Lyopen dyeing machines are essential for dyeing knit and woven fabrics, but existing models have drawbacks like a high liquor ratio (1:8 - 1:13), causing energy waste and environmental issues. To address these, our company developed a new model with a patented double - layer fabric chamber (design No. 15). This innovation lowers the liquor ratio to 1:5, enhances dyeing quality, boosts efficiency, and cuts energy consumption. With advantages such as large capacity, low liquor ratio, and pressure adaptability, it sets a new industry benchmark for Lyopen dyeing machines.
