  • Patent number: 6638636
    Abstract: A breathable multilayer film having a breathable core layer and at least one skin layer is disclosed. The core layer prepared by from a mixture containing a thermoplastic polymer and a particulate filler and the skin layer or layers are prepared from a mixture of at least two incompatible polymers and a polymer which compatiblizes the incompatible polymers. The addition of the compatiblizer in the skin layer improves the film forming consistency. In addition, the core layer contains voids around the particulate filler and the skin layer or layer has cracks or voids, which provides breathability to the multilayer film. Stretching of the film after the layers are coextruded together forms the voids and/or cracks.

  • Patent number: 6613704
    Abstract: Nonwoven webs of continuous filaments are provided having a mixture or blend of first and second continuous filaments wherein the first and second continuous filaments are different from the first continuous filaments in one or more respects such as size, cross-sectional shape, polymer composition, crimp level, wettability, liquid repellency, and charge retention. The second continuous filaments can be substantially surrounded by the first continuous filaments wherein the ratio of first continuous filaments to second continuous filaments exceeds about 2:1.

  • Patent number: 6473910
    Abstract: A durable, single or multi-use cooling garment is provided having a multilayer structure. The cooling garment includes an inner layer of a thermoplastic polymer material that is liquid impermeable and vapor permeable, an outer liquid permeable reinforcing layer such as a web of thermoplastic polymer fibers, and a central absorbent layer that contains a stabilized matrix of about 55% to 95% cellulosic fibers and from about 5% to 45% thermoplastic polymer fibers. The layers are bonded together and the absorbent layer is bonded to at least one of the other layers by regionally applying sufficient energy to the layers wherein the thermoplastic polymers melt and resolidify to form inter-fiber bonds. The cooling garment can be saturated with water or other liquids and provide the wearer with relief from the heat such as may be achieved by evaporative cooling.

  • Patent number: 6274238
    Abstract: The present invention provides a high strength autogenously bonded nonwoven fabric containing single polymer conjugate fibers which have at least two substantially the same component compositions, wherein the component compositions of the fibers contain one thermoplastic polymer selected from the group consisting of semicrystalline thermoplastic polymers, crystalline thermoplastic polymers and blends thereof. The component compositions are processed with substantially identical processing conditions to form the fibers and have substantially the same melt flow rate as measured in accordance with the ASTM 1238-65T testing procedure.

  • Patent number: 6268302
    Abstract: A spunbond nonwoven fabric is provided which has superior strength characteristics to conventional fabrics yet is comparably soft. The fabric is a laminate having a web made from a high melt flow rate polyolefin polymer and a low melt flow rate polymer. The spunbond laminate fabric of this invention may have therebetween a layer of meltblown nonwoven fabric or film. The laminate produced according to this invention has a strength which is at least 10% greater than a comparable fabric made without the high melt flow rate polymer web. The nonwoven fabric of this invention may be used in products such as, for example, garments, personal care products, medical products, protective covers and outdoor fabrics.
