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.
