This standard specifies the test method for oil repellency of water and oil repellency agents used in textile dyeing and finishing auxiliaries, applicable for evaluating their oil repellency performance. The principle involves applying the agent to fabric and using a series of hydrocarbon standard test liquids with different surface tensions to assess wetting; the oil repellency grade is the highest number of test liquid that does not wet the fabric. The standard details steps for working solution preparation, fabric preparation, drop application, and rating rules, referencing GB/T 6529, GB/T 6682, and GB/T 8170. Annexes provide composition of standard test liquids, wetting judgment diagrams, and a method for determining solid content.
本标准规定了纺织染整助剂中防水防油加工剂防油性的测试方法，适用于该类助剂的防油性能评估。测试原理是将助剂整理到织物上，用一系列不同表面张力的碳氢化合物标准测试液评价织物的润湿情况，以不润湿的最高测试液编号作为防油等级。标准详细描述了工作液配制、织物制备、滴液操作、评级规则等步骤，并引用了GB/T 6529、GB/T 6682和GB/T 8170等文件。附录提供了标准测试液组成、润湿判定示意图和含固量测定方法。

本标准规定了纺织染整助剂中防水防油加工剂防油性的测试方法。
防油等级以织物表面不润湿的测试液的最高编号表示，等级越高，防油性能越好。
从最低级数的测试液开始，沿着测试织物纬向在5个不同位置滴加液滴（直径5 mm或0.05 mL），两滴液滴之间需至少分开4.0 cm。
当测试液滴中5滴中有3滴或更多表现出有渗透或润湿以及接触角下降的现象时，说明试验失败。
拒油测试需在两块试样上分别测试，如果这两块测试样结果相同则报告该结果，如果结果不同，则需要进行第三次测试。
This standard specifies the test method for oil repellency of water and oil repellency agents in textile dyeing and finishing auxiliaries.
The oil repellency grade is expressed by the highest number of the test liquid that does not wet the fabric surface; the higher the grade, the better the oil repellency.
Starting from the lowest grade test liquid, drop liquid drops (diameter 5 mm or 0.05 mL) at 5 different positions along the weft direction of the test fabric, with at least 4.0 cm between two drops.
When 3 or more out of 5 test liquid drops show penetration or wetting and a decrease in contact angle, the test is considered failed.
The oil repellency test shall be performed on two specimens separately; if the results are the same, report that result; if different, a third test is required.
