Abstract: A method for attaching chitosan to the surface of polymers that includes at least one rehydration step has been developed to provide more effective and stable chitosan coating. Polymers produced using this method and articles that are made with these polymers provide antibacterial and anti-odor properties.

Abstract: A method is provided to produce antimicrobial thermoplastic polymer blends by blending chitosan acid salts with polymers having amino-reactive functional groups. The antimicrobial thermoplastic polymer blends produced and articles composed of these materials are described.

Abstract: A method for preparing stretchable bonded nonwoven fabrics which involves forming a substantially nonbonded nonwoven web of multiple-component continuous filaments or staple fibers which are capable of developing three-dimensional spiral crimp, activating the spiral crimp by heating substantially nonbonded web under free shrinkage conditions during which the nonwoven remains substantially nonbonded, followed by bonding the crimped nonwoven web using an array of discrete mechanical, chemical, or thermal bonds. Nonwoven fabrics prepared according to the method of the current invention have an improved combination of stretch-recovery properties, textile hand and drape compared to multiple-component nonwoven fabrics known in the art.

Abstract: Provided is a process comprising contacting a spun-bonded polypropylene fabric with a layer of fibers that are not polypropylene, point-bonding the layers together to form a bonded layered fabric, exposing the bonded layered fabric to heat under suitable conditions followed by cooling to form a layered elastomeric fabric, the bonded layered fabric being disposed in a manner to permit free-shrinkage in at least one dimension to occur during at least a portion of the heating, and wherein the point-bonds in the bonded layered fabric comprise 5-60% of the total fabric area. A layered elastomeric fabric produced by the process and textile products made of the layered elastomeric fabric are also provided.

Abstract: The present invention provides for a non-woven fabric composite consisting essentially of a mutually interbonded mixture of crimped isotactic polypropylene fiber segments and uncrimped hard elastic isotactic polypropylene fiber segments. A process to manufacture the non-woven fabric composite and textile goods fabricated from the disclosed non-woven fabric composite are also provided.
