Abstract: A yarn disclosed that is formed of a blend of polyester fibers customized by three parameters (1) a combination of polyester staple fibers with staple lengths of 1.5 inches, 1.25 inches, 1.0 inch and 0.75 inch; (2) a combination of polyester staple fibers with staple deniers (tex, fineness) of 1.0 dpf, 1.2 dpf, and 1.5 dpf; and (3) a combination of polyester staple fibers with at least two different staple cross sections.

Abstract: A copolymer composition is disclosed with advantages for textile fibers, yarns, blended yarns, fabrics, and garments. The composition includes polyester copolymer, between about 4.5 and 5.5 percent adipic acid based on the amount of copolymer, between about 630 and 770 parts per million (ppm) of pentaerythritol based on the amount of copolymer, and between about 3.4 and 4.2 percent polyethylene glycol based on the amount of copolymer.

Abstract: A dyed blended yarn is disclosed that includes cotton fibers, polyester fibers, and a dye selected from the group consisting of direct dyes and reactive dyes. The polyester fibers consist essentially of between about 9 and 16 mole percent of DEG based on the amount of polyester, between about 3.5 and 7 mole percent of adipic acid based on the amount of polyester, and between about 200 and 2000 ppm by weight pentaerythritol based on the amount of polyester. The blended yarn includes a dye selected from the group consisting of direct dyes and reactive dyes.

Abstract: A spun yarn includes a bicomponent staple fiber comprising poly(trimethylene terephthalate) and cotton staple fiber, where the poly(trimethylene terephthalate) is present at a level of at least 1 wt % and less than 20 wt % based on total weight of the spun yarn.

Abstract: A process for producing an IPA/PET copolymer fiber that is homogenous having a substantially level, single IPA copolymer content, said fiber having improved pilling resistance and dye uptake.

Abstract: A textile cushioning batting for use in furniture and the like having a high degree of loft and rebound is disclosed comprising: a non-woven blended batting comprising a major portion of a fine denier fiber and a minor portion of a coarse denier fiber. The fibers have increased crimping amplitudes, secondary crimping, sharper crimp and optimized crimps per inch. A low melt binds fiber binding the fine and coarse denier fibers together in the batting; and a sufficient number of the fibers being heat are bonded together at their intersections to provide a high loft resilient batting for cushioning.

Abstract: A method is disclosed for spinning polyester staple to produce dark dyeing yarns as compared to yarns having an otherwise similar composition. The method includes spinning polyester staple into yarn, in which the polyester includes between about 0.5 and 4 percent by weight of polyethylene glycol, into yarn in a rotor spinning machine at a rotor speed of between about 110,000 and 120,000 rpm and at a tension of between about 2.5 and 3.2 grams/tex. A resulting polyester fiber is also disclosed of between about 1.2 and 2.25 denier per filament, and that contains between about 0.5 and 4 percent by weight of polyethylene glycol, and with a fiber tenacity of 4.7 grams per denier or less.
