Preparation method of long-acting and anti-bacterial polylactic acid fiber film

Abstract

The invention discloses a preparation method of a long-acting and anti-bacterial polylactic acid fiber film, belonging to the technical field of eco-friendly material. The method comprises the following steps: mixing polyethylene glycol with dichloromethane according to the volume ratio ranging from 2:7 to 2:8 into a stirring machine, adding anti-bacterial additive which is 0.1 to 0.3 times the volume of the polyethylene glycol and polylactic acid which is 1.0-1.4 times the volume of the polyethylene glycol, mixing the above for 30-60 minutes and keeping stirring at temperature ranging from 40-50 DEG C and at rotary speed ranging from 380 to 500r/min and carrying out ultrasonic dispersion operation on the mixture at the frequency being 45 to 55 kHz in order to acquire spinning liquid; performing electrostatic spinning on the spinning liquid in order to obtain a film so that the long-acting and anti-bacterial polylactic acid fiber film is acquired. According to the technical scheme, thelong-acting and anti-bacterial polylactic acid fiber film enjoys excellent advantages such as anti-bacterial performance and long-acting and anti-bacterial performance so that a broad prospect in theindustry of eco-friendly material is acquired. A ceramic grinding aid prepared by the technical scheme has the feature of excellent grinding aiding efficiency and has a wide prospect in the development of the industry for ceramic processing agents.

Description

technical field [0001] The invention discloses a preparation method of a long-acting antibacterial polylactic acid fiber membrane, which belongs to the technical field of environmental protection materials. Background technique [0002] Polylactic acid fiber is made of corn, wheat, sugar beet and other starchy agricultural products, which are fermented to produce lactic acid, and then made by polycondensation and melt spinning. Polylactic acid fiber is a kind of raw material that can be planted and is easy to plant. Synthetic fibers that naturally degrade in nature. It can be decomposed into carbon dioxide and water by microorganisms in soil or seawater. When burned, it will not emit poisonous gas and cause pollution. It is a sustainable ecological fiber. The fabric has good handle and drapability, anti-ultraviolet radiation, low flammability and excellent processing performance. It is suitable for various fashion, casual wear, sporting goods and sanitary products, etc., an...
