Textile with a controlled elasticity for the forming of elements of garments, underwear, orthoses, and seat elements

Abstract

A textile for the forming of elements of underwear, of garments, of orthoses, or of seat elements having a controlled elasticity, integrating, at least in the direction of the main effort, stretch yarns having an elastic characteristic. Said stretch yarns are associated with more highly stretchable yarns, having greater stretching characteristics than those of the stretch yarns, the return force exerted by the low stretch yarns being in the range from 25 to 50% of that exerted by the high stretch yarns.

1 . A textile for the forming of elements of underwear, of garments, of orthoses, or of seat elements having a controlled elasticity, integrating at least in one direction of the main effort, stretch yarns having an elastic characteristic, wherein said stretch yarns, are associated with more highly stretchable yarns, having greater stretching characteristics than those of the stretch yarns, and wherein the return force exerted by the stretch yarns is in the range from 25 to 50% of that exerted by the highly stretchable yarns. 
     
     
         2 . The textile for the forming of elements of underwear, of garments, of orthoses, or of seat elements having a controlled elasticity of  claim 1 , wherein the stretching capacity of the stretch yarns is close to 50% of that of the highly stretchable yarns. 
     
     
         3 . The textile for the forming of elements of underwear, of garments, of orthoses, or of seat elements having a controlled elasticity of  claim 1 , wherein the respective proportion of highly stretchable yarns and of the stretch yarns is close to 50-50. 
     
     
         4 . The textile for the forming of elements of underwear, of garments, of orthoses, or of seat elements having a controlled elasticity of  claim 2 , wherein the respective proportion of highly stretchable yarns and of stretch yarns is close to 50-50. 
     
     
         5 . The textile for the forming of elements of underwear, of garments, of orthoses, or of seat elements having a controlled elasticity of  claim 1 , wherein both yarns provided with elastic characteristic integrated in the textile are covered yarns having their respective core made of elastane, of polyurethane, of silicone, or of elastodiene, and having their respective cover made of polyamide, of polyester, or other synthetic yarns or fibers. 
     
     
         6 . The textile for the forming of elements of underwear, of garments, of orthoses, or of seat elements having a controlled elasticity of  claim 1 , wherein both yarns provided with elastic characteristic are integrated in a structure having a weave exhibiting a shrinkage, the shrinkage being selected to always be greater than the stretching capacity of the highly stretchable yarns. 
     
     
         7 . The textile for the forming of elements of underwear, of garments, of orthoses, or of seat elements having a controlled elasticity of  claim 1 , wherein said textile is a woven, knitted, or braided fabric. 
     
     
         8 . A shoulder strap for underwear or sportswear, implementing the textile of  claim 1 , wherein the maximum stretching of said strap is approximately 90% with respect to its initial length, for a return force for a 30% stretching close to 400 cN/cm. 
     
     
         9 . A shorts or underwear waistband, particularly for a use in sports, implementing the textile of  claim 1 , wherein the maximum stretching of said waistband is from approximately 120 to 150% of the initial length of the fabric forming said waistband, for a return force for a 30% stretching in the range from 220 to 300 cN/cm.
