AI Technical Summary
When using waste heat and solar energy for dyeing, the problem of inconsistent temperature leads to poor dyeing results, especially in the process of dyeing with reactive dyes where it is difficult to maintain constant temperature.
The two-dip multi-roll method is adopted, which combines multiple dips and rolls with stacking. Using a dyeing solution of reactive dyes, sodium carbonate and sodium sulfate, the dye is forced to penetrate and diffuse into the fiber. It can adapt to temperature changes of 60-90℃ and can be used for both constant temperature and variable temperature dyeing.
It achieves stable dyeing results over a wide temperature range, reduces energy consumption, provides new application avenues for waste heat and solar energy, improves dyeing performance and color fastness, and is suitable for dyeing with dual reactive dyes.
