摘要： Improved polypropylene fibers exhibiting greatly reduced heat- and moisture-shrink problems and including certain compounds that quickly and effectively provide rigidity to the target polypropylene fiber after heat-setting are disclosed herein. In such a manner, the “rigidifying” 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 “rigidifying” compounds include dibenzylidene sorbitol based compounds, as well as less preferred compounds, such as sodium beuzoate, certain sodium and lithium phosphate salts (such as sodium 2,2′-methylene-bis-(4,6-di-tert-butylphenyl)phosphate, otherwise known as NA-11).

摘要： This invention relates to improvements in preventing heat- and moisture-shrink problems in specific polypropylene fibers. 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 “rigidifying” 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 “rigidifying” 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 2,2′-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：本发明涉及防止特定聚丙烯纤维中的热收缩和水分收缩问题的改进。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将聚合物晶体成核。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。

摘要： This invention relates to a fluid dispersion of at least one dibenzylidene sorbitol acetal derivative. The sorbitol acetal derivative is useful as a clarifying agent for polyolefins and the inventive fluid dispersion permits improvements in the handling and processing of and mixing within the polyolefin composition. The inventive dispersion must be shelf stable, retain its nucleating effects, be compatible with polypropylene (and other polyolefins), and possess both short-term and long-term viscosities which permit acceptable transport through a standard polyolefin-manufacturing peristaltic pump. The preferred inventive dispersion thus comprises 3,4-DMDBS and at least one ethoxylated nonionic surfactant having an HLB of greater than about 8.5. Preferred surfactants include those selected from the group consisting essentially of ethoxylated sorbitan (C.sub.8 -C.sub.22) monoesters and ethoxylated nonyl-phenol ethers. The inventive dispersion may be introduced within any polyolefin composition, preferably polypropylene, which may then be molded into any shape or form. A method of producing a polyolefin plastic utilizing the inventive dispersion is also provided.

摘要： Thermoplastic articles may be manufactured having a high degree of visual appeal to consumers. Clarifying agents may be employed as additives in such thermoplastic articles to produce high clarity articles. A coloring agent may be mixed with clarifying agents to form a first blend, and then such a first blend may be applied in very low loadings to form a clarified polymeric article. It is possible to achieve an observable visual benefit while using very low loadings of coloring agent in a polyolefin, such as polypropylene. Carbon black is a pigment that may provide such observable benefits in polypropylene.

摘要： A specific combination of two different polyolefin clarifying and nucleating agents, namely 3,4-dimethyldibenzylidene sorbitol and p-methyldibenzylidene sorbitol is provided. Such a combination surprisingly provides improved clarification and crystallization temperatures to polypropylene articles and formulations, better than bis-p-methyldibenzylidene sorbitol alone and equivalent or better than 3,4-dimethyldibenzylidene sorbitol. Such a combination of compounds thus permits the utilization of a new additive for the purpose of modifying polyolefin properties, such as polypropylene clarification and nucleation. The inventive combination may be introduced within any polyolefin composition, again preferably polypropylene, which may then be molded into any shape or form. A method of producing a polyolefin plastic utilizing the inventive combination of compounds is also provided.
