Stretchable and dimensionally stable woven fabric made from polytrimethylene terephthalate based core spun yarns.

Abstract

A core spun yarn, wherein the core is a stretchable filament and is surrounded by a sheath of polytrimethylene terephthalate based staple fibers in combination with a second staple fiber. A fabric is made using the core spun yarn. The fabric produced from the core spun yarn is highly stretchable, has high dimensional stability, low growth and high recovery.

We claim: 
     
         1 . A core spun yarn comprising a core comprising a stretchable filament surrounded by a sheath comprising a polytrimethylene terephthalate based staple fiber in combination with a second staple fiber. 
     
     
         2 . The core spun yarn of  claim 1  wherein the stretchable filament is a spandex filament. 
     
     
         3 . The core spun yarn of  claim 1  wherein the second fiber is selected from a group consisting of cotton, viscose, polyester, nylon, modal, tencel, wool and combinations thereof. 
     
     
         4 . The core spun yarn of  claim 1  wherein the polytrimethylene terephthalate based staple fiber content in the sheath is in the range of 10% to 60%. 
     
     
         5 . The core spun yarn of  claim 2  wherein the spandex filament content is in the range of 2 to 10%. 
     
     
         6 . The core spun yarn of  claim 1  wherein the second staple fiber is a cotton staple fiber. 
     
     
         7 . A fabric comprising a core spun yarn comprising a core comprising a stretchable filament surrounded by a sheath comprising a polytrimethylene terephthalate based staple fiber in combination with a second staple fiber. 
     
     
         8 . The fabric of  claim 7  wherein the fabric has weft yarn and warp yarn and wherein the core spun yarn is the weft yarn and the warp yarn is selected from a group consisting of cotton, nylon, polyester, wool, viscose and combinations thereof. 
     
     
         9 . The fabric as claimed in  claim 7  wherein the fabric has a stretch recovery in the range of 75 to 95% and a growth of <2.3%. 
     
     
         10 . The fabric of  claim 7  wherein the fabric is used for applications selected from the group consisting of garments, sheeting material, furnishings, and upholstery.
