Abstract: The present invention provides a nonwoven web prepared from an aliphatic polyester polymer which has sufficient tear strength and is biodegradable. Biodegradable nonwoven webs of the present are prepared from a polymer blend having from about 65% by weight to about 99% by weight of a biodegradable aliphatic polyester polymer and from about 1% by weight to about 35% by weight of a second polymer selected from the group consisting of a polymer having a lower melting point than the biodegradable aliphatic polyester polymer, a polymer having a lower molecular weight than the biodegradable aliphatic polyester polymer and mixtures thereof. Surprisingly, the nonwoven webs of the present invention have a tear strength greater than the tear strength of a nonwoven web prepared from the biodegradable aliphatic polyester polymer alone.

Abstract: A disposable intralabial urinary incontinence article having a resilient and liquid impermeable exostructure captures bodily exudates. The exostructure has a top surface and an internal space adapted to receive fluids. At least a portion of the exostructure is a flange that rests at least partially outside the labia. The exostructure also has a neck extending from the top surface that at least partially occupies the vestibular region and rests proximate the vestibule floor. The neck has a fluid receiving opening which is in communication with the internal space. The neck is configured so the fluid receiving opening is positioned generally adjacent the urethral meatus to direct urine into the internal space. The internal space may include an absorbent and the article may include a clitoral guide to aid positioning of the article within the vestibule.

Abstract: The present invention provides a nonwoven web or laminate having at least one surface with abrasion resistance and a low degree of free fibers on the surface. Also provided is a lofty nonwoven web laminate from multicomponent fibers having at least one surface with improved abrasion resistance and reduced fuzziness over other multicomponent fiber nonwoven webs. This nonwoven webs and laminate can be used where nonwoven webs and laminates are currently used, but are particularly suitable as a filter media. Also described is a method for producing a nonwoven web having at least one abrasion resistant surface. The process includes using a liner material between the forming surface and the forming nonwoven web, wherein the liner is removed after the nonwoven web is bonded. Removing the liner exposes the abrasion resistant surface of the nonwoven web or laminate.

Abstract: A void volume indicator, a packaging system, and a method of consumer product selection are disclosed. The void volume indicator can have either a primary wetness indicator, a secondary wetness indicator, or both that corresponds to a portion of a package having either a primary capacity indicator, a secondary capacity indicator, or both. After using the void volume indicator, feedback from the indicator can be used to select an absorbent article having an appropriate absorbent capacity for the person's needs.

Abstract: A thermoplastic polymer electret material comprising a porous substrate of a blend of a first thermoplastic polymer, such as a polyolefin or polyamide, and from 0.1% to about 25% by weight, of a compatible telomer. The porous substrate is electrostatically charge and is well suited for use in filter media, sterilization wraps, face masks, dust wipes and the like.
