ABSTRACT:
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.
