摘要： Breathable microporous films are provided having controlled regional breathability with thick high WVTR regions and thinner low WVTR regions. The zoned breathable microporous films can be made by selectively applying heat and/or pressure to specific regions the microporous film such as by feeding a microporous film through a pair of heated nip rollers with one of the rolls having a raised surface area or by applying a focused stream of hot air. Monolayer microporous films and multilayer films having at least one microporous layer can be treated to impart zoned breathability to the film.

摘要： A composite material adapted for barrier garment applications is made by laminating a film with an amorphous polymer layer to a prebonded nonwoven web under conditions producing laminate bonds corresponding to the prebond locations, and unbonded areas between the bonds while maintaining constant film thickness. The composite has enhanced resistance to viral penetration for use as a surgical gown material, for example, and also desirably has a MVTR of at least about 300 g/m2/24 hours and a hydrohead of at least about 50 mbar. In use as a component of a protective apparel such as a surgical gown or drape, the composite provides comfort and protection with reduced risk of film damage.

摘要： A breathable multilayer film including a breathable core layer and one or two skin layers is prepared by providing a core layer mixture of a thermoplastic polymer and a particulate filler, providing a skin layer mixture of at least two incompatible polymers, coextruding the core and skin layer mixtures to form a multilayer film, and stretching the multilayer film to cause void formation in the core layer and crack formation in the one or two skin layers. By forming cracks in the skin layers during stretching, the skin layers can perform dual functions of alleviating die build-up of filler from the core layer during coextrusion, and bonding the film to a substrate subsequent to coextrusion, without unduly hindering the moisture vapor transmission rate of the film or laminate product. The breathable film, and laminates including the film, are useful in a wide variety of personal care absorbent articles, medical garments, and other products.

摘要： A blown film process for producing low gauge, latent elastic films with high cross-direction orientation includes preferentially regulating the temperature gradient of the film along the expansion length. The regulation of temperature along the bubble profile allows more effective “down gauging” of the film and improved melt strength of the hot film. The choice of raw materials is an important element in producing cross-direction-oriented, low gauge, latent elastic films. The method of this invention can be carried out as either a multiple-bubble process or a single-bubble process.

摘要： Transversely stretchable elastic laminated fabric with cloth-like facings was made by a two-step process. In the first step an inelastic laminate was made by continuously extruding an elastomer sheet between two plies of a fibrous sheet and joining the plies by applying pressure on them between a closed gap niproll assembly. Two longitudinal slits were made into the laminate. Then the rolls of inelastic laminate so made were taken to an oven and the laminate was unwound and pulled through the oven at an elevated temperature, while tension on the web was increased until the slits necked. The necked laminate was wound up on a takeup roll. When samples were unwound, surprisingly they did not grow in width, and they showed good CD-elasticity (elongation and springback). Breathability of the laminate was superior to the laminate formed using an open niproll assembly gap.
