本标准规定了涤用匀染剂高温分散性的试验方法。
通过在分散染料染色工作液中加入涤用匀染剂,升温到130℃处理一定时间,然后降温到90℃,用真空泵抽滤,根据滤纸上残留染料的凝聚情况来评价高温分散性,评级结果最高为5级,最低为1级。
涤用匀染剂按附录A规定的方法测定其含固量,然后换算为20%的含固量进行以下试验。
将两层中速定性滤纸叠放入布氏漏斗,用90℃的热水润湿并预热滤纸和布氏漏斗,打开真空泵,调节控制阀使真空度为(0.02±0.005)MPa,将85℃~90℃的工作液倒进漏斗中过滤。
对比加入涤用匀染剂前后的高温分散性,加入涤用匀染剂后级数提升越多,表明涤用匀染剂的高温分散性越好。
This standard specifies the test method for the high temperature dispersibility of levelling agents for polyester.
By adding the levelling agent for polyester into the disperse dye dyeing liquor, heating to 130°C for a certain time, then cooling to 90°C, filtering with a vacuum pump, the high temperature dispersibility is evaluated based on the agglomeration of residual dye on the filter paper, with the highest rating being grade 5 and the lowest grade 1.
The solid content of the levelling agent for polyester shall be determined according to the method specified in Annex A, and then converted to 20% solid content for the following test.
Place two layers of medium-speed qualitative filter paper into the Buchner funnel, wet and preheat the filter paper and funnel with 90°C hot water, turn on the vacuum pump, adjust the control valve to a vacuum of (0.02±0.005) MPa, and pour the working liquid at 85°C to 90°C into the funnel for filtration.
Comparing the high temperature dispersibility before and after adding the levelling agent for polyester, the greater the grade improvement after adding the levelling agent, the better the high temperature dispersibility of the levelling agent for polyester.
