100% Polyester Down-Proof Lining Fabric — Feather Leakage Control

This down proof lining fabric is manufactured from 100% polyester using a tightly woven plain weave structure, specifically engineered for down jackets, padded coats, and insulated outerwear. The fabric undergoes a calendering (glazing) finishing process, creating a compact surface that effectively prevents feather penetration and down leakage. Designed for autumn and winter applications, it serves as a reliable inner lining material for high-performance cold-weather garments.

The smooth, refined handfeel ensures easy garment assembly and wearer comfort, while the dense weave structure delivers excellent feather containment performance. The calendered surface enhances anti-drilling properties, minimizing fiber migration even after repeated wear and washing. This lining fabric offers stable dimensional control, low shrinkage rates, and consistent colorfastness, making it suitable for mass production. Polyester fiber composition provides strength, abrasion resistance, and long-term durability without compromising lightweight comfort.

This fabric is widely used as inner lining for down jackets, padded coats, parkas, winter overcoats, and insulated outerwear. It is also suitable for quilted garments, thermal vests, and cold-weather uniforms where feather control and lining stability are critical performance requirements.

With stable quality control, reliable bulk supply, and factory-direct manufacturing, this down proof lining fabric is ideal for OEM/ODM programs and large-scale garment production. It provides brands, wholesalers, and factories with a dependable solution for premium down-filled apparel requiring consistent anti-feather performance.
