Recycling And Recycling &Nbsp; Hard Nirvana Of Textiles

TBIS2011 International Conference, Yao Mu, academician of the Chinese Academy of engineering, said that textile recycling and regeneration is one of the directions for the future development of the world textile industry.

regenerate textile This topic, once neglected and neglected, is very thought-provoking. Green, energy saving, environmental protection? These labels are the connotation of recycled textiles that can be felt from the name. From the beginning of material recovery, the earliest form of regenerated textiles is the recovery of cotton and recycling of polyester fibers, and technological advances bring about various regenerated cellulose fibers. Low carbon economy requires "carbon from the cradle to grave" to restrict production and circulation. Resources With the consumption of energy, recycled textiles have realized the true recycling from cradle to cradle. Low carbon The ultimate return.

How to regenerate textiles? It is usually defined that the textile produced after the recycling of waste materials in production or after production is regenerated textiles, and the more vividly expressed is the recovery of all kinds of fiber textiles and then the processing of new textiles. For example, all kinds of regenerated cellulose fiber textiles, which are popular in the market, are typical recycled textiles. For example, "cola bottle clothing" and "woven bag refurbished schoolbag" appeared in some shows are regenerated textiles. A more straightforward explanation is: after wearing a piece of clothing, a garment is returned to the factory and transformed into another garment through a series of processes.

In some developed countries, this has already been done well. Textile recycling and recycling in the United Kingdom, the United States, France, Italy and other developed countries is very common. China also started calling for textile recycling and recycling about 10 years ago, but failed to carry it out. Because the cost is too high - first of all, the old clothes must be collected, sterilized, cleaned, decomposed, and processed into textiles after the previous process. This process increases the cost of recycling and reusing textiles more than the production of new products. It is necessary to sell the company at a higher price to survive and profit. However, the performance of recycled fibers is definitely lower than that of the first use. To spend more money on things with poor performance, the "cost performance ratio" is not high.

The US Congress and the European Parliament have decreed that the price of textile products can be raised by 10% compared to ordinary textile products with the logo "regenerated". At the beginning, people did not buy it, but after 22 years of publicity and promotion, in order to protect the environment and save the earth, consumers now gradually recognized recycled textiles. Many people saw clothes with "recycled" labels willing to pay for them.

The EU also revised the Waste Framework Directive program in 2008, aiming to enable EU public and enterprises to promote more environmentally friendly regeneration of all kinds of resources. At present, the use of recycled materials is favored by the textile and garment industry in Europe. Many world-renowned brands and international buyers have embarked on developing or purchasing large quantities of recycled textiles, such as Jimtex Yarns, manufacturer of environmental recycled fiber and yarn, Japanese Imperial textile company, British clothing retailer, Marsha general store and American department store retailer WAL-MART. I wonder when the recovery and regeneration of textiles will become a common thing in China.

China is also calling for the use of recycled textiles for nearly 10 years, but there is still a big gap between its popularity and those in Europe and the United States.

Yao Mu said that at present, only the PLA's military uniform is recycled and regenerated in large scale. There is a small episode: 400 thousand of the PLA officers and soldiers are retired from service every year, and now they are no longer allowed to be taken away from the army. Once there were ex servicemen working in Africa, wearing airplanes and wearing military uniforms. The local government thought that a military riot was going to happen, which almost caused conflicts and was resolved by the Ministry of foreign affairs. Therefore, the PLA General Logistics Department prohibits soldiers from taking out military uniforms and decommissioning military uniforms, and costs 6 billion yuan a year for this purpose.

As a major exporter of textiles, China's textile production and export enterprises are stepping up R & D and production of recycled textiles in order to promote the export of textile products and conform to the trend of international green trade. However, as Dr. Jiang Hong, SGS textile technology expert pointed out, due to technical and cost reasons, some renewable resources have caused a lot of energy waste and environmental pollution in the production process. As a result, recycled textiles just wear a "green" coat, and have not fully realized the real sense of environmental protection. For example, a large number of discoloring wastewater (including machine chlorine) have been produced in the textile processing process in some areas, and incineration of non fading and invalid waste cloth corner materials has resulted in more waste of water resources and greater environmental damage.

Such a "green" is not desirable. Although the cost and recovery of textiles can be really costly, it will still be the way forward for environmental protection. Relying solely on the strength of the enterprise or industry, it is difficult to bear the hope that our society can create a truly green textile consumption environment.
