An integrally fabricated textile fabric has a relatively thick, dense liquid retaining absorbent pile layer of hydrophilic yarns and a non-absorbent napped layer of hydrophobic yarns at opposite faces of the fabric integrated with an intermediate ground yarn structure. The napped hydrophobic yarn layer serves to wick liquid to the absorbent hydrophilic yarn layer while resisting return flow leakage. The fabric is preferably fabricated on a warp knitting machine wherein a set of hydrophilic yarns are warp knitted by the bottom machine guide bar in overfed needle loops at the technical face of the fabric, a set of hydrophobic yarns are warp knitted on the top machine guide bar in needle loops and extended nappable underlaps at the technical back of the fabric, and two sets of ground yarns are warp knitted by a respective pair of middle guide bars intermediate the fabric faces.
An integrally fabricated textile fabric characterized by a liquid permeable non-absorbent layer at one face of said fabric adapted for initial liquid contact in use of said fabric and a liquid retaining absorbent layer at the opposite face of said fabric for wicking of liquid from said non-absorbent layer to, and retention of wicked liquid by, said absorbent layer while maintaining said non-absorbent layer essentially dry to touch, said fabric comprising hydrophobic yarn formed in a raised surface construction predominantly at said one face of said fabric to form said non-absorbent layer, hydrophilic yarn formed in a relatively dense extended pile construction predominantly at said opposite face of said fabric to form said absorbent layer, and generally inelastic ground yarn formed in a dimensionally stable generally non-stretchable construction, each of said hydrophobic, hydrophilic and ground yarns being intermeshed with at least one of the other for integrating said absorbent and non-absorbent layers, said raised surface construction of said hydrophobic yarn in said non-absorbent layer sufficiently covering said ground and hydrophilic yarns with sufficiently small interstices in said non-absorbent layer to permit liquid permeation therethrough to said absorbent layer while serving to resist leakage of absorbed liquid from said absorbent layer through said non-absorbent layer.
