Combination yarn

Abstract

An improved yarn is described. The yarn includes an outer layer, a first internal thread, a second internal thread, and a helical thread. The helical thread is woven on the first internal thread in a helical pattern. The second internal thread is positioned adjacent and in parallel to the first internal thread. The outer layer encloses the first and second internal threads and the helical thread.

What is claimed: 
     
         1 . A yarn comprising:
 an outer layer, a first internal thread, a second internal thread, and a helical thread, wherein
 the helical thread is woven on the first internal thread in a helical pattern, and wherein 
 the outer layer encloses the first and second internal threads and the helical thread. 
   
     
     
         2 . The yarn of  claim 1 , wherein the first internal thread includes one or more of: a cotton, a polyester, a polypropylene, and a synthetic cellulose yarn-based material. 
     
     
         3 . The yarn of  claim 2 , wherein the first internal thread includes the cotton-based material. 
     
     
         4 . The yarn of  claim 1 , wherein the helical thread and the second internal threads include an elastic polyurethane-based material. 
     
     
         5 . The yarn of  claim 1 , wherein the helical thread and the second internal threads include one or more of a polybutylene terephthalate, a polyester, and a polypropylene based material. 
     
     
         6 . The yarn of  claim 1 , wherein the first and second internal threads are positioned adjacent and in parallel. 
     
     
         7 . The yarn of  claim 1 , wherein the outer layer forms a tube around the first and second internal threads and the helical thread. 
     
     
         8 . The yarn of  claim 1 , wherein the first internal thread and a combination of the helical thread and the second internal thread include a weight ratio between about 5:1 to about 30:1. 
     
     
         9 . The yarn of  claim 1 , wherein the first internal thread comprises between about 60% to about 96.5% of a weight of the yarn. 
     
     
         10 . The yarn of  claim 1 , wherein the helical thread and the second internal thread comprise between about 1.5% to about 10% of a weight of the yarn. 
     
     
         11 . The yarn of  claim 1 , wherein the helical pattern of the helical thread wrapped on the first internal thread includes a twist value between about 9 threads per inch (TPI) and about 30 TPI. 
     
     
         12 . The yarn of  claim 1 , wherein the first internal thread includes a denier between about 30 and 200. 
     
     
         13 . The yarn of  claim 1 , wherein the helical thread and the second internal thread include a denier between about 20 and 150. 
     
     
         14 . A yarn comprising:
 an outer layer, first and second internal threads, and a helical thread, wherein
 the outer layer includes one or more of a cotton, a polyester, a polypropylene, and a synthetic cellulose yarn-based material, wherein 
 the first internal thread includes one or more of a cotton, a polyester, a polypropylene, and a synthetic cellulose yarn-based material, wherein 
 the helical thread and the second internal thread include an elastic polyurethane-based material, wherein 
 the helical thread is woven on the first internal thread in a helical pattern, wherein 
 the first and second internal threads are positioned adjacent and in parallel, and wherein 
 the outer layer forms a tube around the first and second internal threads and the helical thread. 
   
     
     
         15 . A method of producing a yarn, the method comprising:
 weaving a helical thread on a first internal thread using a helical pattern, wherein
 the helical thread includes an elastic polyurethane-based material, and wherein 
 the first internal thread includes one or more of a cotton, a polyester, a polypropylene, and a synthetic cellulose yarn-based material; 
   positioning a second internal thread adjacent and in parallel to the first internal thread,
 wherein the second internal thread includes the elastic polyurethane-based material; and 
   encapsulating the helical thread and the first and second internal threads with an outer layer, wherein the outer layer includes one or more of a cotton, a polyester, a polypropylene, and a synthetic cellulose yarn-based material.
