  • Patent number: 5681612
    Abstract: Methods for preparing abrasive articles and novel methods of making abrasive articles are presented. One method includes inserting a fibrous material adjacent an interior surface of a drum. A composition comprising an organic binder precursor material is then placed in the drum, and the drum is rotated such that centrifugal forces distribute the composition, including the organic binder precursor material, uniformly about the fibrous material. The composition is exposed to conditions sufficient to solidify the organic binder precursor material such that an endless, flexible, seamless substrate is formed having an outer surface formed adjacent the interior surface of the drum, an inner surface opposite the outer surface and the fibrous material embedded therein. Coated abrasives formed by this method, as well as other methods, are provided wherein an effective amount of a fibrous reinforcing material is engulfed within an organic polymeric binder material.

  • Patent number: 5312646
    Abstract: Photographic materials, such as films and papers, include a support and coatings on the support. The coatings often contain hardeners which cause gelation cross links in the binder in the coating. The extent to which the cross-links have formed at the time of processing of the film or paper affects the appearance of the image produced by processing. Conventionally the cross-links have been allowed to form with time in normal atmospheric conditions. According to the invention, the formation of the cross links is accelerated to substantial completion by a process including incubating the material at a temperature above the glass transition temperature of the coating and below the melting point of the coating in an atmosphere having a relative humidity which causes a moisture content of the coating of 0.1 to 0.25 for a period of time sufficient to substantially complete the hardening, that is, the formation of the cross-links.

    Abstract: A method for manufacturing a coated textile which exhibits a worn look when stressed. The method includes depositing a water-base resinous coating on the textile wherein the amount of coating placed on the textile is controlled such that the threads are coated but a thin film is not formed thereon. After depositing the coating on the material, the coating is passed through a first heat exchange zone to remove the water and dry the coating. Then the dried coated textile is passed through a second heat exchange zone wherein the temperature is sufficient to fuse the coating to the threads to obtain a clear coating such that when the textile is stressed the coating fractures importing a worn appearance to the stressed area of the textile.

  • Patent number: 4668540
    Abstract: Belting consisting of a compacted non-woven felt fabric embedded in a matrix of elastomer. The belting may be made by saturating a greige non-woven fabric with a liquid, elastomer-forming, polymeric resin and thereafter compacting the saturated fabric to permanently reduce the thickness thereof. Following compaction of the saturated fabric, the liquid resin is solidified and cured. Curing is preferably accomplished at a temperature above ambient and at a pressure above atmospheric. The non-woven felt may be a spun-bonded, needle-punched, or stitch-bonded bat of fibers.

  • Patent number: 4666765
    Abstract: The present invention is directed to method for making silconecoated woven fabric substrates, and the products produced by such method. The method comprises the steps of applying a first liquid polysilicane elastomer to the substrate so as to form a base coat, curing the base coat, applying a second liquid polysilicane elastomer over the base coat so as to form a top coat, and curing the top coat. By specifically selecting the polysilicane elastomers as well as the substrate, and by further selecting the reaction parameters, a high strength, non-flammable, waterproof, self-cleaning, translucent and weather-resistant fabric is produced.

  • Patent number: 4637940
    Abstract: An elastomer coated bias fabric for reinforcing power transmission belts and the like is disclosed wherein one surface of the fabric is provided with an uncured, tacky, elastomeric composition. The fabric is prepared by pre-impregnating the fabric, transversely stretching the fabric on a tenter frame, coating a latex composition on both surfaces of the fabric while maintaining the fabric in its transversely stretched condition, and after drying the fabric, overcoating one surface only of the coated fabric with a tackified, latex composition which may contain a chemical linking agent which enhances the bond between the elastomer and the fabric by forming a chemical bridge between them. A method for manufacturing coated fabric is also disclosed.

  • Patent number: 4618512
    Abstract: Synthetic-cellulosic blended fabric is padded with a solution of nitrogen rich N-methylol crosslinking agent, acid catalyst, antimony oxide and a halogen containing alcohol; dried at about 140.degree.-190.degree. F. and then cured at about 250.degree.-400.degree. F. for sufficient time to impart smooth-dry and flame retardant properties to the fabric. Aqueous polyethylene or silicone emulsion softeners can be added to the padding solution if desired. Dibromoneopentyl glycol makes an exemplary halogen containing alcohol. The process can be varied to first pad with antimony oxide, dry, and then repad with a solution of: nitrogen rich N-methylol crosslinking agent, acid catalyst, and a halogen containing alcohol, dry again and cure, at the above specified temperatures.

  • Patent number: 4574107
    Abstract: A method for producing a coated woven fabric, in which the support material comprises disintegrable chemical weft threads which are subsequently removed without the other threads being affected, method wherein:a first support fabric is produced of which only part of the weft threads are disintegrable, and in a weave in which said disintegrable weft thread is so arranged that, were it to be removed, the result would be, not a woven fabric any longer, but a superposition of three criss-crossed layers of parallel warp threads, one layer of weft threads being squeezed between two layers of warp threads, respectively;then, said support fabric is coated with a coating composition;and finally, the deposited coating is gelled in the right temperature conditions to remove the disintegrable weft thread.
