摘要
胀破强度是非织造布的重要性能之一。本文使用了四种试验半径,分别对木浆水刺、纺粘-熔喷-纺粘(SMS)和热熔三种非织造布进行了测试。通过滤除试验膜片的影响,并对修正后数据进行单峰拟合,获得了热熔和SMS非织造布胀破强度的准确数值。本文还研究了试验半径对测试数据的影响,应用弹性力学理论和实验数据,给出了两者的半经验公式:q0=k/r3。
The burst strength is one of the most important characteristics for nonwovens.The strength of three kinds of the nonwoven were detected under four testing radius,including the wood spunlace nonwoven,the SpunbondMeltblown-Spunbond（SMS）nonwoven and the melt nonwoven.The precise results of the SMS and the melt nonwoven could be received by removing the influence of the elastic membrane and the single-peak fitting.The influence of the testing radius to the strength results was also studied,and the semiempirical formula（q0=k/r^3）was deduced using the elastic mechanics theory and testing data.
