Reinforcing structure comprising spun staple yarns

Abstract

This invention pertains to a tire, a transfer hose, a hydraulic hose, a conveyor belt or a power transmission belt comprising a structural fibrous reinforcing component, the component further comprising spun staple yarn having a linear density corresponding to a cotton count of from 17/1 to 10/5.

We claim: 
     
         1 . A tire, a transfer hose, a hydraulic hose, a conveyor belt or a power transmission belt comprising a structural fibrous reinforcing component, the component further comprising spun staple yarn having a linear density corresponding to a cotton count of from 17/1 to 10/5. 
     
     
         2 . The component of  claim 1 , wherein the yarn is penetrated by a surface coating for promoting adhesion to rubber such that the coating comprises from 0.1 to 25 weight percent of the yarn plus coating. 
     
     
         3 . The component of  claim 1 , wherein the spun staple yarn has a linear density corresponding to a cotton count of from 10/2 to 10/4. 
     
     
         4 . The component of  claim 1 , wherein the yarn is a singles yarn comprising a blend of fibers. 
     
     
         5 . The component of  claim 1 , wherein the yarn is a blend of yarns that are twisted together to form a merged yarn. 
     
     
         6 . The component of  claim 1 , wherein the yarn is a sheath-core yarn comprising at least one continuous filament in the core and spun staple yarn in the sheath. 
     
     
         7 . The component of  claim 1 , wherein the spun staple yarn is aromatic polyamide, aromatic copolyamide, aliphatic polyamide, polyester, rayon, carbon, glass, modacrylic, polyolefin, acrylic, polyazole, liquid crystal polymer, cellulose, lyocell, polylactic acid, metal or blends thereof. 
     
     
         8 . The component of  claim 1  in the form of a tire carcass, sidewall, belt, overlay, breaker, chipper, flipper or subtread. 
     
     
         9 . The component of  claim 2 , wherein the yarn is penetrated by a surface coating such that the coating comprises from 1 to 20 weight percent of the yarn plus coating. 
     
     
         10 . The component of  claim 6 , wherein the core material is inorganic. 
     
     
         11 . The component of  claim 7 , wherein the aromatic polyamide is para-aramid. 
     
     
         12 . The component of  claim 8 , wherein the yarn is penetrated by a surface coating such that the coating comprises from 2 to 15 weight percent of the yarn plus coating. 
     
     
         13 . A method of reducing tire noise in a vehicle by providing a component in a tire comprising spun staple yarn having a linear density corresponding to a cotton count of from 17/1 to 10/5.
