AI Technical Summary

Technical Problem

Traditional mesh fabrics are prone to heat shrinkage and deformation during high-temperature setting processes, and lack abrasion resistance and flexibility, making it difficult to meet the performance requirements of footwear materials and high-end industrial textiles.

Method used

ZFA bicomponent composite monofilament is used as the base fabric layer. Thermoplastic polyurethane is melted at high temperature and bonded to the functional yarn layer to form a stable composite structure. Combined with FDY multifilament with a specific linear density to construct a mesh skeleton, the fabric is ensured to maintain dimensional stability and high stiffness at high temperatures.

Benefits of technology

The fabric exhibits minimal dimensional change at high temperatures and forms a high-stiffness skeleton after cooling, thus solving the problem of heat shrinkage and deformation while maintaining flexibility and abrasion resistance, making it suitable for the high-end fabric needs of various industries.
