Abstract
The proliferation of the thread count of a woven textile is accomplished through simultaneous insertion, within a single pick insertion event of a loom apparatus, of multiple adjacent parallel yarns drawn from a multi-pick yarn package. In one or more embodiments, multiple texturized polyester weft yarns of denier between 15 and 50 are wound on a single bobbin in a parallel adjacent fashion such that they may be fed into an air jet pick insertion apparatus of an air jet loom to weave a textile that has between 90 to 235 ends per inch cotton warp yarns and between 100 and 765 polyester weft yarns.
Claims19
A woven textile fabric comprising:
- from 90 to 235 ends per inch warp yarns;
- and
- from 100 to 765 picks per inch multi-filament polyester weft yarns;
- wherein the picks are woven into the textile fabric in groups of at least two multi-filament polyester weft yarns running parallel to each other,
- wherein the multi-filament polyester weft yarns are wound substantially parallel to one another and substantially adjacent to one another on a multi-pick yarn package to enable the simultaneous inserting of the multi-filament polyester weft yarns during a single pick insertion event of a pick insertion apparatus of a loom apparatus,
- wherein the number of the multi-filament polyester weft yarns wound substantially parallel to one another and substantially adjacent to one another on the weft yarn package is two,
- wherein the number of the multi-filament polyester weft yarns conveyed by the pick insertion apparatus across a warp shed of the loom apparatus through a set of warp yarns in the single pick insertion event of the pick insertion apparatus of the loom apparatus is between two and eight,
- wherein the pick insertion apparatus of the loom apparatus is an air jet pick insertion apparatus,
- wherein the multi-filament polyester weft yarns are wound on the multi-pick yarn package at an angle of between 15 and 20 degrees to enable the simultaneous inserting of the multi-filament polyester weft yarns during the single pick insertion event of the pick insertion apparatus of the loom apparatus, and
- wherein the multi-filament polyester weft yarns are wound on the multi-pick yarn package at a type a shore hardness of between 65 to 70 to enable the simultaneous inserting of the multi-filament polyester weft yarns during the single pick insertion event of the pick insertion apparatus of the loom apparatus.
