Abstract: Inorganic particulate or whiskers are surface-treated to facilitate receptivity to covalent bonding with a coupling agent. Surface treatment forms reactive groups that enable the inorganic particulate or whiskers to covalently bond to a reactive group of the coupling agent. The coupling agent also contains organofunctional groups, which in some examples may be covalently bonded to a polymer matrix by way of crosslinking or by co-polymerizing the functionalized particulate or whiskers together with polymer precursors. The resulting polymeric materials exhibit markedly improved abrasion resistance as well as other improved properties.

Abstract: The present invention provides a composite nonwoven fabric with a superior combination of extensibility, tensile properties and abrasion resistance. The composite nonwoven fabric (10) comprises at least one layer containing multipolymer fibers, with a plurality of bonds bonding the fibers together to form a coherent extensible nonwoven web (11). This coherent extensible nonwoven web (11) has a Taber surface abrasion value (rubber wheel) of greater than 10 cycles and an elongation at peak load in at least one of the machine direction or the cross-machine direction of at least 70%. A second extensible layer (12) is laminated to this coherent extensible nonwoven web (11).

Abstract: A fabric comprising at least two layers wherein at least one layer is an extensible, bonded non-woven composed of a fiber comprising multiple different polymers such as a fiber comprising isotactic polypropylene, polyethylene and a block or grafted polyolefin copolymer or terpolymer which is at least partially miscible with said polypropylene and polyethylene.

Abstract: The invention provides elastic fabrics which are substantially non-extensible in the machine direction and have substantial elastic properties in the cross-machine direction. The process stable fabrics of the invention include a net and a fibrous layer which are secured together. The net is composed of a plurality of continuous machine direction strands and a plurality of cross-direction strands. The machine direction strands are substantially non-extensible and the cross-direction strands are substantially elastic. The fabrics of the invention can be manufactured and processed more readily than fabrics which are elastic in both the machine direction and the cross-machine direction.

Abstract: The invention provides elastic fabrics which exhibit low extensibility in the machine direction and have substantial elastic properties in the cross-machine direction. The fabrics of the invention include an elastic layer and a fibrous layer which are combined together. The fibrous layer is composed of a plurality of thermally activated binder fibers or filaments oriented substantially in the machine-direction of the fibrous web. The fabrics of the invention can be manufactured and processed more readily than fabrics which are elastic in both the machine direction and the cross-machine direction.

Abstract: The invention provides composite elastic nonwoven fabrics and the process of making them. The composite elastic fabrics of the invention include an elastomeric net and at least one fibrous web including binder fibers and which is intimately hydroentangled with the elastomeric net. At least a portion of the binder fibers in the hydroentangled fibrous web have been thermally activated thereby bonding the hydro-entangled web into a coherent, substantially unitary structure encompassing the elastomeric net.

Abstract: An antimicrobially active, non-woven web, a wet wiper containing the web, and a method of making the web. The method includes the steps of forming an unbounded fibrous web; applying throughout the unbonded fibrous web an uncured binder and polyhexamethylene biguanide hydrochloride as an antimicrobial agent, the antimicrobial active agent being substantive to the fibers of the web and to the binder; and curing the binder material to bind the fibers together to form an antimicrobially active, non-woven web.

Abstract: A nonwoven fibrous web is disclosed having high wet tensile strength when packed in a preservative liquid load, yet which breaks up under mild agitation conditions in a wet environment such as by the flushing action of a toilet. The wiper includes a nonwoven web made of a special blend of cellulosic fibers held together only by friction and naturally occurring hydrogen bonding. No binder is necessary to hold together the fibers. Derivatization of the fibers is not necessary for their breakapartability. The nonwoven fibrous web is produced by subjecting a wet-laid web of cellulosic fibers to hydroentanglement and drying the web without addition of a bonding agent.
