Sewing thread and its manufacture

Abstract

A method of manufacturing textured thread textured thread comprises the steps of: processing textured yarn having a zero or near-zero twist by applying a singles twist thereto; plying at least two textured yarns together by twisting them in a direction opposing the singles twist; wherein the singles twists lie in the range 4 to 20 turns per inch and the plying twist lies in the range 2 to 18 turns per inch.

1 . A method of manufacturing textured thread textured thread comprising the steps of:
 processing textured yarn having a zero or near-zero twist by applying a singles twist thereto;   plying at least two textured yarns together by twisting them in a direction opposing the singles twist;   wherein the singles twists lie in the range 4 to 20 turns per inch and the plying twist lies in the range 2 to 18 turns per inch.   
     
     
         2 . A method according to  claim 1  wherein the textured yarn is produced with a false twist. 
     
     
         3 . A method according to  claim 1  wherein the textured yarn is produced by the application of pressured air. 
     
     
         4 . A method according to  claim 1  wherein the textured yarn is processed at a speed which is lower than for standard continuous filament thread of the same weight. 
     
     
         5 . A method according to  claim 4  wherein, for thread weights of between 18 and 120 Tex, the textured yarn is processed at between 82 and 95% of the speed at which continuous filament yarns of the same weight are processed. 
     
     
         6 . A method according to  claim 4  wherein the textured yarn is processed at a tension which is lower than for standard continuous filament yarns of the same weight. 
     
     
         7 . A method according to  claim 6  wherein, for thread weights of between 18 and 70 Tex, the plying step takes place at a tension of between 65% and 40% of the tension for continuous filament thread of the same weight. 
     
     
         8 . A textured thread comprising a plurality of textured yarns plied together, wherein each textured yarn has a twist of 4 to 20 turns per inch and the textured yarns are plied together with an opposing twist of 2 to 18 turns per inch. 
     
     
         9 . A textured thread according to  claim 8  wherein the textured yarns have a false twist. 
     
     
         10 . A textured thread according to  claim 8  wherein the textured yarns were created by the application of pressured air. 
     
     
         11 . A method of manufacturing apparel comprising the steps of stitching two panels of fabric together using a textured thread comprising a plurality of textured yarns plied together, wherein each textured yarn has a twist of 4 to 20 turns per inch and the textured yarns are plied together with an opposing twist of 2 to 18 turns per inch. 
     
     
         12 . A garment comprising a plurality of panels of fabric, at least two of which are stitched together by a textured thread comprising a plurality of textured yarns plied together, wherein each textured yarn has a twist of 4 to 20 turns per inch and the textured yarns are plied together with an opposing twist of 2 to 18 turns per inch.
