摘要: 单向弹性绸是一种能随气流冲击载荷作用的变化产生变形来调节透气量大小的降落伞绸织物,而透气性是降落伞绸的重要性能指标。依据“歼十”飞机救生系统中降落伞使用时对伞衣织物透气性能的要求,本次实验共设计织造了15种不同织物结构参数(如外包捻度、预牵伸倍数等)的单向弹性绸织物。通过对织物结构参数与透气量关系的分析,找到了影响单向弹性绸织物透气量的主要因素。得出单向弹性绸织物的透气量随经密的增大而减小;随外包捻度的增大先增大后减小,在1000T/10cm时单向弹性绸织物透气量达到最大值的结论。

Abstract: Weft elastic silk fabric is a kind of parachute fabric. Due to the diversification of air impact load, the size of the fabric changed. As a result, the volume of air permeability changed. In the parameters of the properties of the parachute silk, the air permeability is an important parameter. According to the requirements of the air permeability performance of the parachute fabric, 15 types of weft elastic parachute silk, different outsourcing twist and different pre drafting ratio, have been designed. The relationships between the structure parameters of the fabrics have been researched, and the major factors impacting the air permeability of weft elastic silk fabric was found. It was found that the great warp density favors the small air permeability of the fabric. In addition, the air permeability of the fabric increased and decreased with the increase of the outsourcing twist. The air permeability of weft elastic parachute silk is the biggest when the outsourcing twist is 1000T/10cm.
