Problems solved by technology

If the polypropylene fiber is used for a long time in a relatively humid environment, it is easy to breed fungi, so antibacterial polypropylene fiber has been developed. Half of the technical route for producing antibacterial polypropylene fiber in the prior art is to add antibacterial agents to polypropylene. Then carry out follow-up procedures such as melt blending, casting, pelletizing and packaging. This process has many shortcomings, that is, the process is long, the melting process consumes a lot of power, wastes energy, low production efficiency, and large investment in equipment. Defects such as many people, high cost, poor surface transfer effect of antibacterial agents, insufficient long-lasting antibacterial and water-resistant properties, resulting in inability to exert antibacterial effects, etc.

Abstract

The invention relates to a method for producing anti-bacterial polypropylene. The method for producing anti-bacterial polypropylene comprises the following steps: (1) adding polypropylene and polyamide into a reaction kettle provided with a high-speed stirrer for stirring to obtain a mixture of polypropylene and polyamide; (2) uniformly mixing an anti-bacterial agent and a coupling agent; and (3) heating the mixture obtained in the step (1) to 80-95 DEG C, slowly adding the anti-bacterial agent and the coupling agent which are mixed uniformly in the step (2) into the mixture of polypropylene and polyamide obtained in the step (1) to allow the anti-bacterial agent and the coupling agent to uniformly permeate into the mixture, continually stirring for 20-30 minutes, reacting, removing from the reaction kettle, and spinning. By adopting the anti-bacterial polypropylene produced according to the method, the anti-bacterial performance of polypropylene fiber can be improved. Moreover, the method has low requirement on equipment, the process flow and production time are shortened, the labor efficiency is increased, the labor cost is reduced, the production cost is reduced, and the energy consumption is lowered.

Description

technical field [0001] The invention relates to the production of a fiber in the field of material chemistry, in particular to a production method of antibacterial polypropylene. Background technique [0002] Polypropylene (PP) is a thermoplastic resin obtained by polymerizing propylene. Polypropylene fibers can be seen everywhere in real life and have a wide range of uses. If the polypropylene fiber is used for a long time in a relatively humid environment, it is easy to breed fungi, so antibacterial polypropylene fiber has been developed. Half of the technical route for producing antibacterial polypropylene fiber in the prior art is to add antibacterial agents to polypropylene. Then carry out follow-up procedures such as melt blending, casting strips, pelletizing, and packaging. This process has many shortcomings, that is, the process is long, the melting process consumes a lot of power, wastes energy, production efficiency is low, and equipment investment is large. Many...
