  • Patent number: 4565744
    Abstract: Metal matrix composite materials are formed from a reinforcing, submicron-particle material, such as SiC, which is not easily wettable by a matrix metal, such as Al, and therefore cannot be uniformly dispersed in the matrix because the particles agglomerate. A coating 12 of material, such as Si, easily wettable by the matrix metal, is placed on the surface of the particles 10 before mixing the reinforcing particles in the matrix metal.

  • Patent number: 4559243
    Abstract: The present invention provides for an absorbent planar structure or so-called "sponge cloth" as well as for the method of making such a structure. The absorbent planar structure itself is permeated with pores and comprises a latex-bonded fiber material optionally reinforced with a woven or knit material, a layer of known foamed plastic, non-woven fabric or abrasive fleece. The method for making such a structure dispenses with conventional pore formers and is characterized by forming a foam of the latex and fiber materials by use of a suitable gaseous medium. The foam thus obtained, after homogeneous mixing, is applied to a substrate and the fiber-containing latex foam is then coagulated by heat action, resulting in an open-pore structure which is stabilized by subsequent drying and vulcanization.

    Abstract: Conventional heat stretching and/or setting conditions for fabrics made of heat sensitive thermoplastic yarns such as polyester, and even special techniques advanced in prior patents, have been found in adequate to produce coated abrasives with sufficient elongation resistance for some very heavy duty service. A superior alternative is provided by encasing the yarns in the backing in a thermosetting adhesive and then curing it while mechanically restraining the yarns from shrinking, as they would under the temperature conditions employed for cure if no restraint were used. The method is also applicable to other types of yarn reinforced web materials for which a combination of elongation resistance and flexibility is needed.

  • Patent number: 4288212
    Abstract: A method and apparatus for fixing the binding agent of a dye-stuff to a printed web of material by means of heat applied to the web within a treatment or polymerization chamber. The treatment time of the web is increased by effecting a loop formation of the web upon a slowly moving belt traveling within the treatment chamber. After the web is first introduced into the chamber, it is then heated. Thereafter, the loop formation takes place. Upon leaving the treatment chamber, the web is passed over a stationary, curved shape heated plate, which smooths the web.

  • Patent number: 4264645
    Abstract: The present invention is concerned with a method for improving the water storage capacity of textile substrates, particularly fleece based artificial leathers by treatment with a hydrophilizing agent. This agent, once applied to the substrate is insoluble in but swellable in water. The agent in an uncross-linked state is water soluble and has a turbidity point of between about 25.degree. and 95.degree. C. in a 25% aqueous solution. The agent may be applied to the substrate from aqueous solution and then cross-linked or it may be applied to an inert carrier such as kaolin, cross-linked and applied to the substrate from an aqueous suspension. A particularly suitable agent is a polyether with a molecular weight of between 500 and 8500, an ethylene oxide content of about 35 to 80 wt. % and cross-linkable end groups. The end groups may be self cross-linking such as vinyl groups or they may be cross-linkable via a cross-linking promoter such as hexamethylol melamine.

  • Patent number: 4246311
    Abstract: A wall covering composed of a base sheet of non-woven polyester material saturated to give it strength, fire retardancy, and opacity and further provides the material with a density that prevents the coating applied to the back from seaping through the sheet. The base sheet is coated on the back to give it greater opacity and make it fungus and mildew resistant. The back coating may also control the thickness as well as the softness or firmness of the sheet. The front surface of the sheet is then transfer printed with the particular design desired.

  • Patent number: 4205559
    Abstract: An improved coating composition, coated reinforcement fabrics, reinforced rubber-based substrate products, and methods of manufacture thereof are disclosed. The coating composition comprises a carboxylated neoprene latex containing an aqueous dispersion of a copolymer of chloroprene and methacrylic acid, polyvinyl chloride as a colloidal stabilizer, and a high boiling oil derived largely from aromatic petroleum feedstocks through a distillation range of between about 195.degree. C. through 325.degree. C. The composition is highly stable, has a long shelf life, and is particularly suited for precoating textile reinforcement fabrics to provide a highly tacky uncured coating surface thereon having exceptionally long high tack in uncured, or green, state. The fabric is employed as a reinforcement layer or cover in rubber-based industrial products, such as power transmission belts, and may be applied in intimate physical adhesion therewith for subsequent vulcanization bonding thereto, as in a vulcanizing mold.
