无味载体DM-2308对涤纶低温染色性能研究

Odorless Carrier DM-2308 Based Low Temperature Dyeing Properties of PET Fabrics

文中介绍了环保无味载体DM-2308的基本性能,并用于涤纶织物低温染色。探讨了不同温度、时间、p H值和载体用量对染色织物K/S值的影响,比较了低温载体法和高温高压法的染色效果,测试分析了K/S值、染色牢度,并将DM-230应用于生产实践中。结果表明,载体用量为3%,p H值为4.5~6.5,温度110℃、时间60 min,K/S值可以达到130℃高温高压常规染色工艺的91%以上,耐皂洗色牢度、耐摩擦色牢度与常规染色工艺基本一致;低温载体DM-2308染色法在涤毛织物大生产低温染色中K/S值大于26,可大幅提升分散染料低温染色的上染率,能够满足涤纶混纺织物低温染色的要求。

In this paper, the basic performance of environmentally friendly odorless carrier DM-2308 was intro- duced and used for low temperature dyeing of polyester fabric. The effects of different temperatures, time, pH val- ued and the dosages of Carrier DM-2308 on the coloration of dyed fabrics were discussed. The effects of low tem- perature carrier method and high temperature and pressure method were compared. The K/S value and color fast- ness were tested and analyzed. The application of DM-230 in practical production was introduced., and the appli- cation of DM-230 in practical production was introduced.The results show that when the dosage of the carrier is 3%, the pH value is 4.5-6.5, the time is 60 minutes at 110℃, and the K/S value could reach more than 91% of the conventional high temperature and high pressure dyeing process;The use of carrier DM-2308 in the production of low-temperature dyeing of polyester/wool fabric,the K/S value more than 26, can greatly improve the dye-uptake of disperse dyes, which can meet the requirements of low temperature dyeing of polyester blended fabric.
