摘要： There is disclosed a thermally bonded spunbond web of thermoplastic filaments and a nonwoven fabric laminate comprising an internal layer of meltblown thermoplastic microfibers sandwiched between two layers of spunbond thermoplastic filaments. The spunbond web and the spunbond layers of the fabric laminate consist of thermoplastic filaments which are formed from a mixture of a thermoplastic polymer and an effective amount of a nucleating agent. The layers are bonded by thermal spot bonding. In the preferred embodiment, the thermoplastic polymer is polypropylene with a melt-flow rate of at 230 .degree. C. of or greater than 12 grams per ten minutes. Also in the preferred embodiment, the nucleating agent constitutes from about 0.1 to 0.3 percent by weight of the mixture of polypropylene and nucleating agent. The nucleating agents that are useful include dibenzylidene sorbitol, di(methylbenzylidene) sorbitol, bis (p-ethylbenzylidene) sorbitol and hydrophobic, fumed silica having particle sizes up to 1 micron in diameter. The nonwoven laminate is particularly useful in manufacturing work garments and other protective apparel having enhanced durability.

摘要： Nonwoven fibrous elastomeric web material, including absorbent webs and fabric web material, and methods of forming the same, are disclosed. The elastomeric web material is a hydraulically entangled coform or admixture of (1) meltblown fibers, such as elastic meltblown fibers and (2) pulp fibers and/or staple fibers and/or meltblown fibers and/or continuous filaments, with or without particulate material; such coform can be hydraulically entangled by itself or with other materials, including, e.g., super absorbent particulate material. The use of meltblown fibers facilitates the hydraulic entangling, resulting in a high degree of entanglement and enabling the use of shorter staple or pulp fibers. The hydraulic entangling technique provides a nonwoven fibrous elastic material having increased web strength and integrity, and allows for better control of other product attributes, such as absorbency, wet strength and abrasion resistance. A smooth surfaced and/or highly absorbent elastic web material, with isotropic strength and recovery in both machine- and cross-directions, can be provided according to the present invention.

摘要： Nonwoven fibrous non-elastic webs, reinforced nonwoven fibrous non-elastic webs and methods of forming the same are disclosed. The nonwoven fibrous non-elastic webs are a hydraulically entangled coform or admixture of non-elastic meltblown fibers and fibrous material, with or without particulate material. The fibrous material (e.g., non-elastic fibrous material) can be at least one of pulp fibers, staple fibers, meltblown fibers and continuous filaments. The use of meltblown fibers facilitates the hydraulic entangling, resulting in a high degree of entanglement and enabling the more effective use of shorter fibrous material. The hydraulic entangling technique provides a nonwoven fibrous material having increased web strength and allows for better control of other product attributes, such as absorbency, wet strength, printability and abrasion resistance. The coform can be hydraulically entangled with a reinforcing material, e.g., a melt-spun nonwoven, a scrim, screen, net, etc.
