摘　　要：研究布基、洗涤浓度、浴比、水质、水温等洗涤条件对织物洗涤剂柔软性能的影响及测试方法条件下对产品的分档效果。结果表明,应选择针织棉白布为测试布基。柔顺剂柔软性能测试质量浓度为1 g/L,该条件下能对不同产品分档。洗衣液柔软性能测试条件为:(30±1)℃下在硬水配制的质量分数为2 g/L的洗涤溶液中放入5块布片,洗涤4轮。该测试条件下结果稳定可靠,一定范围内不同产品区分度较好。当某些产品性能接近洗涤4轮无法区分时,可适当增加洗涤次数来区分其优劣。The influences of washing conditions such as cloth base,washing concentration,bath ratio,water quality and water temperature on the softness by the use of fabric detergents were studied,and the grading of products under the condition of the testing method was studied.The results showed that white knitted cotton cloth should be selected as the test base.The testing mass concentration of softener was 1 g/L.Under this condition,different products could be graded.The test conditions to evaluate the softness for the washing liquids were as follows:at(30±1)℃,5 pieces of cloth were put into the washing solution with the mass concentration of 2 g/L prepared by hard water and washed for 4 cycles.The results under the test conditions were stable and reliable.Different products could be well distinguished within a certain range.When the performance of some products was close to each other and it was impossible to distinguish them by four washing cycles,the washing cycles could be appropriately increased to distinguish them.
