Heat-resistant knitted underwear

Abstract

An underwear including a pair of side portions disposed on a front portion of the underwear, the pair of side fabric portions including fabric comprising warps aligned in a longitudinal direction of the underwear and welfs generally disposed at an angle from the warps allowing the fabric to stretch in a transversal direction, and a center fabric portion disposed on a rear portion of the underwear, the center fabric portion including warps aligned in the transversal direction of the underwear and welfs generally disposed at an angle from the warps allowing the center fabric portion to stretch in the longitudinal direction, the fabric includes no-melt no-drip heat-resistant material and wherein the stretching property of the fabric is mechanically provided by the weaving thereof, whereby the center fabric portion is adapted to longitudinally stretch when a wearer is bending forward to cover a wearer's lower back.

What is claimed is: 
     
         1 . A no-melt no-drip underwear comprising:
 a front portion, the front portion including a pair of side fabric portions secured on lateral sides of a middle fabric portion, the pair of side fabric portions including warps generally aligned in a longitudinal direction of the underwear and welfs generally disposed at an angle from the warps allowing the fabric to stretch in a transversal direction; and   a rear portion, opposed to the front portion, the rear portion including a pair of side fabric portions secured on lateral sides of a center fabric portion, the pair of side fabric portions including warps generally aligned in a longitudinal direction of the underwear and welfs generally disposed at an angle from the warps allowing the fabric to stretch in a transversal direction, the center fabric portion including fabric comprising warps generally aligned in the transversal direction of the underwear and welfs generally disposed at an angle from the warps allowing the center fabric portion to stretch in the longitudinal direction,   wherein the fabric portions include no-melt no-drip heat-resistant material and wherein the stretching property of the fabric is mechanically provided by the knitting thereof,   whereby the center fabric portion is adapted to longitudinally stretch when a wearer is bending forward to cover a wearer's lower back.   
     
     
         2 . The no-melt no-drip underwear of  claim 1 , wherein the fabric portions include natural fibers therein. 
     
     
         3 . The no-melt no-drip underwear of  claim 1 , wherein the fabric portions include yarns that has minimal stretching capability. 
     
     
         4 . The no-melt no-drip underwear of  claim 1 , wherein the center fabric portion includes a “V” shape.

         6 . The no-melt no-drip underwear of  claim 1 , wherein the center fabric portion is secured to the side fabric portions with joint disposed at an angle in respect with a leg axis. 
     
     
         7 . A fire-resistant underwear comprising fabric devoid of polymer, the fabric being woven with a weaving including at least two distinct sets of interlaced yarns capable of temporarily stretching in one direction when tension is applied to the fabric in the at least one direction, the fabric recovering its original size when tension thereon is released, the underwear further comprising a rear portion including a pair of side fabric portions disposed on lateral sides of a center fabric portion, the center fabric portion including longitudinal stretching capability,
 wherein the fabric includes no-melt no-drip heat-resistant material and wherein the stretching property of the fabric is mechanically provided by the weaving thereof,   whereby the center fabric portion is adapted to longitudinally stretch when a wearer is bending forward to cover a wearer's lower back.   
     
     
         8 . The fire-resistant underwear of  claim 7 , wherein the fabric portions include natural fibers therein. 
     
     
         9 . The fire-resistant underwear of  claim 7 , wherein the fabric portions include yarns that has minimal stretching capability. 
     
     
         10 . The fire-resistant underwear of  claim 7 , wherein the center fabric portion includes a “V” shape. 
     
     
         11 . The fire-resistant underwear of  claim 7 , wherein the center fabric portion includes a “U” shape. 
     
     
         12 . The fire-resistant underwear of  claim 7 , wherein the center fabric portion is secured to the side fabric portions with joint disposed at an angle in respect with a leg axis.
