    摘要： A separable tow of elongated polymeric filaments comprises a plurality of distinct sub-tows lightly and individually and separably joined, as by light crimping together along their edges or, if uncrimped, joined by presence of moisture, and capable of being packed into a container and later removed and separated. The filaments are preferably acrylic and have a total fineness of about 300,00-1,500,000 denier and the sub-tows each of which has a total fineness of about 50,000-250,000 denier, with a filament fineness of about 1-2 denier, and each sub-tow has a degree of entanglement of about 10-40 mnull1 as measured by the hook drop test. The separable tow is made of a plurality of sub-tows, after separately drawing the sub-tows and subsequently removably joining the sub-tows into a single tow.

    摘要： A method of converting a plastics material into a yarn in which the plastics material comprises one or more polymers selected from the group consisting of nylon, polyesters, polyethylene, polyvinyl chloride, polyphenylene sulphide, polystyrene. The method comprises heating the material to melt it, pumping the melted material through an extruder to form an extruded filament, and cooling the extruded filament. The cooled filament is passed through a first draw roller assembly while elevating the temperature of the filament. The filament is then heated in a heating zone as it exits the first draw roller assembly and, thereafter, the filament is passed through a second draw roller assembly operating at a different linear speed to the first draw roller assembly. The filament is spooled after exiting the second draw roller assembly.

    摘要： An elasticity-processing method for wet suit fabric pieces is disclosed, by which a wet suit fabric piece laminated with a knitted high-elastic cloth is pressed tightly with two sets of rubber squeeze rollers under different rotation speeds to cause an expansion effect on the fabric piece, separate and destroy the weave circle of the weave of the knitted cloth and produce an elasticity to the whole piece of the fabric. In comparison with the conventional low-elastic and high-modulus wet suit fabric pieces, the fabric pieces made with such a process has a high elasticity and low modulus, and is capable to improve the elasticity of wet suits in professional applications. The wet suits made of such fabric are more fitted, softer and more comfortable.

    摘要： Improved polypropylene fibers exhibiting greatly reduced heat- and moisture-shrink problems are provided. Such fibers require the presence of certain compounds that quickly and effectively provide rigidity to the target polypropylene fiber after heat-setting. 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 upon allowing such a melt 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 nullrigidifyingnull nucleator compounds provide nucleation sites for polypropylene crystal growth. After drawing the nucleated composition into fiber form, the fiber is then exposed to sufficient heat to grow the crystalline network, thus holding the fiber in a desired position. The preferred nullrigidifyingnull compounds include dibenzylidene sorbitol based compounds, as well as less preferred compounds, such as sodium benzoate, certain sodium and lithium phosphate salts (such as sodium 2,2null-methylene-bis-(4,6-di-tert-butylphenyl)phosphate, otherwise known as NA-11). Specific methods of manufacture of such fibers, as well as fabric articles made therefrom, are also encompassed within this invention.

    摘要翻译： 提供了显示出显着降低的热和湿收缩问题的改进的聚丙烯纤维。 这种纤维需要某些化合物的存在，这些化合物在热定型之后快速且有效地为目标聚丙烯纤维提供刚性。 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状聚合物之后和允许这样的熔体冷却时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。 将成核组合物拉制成纤维形式后，然后将纤维暴露于足够的热量以生长结晶网络，从而将纤维保持在所需位置。 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）磷酸酯，也称为NA-11）。 制造这种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。
