    Abstract: A conformable surfacing veil (20) having an improved soft feel is formed by admixing a thermoplastic sheath-core bicomponent fiber (24) with a regularly or irregularly shaped structural fiber (22) to form a core composition for the mat. The bicomponent fiber is formed from a core material (26) and a sheath material (28). Suitable core material include thermoplastic polymers such as polyethylene terephthalate that have a higher melting point than the sheath like polymer. Suitable sheath materials include polyethylene, polypropylene, and copolyesters having softening points lower than the core material. Thus, when the mixture of structural fibers and bicomponent fibers is heated above the softening point of thesheath materials, the bicomponent fiber will fuse to the structural fibers. The surfacing veils can then be laminated to other reinforcing mats for use as a reinforcement for plastic articles.

    Abstract translation: 通过将热塑性皮芯 - 双芯组分纤维（24）与规则或不规则形状的结构纤维（22）混合形成具有改善的柔软手感的一致的表面面纱（20），以形成垫的芯组合物。 双组分纤维由芯材（26）和护套材料（28）形成。 合适的芯材料包括诸如聚对苯二甲酸乙二醇酯的热塑性聚合物，其具有比鞘状聚合物更高的熔点。 合适的护套材料包括软化点低于芯材料的聚乙烯，聚丙烯和共聚酯。 因此，当将结构纤维和双组分纤维的混合物加热到高于软质材料的软化点时，双组分纤维将融合到结构纤维上。 然后将表面的面纱层压到其他增强垫上，用作塑料制品的增强件。

    Abstract: The present invention relates to absorbent articles, such as diapers and sanitary napkins, and acquisition layers useful for such articles. More specifically, the invention relates to an acquisition layer for an absorbent article, the liquid acquisition layer com-prising a multitude of fibers and a binder, the liquid acquisition layer having a caliper which decreases in response to external pressure and increases upon removal of said external pressure. In accordance with the present invention the increase in caliper is measured by the recovery value as defined herein and the liquid acquisition layer recov-ery value at 45 C is at least 65 % of the recovery value at 20 C.

    Abstract: A process for making an absorbent material involves flash-drying a superabsorbent polymer precursor composition. The process may be used to make a superabsorbent-fiber material without the necessity of mixing conventional superabsorbent solid particles with pulp fluff is provided. The synthesis (i.e., polymerization) of the superabsorbent is completely integrated into the process for forming the absorbent material. One or more streams of superabsorbent polymer precursor composition are provided, to which a plurality of individual fibers may be added. The resulting in-situ polymerized superabsorbent-fiber material is then flash-dried and can subsequently be formed into a superabsorbent-fiber composite. The flash-drying is relatively inexpensive and requires little drying time compared to conventional drying methods.

    Abstract: The present invention is directed to crimped and resilient polymeric fibers and to fabrics and laminates made from the fibers. In general, the fibers are produced by crimping a polymeric fiber and then cross-linking a polymer and/or monomer contained within the fiber. Cross-linking the polymer makes the crimp contained with the fiber more permanent and more resilient. When formed into a nonwoven web, the fibers produce high loft fabrics which are resilient to compressive forces. Nonwoven webs made in accordance with the present invention are particularly well suited for use in filter products and liquid absorbent products.
