Abstract

A woven fabric includes a plurality of warp yarns and a plurality of weft yarns interwoven with the plurality of warp yarns to define the woven fabric. Multiple weft yarns are inserted through the shed during weaving cycle to form higher thread count fabrics.

First claim

What is claimed:

1. A spun staple yarn that is elongated along a length, the spun staple yarn comprising:
a single ply ring spun yarn consisting essentially of an outer sheath of cotton staple fibers that are twisted about a yarn central axis that extends along the length, the single ply yarn defining a first open space that extends along an entirety of the length, and a separate, second open space that extends along the entirety of the length, wherein the first open space and the second open space twist around the yarn central axis and with respect to each other along the entirety of the length of the single ply ring spun yarn,
wherein the outer sheath of cotton staple fibers and the first and second open spaces have the same twist direction,
wherein the single ply ring spun yarn has a yarn cross-sectional dimension that is perpendicular to the yarn central axis,
wherein the first open space and the second open space each define an open space cross-sectional dimension that is perpendicular to the yarn central axis, wherein a combined open space cross-sectional dimension is between 10% to 30% of the yarn cross-sectional dimension,
wherein the single ply ring spun yarn has a count between 8 Ne to 50 Ne,
wherein the single ply ring spun yarn is absorbent, hydrophilic, and adapted for use in home textile articles.

2. The spun staple yarn of claim 1 , wherein the first and second open spaces are formed by dissolving water soluble fibers.

3. The spun staple yarn of claim 2 , wherein the single ply ring spun yarn is formed by the cotton staple fibers and the water soluble fibers having the same twist direction.
