One step pretreatment for printing and dyeing has been developed since the founding of the PRC. With the development of efficient auxiliaries and efficient equipment, it has been developing rapidly in recent years.

Wet cloth mercerization is difficult to control because of the moisture content of the fabric. The problems such as the penetration of strong caustic core and the automatic control of alkali concentration can not be overcome.

When dry cloth is mercerized, its former road must be dried after drying and drifting. The waste of steam is serious. In the current situation of energy shortage and energy price rising, China has built a resource-saving society to the strategic level of implementing Scientific Outlook on Development and building a harmonious society in an all-round way.

Under the excellent situation of clean production in China, tapping latent energy and reducing energy consumption in printing and dyeing industry become the target of printing and dyeing workers.

For this purpose, with the cooperation of printing and dyeing customers, combined with the current highly efficient technology and high efficiency auxiliaries, we have developed high-speed and efficient one-step pre-treatment.

And put into normal production, and achieved good results of popularization and application, walking in front of the same industry.

Social and economic benefits are very significant.

High speed and high efficiency one-step pretreatment and wet cloth mercerizing machine equipment flow.

The fabric is steamed immediately after steaming, and the steam is preheated by direct injection of saturated steam to make it reach the steaming temperature quickly. It is a unique design to ensure the steaming condition of the steamer in the wet and fast heating.

In order to ensure high speed, high efficiency and high temperature washing and water saving, the joint washing machine has made great innovations in energy saving and emission reduction. The high efficiency steam washing unit adopts the design of the snake like water flow, the grid washing and the grid based countercurrent system, and the fabric washing fluid countercurrent exchange, the washing liquid concentration and the shaving difference is big, the fabric cleaning is easy, and the bottom water level design is adopted, with less water storage, fast heating, less steam consumption and less heating time.
