Moisture-permeable, waterproof and windproof laminated sheet, interlining using the same, and garment containing the interlining

Abstract

A laminated sheet made by bonding a nonwoven fabric to a non-porous waterproof, windproof and moisture permeable film. The bonding may be carried out by hot pressing in combination with a hot-melt adhesive and the laminated sheet may have a water vapor transmission rate of 1,000 to 10,000 g/m 2 ·h. The laminated sheet may be further bonded to a face fabric, making the resulting structure particularly suitable for use in the construction of garments.

1 . A laminated sheet comprising a laminate produced by bonding and laminating a nonwoven fabric with a nonporous waterproof and windproof moisture-permeable film. 
     
     
         2 . The laminated sheet of  claim 1 , wherein the nonwoven fabric in the laminate has an adhesive layer dispersed and coated over substantially the entire surface thereof. 
     
     
         3 . The laminated sheet of  claim 1  or  2 , wherein the laminate has a water vapor transmission rate, as measured by method A-1 described in section 4.1.1 of JIS L-1099, of 1,000 to 20,000 g/m 2 ·24 h; an air permeability, as measured according to JIS L-1018, of up to 30 cm 3 /cm 2 /s; and a water pressure resistance, as measured according to JIS L-1092, of 100 to 40,000 mm. 
     
     
         4 . A laminated sheet according to any one of  claims 1  to  3 , wherein the film is hydrophilic. 
     
     
         5 . The laminated sheet according to any one of  claims 1  to  4 , wherein the film is made of a polyesterether elastomer. 
     
     
         6 . The laminated sheet according to any one of  claims 1  to  5 , wherein the film is made of a polyesterether elastomer prepared by ester linkages between long-chain ester repeating units of formula (I) below and short-chain ester repeating units of formula (II) below. 
       
         
           
           
               
               
           
         
       
       wherein:
 a) G is a divalent radical remaining after the removal of terminal hydroxyl groups from a poly(alkylene oxide)glycol having a number average molecular weight of about 400-4000; 
 b) R is a divalent radical remaining after removal of carboxyl groups from a dicarboxylic acid having a molecular weight less than 300; 
 c) D is a divalent radical remaining after removal of hydroxyl groups from a diol having a molecular weight less than about 250; optionally 
 d) the copolyetherester contains 0-68 weight percent based on the total weight of the copolyetherester, ethylene oxide groups incorporated in the long-chain ester units of the copolyetherester; and 
 e) the copolyetherester contains about 25-80 weight percent short-chain ester units. 
 
     
     
         7 . The laminated sheet of any one of  claims 1  to  6 , wherein the laminate is produced by bonding the nonwoven fabric and the film with a hot-melt adhesive. 
     
     
         8 . The laminated sheet of any one of  claims 5  to  7 , wherein the nonwoven fabric is made with polyester fibers and the hot melt adhesive is composed primarily of a polyester resin. 
     
     
         9 . An interlining which contains the laminated sheet of any one of  claims 1  to  8 . 
     
     
         10 . A garment or fabric which uses the interlining of  claim 9 .
