Chinese civilization has been inherited for more than five thousand years, and accumulated rich ecological wisdom. The philosophical thought of "harmony between man and nature" and "Taoist nature" is the classical poetry of "persuading the emperor to fight three spring birds, and the son to return to his mother in the nest".
During the Shang and Zhou dynasties, there was a full-time official in the palace handicraft workshop, who had "dyed people" to "dye the grass", and managed dyeing production. In the Han Dynasty, dyeing technology reached a fairly high level. In ancient China, plants were used as dyes, and red in dyes could be extracted from madder, safflower, Su Fangmu and so on. Yellow was extracted from Gardenia, Jiang Huang and Sophora japonica, and indigo was made from blue grass.
Vegetable dyes without chemical processing have been the wisdom of the ancients for thousands of years. But due to raw materials, too extensive processes, and color stability, plant dyestuffs have gone through an extremely difficult path in the industrialization of today's textile industry.
In November 19th, Environmental Resources Committee of China Federation of textile industry Sponsored "China's textile ecological civilization" a great distance Row " Activities entered the Henan Zhongda Hengyuan biological Polytron Technologies Inc. Unlike previous models of ecological civilization, Zhongda Hengyuan did not rely on energy conservation and emission reduction to achieve green production, but through technological breakthroughs, it provided a new development mode for the textile industry. It is worth mentioning that Zhongyuan Hengyuan is not part of the textile industry. The natural pigment extracted from plants has wide application basis in the food field. The first cross-border application in the textile and dyeing industry has provided great imagination for the green development of the textile industry.
"China's textile ecological civilization" a great distance Since its launch, the company has entered into enterprises such as mutual cooperation, all interests, Shandong Lu Tai, Hubei Jialin Jie, Jiangsu Dong Du and so on. Every time, experts are invited to conduct on-site inspection and evaluation, visit the media, and interact with industry leaders and counterparts, thus achieving the "three elements in one" and effectively promoting the excellent practices and technologies of ecological enterprises in the whole industry. Sun Huaibin, vice president of China Federation of textile industry, Cheng Hao, deputy director of the China Textile Industry Association, Cheng Hao, Qiu Hua, Professor of the China Textile Industry and Environmental Protection Commission, Professor Xi Dan Li, Professor of Donghua University, Jiang Tao, director of the five Department of electronics, director of the Ministry of industry and information technology. As well as textile and clothing weekly magazine and other media representatives attended the event.
Using high quality ecological products to meet the needs of beautiful ecological environment
"The modernization we want to build is the harmonious modernization of man and nature. It is necessary to create more material wealth and spiritual wealth to meet the growing needs of the people, and to provide more high-quality ecological products to meet the growing needs of the beautiful environment of the people." Xi Jinping total secretary I talked about that.
The eighteen Party's ecological civilization construction and economic construction, political construction, cultural construction and social construction are included in the "five in one" overall layout of socialism with Chinese characteristics. After the nineteen big, ecological civilization construction continued to advance. Xi Jinping The idea of ecological civilization came into being. It should be said that the importance of ecological civilization in the current economic and social development in China is self-evident. For the textile industry, adhering to green development, accelerating the construction of resource saving and environment-friendly industries, and promoting the construction of ecological civilization in the industry are important actions to implement the "five in one" and the only way for the sustainable development of the textile industry.
In recent years, along with the promotion of environmental protection integrated supply side reform, many textile clusters have issued the policy of no additional capacity, and the textile printing and dyeing industry has also encountered the most stringent safeguards. Sun Huaibin, vice president of China Textile Industry Federation It is said that textile enterprises play an important role in economic and social development, energy conservation, environmental protection and comprehensive utilization of resources as the main body of production and operation. The establishment of ecological civilization from the enterprise level can accumulate valuable experience for the industry and even the whole industrial ecological civilization construction, and can also provide an improvement basis for the green assessment of enterprises. adopt a great distance Such an exploratory, operable and sustainable activity can not only honor the advanced, set up demonstrations, but also promote the outstanding enterprises in the ecological civilization construction of the textile industry, and gradually enhance and expand the cohesion and influence of the textile industry in carrying out the construction of ecological civilization.
The bright and clean production workshop, colorful candy cakes and all kinds of plants stacked in the park show no difference between Zhongda Hengyuan and textile printing and dyeing enterprises. During the visit, reporters learned that Zhongda Hengyuan is a pioneer of the natural pigment industry. After more than 30 years of development, through continuous R & D investment and technological innovation, it has continuously built the soft power of systematic management. It has become a systematic solution enterprise of panchromatic natural pigments from source base construction, extraction, refining processing to application and pharmaceutical production.
As we all know, plant dyes are of quality, safety, control, chemical composition, heavy metals and pesticide residues. At the same time, plant extracts and pectin can be degraded and recycled. If applied to textiles, they can achieve zero emissions in real sense. However, from a food dye enterprise to a textile industry, there are great differences in technology and technology. There is no way to cross the boundary.
use Wen Yanjun, chairman of Zhongyuan Hengyuan biological Polytron Technologies Inc, Henan In other words, the best extraction technology is to go to the application market eventually, and from food to textile, enterprises need to know not just how to extract technology, but how to sink into the application field of textile. For example, because of the sensitivity of plant dyes and the industrialized and standardized production of plant extracts, different batches of plant dyes are inconsistent. The printing and dyeing environment, equipment, water, fabric and other factors in the process of textile production and the pretreatment and finishing of printing and dyeing process will have a certain degree of influence on the color of plant dyes. To this end, this difficult battle, as early as 2005, has quietly started inside the company. The silence of more than ten years has laid the foreshadowing for today's industrialization of plant dyeing in the textile industry.
Wen Yanjun told reporters that enterprises will invest tens of millions of yuan each year to research and development. "Zhongda Hengyuan is able to stand out in the competition with foreign capital, and has been concentrating its efforts on R & D. We must master the core technology and accumulate and precipitate well."
Turning to the difficulties of industrialization in the future, Wen Yanjun made no mention of the fact that the standardization of water values is the biggest bottleneck for the industrialization of plant dyes in the textile industry. Different pH values will affect the stability of color, and the water quality of our country is quite different from south to north or East and West. But she also admitted that technically, this is not a problem, and the most important thing is the change of people's sense of consciousness.
She said frankly, in fact, simply using vegetable dyes does not increase the cost of industrial production. The reason is that the amount of plant dyes is relatively small (except for some dark colors), and can reduce the cost of environmental protection. Many plant materials have their own unique color, but as raw materials come from plant extracts, the factors such as output and scale should be taken into consideration when printing and dyeing raw materials for industrial production. Some products are more suitable for high-end customization and do not support large-scale production.
Add color to life and add health to life.
according to Jin Ziheng, director of marketing department, Zhongyuan Hengyuan biological Polytron Technologies Inc, Henan Introduction, Zhongda Hengyuan subsidiary, Henan dyestuff Technology Co., Ltd. will focus on the dyeing and printing of textile and garment industry in the future with the original intention of health and nature. Its brand "Dyer" will also adhere to the attitude of treating food safety and deep plough in the field of textile plant dyes.
This reporter has learned that Zhongda Hengyuan has repeatedly tested the color fastness of plants to improve its color fastness. At the same time, new raw materials and dyeing processes have been studied to achieve a variety of fabric supply, eight color ranges, more than 300 kinds of colors that can be used to provide customers with more color choices, the introduction of advanced extraction equipment and technology, so that the purity and color price of plant extracts are higher; stable raw material base and source of goods meet the needs of large quantities of plant dyes; many years of industry experience, the dye can be distributed as close as possible to the needs, and provide technical services in textile production.
Jin Heng also told reporters that entering the textile industry, Zhongda Hengyuan will start with indigo dye. He said that Zhongyuan Hengyuan researchers used a strain to produce indigo dye and reformed it to produce a large amount of indigo dye. "Biological fermentation is used to avoid possible contamination in chemical synthesis." He also talked about several advantages of fermented indigo:
First, the yield of Indigo is far greater than that of plant extraction. Indigo is fermented by agricultural wastes such as straw. On the one hand, the cost is greatly reduced and the yield is limited with the increase of output. On the other hand, a lot of plant corner waste is consumed, which is green and environmental protection. It can ensure stable and continuous production, and maintain the quality of dye in the standard range.
Sun Hua Bin It is pointed out that green development is based on the harmony between man and nature as the value orientation. Taking green, low carbon and recycling as the main principles and taking the construction of ecological civilization as the basic starting point, it is an inevitable way to break through the bottleneck of resources and environment. The state is speeding up the establishment of green production and consumption legal system and policy guidance, and the economic system of green low-carbon development is also constantly improving. Energy saving, environmental protection, green finance and other industries continue to grow and grow, and are gradually merging with industrial enterprises. The construction of ecological civilization should not be limited to government On the call, it should be a kind of social behavior of grounding gas, and everyone participates in it, which is very important for achieving the goal and sustainable development of the great power. The application of dyeing technology of Zhongda Hengyuan in textile industry will play a leading role in industry and technology. Its cross-border cooperation and integration with textile industry will bring new ideas and new directions for functional development of textiles, and it is a new attempt of deep cooperation in industry.
It can be said that Zhongda Hengyuan can build together with the textile industry, and it will play a great role and significance in consolidating the international market share under the current trade friction. At the same time, it will also play a key role in achieving the green development goals of the industry. Nowadays, China's textile and garment industry is transforming and upgrading to the "innovation driven technology industry, culture led fashion industry and responsibility oriented green industry", which coincides with Zhongda Hengyuan's plant dyeing. Especially in 2020, the goal of building a strong textile country will be basically realized. In the framework of building a textile power 2011~2020, it is proposed that the textile industry should create new advantages for sustainable development, including technological innovation to reduce pollution emissions and carbon emissions in the production process, to develop recycling technology, and to reduce resource consumption; to develop cleaner production technology as a major task for sustainable development of the industry, and to speed up the whole process of breaking through the industrial chain so as to achieve the goal of reducing emissions and saving water. The industrialization of plant dyeing in the textile industry will undoubtedly help to achieve this goal and task.
During the activity, the experts also took nearly 60 indicators of five modules, such as ecological economy, ecological environment, ecological habitat, ecological culture, and ecological system, to evaluate and evaluate the ecological civilization of textile enterprises. The ultimate goal of evaluation is to incorporate indicators of ecological civilization, such as economic benefits, resource consumption, environmental risks, education and training, social responsibility, into the comprehensive evaluation system of enterprise economic development.
