Shishi Printing And Dyeing Process To Achieve Anhydrous

Recently, the reporter learned from the industry that Shishi has developed a double-sided cold dyeing and dyeing machine. Under the same capacity, it saves 640 thousand tons a year and saves 3500 tons of steam. So far, the research and development has entered the market promotion period.

Dyeing and finishing industry is

Industries with high energy consumption and high resource consumption.

Wu Guangyu, Secretary General of Shishi dyeing and finishing industry association, told reporters that in the aspect of dyeing, the ratio of bath in the past few years (the ratio of dyed fabric to dye solution) reached 1: 10 or even 1: 12, that is to say, 1 tons of cloth can be used for 10 ton to 12 tons of water. With the continuous improvement of textile machinery technology, the dyeing bath ratio has dropped to 1: 8, or 1: 6, but overall it is still a high water consumption industry.

Controlling dyeing bath ratio in dyeing process and implementing less water process is also the focus of dyeing and printing equipment manufacturers.

The traditional process has only 30% to 40% utilization of pigment, and more than half of the pigments are washed away by clear water, which not only pollutes water but also pollutes the environment.

Zhu Hongbo, assistant director of the Japanese crown (Fujian) Textile Machinery Co., Ltd., said that the newly developed double-sided cold dyeing and dyeing machine has changed the traditional bath, flat screen, round screen dyeing, high temperature fixation and other dyeing and printing methods. Through special pretreatment agents, four printing rolls will directly print the colors and patterns onto the white cloth.

According to the introduction, the pure natural plant dye developed independently does not cause pigment diffusion on the cloth surface in the process of using the watermark. At the same time, it can infiltrate the pigment into the plant fiber, which has high color fastness and can achieve double sided printing and dyeing.

Because the printing and dyeing process does not require water in the whole process, it can save 640 thousand tons of water a year under the same capacity.

After dyeing and printing, it can be fixed at room temperature, and the utilization rate of pigment can be increased to 97%. Under the same capacity, 3500 tons of steam can be saved.

By using gravure printing and printing, the design pattern can show the special dyeing effect of traditional batik, tie dye, lifting and dyeing and denim clothing, and so on.

Zhu Hongbo introduced that the machine introduced the numerical control technology, the use of computer technology, so that the accuracy of each line in the pattern can reach 0.1 millimeters, and can be dyed 50 meters per minute.

Insiders said that 2008 is the watershed of the dyeing and finishing industry. Before that, many enterprises followed the trend of imitators. Later, more people realized that independent research and development had a way out.

Wu Guangyu said that the automation and intellectualization degree of dyeing and printing equipment has been increasing, the machine stability is better, the operation is more simple and the working efficiency has been improved.

Originally, a printing and dyeing production line needs more than 20 workers, and only 3 workers are needed after the introduction of intelligent use.
