摘要： A biodegradable and renewable film that may be employed in a wide variety of applications is provided. The film is formed from a thermoplastic composition that contains at least one starch and at least one plant protein. Even at a high renewable material content, the present inventors have discovered that films may be readily formed from plant proteins and starches by selectively controlling the individual amount of the starch and plant proteins, the nature of the starch and plant proteins, and other components used in the film. Balancing the amount of starches and plant proteins within a certain range, for instance, can reduce the likelihood of plant protein aggregation and enhance the ability of the composition to be melt processed. The composition also contains at least one plasticizer that improves the thermoplastic nature of the protein and starch components. The selection of the plasticizer may also help reduce the tendency of the plant protein to aggregate during melt processing. For example, a relatively acidic plasticizer (e.g., carboxylic acid) may be employed in certain embodiments to minimize the formation of disulfide bonds in a gluten protein, and thereby decrease its tendency to aggregate.

摘要： A method for forming a biodegradable polylactic acid suitable for use in fibers is provided. Specifically, a polylactic acid is melt processed at a controlled water content to initiate a hydrolysis reaction. Without intending to be limited by theory, it is believed that the hydroxyl groups present in water are capable of attacking the ester linkage of polylactic acids, thereby leading to chain scission or “depolymerization” of the polylactic acid molecule into one or more shorter ester chains. The shorter chains may include polylactic acids, as well as minor portions of lactic acid monomers or oligomers, and combinations of any of the foregoing. By selectively controlling the hydrolysis conditions (e.g., moisture and polymer concentrations, temperature, shear rate, etc.), a hydrolytically degraded polylactic acid may be achieved that has a molecular weight lower than the starting polymer. Such lower molecular weight polymers have a higher melt flow rate and lower apparent viscosity, which are useful in a wide variety of fiber forming applications, such as in the meltblowing of nonwoven webs.
摘要翻译：提供一种形成适用于纤维的可生物降解的聚乳酸的方法。具体地说，将聚乳酸以受控的水分进行熔融加工以引发水解反应。不期望受理论的限制，据信存在于水中的羟基能够攻击聚乳酸的酯键，从而导致聚乳酸分子链断裂或“解聚”成一个或多个较短酯链。较短的链可以包括聚乳酸，以及乳酸单体或低聚物的少部分，以及上述任何一种的组合。通过选择性地控制水解条件（例如水分和聚合物浓度，温度，剪切速率等），可以实现分子量低于起始聚合物的水解降解聚乳酸。这种较低分子量的聚合物具有较高的熔体流动速率和较低的表观粘度，其可用于多种纤维形成应用中，例如在非织造纤维网的熔喷中。
