AI Technical Summary

Technical Problem

Existing flash-spun nonwoven fabrics have difficulty maintaining high strength and protective performance while achieving a soft feel and leather-like texture during the texturing process. Traditional texturing processes may damage the material or have insignificant effects.

Method used

A meltblown polypropylene fiber layer is laminated onto the surface of flash-spun nonwoven fabric and treated with a gradient texturing process, including low-temperature pretreatment, high-temperature deep treatment and cooling setting, combined with impregnation and cleaning with polydimethylsiloxane alcohol of a specific molecular weight to form a three-dimensional texture.

Benefits of technology

It improves the softness and mechanical strength of nonwoven fabrics, maintains a waterproof performance of over 90%, and has excellent overall performance.
