本标准规定了纺织染整助剂中防水防油加工剂防水性的测试方法。
将防水防油加工剂按照一定的工艺条件整理到织物上，在规定的条件下，水流喷淋到绷紧的织物试样表面，形成一个润湿的图案，润湿图案的大小与织物的防水性能有关，参照评级图卡进行评级，确定防水性能的等级，等级越高，防水性能越好。
以含固量为20％的防水防油加工剂为基准，用水配制成15g/L的工作液，需要时用冰醋酸调节pH值至5.0～7.0。
将250mL(27±1)℃的水喷淋到测试仪的漏斗中，控制在25 s～30 s内喷淋到试样上。
敲击完以后，立即将试样上润湿图案与评级标准图卡(附录B)对照，根据最接近的标准图，评定试样的防水等级。
This standard specifies the test method for water repellency of water and oil repellency agents in textile dyeing and finishing auxiliaries.
The water and oil repellency agent is applied to the fabric under certain process conditions; under specified conditions, water is sprayed onto the taut fabric specimen surface, forming a wetting pattern; the size of the wetting pattern is related to the water repellency of the fabric; rating is performed by referring to the rating chart to determine the water repellency grade; the higher the grade, the better the water repellency.
Based on a water and oil repellency agent with a solid content of 20%, prepare a working solution of 15 g/L with water, and adjust the pH to 5.0～7.0 with glacial acetic acid if necessary.
Spray 250 mL of water at (27±1)℃ into the funnel of the tester, controlling the spray onto the specimen within 25 s to 30 s.
Immediately after tapping, compare the wetting pattern on the specimen with the standard rating chart (Annex B) and assess the water repellency grade of the specimen based on the closest standard chart.
