Abstract

The invention relates to the field of modified polypropylene fibers, in particular to an antibacterial polypropylene fiber and a preparation method. In the present invention, graphene oxide and mercaptoethylamine are reacted to obtain mercapto-modified graphene oxide; the product after mercapto-ene click chemical reaction of mercapto-modified graphene oxide and octavinyl POSS continues to react with alkyl mercaptan, and then React with N,N-diethyl-4-mercaptobutylamine, and the obtained product is subjected to a quaternization reaction with a halogenated organic quaternization reagent to obtain a quaternized POSS / graphene composite material. The quaternized POSS / graphene composite material is granulated with polypropylene particles to obtain modified polypropylene particles, and then melt-spun with polypropylene particles to obtain antibacterial polypropylene fibers. The antibacterial polypropylene fiber of the present invention has good antibacterial properties, electrical conductivity, heat resistance and flame retardancy, and can be spun alone or blended with other fibers to form, thereby broadening the application range of the fabric.

Description

technical field [0001] The invention relates to the field of modified polypropylene fibers, in particular to an antibacterial polypropylene fiber and a preparation method. Background technique [0002] Polypropylene fiber is a synthetic fiber spun from isotactic polypropylene obtained by propylene polymerization. It has the characteristics of light weight, high strength, good elasticity, wear resistance and corrosion resistance, but poor heat resistance, aging resistance, Insufficient electrical insulation limits its application in some special occasions. [0003] Cage polysilsesquioxane, referred to as POSS, has a general structural formula (RSiO 1.5 ) n , is an inorganic core composed of silicon-oxygen skeletons connected alternately by Si-O, and the group R connected to the Si atom at its vertex is a reactive or inert group. The three-dimensional size of POSS is between 1.3nm, the distance between Si atoms is 0.5nm, and the distance between R groups is 1.5nm, which bel...
