Problems solved by technology

[0002] At present, the most research and development of energy-saving dyeing technology is the cold pad-batch dyeing technology. In the actual development and application, the cold pad-batch technology developed for woven fabrics has been applied correspondingly, but there are the following problems in the low-temperature dyeing process of knitted fabrics: 1. 1. Knitted fabrics are prone to quality problems such as folds in the cold pad batch; 2. Since the cold pad batch technology needs to stack the cold rolled fabrics for 12 to 24 hours, it takes up time and requires a large area for stacking , low production efficiency
