The flat width dyeing and finishing process has the unique advantages of high degree of automation of equipment, complete automatic detection and control means and methods of various technological parameters, continuous production, high production efficiency, low labour cost and stable product quality. It is the preferred printing and dyeing processing means for cellulose fibres and blended and interwoven woven fabrics. However, if the quality, process, technology and operation management are not in place, it is often easy to have batch quality problems, leading to batch rework, increasing quality costs, or in heavy cases, causing inferior products that cannot be reworked and cannot be delivered, seriously affecting the company’s production schedule, economic efficiency and reputation.
