Patent number: 11359311Abstract: A method and a system disclosed include drawing each of multiple synthetic yarns from a corresponding supply package to form an oriented yarn. Filaments within the oriented yarn are twisted and detwisted to provide texture thereto, to provide a low stability interlacing during weaving, and to intermingle the filaments, and a uniform air pressure is applied to the oriented yarn to provide a counter-twist. Also, a multi-pick yarn package is formed based on winding all formed oriented yarns, which serve as weft yarns forming adjacent substantially parallel yarns wound together, onto a spool. These weft yarns are simultaneously inserted in a single pick insertion event of a loom apparatus, and conveyed across a warp shed of the loom apparatus through a set of warp yarns. The set of warp yarns and the conveyed weft yarns are interlaced to produce an incremental length of a woven textile fabric.Type: GrantFiled: September 21, 2020Date of Patent: June 14, 2022Inventor: Arun Agarwal
