Downproof意思

"Downproof" is a term used in the textile and fashion industry, particularly in reference to bedding and clothing. It refers to the ability of a fabric to resist the penetration of down, which is the soft undercoating of feathers found on ducks and geese. Downproof fabrics are designed to keep down in place, preventing it from escaping or poking through the fabric.

Downproof materials are often used in the construction of duvet covers, pillowcases, and other bedding items that are intended to hold down or feathers. They are typically made of tightly woven materials that create a barrier against the down fibers, ensuring that the filling stays inside the duvet or pillow and does not leak out.

In the context of clothing, downproof fabrics are used in garments that are designed to keep the wearer warm by trapping air between the down fibers. Outerwear such as jackets and vests filled with down insulation often have downproof linings to prevent the down from moving around or escaping through the fabric.

Downproof fabrics are usually made of materials like cotton, nylon, or polyester, and they may have a special treatment or coating to enhance their resistance to down penetration. The downproof quality is important for maintaining the longevity and effectiveness of down-filled products, as well as for providing a comfortable and warm sleeping or wearing experience.
