Tensile Behavior of the Knots for Spun Yarns of Different Flax Types

ABSTRACT

In this paper, the spun yarn specimens of two types of flax fibers, i.e. flax tow fiber and hackled line flax, were used for statistical study on main trends of tensile behavior of knotted spun yarns. The tensile characteristics, such as breaking force, tenacity, elongation at break, work of break, and specific work of break of knotted yarns, were compared with those of original yarns. The above-mentioned indices were studied for four types of textile knots, i.e. the square, the overhand, the weaver’s, and the fisherman’s knots. Several aspects of tensile behavior as stress concentration, hastened breakage, knot slippage, and others were applied in the discussion.

摘要

在本文中，分别使用两种亚麻纤维（即纤维丝束和梳理线亚麻）的细纱标本对打结纱的拉伸性能的主要趋势进行统计研究。打结纱的拉伸特性（如破断力、韧性、断裂伸长率、断裂工作情况）等与原纱进行了对比。通过上述指标，本文对四类纺织品结（即方型结、反手结、织结和渔网结）进行了研究。研究中讨论了拉伸行为的几个方面（例如应力集中、加速破损、滑脱结和其他方面）的应用。
