Yarn manufacturing

Abstract

A process for manufacturing a yarn includes twisting the yarn in a first direction for a predefined number of twists. The method also includes, after the predefined number of twists, twisting the yarn in a second direction for a predefined number of twists, the predefined number of twists for the second yarn is same as the predefined number of twists for the first yarn. The twisting of the yarn in the second direction creates an air bed within the yarn's fibers.

1 . A process for manufacturing a yarn, comprising:
 twisting a plurality of fibers in a first direction; and   twisting the plurality of fibers in the second direction, wherein   a change of twisting from the first direction to the second direction or vice versa creates an air gap between the plurality of fibers, and   the air gap is configured to provide the effect of a thicker yarn upon completion of manufacturing.   
     
     
         2 . The process of  claim 1 , wherein the twisting of the plurality of fibers in the first direction is for a predefined number of twists. 
     
     
         3 . The process of  claim 2 , wherein the twisting of the plurality of fibers in the second direction is for a predefined number of twists, the predefined number of twists in the second direction being same as the predefined number of twists in the first direction. 
     
     
         4 . The process of  claim 1 , wherein the twisting of the plurality of fibers in the first direction is based on a twist per meter. 
     
     
         5 . The process of  claim 4 , wherein the twisting of the plurality of fibers in the second direction is based on a twist per meter, the twist per meter in the second direction being the same as the twist per meter of the first direction. 
     
     
         6 . The process of  claim 1 , wherein the twisting of the plurality of fibers in the first direction is in a ‘S’ direction or ‘Z’ direction. 
     
     
         7 . The process of  claim 1 , wherein the twisting of the plurality of fibers in the second direction is in a direction opposite to the twisting of the plurality of the fibers in the first direction. 
     
     
         8 . A process for manufacturing a yarn, comprising:
 twisting the yarn in a first direction for a predefined number of twists or predefined number of time;   after the predefined number of twists or after predefined number of time, twisting the yarn in a second direction for a predefined number of twists or predefined number of time, the predefined number of twists or the predefined number of time for the second yarn is same as the predefined number of twists or the predefined number of time for the first yarn, wherein   the twisting of the yarn in the second direction creates an air bed within the yarn's fibers.   
     
     
         9 . The process of  claim 8 , further comprising:
 alternating twisting of the fibers of the yarn between the first direction and the second direction to trap air within the fibers.   
     
     
         10 . The process of  claim 9 , wherein the trapping of the air results in an expansion of the yarn.
