To Become A Strong Nation In Dyeing And Printing Industry, We Must Have An Innovative Gene.

With the state

And the elimination of backward production capacity, dye and pigment industry has been pushed to an important juncture.

At the sixteenth China International dyestuff industry and organic pigment and Textile Chemicals Exhibition, the relevant directors and exhibitors of the China Dyestuff Industry Association agreed that if China wants to become a strong power of dyestuff production, it must activate every innovation gene in the industry cell, accelerate the integration and automation pformation of the industry, accelerate the innovation and development of product's ecological safety and functionality, focus on developing products that meet the market demand and have high added value, improve the competitiveness of the industry in the world, and make China made for the creation of China.

"At present, the production of dyestuff and pigment in China has been improved by technological pformation, but most of them are still operated in extensive, open, intermittent and labor-intensive ways, which have poor ability to deal with emergencies in environmental protection and safety incidents, and the reaction control is not precise enough, which is likely to cause instability in product quality, difficult to meet the requirements of yield, and high production cost.

Lack of competitiveness.

In this regard, the existing production mode should be reformed. "

Zhang Yanshen, senior engineer of China Dyestuff Industry Association, said.

The development plan for the dyestuff industry in 13th Five-Year is also clear.

"Planning" pointed out that the future industry needs to strengthen the reaction equipment closed, integrated, intelligent and information pformation, in order to achieve the whole process of reaction temperature, acidity, pressure, flow rate, reaction rate and other process parameters automation, improve the atomic utilization of raw materials, reduce excess substances, make the reaction more accurate and reasonable.

At the same time, a number of automatic production lines, such as dyestuff, pigment and intermediates, should be built. Through upgrading and demonstration, the overall technology and equipment level of the industry will be upgraded.

For existing

Art is still relatively backward, and the design of routes and methods for key intermediates synthesis reactions is not reasonable. The plan pointed out that the key production technologies should be improved, optimized, systematized and integrated, and improved in terms of safety and operational stability.

Especially in the process of technological pformation, we should pay attention to the optimal combination of materials and energy in the whole process of production, so as to improve the comprehensive utilization of resources.

They are high solubility, high intensity reactive dyes, acid dyes and organic pigments for 20%~30%. They are disperse dyes, reactive dyes, acid dyes and organic pigments that are suitable for dyeing and finishing technology of superfine fiber, Gao Fangmian fiber, multi-functional composite fiber and wool. Transfer printing technology, pigment printing and dyeing technology, microcapsule dyes, no auxiliaries and no wash dyeing technologies are needed for new energy saving and emission reduction green dyeing and printing technologies. Pigments and pigments that meet the needs of high-end products such as special engineering plastics and so on are suitable for high light flux, high color saturation value and high engineering pigments in pportation, life sciences, electronic chemicals and new energy chemicals, so as to meet the requirements of lightweight, high strength, high temperature resistance, shock absorption and so on. The plan also pointed out that in the future, the development and innovation of high-end products should be strengthened. The research emphasis should be on the solubility of high intensity needed for inkjet printing.
