  • Patent number: 7188462
    Abstract: A process for making a high-strength spun yarn begins by feeding one or more tows of substantially uncrimped continuous filaments of high-modulus material having a tensile modulus exceeding about 20×106 psi through a high-speed stretch-breaking apparatus operating at low total draft ratio (preferably about 2.0) to break the filaments into high-modulus staple fibers having an average length in the range of about 5 to 6 inches. The tows advantageously are heavy, for example, having a denier of about 25,000 to about 500,000. Following the stretch-breaking step, the staple fibers are collected in sliver cans, and the staple fibers are advanced from the sliver cans to a spinning machine, where the fibers are spun into yarn. An important aspect of the invention is that no intermediate processes are performed between the stretch-breaking and spinning processes, which minimizes disruption of the alignment of and damage to the staple fibers.

  • Patent number: 7127879
    Abstract: A ply-twisted yarn useful in cut resistant fabrics is made by providing a first multifilament yarn of continuous organic filaments having a tensile strength of at least 4 grams per denier and having a twist in a first direction of from 0.5 to 10 turns per inch; providing a second yarn comprising 1 to 5 continuous inorganic filament(s); and ply-twisting the first yarn and the second yarn about each other 2 to 15 turns per inch in a second direction opposite to that of the twist in the first yarn to form a ply-twisted yarn having an overall effective twist of +/?5 turns per inch.

  • Patent number: 7089725
    Abstract: An article of furniture is made from elongated polymer filaments. The polymer filaments may be monofilaments or plural filaments which are twisted together and heat set to prevent their untwisting during the subsequent weaving process. The heat setting of the polymer filaments is achieved by heating the polymer material either before or after the twisting process.

  • Publication number: 20040131821
    Abstract: Towels which produce little to no lint (herein referred to as “lint-free”) and methods for making such towels are described herein. The lint-free towels contain a small amount of short cotton fibers in the pile yarn and the pile yarn contains a low twist factor. In the preferred embodiment, 24% or more of the noil is removed when the pile yarn is produced. This combination of low twist factor with few short cotton yarn, results in soft, absorbent, lint-free towels. Preferably, the lint-free towels contain yarn with a hairiness index of 5 to 7.5. The lint-free towels are produced by twisting the pile yarn with a poly vinyl alcohol (PVA) spun yarn. After weaving the yarns to form a towel, the PVA yarn is then dissolved during the production process, leaving twistless pile yarn.
