Abstract

The invention discloses a preparation method of a breathable polytetrafluoroethylene film for fabric. The method comprises the steps as follows: S1, adding N,N-dimethylformamide, ethyl acetate, diacetone alcohol, di-n-octyl phthalate and a silane coupling agent to a reactor, and stirring the mixture uniformly; S2, putting sodium carboxymethylcellulose and nano graphene to the reactor, and performing high-speed dispersion; S3, adding polytetrafluoroethylene resin, fluorine-containing polyacrylate, PEEK (polyether-ether-ketone), hydroquinone and chitosan to the reactor, and performing heating and melting; S4, performing blow molding by a film blowing machine. The prepared polytetrafluoroethylene film has high water vapor permeability and can guarantee waterproof property, discharge water vapor formed by sweat on skin surface smoothly through the fabric, prevent bacterium breeding and make wearing experience more comfortable after being applied to clothes fabric.

Description

technical field [0001] The invention relates to the field of polytetrafluoroethylene films, in particular to a method for preparing a polytetrafluoroethylene gas permeable film for fabrics. Background technique [0002] In the current industrial production engineering, electrostatic hazards have become an important factor affecting product quality and production safety, especially in the fields of electronics, printing, film, electronic maintenance, petroleum, chemical industry, dust industry, etc., more and more attention has been paid to the production environment and production safety protection , Anti-static clothing and related anti-static fabric materials are increasingly used in various industries, and with the special requirements of certain industries, the requirements for electrostatic protection are becoming more and more stringent. [0003] The main anti-static clothing and fabrics on the market at this stage mainly achieve the purpose of anti-static by implantin...
