Dimensionally stable, breathable, stretch-thinned, elastic films

A method for producing a stretch-thinned elastic article having dimensional stability over time and at elevated temperatures in which a thermoplastic block copolymer is melt-processed into a stretchable article such as a film or fiber. The article is then conditioned at an elevated temperature greater than or equal to a glass transition temperature (Tg) of a hard phase of the thermoplastic block copolymer. The article is stretch-thinned at the elevated temperature to a desired percentage stretch, forming a stretch-thinned article, after which it is cooled to a temperature below the glass transition temperature of the hard phase of the thermoplastic block copolymer. Films produced by this method are suitable for use in durable and disposable articles including personal care articles such as diapers, incontinence wear, training pants, and feminine care articles, as well as wound dressings, wipes, towels, napkins, and protective apparel.

Nonwoven webs having reduced lint and slough

Nonwoven webs having reduced levels of lint and slough are disclosed. In accordance with the present invention, the nonwoven webs are treated on at least one surface with a small amount of a polymeric component. The polymeric component may be present, for instance, in the form of meltblown fibers. The meltblown fibers are made from a polymer that is compatible with the nonwoven web. By adding relatively small amounts of meltblown fibers to at least one side of the nonwoven material, lint and slough levels have been found to be significantly reduced. The nonwoven web may be any web containing pulp fibers, such as a tissue web or a coform web.
