Wuxi Jinhao Printing and Dyeing Machinery Co., Ltd. recently designed and developed the JH-600 series of high-temperature, high-pressure, low-bath ratio jet dyeing machine. This series of products avoids the problem that the O-type dyeing tank is less applicable and the L-type dyeing tank uses more water. The combination of advantages (low bath ratio, wide range of fabrics suitable for printing and dyeing) can promote the green sustainable development of printing and dyeing enterprises.
