Recently, news about the rising dyeing fees of dyeing and dyeing enterprises came out frequently. The rising price of dyes directly affects the production cost of dyeing enterprises. In this upsurge of rising dyeing fees, how to reduce costs and increase efficiency and avoid risks for dyeing enterprises is one of the most concerned issues in the industry.

On April 9, the 18th National Technical Exchange on New Materials, New Technologies, New Technologies and New Products in Printing and Dyeing Industry was held in Shanghai. At the meeting, relevant industry experts, technology research and development and product developers discussed the current industry situation.

Chen Zhihua, President of China Printing and Dyeing Industry Association, presided over the meeting.

Innovating Green to Break through the “Platform Period” of Industry

Li Lingshen, Vice President of China Textile Industry Federation, said in his speech that at present, the downward pressure of China’s textile industry is great. The industry should start from the system construction, accelerate the construction of high-end leadership, promote the traditional industry to jump to the middle and high-end, vigorously develop high-end manufacturing, continuously optimize the industrial layout, and take the development path of improving quality and efficiency. “In order to achieve a higher quality, more efficient and more sustainable development of the printing and dyeing industry, we must continue to grasp the innovative development direction of material application, technology research, process optimization and product development. Through technological change, we can achieve quality change, efficiency change and power change, providing new momentum, opening up new paths and creating new advantages for the development of China’s textile industry in the new era. “Li Lingshen suggested that printing and dyeing enterprises should strengthen innovation drive to realize the transformation of new and old kinetic energy and high-quality development of the industry. Second, we should deepen the industry development and broaden the application of new and efficient materials. Thirdly, we should carry out our duty and strengthen the innovation of new dyeing and finishing technologies for energy saving and emission reduction. Fourth, we should seize the opportunity of the times and promote the penetration and integration of intelligent manufacturing technology and industry. Fifth, we should seize the market highland, adapt to consumer demand and lead consumer demand through product innovation.

Cao Xuejun, deputy director of the Consumer Goods Department of the Ministry of Industry and Information Technology, said that at present, the momentum of world economic growth has weakened, the textile industry has entered a new stage of transformation and upgrading, and the quantity has changed to quality. “Since 2012, the growth rate of China’s printing and dyeing industry has slowed down, and the global market share has declined. Nowadays, problems such as rising costs and difficult employment are becoming increasingly prominent. The printing and dyeing industry can be said to have entered a platform period. “

Cao Xuejun said frankly that this has put forward higher requirements for innovative technology and management of printing and dyeing industry. It is not only necessary to reform innovative thinking and promote the construction of enterprise management system, but also necessary for printing and dyeing enterprises to integrate responsibility consciousness and green development concept into enterprise management, strengthen the management of energy resources, sewage treatment and chemicals, and use information technology to promote intelligent management. The mechanism of the survival of the fittest. In addition, it is noteworthy that Cao Xuejun revealed that the Consumer Goods Department will organize and publish the green technology and equipment guide for printing and dyeing industry, provide guidance for the cleaner transformation and upgrading of all regions and printing and dyeing enterprises, increase the promotion and application of innovative advanced printing and dyeing technology, and build intelligent printing and dyeing factory, green enterprise and green supply chain.

High-tech breakthrough industry fog

The conference focused on process optimization, production line upgrading, industrial chain integration product collaborative development, Tencel, nylon, regenerated polyester, multi-component fabric dyeing and finishing, high waterproof, flame retardant and temperature change, light change, wet change and other functional fabrics dyeing and finishing, alkali-resistant disperse dyes, high-efficiency desizing agent, chelating dispersant and other new high-efficiency dyeing and chemical additives in the printing and dyeing industry. Deeply discuss and communicate with others.

Zhang Lei, technical service manager of Lanjing Fiber (Shanghai) Co., Ltd. in China, introduced the development and dyeing and finishing technology of Tencel-Lesser fiber textiles. He said that this kind of fiber has the properties of hygroscopicity, air permeability, comfort, good dyeability and environmental protection. It can be pure spinning, and can also be made by different textile and knitting processes with cotton, wool, silk, linen, chemical fibers and cashmere fibers. Blended fabrics with different styles can be used in home textiles, clothing and other fields.

In recent years, Hengtian Lixin has made some breakthroughs in dyeing and finishing technology and technology of new fiber knitted fabrics and has made some achievements. Liang Xilong, manager of Technological Application Center of Lixin Dyeing and Finishing (Shenzhen) Co., Ltd., shared the application of new dyeing machines in the field of multi-functional fibers and energy saving and emission reduction.

How to break through the encirclement of printing and dyeing enterprises under the heavy pressure of environmental protection? Zhang Ning, technical director of Jiangsu Xinruibei Science and Technology Co., Ltd., believes that the trend that enterprises need to follow is process continuity, process simplification, process ecology, spinning environmental protection, terminal product diversification and equipment iteration. It is understood that in recent years, the company’s efforts to develop “enzymatic auxiliaries” for textile, sewage and many other industries have been recognized by the National Textile Industry Association, more in line with ecological standards than traditional dyeing methods.

Shang Songmin, an associate professor in the Department of Textiles and Clothing, Hong Kong Polytechnic University, introduced bionic fabrics. He said the fabrics were inspired by Saharan desert ants, which use their unique wool coats to control electromagnetic waves over a wide spectrum to achieve the biological function of lowering body temperature. After research and development, the fabric has the characteristics of mid-infrared penetration and near-infrared reflection, which makes people feel comfortable and cool.

Xu Changhai, a professor of Jiangnan University, described in detail the dyeing process and properties of alkali-resistant disperse dyes. He pointed out that high alkali-resistant disperse dyes are not only suitable for dyeing polyester in weak acid conditions, but also suitable for dyeing polyester in neutral and alkaline conditions. The process of process execution is to combine the pretreatment and dyeing of polyester. After testing, the color fastness, color light and other indicators meet the requirements, which is a new process worthy of praise.
