氟系防水整理的影响因素

Factors exerting influence on fluorine-based water repellent finishing

影响氟系防水剂防水效果的因素包括试织物、防水剂类型、pH值、防水剂用量、焙烘温度和时间及加工持续性等,而织物表面的Zeta电位是影响氟系防水剂乳液加工持续性的重要因素,在新产品开发过程中,应注意控制该指标。防水整理时,需根据织物类型选择防水剂和加工工艺条件。

The influencing factors on waterproof effects of fluoride waterproof agents are introduced, including types of finishing fabric and waterproof agents, pH value, finishing agent dosage, curing temperature and time, as well as processing reproduc- ibility. It is pointed out that Zeta potential is a main factor affecting the processing reproducibility of fluoride waterproof agent e- mulsion, which needs to be paid more attention in new product development. The type of waterproof agent and finishing process depend on the type of finishing fabric.
