Textile laminate

Abstract

A textile laminate includes a hydrophobic membrane, an inner fabric layer and an outer fabric layer sandwiching the hydrophobic membrane. The hydrophobic membrane has a plurality of tangled polymer fibers, a plurality of pores among the polymer fibers, and a plurality of adhesive powder attached on the polymer fibers on the top and bottom surfaces. The grain size of each adhesive powders is small enough to remain the pores without obstructing permeability. The pores in the PTFE film are water vapor permeable and liquid water impermeable.

1 . A textile laminate comprising: 
 a hydrophobic membrane with a top surface and a bottom surface, the hydrophobic membrane having a plurality of tangled polymer fibers, a plurality of pores among the polymer fibers, and a plurality of adhesive powder attached to the polymer fibers on the top surface and the bottom surface, and a grain size of each adhesive powder is small enough to remain the pores without obstructing permeability;    an outer fabric layer bonded on the top surface of the hydrophobic membrane by the adhesive powder located on the top surface of the hydrophobic membrane; and    an inner fabric layer bonded on the bottom surface of the hydrophobic membrane by the adhesive powder located on the bottom surface of the hydrophobic membrane;    wherein the pores in the hydrophobic membrane are water vapor permeable and liquid water impermeable.    
   
   
       2 . The textile laminate as claimed in  claim 1  wherein the hydrophobic membrane comprises a PTFE (polyterafluoroethylene) film and the polymer fibers are PTFE fibers.  
   
   
       3 . The textile laminate as claimed in  claim 1  wherein the outer fabric layer comprises synthetic or natural fibers or blends thereof.  
   
   
       4 . The textile laminate as claimed in  claim 1  wherein the inner fabric layer comprises a hydrophilic material.  
   
   
       5 . The textile laminate as claimed in  claim 4  wherein the inner fabric layer comprises cotton, wool, felt, synthetic fibers, or a combination thereof.  
   
   
       6 . The textile laminate as claimed in  claim 1  wherein the inner fabric layer comprises a hydrophilic material with high hydrophilicity and rewetting properties to provide a rapid water absorption ability and improve a water diffusion ability of the textile laminate.  
   
   
       7 . The textile laminate as claimed in  claim 1  wherein the grain size of the adhesive powder have diameters about 50 to 500 nm in diameter.  
   
   
       8 . A garment formed of the textile laminate as claimed in  claim 1  wherein the inner fabric layer is an inner side of the garment in contact with a wearer and the outer fabric layer is an outer side of the garment exposed to the environment.  
   
   
       9 . A textile laminate comprising: 
 a hydrophobic membrane with a top surface and a bottom surface, the hydrophobic membrane having a plurality of tangled polymer fibers, a plurality of pores among the polymer fibers, and a plurality of adhesive powder attached to the top surface and the bottom surface of hydrophobic membrane;    an outer fabric layer bonded on the top surface of the hydrophobic membrane by the adhesive powder located on the top surface of the hydrophobic membrane; and    an inner fabric layer comprising a hydrophilic material bonded on the bottom surface of the hydrophobic membrane by the adhesive powder located on the bottom surface of the hydrophobic membrane;    wherein the pores in the hydrophobic membrane are water vapor permeable and liquid water impermeable.    
   
   
       10 . The textile laminate as claimed in  claim 9  wherein the hydrophobic membrane comprises a PTFE (polyterafluoroethylene) film and the polymer fibers are PTFE fibers.  
   
   
       11 . The textile laminate as claimed in  claim 9  wherein the outer fabric layer comprises synthetic or natural fibers or blends thereof  
   
   
       12 . The textile laminate as claimed in  claim 9  wherein the inner fabric layer comprises cotton, wool, felt, synthetic fibers, or a combination thereof.  
   
   
       13 . The textile laminate as claimed in  claim 9  wherein the inner fabric layer comprises a hydrophilic material with high hydrophilicity and rewetting properties to provide a rapid water absorption ability and improve a water diffusion ability of the textile laminate.  
   
   
       14 . A garment formed of the textile laminate as claimed in  claim 9  wherein the inner fabric layer is an inner side of the garment in contact with a wearer and the outer fabric layer is an outer side of the garment exposed to the environment.
