    • The invention provides a drawn and/or crimped fiber comprising a biodegradable polymer, such as polylactic acid, wherein the drawn and/or crimped fiber exhibits a storage-stable tenacity that does not decrease from an initial tenacity upon manufacture by more than about 10% after storage for 120 days in ambient conditions. The polymer composition used to form the fiber may comprise a softening agent. The fiber can be a drawn and crimped bicomponent fiber that is helically self-crimped and which comprises a first biodegradable polymer component and a second biodegradable polymer component, wherein the first polymer component and the second polymer component exhibit different polymer morphology such that each polymer component will undergo a different extent of longitudinal shrinkage upon application of heat. The outer surface of the fiber may carry a water-repellant coating. The invention also provides a method of forming a drawn and/or crimped fiber exhibiting storage-stable tenacity.
    • 本发明提供一种包含生物可降解聚合物如聚乳酸的拉伸和/或卷曲纤维,其中拉伸和/或卷曲的纤维表现出储存稳定的韧性,其在制造时不会从初始强度降低超过约10% 在环境条件下储存120天后。 用于形成纤维的聚合物组合物可以包含软化剂。 纤维可以是螺旋自卷曲的拉伸和卷曲双组分纤维,其包含第一可生物降解的聚合物组分和第二可生物降解的聚合物组分,其中第一聚合物组分和第二聚合物组分显示不同的聚合物形态,使得每个聚合物组分 在施加热量时将经历不同程度的纵向收缩。 纤维的外表面可以携带防水涂层。 本发明还提供了形成具有储存稳定韧性的拉伸和/或卷曲纤维的方法。
