Three Difficulties In Developing Recycled Fiber

At present, with the production of recycled fiber fabrics and clothing More and more people are accepted, and natural fiber and synthetic fiber materials are becoming increasingly scarce. The development of domestic regenerated fiber has also ushered in new opportunities. Some enterprises already have the leading international production technology and equipment. But on the other hand, the development of domestic recycled fiber is still facing many bottlenecks, and the road ahead is not smooth.

　 Opportunities are coming and prospects are good.

According to statistics, China in 2011 Spin The consumption of raw materials has reached 41 million 300 thousand tons, and experts predict that if new oil fields are not found, the oil resources, which are the main raw materials of synthetic fibers, will be exhausted before and after 2050. China's crude oil imports have a high degree of dependence. How to reduce dependence on fossil resources has become a very prominent practical problem. Moreover, with the serious problem of grain and cotton competition in China, the natural fiber resources are limited, and the expansion of population makes the demand for fiber increase. The shortage of textile materials is becoming more and more serious.

The raw materials of regenerated fiber can be divided into two categories, one is waste polyester bottles, the other is leftover leftover bits and pieces. clothes 。 At present, the annual stock of waste PET bottles in China is nearly 3 million tons, and the annual storage of waste textiles has reached 26 million tons. Handling and burying these wastes not only cost a lot of space and capital, but also cause huge environmental pollution. How to turn these wastes into treasure has become a common concern of the government and enterprises, and recycled fiber can take this opportunity to develop.

Some enterprises have seen the economic and social benefits of developing recycled fiber. "Compared with the original polyester fiber, each production of 1 tons of recycled polyester fiber can replace 6~8 tons of virgin oil. It can use 2.4 tons of polyester plastic raw materials from the landfill to save nearly 3 cubic meters of landfill space. Compared with the production of traditional polyester fiber products, it saves 43.6 tons of water resources and reduces the carbon emissions of 3 tons of refuse incineration process, and the effect of energy saving and emission reduction is very obvious."

Yangzhou Tianlong auto interior Fiber Co., Ltd. Yang Jian told reporters.

In addition, the use of recycled materials has become the need to protect the environment, and has been highly valued by the state, and has played a positive role in guiding the related enterprises. As a strategic emerging industry, energy conservation and environmental protection is highlighted in the national "12th Five-Year plan". As an enterprise, we should consider the strategic plan for sustainable development. In addition, the concept of utilizing waste resources is gradually changing, so we can confirm that the development opportunities and prospects of recycled fiber in China are optimistic. He Wei, general manager of Zhejiang beauty new materials Co., Ltd. is full of confidence.

　　 Flourishing development sees clues

Since 1950s, developed countries have begun to study the methods of recycling and reusing PET. So far, many large companies and research institutes in the world have invested huge manpower and material resources in this area, some of which have been commercialized. Today, some well-known international brands have joined the ranks of promoting the development of recycled fiber products. For example, Nike and Adidas provided the uniforms for 9 national teams in Holland, Brazil and the United States in the 2010 FIFA World Cup in South Africa, which were obtained through recycling of waste polyester bottles. Wal-Mart Store Inc made clear in 2010 that in the next 5 years, zero discharge requirements for waste should be implemented in its supply chain.

Statistics released by the national development and Reform Commission in September 2011 showed that in 2011, the production capacity of regenerated polyester fiber in China was 6 million tons, and the actual output was nearly 4 million tons, accounting for 80% of the world's total output. It can be seen that China has become the first largest producer of regenerated fiber polyester fiber. Especially in the areas of Jiangsu, Zhejiang and Shanghai, there are many factories for the recovery of polyester bottles and a large number of processing enterprises for recycled fibers, and gradually formed a certain scale of production. Some of them have sprung up and have reached the advanced level in the world in terms of production technology and management level.

For example, Zhejiang beauty New Material Co., Ltd. is famous for its chemical recycling and regeneration of polyester filament. Through the introduction of the world's top ECO CIRCLE recycling system, we can achieve a closed cycle from clothing to clothing, and its chemical recycling process can achieve new production of endless polyester under the premise of constant quality. On the one hand, it overcomes the shortcomings of regenerated polyester fiber, such as physical production, low purity, large quality limitation and difficult to adapt to the requirements of high-end clothing. On the other hand, the "ECOCIRCLE" circulation system has a great contribution to the earth's environment. "For example, the recycling of 300 T-shirts (about 1 tons) will reduce energy consumption by 84% compared to the production of polyester raw materials from oil, equivalent to the energy consumed by a family in one year, or about 6 kilocatas, while CO2 emissions will be reduced by 77%." He Wei, general manager of Zhejiang beauty New Material Co., Ltd. For example, the regeneration of differential fiber production, some enterprises have been able to meet the needs of the international market, and are moving from low-end fillers to high value-added fabrics such as high-end fabrics. Some enterprises have developed high-end regenerated products independently.

Fiber products. Shanghai Defu Lun Chemical Fiber Co., Ltd. focuses on the development and application of regenerated differential fiber. It can not only produce regenerated differentiated polyester fibers that meet the needs of the international market, but also its coffee carbon fiber, regenerated cooling fiber and regenerated super Imitation cotton fiber has been widely used in spring and summer fashion, underwear, jacket, sportswear, casual wear, home textiles and other textile fields. Yang Weizhong, general manager of the company, said: "we will extend the industrial chain of recycled polyester fabrics with the core of fiber enterprises, which will greatly increase the profits of enterprises. Only by forming a circular economy industrial chain of regenerated polyester industry, can we grasp the whole production chain process and strive to develop end products and form a coherent industrial chain so as to expand the market share.

For example, some enterprises are building large-scale circular economy industrial parks for R & D and production of recycled fibers. Haiyan Haili environmental protection Fiber Co., Ltd. has the leading production technology of regenerated FDY filament. It mainly develops, produces and sells recycled polyester raw materials and differential regenerated polyester filament. At present, circular economy industrial park is developing. Its economic and social benefits are enormous. Chen Jie, general manager of the company, said: "we are building Haili circular economy industrial park from 2012. We expect to put into operation in July this year. After the project is completed, the annual output value will reach 10 billion yuan, and the annual profits and taxes will be 1 billion yuan, with remarkable social and economic benefits. Our company is committed to building the most complete recycling chain of recycled polyester resources in our country." {page_break}

　 Challenges and difficulties

As the largest producer and consumer of fiber products in the world, China is still carrying the heavy task of upgrading the industrial chain and value chain from the low end to the high end in the innovation and transformation of the recycled fiber market, and there are many challenges ahead.

First of all, many enterprises still focus on the production of low-grade fillers and non-woven fabrics, and lack of development in the production of high value added products such as high-end fabrics. "In general, China's regenerated polyester fiber products lack systematic and continuous investment in technology, talent, equipment, product development, market development and so on. The management level is not high, resulting in discontinuous production and difficult to form large-scale production. Moreover, the products are still mainly made of low-grade cotton, filler and non-woven fabrics, and lack of development of high value-added products such as functional filament products, high-grade knitted fabrics and high-grade home textile fabrics needed in the international market, which can not form a benign circular industry development trend. He Wei said in an interview.

Second, the low threshold of access to recycled fiber production enterprises has led to various kinds of businesses in the industry. Zhao Li, deputy general manager of Hangzhou Best Chemical Fiber Co., Ltd., expressed his concern: "at present, there is no uniform industry standard for the production of recycled fiber in China, some enterprises are irresponsible to society, and there are no suitable industry management measures for regulatory authorities. These are the outstanding problems facing the regenerated fiber industry. A few days ago, our recycled fiber enterprises are also meeting to discuss how to transform and take the lead in promoting the introduction and implementation of the industry standards. Of course, this also requires the guidance of relevant departments and media.

Thirdly, the concept of mass consumption needs to be changed. Reporters interviewed a number of consumers randomly, and found that most people are still unable to accept the new consumption concept of "waste recycling resources consumer goods", and think that the safety and hygiene level of recycled fiber products is inferior to that of native fibers. "In foreign countries, because of the recognition of the concept of environmental protection, consumers have a high degree of recognition for recycled products. In China, consumers think that recycled products are not good, they are rubbish. This concept is also a major challenge for the development of recycled fibers. If there is no authoritative department to set standards to regulate and guide consumers, Chinese consumers will have at least 50 years to change their understanding of regenerated fiber. Zhao Li's remarks also confirm the reporter's interview investigation.

Moreover, Zhao Li is worried that our country lacks relevant laws and regulations at present. For example, laws and regulations do not specify that some products must use recycled raw materials, which is explicitly required abroad.

Faced with the opportunities and challenges of China's regenerated fiber industry, entrepreneurs in the vicinity expect that the government departments can strengthen policy support, formulate unified industry access standards as soon as possible, and also hope that social media will appeal more frequently to guide consumers to change their concepts. Only in this way can China's recycled fiber industry flourish.
