  • Method for forming a glove attachment
    Patent number: 5384083
    Abstract: A method for forming a glove attachment principally for the palm of an astronaut glove to enhance the gripping area of the palm without detracting from the flexibility and utility of the glove. The attachment is a composite construction formed from a layer of silicone rubber having an outer surface with a friction configuration and an another layer of silicone rubber in which a meta-aramid mesh fabric is embedded prior to curing. The method of construction involves the use of a mold with a friction configuration surface. A first layer of silicone rubber or sealant is disposed in the mold and allowed to set for an hour. A second layer of silicone rubber or sealant is layered over the first layer and leveled. A meta-aramid mesh fabric is embedded into the second layer and the composite is permitted to cure. When cured, a configured area of the composite construction is glued or stitched to the palm area of the glove.

  • Textile product with backcoating comprising smoke suppressant and/or flame retardant intumescent particles
    Patent number: 4824709
    Abstract: A textile product with enhanced flame and/or smoke retardant properties and a method of forming the same is disclosed. The textile product is comprised of a textile material and a backcoating comprised of a polymer matrix and inorganic smoke suppressant and/or flame retardant intumescent particles. The backcoating may also contain an inorganic filler that further enhances the flame retardancy and low smoke properties of the textile product. The methods of forming this textile product include mixing the smoke suppressant and/or flame retardant intumescent particles with the backcoating prior to its application to the textile material or the simultaneous spreading of the particles on the textile material with the polymer backcoating in order to form a layer of the particles directly adjacent to the textile material.

  • Heat resistant protective hand covering
    Patent number: 4454611
    Abstract: A heat-resistant, protective glove having a shell made of a fabric of a temperature-resistant aromatic polyamide fiber, the outer surface of the shell being coated with a fire-resistant elastomer and a liner, generally conforming and secured to the shell and disposed inwardly of the shell, the liner being made of a felt fabric of a temperature-resistant aromatic polyamide fiber.

  • Heat sealable, flame and abrasion resistant coated fabric
    Patent number: 4395511
    Abstract: Flame retardant, abrasion resistant elastomeric compositions comprised of thermoplastic polyurethane polymer and flame retarding amounts of a filler selected from decabromodiphenyloxide and antimony oxide in a 3:1 weight ratio, and decabromodiphenyloxide, antimony oxide, and ammonium polyphosphate in a 3:1:3 weight ratio respectively. Also, flame retardant, abrasion resistant, and heat sealable coated fabrics employing such elastomeric compositions as coating film.
