Academicians talk about the future development of the textile industry

From October 21 to 22, the first "2011 China Textile Academic Annual Conference" will be held in Shanghai. Before the annual conference, the reporter of “Textile and Apparel Weekly” interviewed the academicians of the Chinese Academy of Engineering Yao Mu, Jiang Shicheng, Zhou Xiang, and Sun Jinliang, asking them to talk about the development prospects of the textile industry.

The first “2011 China Textile Academic Conference” aims to “gather academic wisdom and promote textile innovation”. It will invite representatives of textile research experts and scholars from all over the world and representatives of technology-based companies to discuss the development of the textile industry. The theme of the conference will be “Materials Science and Modern Textiles”. The three branch venues for fiber materials, composite materials and technical textiles, and modern textile processing technologies will be set up respectively. The latest scientific research achievements and high-tech incubation forum will be held and an academic awards ceremony will be held.

Textile raw materials will become the focus of attention in the future The raw materials issue has increasingly become a major focus of the textile industry. Recently, the United Nations Secretary-General Ban Ki-moon announced at the “7 billion people action initiative” conference launched by the New York headquarters that the global population will reach 7 billion by October 31 this year. According to the UN’s forecast, the global population may continue to surge. By 2050, this figure will reach 9.4 billion.

In this regard, Yao Mu, an academician of the Chinese Academy of Engineering, stated that after the food issue has become the world’s primary concern, the global cotton field area will be significantly reduced, which will inevitably increase the impact on the textile industry. According to a report from the US Congress, by 2050, the global oil and gas resources will face exhaustion, the global textile industry will face the problem of insufficient raw material resources, coupled with the constraints of labor costs, will certainly give the future development of the textile industry To a great deal of variables. What is the future direction of the textile industry?

As to the issue of where China's textile industry is going in an external environment with limited resources and rising labor costs, Academician Yao Mu stated that there are two development directions:

The first is to develop products with less raw materials and high added value. The first is industrial textiles. The development of industrial textiles will mainly replace non-renewable metal materials, especially steel, followed by apparel and home textiles, and will develop toward high-end and mid-to-high end.

Second, natural fibers must be developed toward saline-alkali land, wasteland, hillside land, etc., and do not compete with the grain to create new varieties. For example, the woody island seaweed found recently in Yunnan can grow on a hilltop of 1,100 meters and three times a year. Including wool, hemp, silk, etc., we must develop new varieties.

Biomass fiber will be used as an alternative raw material Under the premise of limited natural fiber resources, chemical fiber as an alternative resource will have great development, but what kind of chemical fiber is the future development direction of the chemical fiber industry? Jiang Shicheng, an expert on chemical fiber engineering and an academician of the Chinese Academy of Engineering, is one of the major pioneers of China's polyester industry. He discussed his views with reporters.

In the past ten years, China's chemical fiber industry has made rapid progress and currently accounts for two-thirds of the world's chemical fiber production. In the field of conventional and mass products, we have achieved the world's leading position, but there is still a certain gap between foreign countries in terms of high-quality, high-performance fibers. In the future, we must continue to improve quality in conventional products such as polyester filaments and staple fibers to meet the higher needs of the market in terms of functionalization and other aspects.

Talking about the future development trend of the chemical fiber industry, Jiang Shicheng believes that biomass fiber materials will become an important component of alternative chemical raw materials. He said that the current project of the Chinese Academy of Engineering is a strategic study on the industrialization and engineering of biomass fibers. In addition, recycled, renewable, and degradable textile fibers are also the future direction of development. Some companies and universities are already researching and developing, and some are being industrialized. Then there is functional fiber. Du Yuzhou, president of the China National Textile and Apparel Council, proposed to do super-imitation of cotton to make the fiber functionally close to cotton, even exceeding cotton, and proposed to reach the target of 8 million tons of super-imitation cotton during the "12th Five-Year Plan" period. "Now China's polyester industry has 25 million tons of production capacity. If there is one-third of the super simulation, super imitation of cotton, the significance of this is very large." Jiang Shicheng said.

Reducing carbon emissions is a long-term task Textile dyeing and finishing is a link between the textile industry chain and environmental protection, energy conservation and emission reduction. What are the new trends in the progress of science and technology in dyeing and finishing with limited environmental resources? Zhou Xiang, an expert of China's famous textile chemistry and dyeing and finishing engineering and an academician of the Chinese Academy of Engineering, said in an interview with reporters that reducing carbon emissions is a long-term task. The textile industry must pay attention to environmental protection and energy-saving and emission reduction, starting with reducing carbon emissions.

Zhou Xiang pointed out that the increasing temperature on the earth is now caused by the increase of carbon dioxide, because carbon dioxide has the effect of keeping warm. Curbing excess carbon dioxide emissions has become one of the biggest problems facing humanity. Sea level rise is caused by the increase of carbon dioxide. It is predicted that if the atmospheric temperature rises by 4°C over the last century, disastrous consequences will occur. The textile industry is one of the industries with the largest greenhouse gas emissions. The state regards the textile industry as a key industry for energy conservation and emission reduction. Therefore, an important part of the textile industry, the dyeing and finishing industry must increase its emission reduction efforts.

There is an international claim that "carbon tariffs" have been collected. Last year, the leaders of the Ministry of Science and Technology said that instead of letting Americans collect our carbon tariffs, it is better for us to collect them. Therefore, the formulation of a restraint approach has important implications for the reduction of emissions by domestic enterprises. In recent years, the China Textile Industry Association has also vigorously advocated corporate social responsibility, and textile companies are gradually recognizing the significance of this issue. However, compared with developed countries, we still have a gap.

According to statistics from the United States, about 30% to 40% of the water in production is wasted. Therefore, companies should strengthen management so that every employee has a sense of energy conservation.

The Textile Industry Needs Interdisciplinary Talents Sun Jinliang, a member of the Chinese Academy of Engineering, is a renowned expert in composite materials and special textile materials in China. He briefed reporters on the difficulties encountered in the development of the industrial textile industry. In the industrial textile industry, downstream users vary widely. Many industrial textile companies do not understand the downstream needs, and downstream companies do not know how upstream industrial textile companies can help them solve the problems encountered in production.

He said that industrial use is an academic cross-disciplinary subject and academic exchange activities must be carried out regularly to understand the needs of other industries. Other industries also need channels to reflect their problems to the upstream. When you meet, you must ask experts and scholars from cross-disciplines to participate. Professionals from different fields come together to collide with sparks. Otherwise, there will be deviations between products and demands.

He also raised the issue of the industrialization of scientific research achievements. He pointed out that there must be a group of interdisciplinary people who "leapfrogged" out of scientific research to engage in strategic research. “Now the textile industry lacks the talents to do basic work, and it is particularly needed for industrial use. They must have broad knowledge and strategic vision.” He also pointed out that some foreign engineering companies can promote the achievements of scientific research institutions, but There is no similar agency in the country doing such a thing.

For the "2011 China Textile Academic Annual Conference" held in the opening year of the "Twelfth Five-Year Plan", experts expressed that they would promote China's textile scientific research and academic exchange, cultivate and develop strategic emerging industries, and promote textile technology innovation. The pace is positive. At the same time, judging from the lineup of domestic and foreign experts participating in the conference, it is bound to become a gathering of global textile technology elites.
