eptfe membrane used in functional fabrics
Huzhou Kaili New Material Technology Co., Ltd. specializes in the processing, finishing, and customization of ePTFE membranes used in functional fabrics, serving textile mills, composite fabric manufacturers, and performance apparel brands worldwide. Based in Huzhou, Zhejiang Province-within the Yangtze River Delta fluoromaterial industry cluster-we focus on transforming high-performance fluoropolymer membranes into reliable textile-ready solutions.
This ePTFE membrane is designed as a functional core layer, enabling fabrics to achieve protection, comfort, and durability simultaneously.
Product Definition
The ePTFE membrane used in functional fabrics is an expanded polytetrafluoroethylene film featuring a stable microporous structure. When integrated into woven, knitted, or nonwoven fabrics through lamination or coating, it delivers breathable barrier performance without compromising fabric flexibility or wearability.
The membrane functions as an invisible performance layer, enhancing fabric value while maintaining lightweight construction.
