摘要:
A method of protecting a smooth surfaced substrate by a surface protection film that has improved high temperature peel force properties and low residue upon removal of the surface protection film from the smooth surfaced substrate.
摘要:
A formed film with micro-cells and macro-cells or depressions may be disclosed. For example, the film may include a lands. Each of the lands may include micro-cells thereon. The micro-cells may have a first orientation. The film may further include macro-depressions adjacent to at least one respective land. Each of the macro depressions may include additional second micro-cells. Those additional micro-cells may have a second orientation. The second orientation includes an orientation that is an inverse of the first orientation (e.g., is in an opposite direction of the first orientation).

Composite fabrics comprise a nonwoven web, preferably a fully calendared nonwoven web of fusible fibers, and a monolithic breathable polymer layer on at least one surface of the web and have excellent breathability, good abrasion resistance, and offer protection against both blood and viral agents.
摘要:
Apertured nonwoven webs are disclosed wherein the apertures in the web are treated with an active substance such that the inner surface of the aperture differs in properties, characteristics or appearance from a surface of the web adjacent to the aperture.
摘要:
A tough low set elastic film exhibiting surprisingly high tear resistance and method of making the same. The film of the invention is especially beneficial when holes form on the films during manufacturing or normal wear and method of making. The film has activated (105) and non-activated (106) zones formed during an activation process. The activated zones (105) allow the film to expand without generating excessive tensional forces. The film has M-polypropylene or M-polyethlyene skin layers and a core layer having an elastomeric polyurethane, ethylene copolymer such as ethylene vinyl acetate, an ethylene/propylene copolymer elastomer or ethylene/propylene/diene terpolymer elastomer. The activation process allows the skin layers to behave more like the core layer.
摘要:
A film (14) for use in absorbent articles is first microscopically textured (16) and then macroscopically apertured (18) while maintaining the microscopic texture (16). The micro-texturing (16) may be done by a variety of means including vacuum forming, and may include micro-apertures. The macroscopic texture (18) may be done by a variety of means including thermo-mechanical means with a heat shielding means (22). Where heated pins (20) are used, the heat shielding means (22) protects the micro-texture (16) from the heat so that the heat does not deform the micro-texture (16).
摘要:
Articles and methods related to elastic films exhibiting low tensile force properties in the machine direction. The elastic films have two layers and an elastomeric core layer bonded between the first layer and the second layer Such elastic films have a wide range of potential uses in both durable and disposable articles, but are particularly well suited for use in elastic waistbands, side panels and elsewhere in diapers, training pants and other products including absorbent products.
摘要:
The present invention relates to absorbent articles and non-absorbent articles which comprise at least one improved double-sided soft and elastic material composite 10. The composites 10 according to the invention may also be breathable. The composites are produced by incrementally stretching a laminate of an elastic layer 14 between two non-elastic cloth-like layers 12,16. The non-elastic cloth-like layers tear during stretching such that the elasticity of the laminate 10 after stretching is substantially the same as the elasticity of the film elastic layer 14.
摘要:
A method for forming an elastic laminate comprising: bonding a first nonwoven to an elastic film to form a laminate; activating the laminate to form an activated laminate; and bonding a consolidated nonwoven to the elastic film of the activated laminate to form the elastic laminate.
摘要:
Methods and articles are taught comprising differential energy composites. The composite is a unified structure comprising layers with differing surface energies. A differential between the surface energies exists and access may be provided through one layer to another layer, so that liquids maybe drawn into the composite.
