Light and Thin Fabric for Comfortably Expelling Sweat

Abstract

A light and thin fabric which is made by juxtapostionally knitting a hydrophilic yarn on a hydrophobic yarn by repeatedly juxtapositionally plating the hydrophilic yarn on the hydrophobic yarn to form an inner hydrophobic sublayer consisting of a plurality of inner hydrophobic loops, and an outer hydrophilic sublayer consisting of a plurality of outer hydrophilic loops, whereby the inner hydrophobic loops are adapted to be proximate or contacted with a wearer's skin or body to capillarily transfer the moisture or sweat as discharged from the wearer towards the outer hydrophilic loops; and whereby the outer hydrophilic loops are adapted to absorb the moisture or sweat from the inner hydrophobic loops to diffuse the moisture and evaporate as vapor outwardly.

I claim: 
     
         1 . A method for making a fabric comprising:
 repeatedly knitting an outer hydrophilic yarn on an inner hydrophobic yarn by juxtapositionally feeding said hydrophilic yarn and said hydrophobic yarn into double feeding ports of a single-knit circular knitting machine and repeatedly plating said outer hydrophilic yarn on said inner hydrophobic yarn to juxtapositionally superimpose said outer hydrophilic yarn on said inner hydrophobic yarn to form a plurality of hydrophobic loops for constructing an inner hydrophobic sublayer adapted to be proximate or contacted with a wearer's skin or body to capillarily transfer moisture of a wearer's sweat outwardly, and form a plurality of hydrophilic loops for constructing an outer hydrophilic sublayer adapted for absorbing moisture as transferred from said inner hydrophobic sublayer to be outwardly diffused and evaporated as vapor to be released from said outer hydrophilic sublayer.   
     
     
         2 . A method according to  claim 1 , wherein said hydrophobic yarn is selected from polyester or nylon. 
     
     
         3 . A method according to  claim 1 , wherein said hydrophilic yarn is a polyester or nylon which is processed to be hydrophilic as treated with water absorbent agent. 
     
     
         4 . A method according to  claim 1 , wherein said inner hydrophobic yarn is a fine denier hydrophobic polyester yarn having a fineness of 20˜50 deniers; and said outer hydrophilic yarn is a coarse denier hydrophilic polyester yarn having a fineness of 40˜200 deniers. 
     
     
         5 . A method according to  claim 1 , wherein said fabric has an area density (or a weight per unit area) of at least 110 g/m 2 . 
     
     
         6 . A method according to  claim 1 , wherein said fabric includes an elastic yarn, having an area density of at least 130 g/m 2 . 
     
     
         7 . A method according to  claim 4 , wherein said fabric has an elasticity ranging from 30˜200%. 
     
     
         8 . A fabric comprising:
 an inner hydrophobic sublayer consisting of a plurality of inner hydrophobic loops adapted to be proximate or contacted with a wearer's skin or body for capillarily transferring the wearer's sweat or moisture outwardly; and   an outer hydrophilic sublayer consisting of a plurality of outer hydrophilic loops, each said outer hydrophilic loop juxtapositionally superimposed on each said inner hydrophobic loop for absorbing moisture as outwardly transferred from said inner hydrophobic loop to be diffused or evaporated as vapor outwardly for quickly drying the wearer's skin or body; and   each said inner hydrophobic loop formed with an inner hydrophobic yarn;   each said outer hydrophilic loop formed with an outer hydrophilic yarn juxtapositionally plated by knitting on said inner hydrophobic yarn of said inner hydrophobic loop.   
     
     
         9 . A fabric according to  claim 8 , wherein said hydrophobic yarn is selected from polyester or nylon. 
     
     
         10 . A fabric according to  claim 8 , wherein said hydrophilic yarn is a polyester or nylon which is processed to be hydrophilic as treated with water absorbent agent. 
     
     
         11 . A fabric according to  claim 8 , wherein said inner hydrophobic yarn is a fine denier hydrophobic polyester yarn having a fineness of 20˜50 deniers; and said outer hydrophilic yarn is a coarse denier hydrophilic polyester yarn having a fineness of 40˜200 deniers.
