Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
143 words
A textured yarn having a soft luxuriant hand and improved wicking, comprising: a. a first plurality of filaments comprising alternating S-twisted and Z-twisted helically coiled regions connected by twist reversal regions, each of said first plurality of filaments having a cross-sectional area which varies from small values in thin regions to large values in thick regions along its length, said large values being at least 25% greater than said small values, said thick and thin regions being out of phase from filament to filament along the length of said yarn, and b. a second plurality of filaments comprising alternating S-twisted and Z-twisted helically coiled regions connected by twist reversal regions, each of said second plurality of filaments having a cross-section comprising a spiral and wherein the outer portion of said spiral lies at the inside of the coils of said helically coiled regions.
