.
Moreover, although this type of protective clothing has an anti-adhesion function, it does not have a good washing resistance effect. Often after several washes, the anti-adhesion function loses its effect and cannot continue to provide protection.

Abstract

The invention belongs to the technical field of waterproof and oil-proof agents for textiles, and particularly relates to a hexa-fluorocarbon-series high-washing-resistance waterproof and oil-proof agent and a preparation method thereof. The hexa-fluorocarbon-series high-washing-resistance waterproof and oil-proof agent provided by the invention is prepared from the following raw materials in parts by weight of 50-100 parts of fluororesin emulsion and 30-100 parts of cross-linking agent. The hexa-fluorocarbon-series high-washing-resistance waterproof and oil-proof agent prepared by the invention is used for water and oil resistance of woven fabric, can form a high-water-resistance and oilproof film layer on the surface of the woven fabric, and also has relatively good air permeability; andwhen the fabric is used for woven cloth medical clothes, the waterproof, adhesion-resistant and washing-resistant performance of the medical clothes can be guaranteed, the difficulty of protection work of medical workers in the epidemic situation period is lowered, and the comfort degree of the medical workers is improved.

Description

Technical field [0001] The present invention belongs to the technical field of textile waterproofing, and more particularly to a hexa-carbon fluorine-based high-resistance to washing waterproof oil repellent and a preparation method thereof. Background technique [0002] Due to the special needs of their working environment, medical staff often need to wear various protective clothing, such as daily overalls, surgical clothes, isolation and protective clothing. Among them, it can also be different from the use of materials and processing technology, which is distinguished into a woven medical clothing and nonwoven fabric medical apparel. [0003] Among them, the woven medical apparel material is mostly used to polyester or polyester cotton mixed fabric, which is mainly used in reusable medical clothing, such as daily overalls and surgical efforts, which have better wear comfort, but this The cost of the apparel material is poor, the blood, medicament, etc. are easily adhered to t...
