摘要： A laminate structure for making a cushioned component for a vehicle interior, such as a seat cushion or head rest, has a high density foam bonded to an interior surface of a seat cover material. After the laminate structure is formed into a desired shape for the cushioned component, it is inserted into a vacuum mold having a mold surface with a shape corresponding with a desired exterior surface shape of the cushioned component. Liquid foam-forming material is injected into the laminate structure within the mold and allowed to cure to form the cushioned component. The high density foam of the laminate structure preferably has a density of at least 4 lbs/ft3 and an air permeability of 5 to 100 ft3/ft2 minute. This high density foam may be created by felting a polyurethane foam.

摘要： A multi-component bedding assembly, including a mattress or futon, is vacuum packaged in an air impermeable bag by drawing a vacuum at the open end of the bag and applying a ram or pushing force against the bedding assembly at the closed end of the bag. The pushing force may be intermittently cycled. The packaged bedding assembly also may be wrapped in a woven polyethylene overwrap and tied with bands before it is inserted into a shipping carton.

摘要： Polyurethane foams formed at above atmospheric pressure conditions using methylene diisocyanate or a specific mixture of polyisocyanate and with a major portion of methylene diisocyanate (MDI) with a specific mixture of polyether and graft polyols produces high density viscoelastic foams with improved hand touch (surface smoothness) that better retain viscoelasticity over time. The foam-forming ingredients are mixed together and foamed at controlled pressures in the range 1.05 to 1.5 bar (absolute), preferably 1.1 to 1.3 bar (absolute).

摘要： A fuel delivery system for a liquid fuel cell particularly useful for portable electronic devices includes (a) a container defining a volume for holding a liquid fuel; (b) a reservoir structure positioned within the volume and into which at least a portion of the liquid fuel wicks and from which said liquid fuel subsequently may be metered, such as by pumping. The reservoir structure is formed from a material with a free rise wick height greater than at least one half of the longest dimension of the reservoir structure. Among materials with such wicking capability are foams, bundled fibers and nonwoven fibers, including particularly felted and unfelted reticulated polyurethane foams. The container may have a generally flat and thin profile, formed as a pouch or envelope with substantially planar top and bottom faces of flexible film material, such that the container holding the reservoir structure and filled with liquid fuel can be bent or shaped.

摘要： Modified or filled rebond polyurethane foam structures having desired plushness and compression without adversely affected tensile strength at a given density as compared to unfilled rebond polyurethane foams are formed from an admixture of shredded or chopped polyurethane foam particles and a finely divided inorganic mineral filler, such as barium sulfate or calcium carbonate or mixtures of these and like mineral fillers, that is further mixed with a substantially non-foam forming liquid prepolymer binder that is free of surfactants in foam-stabilizing amounts. A portion of the polyurethane foam particles, from about 10 to about 60 parts by weight based upon 100 parts by weight, is replaced with filler. For each 100 parts by weight of the combined foam particles and filler, about 10 to about 30 parts by weight of prepolymer is added. After the wetted admixture is compressed to the required density, the prepolymer binder is cured with heat and/or steam. Surprisingly, the resultant filled rebond polyurethane foam structure is more plush and softer than unfilled rebond foam, and the filler is uniformly distributed throughout the cured binder and external to the foam cells of the foam particles.

摘要： In a method for bonding a foam-fabric composite to a molded foam core, particularly suitable for use as an automotive cushion assembly, specific advantageous polymeric MDI-based foams are used to achieve consistently excellent bond strength. In the method, a foam layer is flame laminated to a fabric layer. Then the foam-fabric laminate and an air impervious adhesive film are placed over a mold surface, and the adhesive is drawn against the foam of the foam-fabric laminate and the fabric layer is urged against the mold surface by applied vacuum. The foam core pad is placed adjacent to the adhesive film. The film is heated and diffused into the foam pad and into the foam of the foam-fabric laminate, respectively, and allowed to cure. The foam layer laminated to the fabric is formed as the reaction product of a polyether polyol or a graft polyether polyol with from about 30 to about 60 parts by weight of an MDI or a polymeric MDI/TDI blended isocyanate or mixtures thereof, from about 1.5 to 3.0 parts by weight water as blowing agent, from about 0.05 to about 0.20 parts by weight tin catalyst, from about 0.15 to 0.90 parts by weight amine catalyst and from about 0.5 to about 1.5 parts by weight silicone surfactant, wherein all amounts are based on 100 parts by weight polyol.
