摘　　要：在对胀破强度测试标准GB/T 7742.1—2005《纺织品织物胀破性能第1部分胀破强力和胀破扩张度的测定液压法》的试验条件进行研究时发现:试验面积与胀破强度有一定的反比例关系,对于同一试样,旧标准推荐试验面积7.3 cm2下的胀破强度约为现行标准推荐试验面积50 cm2下胀破强度的3倍;胀破速度对胀破强度影响较小,胀破速度提高时胀破强度会略微增加;胀破速度和胀破时间在小范围内调整时具有一定的线性关系,按比例调整胀破速度可以快速获得标准规定的胀破时间;该测试方法具有较好的精密度,均匀试样测试结果的变异系数CV值小于1%。Bursting strength is an important index of textiles mechanical properties.Some relations of the test parameters were found on the study of GB/T 7742.1—2005.Test area and bursting strength have an inverse relation.For the same sample,the breaking strength of old standard recommended area 7.3 cm2 is about 3 times of that of the existing standards recommended area 50 cm2.Bursting speed has little effect on the bursting strength.Bursting strength would increase slightly when bursting speed increase.There is a certain linear relationship between bursting speed and bursting time in small adjustments arrangement.So bursting speed could be adjusted quickly to the standard bursting time.This test method has good precision,and the coefficient of variation（CV） of uniform sample test results is less than 1%.
