Claims
- 1. A slickened polyester fiberfill batt or a garment or other article filled with slickened polyester fiberfill, wherein the slickened polyester fiberfill is secured to a continuous flexible layer of a waterproof hydrophilic elastomer having a water vapor transmission rate of at least 3500 gm.mil/m2/24hrs, according to ASTM E96-66 (Procedure BW), said hydrophilic elastomer being a copolyetherester elastomer or a mixture of two or more copolyetherester elastomers having a multiplicity of long-chain ester units and short-chain ester units joined head-to-tail through ester linkages, said long-chain ester units being represented by the formula ##STR5## and said short-chain ester units being represented by the formula: ##STR6## where G is a divalent radical remaining after the removal of terminal hydroxyl groups from a poly(alkylene oxide) glycol having an average molecular weight of about 400-3500, and further, the amount of ethylene oxide groups incorporated in the copolyetherester or mixture of two or more copolyetheresters by the poly(alkylene oxide) glycol is from about 25-68 weight percent based upon the total weight of the copolyetherester or mixture of two or more copolyetheresters; R is a divalent radical remaining after removing of carboxyl groups from a dicarboxylic acid having a molecular weight less than 300; D is a divalent radical remaining after removal of hydroxyl groups from a diol having a molecular weight less than about 250; and said hydrophilic copolyetherester or mixture of two or more copolyetheresters has from about 25-80 weight percent short-chain ester units.
- 2. A slickened polyester fiberfill batt or garment or other article according to claim 1, wherein the fiberfill is secured to said continuous flexible layer of said hydrophilic elastomer via an intervening layer of a hydrophobic elastomer having a water vapor transmission rate of 400-2500 gm.mil/m.sup.2 /24hrs, said hydrophobic elastomer is a copolyetherester elastomer or a mixture of two or more copolyetherester elastomers having a multiplicity of recurring long-chain ester units and short-chain ester units, said long-chain ester units being represented by the formula: ##STR7## and said short-chain ester units being represented by the formula: ##STR8## where G is a divalent radical remaining after the removal of terminal hydroxyl groups from a poly(alkylene oxide) glycol having an average molecular weight of about 400-3500, the amount of ethylene oxide groups incorporated in the copolyetherester by the poly(alkylene oxide)glycol is not greater than about 20 weight percent; R is a divalent radical remaining after removal of carboxyl groups from a dicarboxylic acid having a molecular weight less than 300; and D is a divalent radical remaining after removal of hydroxyl groups from a diol having a molecular weight less than about 250; and said hydrophobic copolyetherester or mixture of two or more copolyetheresters has from about 5-80 weight percent short-chain ester units.
- 3. A slickened polyester fiberfill batt or garment or other article according to claim 2, wherein the fiberfill is discontinuously bonded to said hydrophobic elastomer by an adhesive.
- 4. A slickened polyester fiberfill batt or garment or other article according to claim 3, wherein said hydrophobic elastomer is bonded to the fiberfill by means of binder fibers having a melting point that is lower than that of the polyester fiberfill and lower than that of said hydrophobic elastomer.
