No Sweat Marks Fabric with Moisture Management Function

Abstract

Examples of a knitted or woven fabric with moisture management function are described, comprising a face fabric layer with a durable water repellency (DWR) additives forming a fabric outer surface that is hydrophobic and a back fabric layer comprising a second yarn that is highly hydrophilic forming a moisture regain core to absorb the moisture and spread it across on an inside surface of the back fabric layer. The outer (face) layer of the fabric is hydrophobic due to the added DWR additives to the first yarn while the inner (back) layer of the fabric is highly hydrophilic that absorbs and spreads the moisture across the inner side of the back layer so that it dries faster making the outer surface of the face fabric layer dry thus reducing the occurrence of water I liquid spots on the face layer outer surface.
