WORLD'S FIRST: DOWNPROOF COTTON FABRIC
DOWNPROOF-WINDPROOF FABRIC



Taiwan Downproof Fabric & Windproof Fabric Manufacturer - HerMin Textile
The world's first biodegradable downproof fabric - Downproof Cotton Fabric.
Unlike traditional downproof fabrics that are made from polyester or nylon, HerMin's downproof cotton fabric is made from 100% cotton. Using super long staple fiber and really condensed weave, we have created a cotton fabric that is truly downproof, windproof, membrane, and lamination-free.
This feather proof fabric can pass IDFL-20 downproof standards, and be treated with PFC-free water repellent. Our intention for this creation is to make functional fabrics more sustainable and focus on fabrics that can truly biodegrade. For brands that strive for extra sustainability, we also offer GOTS 5.0 standard with organic cotton version and BCI cotton upon request.
