  • Publication number: 20220241619
    Abstract: A breathing system hood assembly that fits over a user's head includes an air impermeable hood having an opening dimensioned to fit over the user's head and an elastically deformable neck seal arranged along at least a portion of the opening. The neck seal includes a region wherein the neck seal is arranged in overlapping relation with itself, whereby the neck seal can expand to fit over a user's head and contract to create a seal with the user's neck.

  • Patent number: 8069587
    Abstract: A shoe footbed 10 made by first molding a shape-retaining layer 12 into a contoured condition. After the shape-retaining layer 12 has been molded, a layer of thermal insulation 14 is placed on top of the molded layer 12. A conforming layer 16 and a fabric top layer 18 may be placed over the thermal insulation 14 and the shape-retaining layer 12. The inventive method of manufacture is particularly suited for making insulated footbeds that contain nonwoven webs of polymeric microfiber because damage to the fibrous web from heat and compression may be avoided.

  • Patent number: 5766387
    Abstract: A barrier fabric laminate for use as a coating for a gel filled article is provided. The barrier fabric laminate comprises a fluid impermeable film and a polyurethane nonwoven web which has a friction value of less than 200 g and a fabric hand of less than 200 g. The polyurethane web is formed of fibers of less than about 50 .mu.m on average and preferably is formed with a fluorochemical melt additive by sequentially melt blowing the polyurethane web on a heated collecting drum and laminated by a nip formed by a heated nip roller and the collecting drum.

  • Patent number: 5593769
    Abstract: A barrier fabric laminate for use as a cover for a gel filled article is provided. The barrier fabric laminate comprises a fluid impermeable film and a polyurethane nonwoven web which has a friction value of less than 200 g and a fabric hand of less than 200 g. The polyurethane web is formed from fibers of less than about 50 .mu.m diameter on average and is preferably formed with a fluorochemical melt additive by sequentially melt blowing the polyurethane web on a heated collecting drum and laminating in the nip formed by a heated nip roller and the collecting drum.
