除油剂TF-115D除油染色一浴工艺的生产应用

Application of Degreaser Tf-115D in One-Bath Process of Degreasing and Dyeing

化纤织物织造过程中需要用到大量油剂,在染整加工时会影响染色性能,如色疵、色花、染色不匀等问题,因此,化纤织物的前处理除油尤为重要。文中首先筛选除油剂,并将其应用到涤氨、锦氨针织物的前处理除油,并进行平幅水洗除油和除油染色一浴工艺实践。结果表明,除油剂TF-115D具有较好的去油效果,可用于化纤织物的前处理除油;对于锦氨和涤氨油污针织物,当除油剂TF-115D为2.0 g/L,纯碱1.5 g/L,80℃处理20 min时,可以获得较好的除油效果,平幅水洗除油生产实践效果较好。除油染色一浴工艺中,除油剂TF-115D用量为2.0 g/L时,具有理想的除油效果,对染色织物的得色量和色光影响极小,实现均匀染色的同时可以有效节省时间,节约用水、用电和蒸汽能源,降低加工成本。

A large amount of textile oil is needed in the knitting process of chemical fiber fabrics, which may influence the dyeing performance during dyeing and finishing, such as color enamel, uneven dyeing, etc, therefore the pretreatment of chemical fiber fabrics is particularly important. This paper firstly screened the degreaser and applied it to the pretreatment and degreasing of polyester ammonia and nylon knitted fabrics, and then performed it in one-bath process production of flat-width water washing and degreasing. The results show that the degreaser TF-115D has good degreasing effect and can be used for pretreatment and degreasing of chemical fiber fabrics. For the nylon and polyester ammonia knitted fabrics, when the dosage of degreaser TF-115D is 2.0 g/L, soda 1.5 g/L, at temperature 80 ℃ for 20 minutes, good degreasing effect can be obtained, and the effect of the practice of flatwidth water washing and degreasing is better. In the one-bath process of degreasing and dyeing, when the amount of degreaser TF-115D is 2.0 g/L, the ideal degreasing effect can be obtained, which has little effect on the color yield and shade of dyed fabrics, and uniform dyeing can achieved with saving of time, water, electricity, steam energy and thus the processing cost.
