Energy conservation and emission reduction: Updating equipment in the dyeing and finishing industry

The dyeing and printing industry is a key industry, but it is also an energy-consuming and polluting industry. Faced with a severe energy-saving and emission-reduction situation, dyeing and printing enterprises are under unprecedented pressure. However, in the face of this pressure, some enterprises have not remained stagnant but have instead risen to the challenge. Recently, reporters learned from relevant sources that many dyeing and printing enterprises have invested heavily in technological transformation of their equipment to reduce energy consumption and pollution while maintaining a certain production capacity.

Airflow tanks are popular in the dyeing and printing industry.

Several years ago, energy saving and emission reduction were regarded as an important task. The dyeing and printing industry was the first to be affected, with multiple increases in wastewater discharge standards and wastewater treatment fees. To reduce production costs and expand production capacity, some dyeing and printing enterprises have started energy-saving and emission-reduction efforts from equipment, production processes, and wastewater post-treatment processes. As a result, advanced foreign airflow tanks have first entered the procurement list of dyeing and printing enterprises.

It is understood that compared to traditional J-type tanks, airflow tanks have characteristics such as smaller bath ratio, lower energy consumption, and less waste discharge, and are hailed as environmentally friendly green equipment of the 21st century. In 2007, a buying frenzy for airflow tanks swept through the dyeing and printing industry. That year, 54 airflow tanks were installed and used in the county, with 10 of them being put into operation after installation and debugging by the end of the year.

To this day, the enthusiasm of dyeing and printing enterprises for purchasing airflow tanks remains unabated. According to relevant regulations, by the end of September this year, Zhejiang Yichuang Dyeing and Printing Co., Ltd. will shut down 23 J-type tanks, significantly reducing the constraints on the production capacity of the enterprise. In the first half of this year, "Yichuang Dyeing and Printing" spent a huge amount of money to introduce 11 airflow tanks from Germany, eliminating some backward production capacity, and currently, production orders are overwhelming.

Digital printing has been successively put into use.

Digital printing machines are another key production equipment that is being procured in the dyeing and printing industry. This type of equipment applies production processes similar to inkjet printers to the field of fabric dyeing and printing, achieving nearly zero pollution and zero emissions, which is favored by some dyeing and printing enterprises.

Enterprises benefit greatly from equipment updates.

The introduction of new equipment by various enterprises has not only reduced energy consumption but has also brought many visible benefits to the enterprises.
