AI Technical Summary

Technical Problem

Existing polyethylene fibers are difficult to modify into multiple functions such as stain resistance and flame retardancy while maintaining waterproof performance. Traditional methods have problems such as easy loss of antibacterial agents, poor washability, or hardening of the hand.

Method used

Modified polyethylene was prepared by introducing allylphosphonic dichloride into polyethylene and reacting it with p-aminodiphenylamine. Antibacterial nanoparticles were prepared by reacting nano-titanium dioxide modified with epoxybutyltrimethoxysilane with 3,3'-diamino-2,2'-bipyridine and copper ions. Nitrogen-boron flame retardant was prepared by combining cyanuric chloride with β-(3-aminopropyl)boric acid. Waterproof and stain-resistant fibers were prepared by using a melt spinning machine.

Benefits of technology

It achieves a synergistic improvement in the waterproof, stain-resistant, flame-retardant, and antibacterial properties of polyethylene fibers, and has good durability and multi-functionality, while improving the flame-retardant and UV-resistant properties of the fibers.

Abstract

The application relates to a waterproof and antifouling fabric and a preparation method thereof, and relates to the technical field of fibers.In the preparation of the waterproof and antifouling fabric, allyl phosphinic dichloride is introduced into polyethylene and reacts with p-aminodiphenylamine to obtain modified polyethylene; antibacterial nanoparticles are prepared by first modifying the surface of nano-titanium dioxide with epoxy butyl trimethoxysilane, and then sequentially reacting with 3,3'-diamino-2,2'-bipyridine and copper ions; and a nitrogen-boron flame retardant is prepared by reacting cyanuric chloride with B-(3-aminopropyl) boronic acid.Modified polyethylene, antibacterial nanoparticles and the nitrogen-boron flame retardant are spun through a melt spinning machine to prepare waterproof and antifouling fibers, and the waterproof and antifouling fibers are woven into a waterproof and antifouling fabric.The prepared fibers have good mechanical properties and durability, and have antibacterial and flame-retardant properties, and can be widely applied to the field of functional textiles.
