Abstract: Disclosed are improved styrene-butadiene (SBR) core-alkyl acrylate/methacrylate shell-polymer compositions and an improved process for applying patterns to textiles by screen printing employing these polymer compositions as binders. The process for preparing the improved polymers is also set forth. The core comprises an SBR copolymer which contains an antioxidant and is at least partially encased by an integral shell of a copolymer of an alkyl acrylate or methacrylate which is formed by copolymerization with an ultraviolet light stabilizer. When used as binders for screen printing, these compositions produce textiles which exhibit a desirable combination of crock fastness, cyclic aging and hand properties.

Abstract: An improvement in the apparatus for the production of air laid fiberglass mat is provided. Fiberglass strands from bobbins, rovings or other sources are fed into a chopper assembly for chopping into smaller in length strands. The smaller in length strands then drop by gravity from the chopper assembly and are picked up by an air stream created by a fan or blower located below the chopper assembly. This air stream directs these smaller in length strands into the inlet of the fan or blower. In an alternative, already chopped strands could be fed directly into the inlet of the fan or blower eliminating the need for the chopper assembly. Fan or blower blades then work on these smaller in length fiberglass strands as they pass from the inlet to the exit of the fan or blower to open or fluff said smaller in length fiberglass strands into partially opened strands. The partially opened strands are then directed by the air stream caused by the air stream caused by the fan or blower through an expanding duct.

Abstract: A carboxylated latex is added to an aqueous slurry of fibers to remove metal ions contained in solution. The water is removed to form a felt. The demetallized water removed during felt formation is recycled in a closed process water system. The carboxylated latex is formed by polymerizing an unsaturated carboxylic acid on a substantially surfactant free styrene-diene polymer latex.
