摘要： A PET nonwoven fabric for a separator for a secondary battery includes first fibers composed of PET having a melting temperature of 240° C. or more and second fibers composed of PET having a melting temperature of 180˜220° C., respective fibers having two types of fibers having different diameters, and has a fine pore size and uniform pore distribution and exhibits superior surface properties, low surface defects, high mechanical strength and excellent mass production. Even when the temperature of a battery is increased to 200° C. or more, the PET nonwoven fabric has heat resistance which prevents thermal runaway and does not generate melting and shrinking.

摘要： Microfiber microwebs are provided. The microfiber microwebs have relatively dense nuclei with individual fibers and/or fiber bundles protruding therefrom. The microfiber microwebs can be incorporated into nonwoven webs of blown microfibers, air-laid staple fibers, or wood pulp fibers as well as into shaped articles having porous covering materials. The microfiber microwebs are useful in sorbent, filtration, and thermal insulation materials. The microfiber microwebs are prepared by divellicating a microfiber web to form discrete particles of microfiber microwebs.

摘要： Particle-laden meltblown material, methods for forming such material, composite laminate fabrics using such material as a layer of the laminate, and uses of such material and/or laminate thereof are disclosed. The particle-laden meltblown material is a coform of the particles and meltblown fibers, consolidated into a meltblown material. The meltblown fibers are made of polymeric materials such that the fibers are tacky after extrusion from the meltblowing die and prior to consolidation as meltblown material; active particles (such as active carbon) are incorporated in the stream of meltblown fibers, as the fibers pass from the die to the consolidation surface, at a location where the fibers are tacky, so that the particles adhere to the surface of the fibers. The polymeric materials forming the meltblown fibers can be elastomeric materials, and/or blends of polymers. The formed meltblown material can be used as a layer of a laminate, with other layers of the laminate providing abrasion resistance and mechanical strength. The meltblown material, and/or laminate including the meltblown material, can be used for gas/vapor filtering and/or adsorbing, and specifically can be used for disposable vacuum cleaner bags and the like.

摘要： The invention generally provides for formation of meltblown material containing wood fiber on to a continuous foraminous belt. During formation a polymer and wood fiber first layer is applied to a moving belt from at least one bank of meltblown forming apparatus. This first layer does not contain superabsorbent. The belt carrying the first layer passes beneath at least one further source of meltblown fiber into which superabsorbent is added along with the wood fibers. This provides at least one additional layer integrally connected to the first-formed layer and having superabsorbent properties. The first layer acts to aid in trapping of any superabsorbent which is not immediately entangled in the meltblown and wood fibers and prevents it passing through the forming belt.

摘要： The present invention provides a layered absorbent structure, the structure having an upper surface and a lower surface. The structure comprises:(a) n webs of fibrous material, n being an integer of two or more. The webs are layered such that there is an uppermost web, a lowermost web, n-2 intermediate webs, and n-1 interfaces of two opposed adjacent contacting surfaces of adjacent webs. Each of the interfaces has a surface area.(b) Absorbent particles forming a discontinuous layer at one or more of the interfaces.The opposed adjacent contacting surfaces at each interface where particles are present are substantially entirely frangibly bonded by fiber entanglement between the contacting surfaces. The particles are immobilized at said interface(s) substantially entirely by fiber entrapment.
