名称及摘要

包括聚羟基链烷酸酯共聚物/聚乳酸聚合物或共聚混合物的纤维
本发明公开了在环境中可降解的熔纺纤维,该纤维包括聚羟基链烷酸酯共聚物和聚乳酸聚合物或共聚物。本发明的优选构型涉及在环境中可降解的纤维,该纤维包括皮/芯式结构,其中芯包括可生物降解的聚羟基链烷酸酯共聚物,皮包括聚乳酸的聚合物或共聚物。本发明也公开了包括在环境中可降解的纤维的无纺纤维网和一次性制品。
Fibers comprising polyhydroxyalkanoate copolymer/polylactic acid polymer or copolymer blends
Environmentally degradable melt spun fibers comprising a polyhydroxyalkanoate copolymer and a polylactic acid polymer or copolymer are disclosed. A preferred configuration of the present invention is directed to environmentally degradable fibers comprising a sheath/core structure where the core comprises a biodegradable polyhydroxyalkanoate copolymer and the sheath comprises a polymer or copolymer of polylactic acid. Nonwoven webs and disposable articles comprising the environmentally degradable fibers are also disclosed.
