Core yarn comprising core thread with variant drawing, and fabric that is obtained from this core yarn

Abstract

A core yarn including at least one core part. The at least one core part includes at least one elastane thread having a plurality of areas with different densities and/or, the at least one core part includes at least one filament thread having a plurality of areas with different densities and are made of regenerated or synthetic materials.

What is claimed is: 
     
         1 . A core yarn comprising at least one core part, wherein,
 the at least one core part comprises at least one elastane thread having a plurality of areas with different densities and/or,   the at least one core part comprises at least one filament thread having a plurality of areas with different densities and are made of regenerated or synthetic materials.   
     
     
         2 . The thread according to  claim 1 , wherein; the plurality of areas of the at least one elastane thread have different lengths and densities along the at least one elastane thread. 
     
     
         3 . The thread according to  claim 1 , wherein; the plurality of areas of the at least one elastane thread have same lengths and densities along the at least one elastane thread. 
     
     
         4 . The thread according to  claim 1 , wherein; the plurality of areas of the at least one filament thread have different lengths and densities along the at least one filament thread. 
     
     
         5 . The thread according to  claim 1 , wherein; the plurality of areas of the at least one filament thread have same lengths and densities along the at least one filament thread. 
     
     
         6 . A method of production of the core yarn of  claim 1 , the method comprising the steps of:
 preparing natural fibers, regenerated fibers, synthetic fibers or fibers having a combination of the natural fibers, regenerated fibers and the synthetic fibers for a spinning process and roving into a cord;   applying the spinning process to the cord;   feeding the at least one filament thread comprising of regenerated or synthetic materials and/or the at least one elastane thread, with different drawing values to a core part of the cord drawn during the spinning process;   applying twisting and winding to a bobbin.   
     
     
         7 . A thread spinning setting of the method according to  claim 6 , which enables an application of the method of production of the core yarn after the step of roving the cord; wherein the thread spinning setting comprises:
 a feeding part,   a drawing part comprising a back drawing roller, a middle drawing roller and a front drawing roller located one after another, a back sleeve located on the back drawing roller, a middle sleeve located on the middle drawing roller and a front sleeve located on the front drawing roller;   twisting and winding parts;   an elastane thread drive roller having a elastane thread reel attached therein for feeding of the at least one elastane thread to the drawing part and/or a filament thread drive roller for feeding the at least one filament thread to the drawing part;   a drive motor and an inverter for providing a movement to the elastane thread drive roller and alter a velocity of the elastane thread drive roller and/or for providing a movement to the filament thread drive roller and alter a velocity of the filament thread drive roller;   and a data entrance screen, wherein velocity values depending on a length of the at least one elastane thread and/or the at least one filament thread are entered in the data entrance screen.   
     
     
         8 . The thread spinning setting according to  claim 7 , wherein
 the elastane thread drive roller feeds the at least one elastane thread in between the front drawing roller and the front sleeve in the drawing part, and/or   the filament thread drive roller feeds the at least one filament thread in between the front drawing roller and the front sleeve in the drawing part.   
     
     
         9 . A fabric comprising the core yarn according to  claim 1 . 
     
     
         10 . The fabric according to  claim 9 , wherein the fabric is a textile or a knitted fabric. 
     
     
         11 . The fabric according to  claim 9 , wherein, the plurality of areas of the at least one elastane thread have different lengths and densities along the at least one elastane thread. 
     
     
         12 . The fabric according to  claim 9 , wherein, the plurality of areas of the at least one elastane thread have same lengths and densities along the at least one elastane thread. 
     
     
         13 . The fabric according to  claim 9 , wherein, the plurality of areas of the at least one filament thread have different lengths and densities along the at least one filament thread. 
     
     
         14 . The fabric according to  claim 9 , wherein, the plurality of areas of the at least one filament thread have same lengths and densities along the at least one filament thread.
