  • Patent number: 3998986
    Abstract: Mechanical goods made of rubber-like material, such as belts, hose, and the like, are reinforced with stitch-bonded web fabric.This invention relates to mechanical goods made of rubber-like material reinforced with a stitch-bonded web fabric.Mechanical rubber goods such as conveyor belts, hose, power transmission belts including V-belts and timing belts, snowmobile tracks, and the like, require reinforcement to achieve sufficient strength, rigidity, dimensional stability, and durability. Classically such mechanical rubber goods have been reinforced with various types of woven fabrics, mostly plain woven. More recently attempts have been made to use non-woven or scrim fabric but these generally increase the performance of one property at the expense of another. This is also true when it is attempted to use felts or spray-bonded fabric. Examples of prior disclosures of the use of non-woven fabric in rubber goods are U.S. Pat. No. 3,312,584, Charlton et al., Apr.

  • Patent number: 3991030
    Abstract: The viscosity of a solution of graft copolymer resulting from solution graft copolymerization is greatly reduced, and the handling characteristics are improved, by adding water and a suspending agent to the solution to form a suspension. E.g., to a reaction solution resulting from grafting of styrene and acrylonitrile on EPDM in solution, there is added 20 parts water and 0.1 part polyvinyl alcohol, and the mixture is agitated to produce a low-viscosity suspension.
