Fiber mix for yarn and fabrics

Abstract

A yarn comprises a blend of two or more types of fibers. Fibers of viscose incorporating silica compose 50-85% by weight of the yarn. Fibers of modacrylic compose 15-50% by weight of the yarn. A composite yarn with a core being defined by the yarn is also provided. The composite yarn has a sheath surrounding the core.

1 . A yarn comprising:
 a blend of at least two types of fibers, including at least   fibers of viscose incorporating silica composing 50-85% by weight of the yarn, and   fibers of modacrylic composing 15-50% by weight of the yarn.   
     
     
         2 . The yarn according to  claim 1 , wherein the fibers of viscose have a linear mass density ranging between 1.5 and 3.5 deniers, inclusively. 
     
     
         3 . The yarn according to  claim 1 , wherein the fibers of viscose are staple fibers of viscose. 
     
     
         4 . The yarn according to  claim 3 , wherein a substantial portion of the staple fibers are between 35 mm and 120 mm in length. 
     
     
         5 . The yarn according to  claim 1 , wherein the fibers of modacrylic have a linear mass density ranging between 1.0 and 3.0 deniers, inclusively. 
     
     
         6 . The yarn according to  claim 1 , wherein the fibers of modacrylic are staple fibers. 
     
     
         7 . The yarn according to  claim 6 , wherein a substantial portion of the staple fibers of modacrylic are between 35 mm and 120 mm in length. 
     
     
         8 . The yarn according to  claim 1 , wherein the blend of fibers has a fiber-to-fiber dispersion of the fibers. 
     
     
         9 . The yarn according to  claim 1 , further including fibers of meta-aramid composing at most 20% by weight of the yarn. 
     
     
         10 . The yarn according to  claim 1 , further including fibers of para-aramid composing at most 20% by weight of the yarn. 
     
     
         11 . The yarn according to  claim 1 , further including fibers of nylon composing at most 20% by weight of the yarn 
     
     
         12 . The yarn according to  claim 1 , wherein a yarn count is between 20 tex and 250 tex, inclusively. 
     
     
         13 . A composite yarn comprising:
 a core, the core being defined by the yarn according to  claim 1 ; and   a sheath surrounding the core.   
     
     
         14 . The composite yarn according to  claim 13 , wherein the sheath includes cellulosic fibers. 
     
     
         15 . The composite yarn according to  claim 14 , wherein the cellulosic fibers are cotton fibers, lyocell, or viscose fibers. 
     
     
         16 . The composite yarn according to  claim 14 , wherein the sheath is 100% cotton fibers. 
     
     
         17 . The composite yarn according to  claim 15 , wherein the cotton is non-treated. 
     
     
         18 . The composite yarn according to  claim 14 , wherein the sheath includes nylon fibers. 
     
     
         19 . The composite yarn according to  claim 13 , wherein the sheath has fibers of corespun around the core.
