Energy Shortage, Textile Industry To Find New Raw Materials

One friend complained, "it's said that this winter will be cold... Go to the mall and turn around and try to buy a down jacket for the winter. The price of this gorgeous, cheap seven hundred or eight hundred is usually over 1000 yuan. "This winter is really no money to buy a down jacket, so let's warm up with everyone." since the winter, similar topics have always resonated with some netizens.

Some people last year in a brand chain store to see the down jacket is 299 yuan, did not buy; this year to see similar products, "cry" - 499 yuan...

The textile industry has seen changes more intuitively. According to the news from the China feather and down industry association, the price of raw materials in the down garment industry is "amazing."

Wang Rui, Dean of the Textile Institute of Tianjin University of Technology, pointed out in an interview with our reporter that the rise in clothing prices was mainly due to the rise in prices of raw materials such as cotton (25225, -1225.00, -4.63%) in recent months.

The latest industry warning issued by China Cotton Association points out that domestic and international cotton prices have risen rapidly and substantially, and hit the highest level in history. In October 27th, China's cotton import index reached 152.47 cents / pound, an increase of 70.29 cents / pound, up 85.5% from the beginning of the year, at 82.18 cents / pound.

China Cotton Association cotton farmers cooperative branch pointed out that China's total cotton output has declined slightly this year compared with last year, while spinning output and textile and garment exports continued to grow.

Recently, the news of Wenzhou's "real estate group" transformed into the "fried cotton ball" news, which made the public have a deeper impression of the continuous high cotton price. However, it is not easy for ordinary people to think that oil prices will also affect a little bit of themselves.

For Professor Zhang Jianfei, Secretary of the Party committee of Tianjin Textile University, every round of rising oil prices will remind him of his family's clothes, shoes and hats. He said that the proportion of chemical fiber clothing in clothing industry is increasing, and chemical fiber is refined from petroleum. When oil resources become scarce, the production of chemical fiber products is bound to be affected.

Wang Rui told reporters that with the depletion of oil reserves, chemical fibers are decreasing, which is happening. The textile industry is trying to find various fiber materials to replace chemical fibers.

　　 oil price The nerve involved in the textile industry is embodied in the energy consumption in the production process, and more importantly, it is reflected in the supply of raw materials. In November 22nd, at the second academic forum of the Chinese mainland and Hong Kong and Taiwan textile, held at Tianjin University of Technology, Yao Mu, a textile material scientist and a member of the Chinese Academy of engineering, pointed out that because of the gradual depletion of petrochemical raw materials, the supply gap of raw materials for textile fibers is very large, and "we must find other resources".

Chemical fibers are the main force in textile fibers. In 2009, the total output of natural fibers (cotton, wool, hemp, silk and so on) was 27 million 600 thousand tons, and the total output of chemical fibers was 46 million 250 thousand tons. By 2050, the raw material needed for textile fiber is expected to increase to 2.5 billion tons.

But in 2050, global oil is likely to dry up, which is November 8th. U.S.A Two economists from University of California at Davis published their predictions.

Yao Mu believes that this is not alarmist, so the future gap in the supply of raw materials for textile fiber is very large. Broadening textile fiber materials is the task facing the textile industry at present.

Once the chemical fiber is lost, no matter how hard efforts to increase the output of natural fibers, it is also difficult to meet human needs. Moreover, the production of raw materials such as cotton will not expand indefinitely. Yao Mu pointed out that according to the UN's forecast, the global population will reach 9 billion 200 million in 2050, the population explosion will cause food supply shortage, and the limited cultivated land will be more used for planting grain.

Yao Mu suggested that we should make full use of natural conditions to cultivate new varieties and plant natural fibers in areas such as saline alkali land, wasteland and hillsides.

"China has launched a work to cultivate new cotton, hemp and mulberry varieties and use transgenic technology." He said.

Yao Mu said that the silkworm mulberry leaves, sugar cane bagasse, corn (2274, -37.00, -1.60%) stalk and other waste crop resources, and bamboo, seaweed, crab shell and dried shrimps can be extracted from cellulose, which is used as raw material for regenerated fiber. For example, seaweed can be extracted from alginate after being extracted iodine and made into sodium alginate for spinning.

According to his introduction, the annual output of cellulose produced by acetic acid bacteria in China has reached 25 thousand tons, which is extracted from the common vinegar after "white hair".

Yao Mu also believes that while developing new non cotton fibers to replace cotton fibers, we should make full use of the existing waste textiles. More than 30 million tons of waste textiles are produced every year. Environmental Science Contaminants. Of course, recycling is difficult and costly. At present, a small number of enterprises have entered the market for the reuse of waste textiles. Some enterprises have sliced and spinning old plastic (11610, -610.00, -4.99%) bottles and made them into garment fabrics.

Fujian Haidong Qingxin new material group is such an enterprise. Some of the non-woven fabrics produced by the company can be used to make clothing and footwear products. Nian Weicheng, CEO of the company, said that the raw materials of the company are basically discarded plastic bottles.

According to Yao Xingchuan, Professor of molecular science and Engineering Department of Taipei University of science and technology, in Taiwan, recycling of discarded beverage bottles or polyester waste yarn or waste cloth into textiles or garments is the most widely known form of environmental regeneration in textile and garment industry.

　 Professor Yao Xingchuan said that Taiwan does not produce any natural fibers that can be woven and industrialized, almost entirely by imports. But there are several chemical fiber factories in Taiwan collecting plastic bottles, slicing and spinning. Many wastes can be used in textile products in various ways, but sometimes the cost of recycling is relatively high, which requires the encouragement of corresponding policies and regulations.
