  • Publication number: 20060035549
    Abstract: A water-vapor-permeable waterproof composite fabric having high flexibility, water pressure resistance and water laundering resistance is constituted from a substrate fabric and a polyether-ester elastomer (PEE-A) film layer laminated to the substrate fabric through a polyether-ester elastomer (PEE-B) binder layer, each of PEE-A and PEE-B including polyalkylene glycol residues, alkyleneglycol residues and dicarboxylic acid residues, in which composite fabric, (1) the PEE-A contains 5 to 25% by mass of polyethyleneglycol residues, (2) the PEE-A film layer is 5 to 5 ?m thick, (3) the PEE-B has a melting temperature of at least 20° C. below that of the PEE-A and (4) the PEE-B binder layer is present in an amount of 2 to 20 g/m2.

  • Patent number: 6716776
    Abstract: A nonwoven fabric made of filaments, which comprises filaments formed from a fiber-forming thermoplastic polymer and satisfies all of the following conditions (A) to (D). (A) The fiber bundles are present in a range of 5-70 per centimeter in any cross-section parallel to the direction of thickness of the nonwoven fabric. (B) The total area occupied by the fiber bundles is in a range of 5-70% of the cross-sectional area of any cross-section perpendicular to the direction of thickness of the nonwoven fabric. (C) The apparent density is 0.10-0.50 g/cm3. (D) The cut ends of the fibers on the nonwoven fabric surface are present in a range of 5-100 per mm2 of surface area.

  • Patent number: 6521552
    Abstract: A water vapor-permeable waterproof fabric free from an environmental pollution problem upon being discarded is formed by coating a substrate fiber fabric with a composite coating layer including a lower layer (A) directly formed on the substrate fabric and an upper layer (B) formed on the lower layer (B), wherein the lower and upper layers are formed from one of polyetherester elastomers different from each other and each containing polyalkylene glycol (PAG) residues, and satisfy the following requirements: (a) in the polyetherester elastomer (PEEA), the polyalkylene glycol residues contain 90% by weight or more of polytetramethylene glycol residues; (b) in the polyetherester elastomer (PEEB), the polyalkylene glycol residues contain 50% by weight or more of polyethylene glycol residues; (c) the thickness of the composite coating layer is 5 to 50 &mgr;m; and (d) the lower layer (A) is in an amount of 5 to 40% by weight based on the total weight of the composite coating layer.
