Downproof fabrics are mainly intended for making down garments and down quilts.
Downproof fabrics are characterized with solid and compact texture, low permeability and high performance in preventing down from coming out of down garment.
In most cases, downproof fabrics are woven with combed cotton yarns and mostly in plain texture or in the heavy-duty weave of double ends on the warp side and single on the weft.
