    摘要： The invention provides a process for producing a highly absorbent, high strength wiper, which includes the steps of providing a bonded nonwoven web selected from the group consisting of spunbond fiber webs and staple fiber webs, stretching the nonwoven web by applying a stretching tension in at least one direction, aperturing the nonwoven web while maintaining the stretching tension, and relaxing the apertured web, thereby returning the apertured nonwoven web substantially to its pre-stretched dimensions, wherein the process is conducted at a temperature below the softening point of the nonwoven web. The invention also provides a nonwoven wiper produced in accordance with the production process.

    摘要： There is provided a method of softening a nonwoven web by wetting a nonwoven web having a starting, unstretched width and a starting cup crush value, with an aqueous solution of softening chemicals, necking the saturated nonwoven web, drying the nonwoven web at a temperature and time sufficient to remove at least 95 percent of the moisture from the nonwoven web, wherein the web has a final cup crush value which is less than 50 percent of the starting cup crush value. The method may optionally include the step of un-necking the nonwoven web to about between 80 and 125 percent of its starting, unstretched width.

    摘要： A breathable barrier which includes:A. a first layer which is a porous sheet having a first side and a second side; andB. a second layer joined to the first side of the first layer, which second layer is a continuous film of a polymeric latex material, in which:the film is not microporous in that it is substantially free of voids which connect the two surfaces of the film; andthe film has an average thickness of from about 10 to about 250 microns;wherein the first layer side of the second layer is intimately comingled with at least some of the fibers at the surface of the first side of the first layer, none of the pores at the surface of the first side of the first layer are so large as to significantly adversely affect the barrier properties of the breathable barrier as a consequence of the comingling, and the breathable barrier has a water vapor transmission rate at 37.degree. C. and about 50 percent relative humidity of from about 100 to about 2,200 g/m.sup.2 /24 hours and is impermeable to 0.9 percent by weight saline solution at about 21.degree. C. for a period of at least about one hour at a hydrostatic head of at least about 11.4 cm.In place of a coating, the continuous film can be a preformed film of a water-soluble polymeric material which is laminated to the porous sheet. In preferred embodiments, the porous sheet is a meltblown nonwoven web. The disclosed breathable barrier is especially useful as outer covers and baffles in such disposable absorbent articles as diapers, sanitary napkins, and incontinent pads. The breathable barrier also can be used in more durable or protective type applications including garments such as rainwear.
