Abstract: A process for chemically bonding an odor-encapsulating agent to textiles includes reacting a cyclodextrin with a cross-linking agent capable of forming ether bonds with the cyclodextrin and with the textile material, and curing the textile material treated with a mixture of the cyclodextrin and cross-linking agent. Preferably, the cross-linking agent is imidazolidone, which forms an ether bond with a hydroxyl group on the cyclodextrin and with a hydroxyl group. In textile materials containing cellulose, imidazolidone forms an ether bond with a hydroxyl group on the cellulose. An active agent can be complexed with the cyclodextrin for release. Textiles formed by such a process can comprise an article of clothing adapted to trap odors emanating from a wearer.

Abstract: In a massy three-dimensional sheet patterning machine having a patterning device with cooperative components for positioning on opposite, front and back sides of a sheet and moving devices for respectively moving the cooperative components cooperatively, the improvements wherein the moving devices each include for the moving a belt having teeth complementary to grooves in at least a driving pulley for the belt.

Abstract: A mechanism is disclosed for driving a puller wheel to assist in feeding cloth material through a sewing machine. The material passes between a puller wheel and an idler wheel after having been sewn by a reciprocating needle. The driven puller wheel assists the standard feed dogs in feeding the material past the needle. The invention discloses a positive drive mechanism having a variable speed gearbox driven by the sewing machine motor and drivingly connected to the puller wheel. The distance between puller wheel and idler wheel is variable to accommodate any thickness of material and still provide a positive feed.

Abstract: Textile size compositions which are dispersible in water and comprise an alkali metal and/or ammonium salt of a styrene-maleic anhydride copolymer containing as a copolymerized component a diester of an olefinically unsaturated dicarboxylic acid or anhydride and a monohydric alcohol and/or a polyester of such an acid or anhydride and a polyhydric alcohol. Also, textile size compositions which are dispersible in water and comprise a mixed salt of a styrene-maleic anhydride copolymer, wherein 20 to 80 weight percent of the cations of said salt are ammonium cations and 20 to 80 weight percent of the cations of said salt are alkali metal cations. Methods for sizing yarns and yarn sized with the above-mentioned compositions.
