    摘要: The invention relates to a lactic acid residue containing polymer composition and product having improved stability and to methods for the preparation and use thereof. The lactic acid residue containing polymer preferably includes a polylactide polymer having a number average molecular weight of between about 25,000 and about 200,000, lactide, if present at all, present in a concentration of less than 0.5 wt % based on the weight of the composition, and deactivating agents. Articles which can be manufactured from the lactic acid residue containing polymer composition include fibers, coated paper, films, moldings, and foam.

    摘要: Multi-component fibers having enhanced reversible thermal properties and methods of manufacturing thereof are described. In one embodiment, a multi-component fiber includes a fiber body formed from a set of elongated members, and at least one of the set of elongated members includes a temperature regulating material having a latent heat of at least 40 J/g and a transition temperature in the range of 22° C. to 40° C. The temperature regulating material provides thermal regulation based on at least one of absorption and release of the latent heat at the transition temperature. The multi-component fiber can be formed via a melt spinning process or a solution spinning process and can be used or incorporated in various products where a thermal regulating property is desired. For example, the multi-component fiber can be used in textiles, apparel, footwear, medical products, containers and packagings, buildings, appliances, and other products.
