Elastic yarn, knitted textile material and sock made with the elastic yarn

Abstract

An elastic yarn is provided comprising at least one elastic filament and at least one further filament, which form a core of the yarn. As different regions of a garment, e.g. socks, need to have different properties in view of recovery, comfort and robustness, and as it is important that the respective articles are easy to produce in the elastic yarn, the elastic filament has a draft between 0.2 and 15.0, and the further filament has a draft of between 0.2 and 5.0.

1 . An elastic yarn comprising at least one elastic filament and at least one further filament, which are twisted to form a core of the yarn, wherein the elastic filament has a draft between 0.2 and 15.0, and the further filament has a draft of between 0.2 and 5.0. 
     
     
         2 . The elastic yarn according to  claim 1 , wherein the elastic filament has a draft between 0.2 and 12.0. 
     
     
         3 . The elastic yarn according to  claim 1 , wherein the further filament has a draft of between 1 and 1.3. 
     
     
         4 . The elastic yarn according to  claim 1 , wherein the twist of the core is between 300 and 1100. 
     
     
         5 . The elastic yarn according to  claim 1 , wherein the twist of the core is between 400 and 500. 
     
     
         6 . The elastic yarn according to  claim 1 , wherein the further filament is an inelastic filament. 
     
     
         7 . The elastic yarn according to  claim 1 , wherein the further filament is chosen from the group of polyether sulfones, Polybutylene terephthalate (PBT), Partial Oriented Yarn (POY), polyamide, polyester. 
     
     
         8 . The elastic yarn according to  claim 1 , wherein the elastic filament is elastane. 
     
     
         9 . The elastic yarn according to  claim 1 , wherein the core is surrounded by a cover layer to form the yarn, wherein the cover layer comprises staple fibers. 
     
     
         10 . The elastic yarn according to  claim 9 , wherein the staple fibers are chosen from the group of natural, recycled and/or synthetic fibers and/or fibers made of the following materials: cotton, viscose, polyester, wool, linen, alpaca, vicuna, angora, cashmere, kapok, manila, flax, hemp, ramie, hessian, sisal, coir, asbestos, glass, azlon, acetate, triacetate, acrylic, aramid, polyamide, olefin, or a mixture thereof. 
     
     
         11 . The elastic yarn according to  claim 1 , wherein the core made from twisted filaments comprises more than 3 filaments and less than 6 filaments. 
     
     
         12 . The elastic yarn according to  claim 1 , wherein the core comprises 2 or 3 elastic filaments each having a draft between 0.2 and 15. 
     
     
         13 . The elastic yarn according to  claim 1 , wherein the core comprises 1 or 2 or 3 inelastic filaments each having a draft of a draft of between 0.2 and 5. 
     
     
         14 . A knitted textile material, comprising the yarn according to  claim 1 , wherein the textile material comprises at least two different knitting pattern, wherein the same yarn material is used as only material setting up the different knitting pattern. 
     
     
         15 . A sock which is made entirely from one single type of yarn, wherein the yarn is a yarn according to  claim 1 . 
     
     
         16 . The sock according to  claim 15 , wherein the core comprises 1 or 2 or 3 inelastic filaments each having a draft of a draft of between 0.2 and 5.
