    • This invention is a bicomponent meltblown microfiber nonwoven material wherein at least two different polymers have been extruded and spun together in either a side by side or core/sheath configuration and wherein at least one of the polymers is polytrimethylene terephthalate (PTT) and at least one of the polymers is one of but not limited to the following thermoplastics: polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyamide (PA), and polylactide (PLA). The ratio of PTT to the other component ranges from 1:99 to 99:1, based on the weight of the polymers. The preferred weight ratio range of PTT:PP is 25:75 to 75:25 and the most preferred range is 25:75 to 50:50. The present invention also provides a process for making such a bicomponent fiber. The present invention also provides a process for making such a meltblown microfiber nonwoven material.
    • 本发明是一种双组分熔喷超细纤维非织造材料,其中至少两种不同的聚合物已被挤出并以并列或芯/鞘构型纺丝在一起,并且其中至少一种聚合物是聚对苯二甲酸丙二醇酯(PTT)和至少一种 的聚合物是聚丙烯(PP),聚乙烯(PE),聚对苯二甲酸乙二醇酯(PET),聚对苯二甲酸丁二醇酯(PBT),聚酰胺(PA)和聚丙交酯(PLA)等热塑性塑料之一。 基于聚合物的重量,PTT与其它组分的比例为1:99至99:1。 PTT:PP的优选重量比范围为25:75〜75:25,最优选的范围为25:75〜50:50。 本发明还提供了制备这种双组分纤维的方法。 本发明还提供了制造这种熔喷超细纤维非织造材料的方法。
