摘要： A biodegradable, substantially continuous filament is provided. The filament contains a first component formed from at least one high melting polyester and a second component formed from at least one low melting polyester. The low melting point polyester is an aliphatic-aromatic copolyester formed by melt blending a polymer and an alcohol to initiate an alcoholysis reaction that results in a copolyester having one or more hydroxyalkyl or alkyl terminal groups. By selectively controlling the alcoholysis conditions (e.g., alcohol and copolymer concentrations, catalysts, temperature, etc.), a modified aliphatic-aromatic copolyester may be achieved that has a molecular weight lower than the starting aliphatic-aromatic polymer. Such lower molecular weight polymers also have the combination of a higher melt flow index and lower apparent viscosity, which is useful in the formation of substantially continuous filaments.

摘要： A biodegradable fiber that is formed from a thermoplastic composition that contains polylactic acid, a plasticizer, and a compatibilizer is provided. The compatibilizer includes a polymer that is modified with a polar compound that is compatible with the plasticizer and a non-polar component provided by the polymer backbone that is compatible with polylactic acid. Such functionalized polymers may thus stabilize each of the polymer phases and reduce plasticizer migration. By reducing the plasticizer migration, the composition may remain ductile and soft. Further, addition of the functionalized polymer may also promote improved bonding and initiate crystallization faster than conventional polylactic acid fibers. The polar compound includes an organic acid, an anhydride of an organic acid, an amide of an organic acid, or a combination thereof. Such compounds are believed to be more compatible with the generally acidic nature of the polylactic acid fibers.

摘要： A fiber formed from a thermoplastic composition that contains a thermoplastic starch and an aliphatic-aromatic copolyester is provided. The copolyester enhances the strength of the starch-containing fibers and also facilitates the ability of the starch to be melt processed. Due to its relatively low melting point, the aliphatic-aromatic copolyester may also be extruded with the thermoplastic starch at a temperature that is low enough to avoid substantial removal of the moisture found in the starch. Furthermore, the aliphatic-aromatic copolyester is also modified with an alcohol so that it contains one or more hydroxyalkyl or alkyl terminal groups. By selectively controlling the conditions of the alcoholysis reaction (e.g., alcohol and copolymer concentrations, temperature, etc.), the resulting modified aliphatic-aromatic copolyester may have a molecular weight that is relatively low. Such low molecular weight polymers have the combination of a higher melt flow index and lower apparent viscosity, which is useful in a wide variety of fiber forming applications, such as in the meltblowing of nonwoven webs.
摘要翻译： 提供由含有热塑性淀粉和脂肪族 - 芳香族共聚酯的热塑性组合物形成的纤维。 共聚酯增强了含淀粉纤维的强度，并且促进了淀粉熔融加工的能力。 由于其相对低的熔点，脂肪族 - 芳族共聚酯也可以在足够低的温度下与热塑性淀粉一起挤出，以避免显着除去在淀粉中发现的水分。 此外，脂族 - 芳族共聚酯也用醇改性，使得其含有一个或多个羟烷基或烷基端基。 通过选择性地控制醇解反应的条件（例如醇和共聚物浓度，温度等），所得改性的脂肪族 - 芳族共聚酯的分子量可以相对较低。 这种低分子量聚合物具有较高的熔体流动指数和较低的表观粘度的组合，其可用于各种各样的纤维形成应用中，例如在非织造纤维网的熔喷中。
