摘要

研究了连续针刺织机附加冲孔操作的持续时间对织物常规应力和相对拉伸伸长率的影响。操作持续时间对常规断裂应力有很大影响,而对相对断裂伸长率几乎没有影响。在织物第一次通过针刺织机时,织机连续运行 2 天后,织物纵向和垂直方向的常规应力降低了 10-15%,8 天后则完全降低了 20-30%。常规断裂应力与织物的密度相关。我们提出了一个方程式,用于预测附加冲孔过程中织物常规应力变化与织物体积密度之间的比率,该比率是织机连续运行时间的函数。

Influence of Needlepunch Loom Operation Time on Physicomechanical Properties of Nonwoven Fabric

Influence of Needlepunch Loom Operation Time on Physicomechanical Properties of Nonwoven Fabric

The influence of duration of continuous needlepunch loom operation for additional punching on conventional stress and relative tensile elongation of fabrics was studied. Duration of operation considerably affects the conventional breaking stress and has practically no effect on relative breaking elongation. During the first fabric passage through the needlepunch loom, the conventional stress in the longitudinal and vertical directions of the fabric in 2 days of continuous operation of the loom diminishes by 10−15 % and totally in 8 days, by 20−30 %. Conventional breaking stress correlates with /bulk density of the fabric. An equation is proposed for predicting the ratio between the change of the conventional stress and the bulk density of the fabric in the process of additional punching as a function of duration of continuous operation of the loom.
