Development Of Skills And Environmental Protection Technology In Textile And Garment Industry

Act as Spin Great powers, our textile enterprises have been deeply aware of not developing energy conservation. environmental protection Technology in the future market It will be difficult to occupy a place in competition.

Mineral water bottles can be turned into fabrics. In many people's eyes, this is unbelievable. However, in the textile and garment industry, waste recycling is in the ascendant.

Guo Feng, general manager of Wuxi Heng no Knitting Co., Ltd. told the author that the HANUO environmental recycled fabric they produced was recycled mineral water bottles, waste polyester polyester clothes, fabrics and textile waste silk. Through the environmental re polymerization procedure, the polymer was decomposed into two monomers, then distilled and refined into pure polyester polymer, then spinning, weaving and dyeing into fabrics, and finally processed into garments. "These recyclable raw materials are not limited in use and can be recycled indefinitely."

Low carbon is no longer a slogan. As a big textile country, China's textile enterprises have been deeply aware that not developing energy saving and environmental protection technology, it will be difficult to occupy a place in the future market competition.

　　 Environmental fabric

World Expo, Shanghai has just come to an end. In this feast, the T-shirt worn by volunteers shows the technological progress of China's textile industry, which is made of new cool material Flycool, adding inorganic mineral composite powder. It has the effect of instant cool feeling and moisture absorption and quick drying.

"When the fabric is in contact with the skin, it will produce a cool feeling of 1 degrees ~2 degrees Celsius, which can raise the air conditioning temperature of the wearer in the environment of 1 degrees C, which will save the electricity charge of 3%~5% and reduce the carbon emission of 0.66kg." Hu Yongqin, general manager of the Taiwan textile and industrial company, which produces the fabric, said, "if you put it in more factories, what kind of a number will it be?"

In fact, the 2010 China international textile fabrics and accessories fair, which was held in Shanghai not long ago, has also become a stage for the competition of environmentally-friendly fabrics.

Wuxi Heng Nu knitting company has introduced HANUO environmentally friendly recycled fabric, which can reduce energy consumption by 64% and reduce carbon dioxide emissions by 60%.

Haitian light textile group has introduced Ecorona environmental recyclable fabric, which will be recycled from waste polyester fabric or polyester waste, spinning and weaving. Another Sorona corn fiber and blended fabric can replace oil extraction fiber, which is much less than that produced by conventional products.

The IOD lightweight fabric displayed by Wujiang Fuhua weaving company is woven from recycled resources. The total weight of a garment made of this fabric is less than 50 grams, which reduces the utilization of resources by developing lightweight fabrics.

　　 Technology provides motivation

Behind all the low-carbon and environment-friendly clothing is the inexhaustible R & D power of enterprises.

To promote low carbon development in textile industry, sizing is a difficult problem, because it not only consumes a lot of food, but also requires a lot of water for desizing. Wuxi natural textile company has developed no slurry technology and solved this problem in one fell swoop.

Zhu Guomin, the chairman of the company, said that according to the traditional process, the 1.5 meter door size would need to be calculated by 3 tons of water per 100 meters. 400 thousand meters of fabric could save 12 thousand tons of water every year in Desizing. Moreover, the process also avoids the production of desizing wastewater and plays a positive role in protecting the environment. "At the same time, this technology saves the sizing machine and saves the workshop and manpower." Zhu Guomin said to the author.

Printing and dyeing can be regarded as the most serious pollution in the whole production chain of textile industry. The cold transfer printing technology recently introduced by Gage (China) dyeing and finishing company may represent the future direction of printing and dyeing.

It is understood that the technology can achieve maximum use of dyes, no residue, no pollution, so that dye consumption savings of 40%. Compared with the traditional printing, it can save 2/3 of the water consumption, and the recovery and utilization rate of the discharged water is also 90%. At room temperature, printing at room temperature and fixing at room temperature can save 65% of energy.

The use of information technology has opened another window of low carbon transformation for textile enterprises. Hangzhou open source computer technology company provides the overall solution of printing and dyeing digital factory, which can realize high-speed intelligent sizing and residual pulp reuse, and effectively reduce the use of dyes and auxiliaries.

　 Low carbon cycle development

From fiber to fabric to clothing, many textile enterprises strive for energy conservation and emission reduction in a single link. Some large enterprises rely on their own resources to establish an environmental protection industrial park to accelerate the process of low-carbon development.

An Li Fang (Shandong) Industrial Park is a model of low carbon and environmental protection in the industry. As the first environmental protection industrial park in Shandong Province, the park is a demonstration project of integrated technology of ground source heat pump and energy saving industry. Refrigeration and heating system use renewable resources to save energy by more than 70%, while reducing air pollutants such as carbon dioxide emissions.

In October this year, the Black Peony eco industrial park, which integrates production, marketing and R & D centers, was put into operation. Lu Qing, assistant president of black peony group, told me that the comprehensive energy consumption and carbon dioxide emissions of 10000 yuan GDP in this industrial park are better than those of the national eco industrial demonstration park. The centralized disposal rate of hazardous waste, the centralized treatment of domestic sewage and the harmless treatment rate of domestic refuse reached 100%.

It is reported that the black peony group has invested 250 million yuan for technological transformation, and actively adopts new technologies, new technologies and equipment for energy conservation and environmental protection, so as to improve the efficiency of resource utilization. They invested about 25000000 yuan to build a sewage treatment station and a river purification treatment station with a daily capacity of ten thousand tons of sewage. At present, it has reached 2000 tons of daily water consumption and 600 thousand tons of water saving per year. With the improvement of the equipment and supporting facilities in the follow-up Park, it is estimated that the amount of reuse will be increased to 60%.

In addition, the comprehensive office building fully introduces the water cool storage and energy saving air conditioning, balancing the load of the electric network, and the new factory buildings use high efficiency and energy saving light source. In order to promote the level of cleaner production, black peony also eliminated 4 high energy consumption coal-fired boilers, used centralized heating in the thermal power plant of the park, eliminated 1 coal-fired heat transfer oil boilers, and directly used natural gas combustion to finalize the fabric.

"The creation of industrial parks is to achieve the development of low carbon cycle." Lu Qing said
