摘要
非织造布拉伸试验中试验条件对测试结果有很大的影响。对试样宽度、长度、长宽比和拉伸速率等因素进行了拉伸正交试验。结果表明:试样宽度对拉伸断裂强力的影响最大,达到显著影响的程度;其次为拉伸速率,拉伸速率太小使断裂强力偏低;长宽比和长度的影响不大。
Test conditions execute a great effect on the tensile properties of nonwovens. The effects of specimen width,specimen length and tensile rate on the yield were studied via tensile orthogonal experiments in this paper. The result indicates that specimen width has the most important influence of tensile breaking strength , and reaches a significant degree. Secondly, breaking strength decreases significantly when tensile rate is at a low level. There is little influence of specimen length and length-width ratio.
