Abstract

The invention discloses a preparation method of a composite anti-bacterial fiber membrane, and belongs to the field of functional textile materials. A polyacrylonitrile anti-bacterial nano-fiber membrane with efficient anti-bacterial performance is prepared by adding an anti-bacterial agent into polyacrylonitrile and cuprammonia regenerated cellulose through an electrospinning technology. The anti-bacterial agent in the fiber membrane is prepared by polymerizing 2-methyl-2-crylic acid-1,2-propylene glycol, dimethylaminoethyl methacrylate, allyltriethoxysilane, hectorite and nano titanium oxide. The preparation method comprises the following steps: adding the anti-bacterial agent, nano-silver, copper-zeolite molecular sieve micro powder and nano zinc oxide sol into a mixed solution of the polyacrylonitrile and the cuprammonia regenerated cellulose, and uniformly mixing the materials; performing electrostatic spinning to obtain a fiber membrane; soaking the fiber membrane into a brominechloride solution; taking the fiber membrane out and drying to obtain the composite anti-bacterial fiber membrane. The anti-bacterial nano-fiber membrane can be applied to the fields of daily use, textile, industry and medicine.

Description

technical field [0001] The invention relates to the technical field of functional textile materials, in particular to a preparation method of a composite antibacterial fiber membrane. Background technique [0002] Nanofibrous membrane has the advantages of large surface area, high porosity, loose structure, pre-designed composition according to the required function, simulating extracellular matrix, and simple preparation method, and has great application potential in many fields. It has been used in food, medicine, Daily chemicals and other fields have been widely used. In particular, nanofibrous membranes prepared with natural polymers as spinning solutions not only have the above characteristics, but also have excellent biocompatibility, biodegradability and renewability. [0003] The silver-loaded nanoparticle / composite fiber membrane prepared by the prior art has poor biocompatibility, and by-products are produced during the preparation process, which causes the struct...
