How Many More Ways To Expand The Circle Of Friends? CV Alliance, "Green Production, Wanli" Enters Yami Technology And Talks About Sustainability.

After more than ten hours of flight, BORIS, Boris of Switzerland, arrived in Zibo in eastern China on June 13th. He would attend a conference here, and 8 hours later he set foot on his way back to Switzerland. BORIS (Boris)'s business in 17 countries around the world, despite the rush of travel, but he knows that as the world's second largest economy in China's huge market opportunities, hoping to make a difference in this broad market.

Of course, he also made a prediction, and more and more enterprises in all walks of life in China will embark on a responsible supply chain management approach. No exceptions. Material Science It is mainly derived from cellulose in renewable woodland trees, which has a long industrial chain and excellent performance in regenerated cellulose fiber industry.

BORIS (Boris) participated in the conference, which is the third stop of "green production Wanli line" sponsored by the green fiber development alliance of regenerated cellulose fiber industry (hereinafter referred to as "CV alliance"): entering Shandong Yami technology and cotton. Spin The conference on industrial chain docking continued from June 13th to June 14th. From China Chemical Fiber Industry Association, China Cotton Textile Industry Association, China Textile Industry Federation social responsibility office, Shandong textile and Garment Association's relevant representatives, as well as CV alliance regenerated cellulose fiber enterprise representatives, cotton textile enterprise representatives and representatives from forestry, chemicals and other stakeholders, a total of more than 50 ginseng.

The union work conference summarizes the series of work carried out by the CV alliance since its establishment for a year and a half, and introduces the follow-up work to be carried out in succession. It focuses on the series of measures adopted by Shandong Yami Technology Co., Ltd. (hereinafter referred to as "Yami technology") in the aspects of energy conservation and emission reduction, and the results achieved. The District conducted a field investigation.

It is worth pointing out that fashion retail brand With the development of supply chain management and raw materials traceable from hair, is it a major trend for recycled cellulose fiber enterprises to make raw material certification? What progress has been made in the process of raw material certification, and what difficulties are facing? What is the next step? The focus of this meeting was discussed in depth.

Textile raw materials

Green outlet for textile supply chain

The raw material for producing regenerated cellulose fiber is natural cellulose. Cotton staple, wood chips, linen and bamboo widely exist in nature, which are rich in natural cellulose. At present, renewable forest trees rich in natural cellulose are the main raw materials. As regenerated cellulose fibers originate from natural and natural degradation of green properties, fiber is receiving more and more attention from downstream.

The CV alliance is also established. The alliance is committed to improving the level of green and sustainable development of the industry, minimizing the impact of regenerated cellulose fiber production and the whole life cycle on the environment, and putting forward the sustainable initiative of "responsibility for nature, from woodland to fashion", and has been involved in 142 textile enterprises. As a member of the industrial chain, it participates in the work of CV alliance. At present, the CV alliance has 13 member units, and the capacity of regenerated cellulose fibers is nearly 3 million 200 thousand tons, accounting for 50% of the total capacity of regenerated cellulose fibers worldwide. The alliance will guide alliance enterprises to take the initiative to shoulder the responsibility of sustainable development and establish a "more responsible" image in the world.

It is worth pointing out that the establishment of a traceability supply chain system is becoming more and more important, driven by the global fast fashion brands such as H&M, based on the green sustainability of the supply chain. Regenerated cellulose fibers chemical fiber Industry and upstream raw materials have entered the vision of terminal brand enterprises and global consumers. These fashionable retail brands begin to trace back to the supply chain system, pursue the traceability and verifiability of suppliers at all levels, and transmit this demand to the upstream textile materials suppliers. For the regenerated cellulose fiber industry, they focus on the sustainable source of raw materials (forest) and the green production of factories. During the meeting, the participating enterprises focused on the sustainability of upstream materials and put forward their respective needs and challenges.

For member enterprises of CV alliance, more and more information has been shown from the needs of customers, and the future green sustainability of enterprises will become an important source of competitiveness. A number of business representatives at the meeting said that in contact with customers, customers would ask whether the pulp they used had passed third party certification. "Our company is a supplier of materials for H&M. H&M has designated us to use FSC certified pulp. Some customers also asked for fiber to be traced to meet the low risk source requirements of other third party organizations. A representative of the participating enterprises said.

However, many members of the CV alliance are troubled by the fact that most of the dissolving pulp used by enterprises is external procurement, but pulp manufacturers are willing to provide relevant information on certification and wood chips and forest sources. "We want the pulp factory to provide information about woodland certification, woodland coordinates and so on, but they refused." A participant said. Moreover, there are many international standards, different standards have different authentication conditions, and even the same standard certification conditions are not static and dynamic, which often makes fiber enterprises feel "unable to touch North".

"The problem of forestry procurement and certification will not disappear because of the more advanced production processes used by regenerated cellulose fiber enterprises. Even enterprises producing the steel are facing the same problem. It can be said that the pulp used by enterprises is a risk whether it comes from tropical rain forests or cold coniferous forests. Therefore, to promote sustainable development, there is no shortcut for member enterprises to establish a responsible image in the world, and we must go step by step. Moreover, the international brand's tracing to the supply chain has begun to incorporate the assessment of carbon emissions in the production process. " A participant said.

The CV alliance is also considering and looking for a long-term solution to the difficulties faced by enterprises. Through organizing and communicating information in the alliance, we hope that the enterprises will grasp the needs and trends of the future development of the industry, and hope to promote the common progress of the industry. Our goal is to move forward together, and all indicators in energy conservation, emission reduction and sustainable development can meet national standards and international standards. We also hope that through continuous efforts, next step, we hope to introduce the alliance's own standards to enhance the voice of the alliance and industry in the global market supply chain. " Jiang Junzhou, vice president of China Chemical Fiber Industry Association, said.

"We can draw up our own standards in accordance with international standards and indicators. In this way, when our enterprises discuss business with international customers, they can issue our own standard certification. Our industry has such a large scale in the world, and it has such a foundation. Of course, this needs a process. A participant told reporters.

Production process

Yami technology has achieved remarkable results in energy conservation and emission reduction.

This CV alliance "green production Wanli line" entered Shandong Yami Technology Co., Ltd. is the third stop of the event. Previously, the first stop was Tangshan Sanyou group Xingda Chemical Fiber Co., Ltd. the second stop was the Sai Deli (Jiujiang) company. The CV alliance's "green production million miles" campaign was launched in June 2018. It aims to provide members with a platform for energy saving and emission reduction, so that different enterprises can learn from each other's specific technologies in terms of "three wastes" management and so on.

Located in the high efficiency eco economic zone around the the Yellow River Delta, the Yami technology in Shandong Boxing Binzhou Industrial Park, founded in 2005, is a subsidiary of Bohai industrial group. It is also the largest regenerated cellulose fiber production enterprise in Shandong province. The company has 6 production lines, one phase has 2 lines, it was put into operation in August 2007, and there were 4 production lines in the two phase, which was put into operation in June 2012. At present, the annual production capacity of Yami technology regenerated cellulose staple is 280 thousand tons, and has 200 thousand tons / year of sodium sulfate and 23 thousand tons / year of 70% sodium sulphide production capacity. Yami joined CV alliance in March 2018 and is one of its first member enterprises.

The reporter saw in the drying workshop of Yami technology, the huge silver drying equipment was directly discharged from one side of the workshop to the other side. The equipment is about two meters high, two meters wide, and the length reaches tens of meters. It looks very spectacular. The temperature inside and outside the equipment is very high, and white and soft staple fibers like cotton are rolling back and forth in the equipment. After drying, the fibers will be sent to the next process. According to reports, these equipment imported from abroad, the degree of automation is relatively high, single line capacity is larger, about 60 thousand tons.

Liu Runzhang, general manager of Shandong Yami Technology Co., Ltd., general manager of safety and environmental protection department, said that after joining the alliance, the company aims at CV level I requirements, starting from raw materials, production processes and products, and continuously improving the company's green development and energy saving and emission reduction level.

In terms of sewage treatment, Yami technology is currently using the technology of "physicochemical + biochemical", mixing and neutralizing wastewater, adjusting the pH value to neutral. After physicochemical precipitation, it enters the aerobic biochemical system. After settling by the two sedimentation tank, it enters the municipal pipe network and is discharged by the municipal sewage treatment plant. The company also has standard sewage outlets and installed online. Testing Equipment.

In terms of waste gas treatment, Yami technology uses the technology of alkali washing + adsorption to recycle the process tail gas or make by-products. According to the introduction, the system has advanced process design, mature technology and DCS centralized control, which can realize the recycling of carbon disulfide. Reporters did not see the unusual smell when they visited the Yami technology factory.

Liu Runzhang also introduced that the company uses lithium bromide unit to recover and heat the waste heat, and reclaim the heat of the waste water from the straight row row, and drive the new lithium bromide refrigeration unit, thereby reducing the cooling capacity and saving energy. In addition, Yimi technology has replaced the old roots blower by implementing the magnetic levitation fan transformation. The new magnetic levitation fan is driven by high speed permanent magnet motor directly, which is completely non-contact, frictionless, low noise and maintenance, and the energy saving effect is very obvious.

According to the introduction, Yami technology has passed the certification of FSC and CFCC/PEFC production and marketing chain in September 2018. In October 2018, it passed the highest level (level three) certification of the International Environmental Protection Textile Association (OEKO-TEX) STeP. In November 2018, the MADE IN GREEN by OEKO-TEX label was applied in combination with STeP certification and standard 100 certification. The label can prove that the company's products not only passed the detection of harmful substances, but also can be produced in a sustainable way, which is welcomed by downstream customers.

"Our company's unit product energy consumption level, water consumption, and output of sodium sulfate are superior to" I "benchmark value of the evaluation index system for cleaner production of regenerated cellulose fiber manufacturing (viscose method), and it represents one of the leading enterprises of cleaner production in China. Next, the company will continue to improve the level of green development, and intensify efforts to develop green products, such as colored silk. Liu Runzhang said.

Downstream application

Products and technological innovation bring broad prospects.

The second day "cotton textile industry chain docking meeting" is also a highlight of this event. At the meeting, the two spinning enterprises of Yin Shi Lai Group and Dezhou Hengfeng group introduced the experience and feelings of using recycled cellulose fiber for yarn and textile development respectively. The participating enterprises also discussed the new product development thinking of regenerated cellulose fiber in the next spinning and weaving process, and the key points for further improvement.

Dezhou Hengfeng group is one of the leading enterprises in the field of innovative yarn research and development in China. It has formed a variety of yarn structure mainly based on multi varieties, functional fibers and cellulose fibers. In recent years, Dezhou Hengfeng has made extensive use of regenerated cellulosic fiber materials, including viscose fiber, modal, Tencel, alginate fiber, chitin fiber, corn fiber and so on. Many CV alliance members of Tangshan Sanyou, Sai Deli, Yami technology and so on are raw material suppliers.

According to introduction, Dezhou Hengfeng currently uses about 50 thousand tons of viscose fiber every year, and about 20 thousand tons of modal and Tencel are used. The yarn used in regenerated cellulose fiber is very rich, including pure viscose fiber, viscose fiber and cotton two components. Blending Varieties, viscose fiber and cotton, acrylic, polyester and other multi component blended varieties, viscose fiber and functional polyester or acrylic fiber blended varieties, functional viscose fiber and cotton, polyester blended varieties.

Zibo yililai Textile Co., Ltd. currently produces 230 thousand spindles per year, and has 1054 shuttleless looms (including 290 high-speed jacquard machines). The annual output of fabrics is about 85 million meters. The company widely uses various functional, differential and new fibers such as cotton and Tencel, viscose fiber, copper ammonia fiber, acetate fiber, bamboo fiber, corn fiber, milk fiber and so on.

Zhang Xuewen, from Yin Shi Lai Group, introduced the series of products developed by the company using regenerated cellulose fibers. cowboy It is used in many fields such as home textiles, woven shirts, woven trousers and colored spun fabrics. The regenerated cellulose fiber purchased by the company is suitable for spinning over 60 or more high count yarns. The knitted and woven fabrics produced by this kind of high count yarn have the advantages of good softness, good pilling, good shrinkage and small shrinkage. After dyeing, they are of high colourful color and high color fastness. They can meet the quality requirements and unique styles of the international textile products, and the products are widely used in the field of high end knitting. In the field of home textiles, regenerated cellulose fibers used by Yin Shi come from pure spinning or blending with other fibers. The yarn has good spinnability, which can get high quality yarn and finished fabrics, and the finished products are soft, bright, bright, and comfortable. At the same time, the shrinkage of products is small and stable, making production easier to operate and control.

Zhang Xuewen also introduced that Yin Shi Lai used regenerated cellulose fiber to conceive new fabric structure and properties, and developed new products. The train of thought includes: developing multicomponent blended fabric, interwoven fabric, developing different warp, irregular weft, irregular shape, different fineness and different shrinkage fabric; developing fancy yarn fabric; developing thin and thin fabric; developing complex structure, changeable fabric and developing new nature. New functional fabrics, such as sweating, hygroscopic and quick drying fabrics, antibacterial or antibacterial fabrics, UV resistant fabrics, antistatic, electromagnetic shielding fabrics, etc.

However, in combination with the practical experience, the cotton textile enterprises participating in the conference also put forward many suggestions for further development of regenerated cellulose fiber enterprises, including: increasing efforts to develop high wet modulus and functional products; increasing strength to develop non-ferrous products, providing more color choices for spinning mills; continuing to improve the stability of batch quality, reducing chromatic aberration, moisture regain and times. Long, super long, oiliness, silk and so on.

From the perspective of long-term development, we are still generally optimistic about the broad application prospects of regenerated cellulose fiber products in the future.

"Eco" or environmentally-friendly, high-tech functional and safe products will be the key development direction of the international textile market in the future. Regenerated cellulose fibers have the natural characteristics and good properties of synthetic fibers. In recent years, regenerated cellulose fibers are increasingly favored by downstream brands. The application of new technology has brought about functional diversity, and has made great changes in its comfort. Therefore, its future market prospect is very broad. A representative from the spinning industry said.
