AI Technical Summary

Technical Problem

The existing nylon fabrics have poor performance in antistatic and fast drying properties, and have insufficient mechanical strength, resulting in a reduced use value.

Method used

A multi-layer composite structure of modified graphene, carbon bead layer and hygroscopic layer is adopted. The modified layer is made of bio-based nylon and modified graphene. The carbon bead layer is composed of carbon powder, phenolic resin and nanosilver. The hygroscopic layer is soaked in bio-based nylon and blended into a yarn. It improves mechanical properties through hydrogen bonding and enhances hygroscopicity and antibacterial and anti-mold effects.

Benefits of technology

The antistatic properties and quick-drying effect of nylon fabrics are improved, while maintaining high mechanical strength, enhancing the comfort and antibacterial properties of the fabrics, and avoiding the reduction in fracture force caused by the improvement of antistatic properties.

Abstract

The present invention discloses an antistatic and quick-drying multi-layer composite nylon fabric and a preparation method thereof. The antistatic and quick-drying multi-layer composite nylon fabric sequentially includes, from the outside to the inside: a modified layer, a carbon bead layer, and a moisture absorption layer; the modified layer is prepared by mixing bio-based nylon and modified graphene to obtain a modified graphene nylon fabric, and then blending it into yarn and weaving it; the carbon bead layer is prepared from carbon powder, phenolic resin, nano silver, and a surfactant; the moisture absorption layer is prepared by soaking bio-based nylon in a moisture absorbent, blending it into yarn, and weaving it; when polypropylene / modified graphene fiber modifies the existing bio-based nylon, it not only improves the antistatic resistance but also maintains a relatively high mechanical strength as much as possible. The prepared composite fabric has better antistatic, antibacterial, and moisture absorption properties, effectively solving the problem of the decrease in breaking strength and service performance caused by the improvement of antistatic properties.
