Development and Mechanical Characterization of Needle-punched Kapok-Flax Nonwovens for Technical Uses

&
 

ABSTRACT

In this study, sandwich nonwoven fabrics containing raw kapok and flax fibers were developed and produced on a needle-punching processing line for agrotextile/geotextile applications. A two-step approach has been devised to produce nonwovens with compatible mechanical performance. Different structural arrangements were tried, and the mechanical properties of the resulting sandwich fabrics characterized. The nonwoven structures integrating 100% raw kapok fiber layers showed superior mechanical performance, compatible with class III geotextiles.

摘要

在本研究中,含原木棉和亚麻纤维的夹芯无纺布是在农业纺织/土工布的针刺加工线上开发和生产的.设计了一种两步法生产具有兼容机械性能的非织造布.尝试了不同的结构安排,并对所得夹层织物的力学性能进行了表征.结合100%原木棉纤维层的非织造结构表现出优越的力学性能,与三类土工布相容.
