热熔粘扣带抗疲劳性能与黏结点的关系

Relationship between anti-fatigue performance of Velcro and bonding points

研究热熔粘扣带抗疲劳性能与黏结点的关系。普通钩面带在地组织经纬纱中并入热熔丝,热熔丝熔融后在经纬纱交织处形成一定数量的黏结点。通过对粘扣带进行0~5 000次的抗疲劳试验,对抗疲劳性能衰减指数f与黏结点个数m进行拟合得到非线性回归方程。结果显示,随着黏结点个数的增加,粘扣带的抗疲劳性能先降低后提高。该回归方程可以预测粘扣带在不同黏结点个数下的抗疲劳衰减指数,对研究粘扣带的抗疲劳性能具有重要指导意义。

The relationship between anti-fatigue performance of Velcro,filled with hot-melt yarns,and bonding points was studied. Adding hot-melt yarns in warp or weft,bonding points could be formed in the position of interlace points. The fitting equation between anti-fatigue performance attenuation index and bonding points was obtained by the means of the nonlinear regression analysis of 0 - 5 000 times test. It was shown that with the increase of bonding point numbers,anti-fatigue performance declined first and then improved. The fitting equation could be used for forecasting the anti-fatigue performance attenuation index, which was important for studying the anti-fatigue performance of Velcro.
