摘要
分别参照标准ISO9703-3与标准JISL1096-2010测试了丙纶非织造布的拉伸力学性能,通过试验发现:两个标准测试条件主要是拉伸速度不同,在两个标准下测得的拉伸强力与拉伸断裂伸长率的值相差不明显,拉伸强力与拉伸断裂伸长率的变异系数相差较大。
According to ISO 9703-3 and JIS L1096-2010, the tensile mechanical properties of polypropylene nonwovens were tested. It was found that the main test conditions of the two standards were different tensile speed, the difference between the tensile strength and elongation at break was not obvious, and the coefficient of variation of tensile strength and elongation at break was quite different.
