Soft Polyester Fiber Dye Selection and Dyeing Considerations
(Zhejiang Kaichuang Industry and Trade Co., Ltd.)
Ultra-soft polyester fiber (Pastel) is a new type of super-natural modified fiber. It is not only soft, but also has excellent anti-pilling properties. It combines the softness and skin-friendly properties of natural fibers. The performance also retains the characteristics of polyester fiber, and it is easy to dye at room temperature, energy saving and environmental protection.
1. Selection of dyes Ultra-soft polyester fiber dyeing can be SD type cationic dye, E type disperse dye, X-type cationic dye, which is most suitable for dyeing cationic X-type dyes. It has the characteristics of complete chromatogram, bright color and high color fastness.
2. Precautions for dyeing Polyester fiber (Pastel) is dyed with X-type cationic dye, and the interval of dyeing curve is very narrow, ranging from 90 °C to 100 °C, and a large amount of concentrated dyeing in a short time. In the dyeing process, X-BL Lan is the first to be dyed, and x-GRL red is dyed in the later stage. Compared with the whole-gloss, the color is not synchronized, which is easy to cause color flower. The dyeing process should pay attention to the heating rate and the amount of additives. .
Ju cool fiber (Pastel) dyed dark, especially black, the dyeing rate is slightly poor, not dyed deep, to add depthening agent and extend the holding time to reach the dyeing depth.
With the continuous development of the application of ultra-soft polyester fiber (Pastel), the market is increasingly demanding from the market, and the prospects are very promising. There are still some unsatisfactory places in the dyeing, and further exploration is needed.
The led solar tube is charged during the day and automatically lights up at night because there is a voltage detection circuit inside the lamp, which detects that the voltage of the solar panel is higher during the day, and the detection circuit outputs a control signal to turn off the sun tube light. At night, the voltage of the solar panel is almost Zero, the detection circuit outputs a control signal to light the solar tube light.
