摘要： A disposable absorbent pant having an enhanced belted or balloon-type structure is disclosed. The belt structure may be formed of stretch laminate material, including laterally pre-strained elastomeric material sandwiched between inner and outer layers of nonwoven web material. The belt structure may include one or more unelasticized zones, in which the elastomeric material is omitted, removed or deactivated. As a result, lateral gathers or ruffles of the inner and outer layers, otherwise resulting from elastic contraction of the pre-strained elastomeric material, are substantially reduced in size and/or frequency, or eliminated, within the unelasticized zones. The laminate in the unelasticized zone(s) will thus have relatively lower z-direction thickness and will lie more closely against the wearer's skin. When unelasticized zone(s) are located proximate the sides/hip areas of the product, for example, this effect may provide the product with a more tailored profile and enhance its discreetness when worn beneath outer clothing.

摘要： A process for forming a high loft, nonwoven web is disclosed. The process includes introducing a single molten polymer to a die having a plurality of nozzles. Emitting the molten polymer through the nozzles to form a plurality of filaments. Using air streams to facilitate movement and drawing of the filaments. Directing the filaments, which are transformed into fibers, towards a pair of heated moving surfaces. The pair of heated moving surfaces forming a convergent passage having an entry and an exit. Depositing the fibers into the entry of the convergent passage and routing the fibers between the pair of heated moving surfaces in a machine direction to form a high loft, non-woven web. The web having a fiber size distribution of from 0 μm to about 15 μm with at least about 25% of the fibers being above 4 μm.

摘要： The present invention provides a nonwoven fabric sheet for use in extraction filters having high sealing strength and extraction filters manufactured using the nonwoven fabric sheet. The nonwoven fabric sheet includes a first layer including a spunbonded nonwoven fabric formed from a polyester-based resin having an IV value of 0.60 to 1.00, a crystallinity of 30% to 80%, a crystalline orientation of 60% to 95%, and a birefringence (Δn) of 0.040 to 0.100 and provided with a partial thermocompression bonding section whose thermocompression bonding area rate is in the range of 5% to 30%, and a second layer including a meltblown nonwoven fabric formed from a polyester-based resin blown onto a surface of the first layer and solidified to have a crystallinity of 0% to 14%. The extraction filters are formed by sealing by welding the nonwoven fabric sheet with the second layer of the sheet placed inside.
