Raw material modification

Copolymerization modification: By choosing different copolymerization monomers to copolymerize with propylene, various functional groups can be introduced to improve the performance of polypropylene yarn. For example, the introduction of monomers containing hydrophilic groups, such as acrylic acid, maleic anhydride, etc., can improve the hygroscopic performance of polypropylene yarn, making it more suitable for clothing and other fields; The introduction of monomer containing flame retardant groups can enhance the flame retardant property of polypropylene yarn and expand its application in fire resistant fabrics.

Grafting modification: The chemical grafting method is used to attach a specific group or molecular chain to the molecular chain of the polypropylene yarn to give it new properties. For example, the molecular chain of anti-ultraviolet absorbent on the graft can effectively improve the light resistance of polypropylene yarn and extend its life in outdoor use; The molecular chain of the grafted antibacterial agent can make the polypropylene yarn have antibacterial function and be used for the production of fabrics in medical and health fields
