摘要： Improvements in preventing heat- and moisture-shrink problems in specific polypropylene tape fibers are provided. Such tape fibers are basically manufactured through the initial production of polypropylene films or tubes which are then slit into very thin, though flat (and having very high cross sectional aspect ratios) tape fibers thereafter. These inventive tape fibers (and thus the initial films and/or tubes) require the presence of relatively high amounts of certain compounds that quickly and effectively provide rigidity to the target polypropylene tape fiber. Generally, these compounds include any structure that nucleates polymer crystals within the target polypropylene after exposure to sufficient heat to melt the initial pelletized polymer and allowing such an oriented polymer to cool. The compounds must nucleate polymer crystals at a higher temperature than the target polypropylene without the nucleating agent during cooling. In such a manner, the “rigidifying” nucleator compounds provide nucleation sites for polypropylene crystal growth. Subsequent to slitting the initial film and/or tube, the fiber is then exposed to sufficient heat to grow the crystalline network, thus holding the fiber in a desired position. The preferred “rigidifying” compounds include dibenzylidene sorbitol based compounds, as well as less preferred compounds, such as [2.2.1]heptane-bicyclodicarboxylic acid, otherwise known as HPN-68, sodium benzoate, certain sodium and lithium phosphate salts [such as sodium 2,2′-methylene-bis-(4,6-di-tert-butylphenyl)phosphate, otherwise known as NA-11]. Specific methods of manufacture of such inventive tape fibers, as well as fabric articles made therefrom, are also encompassed within this invention.
摘要翻译：提供了防止特定聚丙烯带纤维中的热收缩和水分收缩问题的改进。这种带状纤维基本上通过初始生产聚丙烯膜或管制成，然后将其切割成非常薄的（但具有非常高的截面长宽比）的带状纤维。这些本发明的带状纤维（和因此初始膜和/或管）需要相对高量的某些化合物的存在，其快速且有效地为目标聚丙烯带纤维提供刚性。通常，这些化合物包括在暴露于足够的热量以熔化初始颗粒聚合物并允许这种取向聚合物冷却之后使目标聚丙烯中的聚合物晶体成核的任何结构。在冷却期间，化合物必须在比没有成核剂的目标聚丙烯更高的温度下使聚合物晶体成核。以这种方式，“硬化”成核剂化合物提供聚丙烯晶体生长的成核位点。在切割初始膜和/或管之后，然后将纤维暴露于足够的热量以生长结晶网络，从而将纤维保持在期望的位置。优选的“硬化”化合物包括二亚苄基山梨醇基化合物，以及较不优选的化合物，例如[2.2.1]庚烷 - 双环二羧酸，另外称为HPN-68，苯甲酸钠，某些钠和磷酸锂盐[例如 2,2'-亚甲基 - 双 - （4,6-二叔丁基苯基）磷酸钠，另外称为NA-11]。制造这种本发明的带状纤维的具体方法以及由其制成的织物制品也包括在本发明内。

摘要： An auxetic polymeric material is manufactured in a filamentary or fibrous form. The auxetic polymeric material has a negative Poisson ratio so that it has the property of expanding or contracting transversely to a direction in which it is extended or compressed. The process for forming the material involves cohering and extruding heated polymer powder so that the cohesion and extrusion is effected with spinning to produce auxetic filaments. Typically, the power is heated to a temperature sufficient to allow some degree of surface melting yet not high enough to enable bulk melting.

摘要： A fiber which includes a thermoplastic polymer and particles of a ferroelectric material dispersed therein. The thermoplastic polymer may be, for example, a polyolefin, such as polypropylene or polyethylene, and the ferroelectric material may be barium titanate. The ferroelectric material may be present at a level of from about 0.01 to about 50 percent by weight (from about 0.001 to about 13 percent by volume), and will have a longest dimension in a range of from about 10 nanometers to about 10 micrometers. The fiber may be exposed to an electric field. A plurality of the fibers may be employed to form a knitted or woven fabric or a nonwoven web. Also provided is a method of preparing fibers containing particles of a ferroelectric material. The method includes destructuring the ferroelectric material in the presence of a liquid and a surfactant to give destructured particles; the liquid is a solvent for the surfactant and the surfactant is adapted to stabilize the destructured particles against agglomeration. A blend of the stabilized, destructured ferroelectric material particles and a thermoplastic polymer then is formed and extruded to form fibers. The extruded fibers may be collected on a moving foraminous support to form a nonwoven web and, if desired, may be exposed to an electric field. The fiber of the present invention, especially when in the form of a nonwoven web, is especially suited as a filtration medium. For example, the nonwoven web may be adapted to remove particulate matter from a gaseous stream.
