Abstract

The invention discloses an antibacterial and antifouling composite fabric and a processing technology thereof. The antibacterial and antifouling composite fabric comprises an inner layer and an outer layer; the inner layer is obtained by finishing a polyester-covered cotton blended fabric with a silk peptide finishing agent; the outer layer is a polyester fabric with surface flock; the finishing agent is prepared from the following components of double-end epoxy carbonyl polysiloxane, diethylenetriamine, toluene diisocynate, polyester polyol, polyethylene glycol, 1,4-butanediol, dimethylolbutyric acid and silk peptide; and the flock is prepared from the following components of polyester diol, diphenylmethane-4,4-diisocyanate, di(3-trimethoxysilyl propyl)amine, styrene and trivinyl trimethyl cyclotrisiloxane. The polyester-covered cotton blended fabric and the polyester fabric are treated with the finishing agent and short fibers respectively to sequentially obtain an inner-layer fabric and an outer-layer fabric; and by arranging the finishing agent, the short fiber component and the preparation process thereof, the antibacterial ability of the inner-layer fabric is improved, and the antifouling ability of the outer-layer fabric is improved.

Description

technical field [0001] The invention relates to the technical field of composite fabrics, in particular to an antibacterial and antifouling composite fabric and its processing technology. Background technique [0002] We refer to new materials that are pasted and bonded with one or more layers of textile materials, non-woven materials and other functional materials as composite fabrics; in the field of traditional school uniform fabrics, composite fabrics are rarely used, and commonly used fabrics are polyester, polyester Cotton blended fabric has better elasticity and drapability, and is not easy to wrinkle, but it has poor resistance to dirt and is easy to breed bacteria. Therefore, we propose an antibacterial and antifouling composite fabric and its processing technology. Contents of the invention [0003] The purpose of the present invention is to provide an antibacterial and antifouling composite fabric and its processing technology, so as to solve the problems raise...
