摘要：
A multi-component fiber that includes a core component surrounded by a distinct sheath component is provided. The core component is formed primarily from polylactic acid and the sheath component is formed primarily from a polymeric toughening additive. The sheath/core configuration may provide a variety of different benefits to the resulting fiber. For instance, the polymeric toughening additive can help increase the ability of the fiber to absorb energy that arises from stresses imparted during fiber drawing, which increases the overall toughness and strength of the fibers. At the same time, the presence of the toughening additive in the sheath component can enhance the degree of bonding to other fibers (the same or different), such as when employed in a nonwoven web material. Another benefit of the present invention is that the sheath/core configuration may be formed from a thermoplastic composition in which the polylactic acid and polymeric toughening additive are blended together.
摘要（中）：
提供了一种多组分纤维，其包括由不同的鞘组分包围的核心部件。 核心组分主要由聚乳酸形成，并且鞘组分主要由聚合物增韧添加剂形成。 护套/芯体配置可以为所得纤维提供各种不同的益处。 例如，聚合物增韧添加剂可以帮助增加纤维吸收由拉伸过程中施加的应力引起的能量的能力，这增加了纤维的整体韧性和强度。 同时，鞘组分中增韧添加剂的存在可以增强与其它纤维（相同或不同）粘合的程度，例如当用于非织造网材料时。 本发明的另一个好处是鞘/芯构型可以由其中将聚乳酸和聚合物增韧添加剂混合在一起的热塑性组合物形成。
