Green Production Test Competitiveness

"The quality of denim made by us is almost the same as that produced in Turkey. But why does their cloth sell for us $seven or eight per metre and our cloth can only be sold for us $two or three per metre?

Where is the gap?

The question raised by Yang Bin, deputy general manager of Foshan Zhixing textile and garment company, aroused heated discussions among delegates attending the 2011 national denim industry annual conference.

Yang Bin believes that in the past, enterprises mainly focused on improving product quality, but not enough attention was paid to energy saving, environmental protection and cleaner production.

His views have been recognized by many enterprises.

"Green environmental protection and cleaner production" is the theme of the annual national denim industry conference.

How to apply

Increasingly urgent ecological requirements

In the previous stage, Greenpeace, an international environmental group, released a report entitled "the poison of fashion - the global water pollution survey of clothing brands". The survey showed that 14 global clothing brands such as Nike, Adidas and Lining failed to effectively solve the problem of water pollution caused by the discharge of toxic and harmful substances by suppliers.

Lining, Nike, H&M and other 14 garment enterprises and related suppliers have been pushed onto the cusp.

Regardless of the facts, this event once again reminds textile enterprises to attach importance to energy conservation, environmental protection and cleaner production.

In recent years, a number of excellent enterprises have begun to attach importance to energy conservation and environmental protection. By introducing advanced equipment and adopting new raw materials and new technology, environmental indicators have reached or surpassed domestic and international standards.

Relevant government departments also issued a number of support for energy saving, emission reduction and backward industrial policy.

Although these efforts have made great achievements, many enterprises, especially small and medium-sized enterprises, do not attach importance to clean production of environmental protection.

In August 12th, the European Commission's non food quick warning system issued consumer warnings to Chinese women's jeans.

The notification country of this case is Poland. The jeans are blue and the style / type is coded as OM215.

Because the formaldehyde content of the jeans is as high as 180mg/kg, there is a risk of chemical sensitivity or poisoning. The products do not comply with the relevant EU legislation.

At present, the competent authorities in Poland have ordered the goods to be withdrawn from the market.

The case that happened not long ago alerts enterprises that they can no longer attach importance to clean production of eco environmental protection.

According to Lin Li, manager of eco Products Certification Department of Tianxiang group, there is no uniform definition of eco textiles so far.

Generally speaking, the concept of eco textiles involves four links: renewable or reusable resources; harmless to the environment and human health during the production and processing of products; the products are harmless to the human body or the environment during the use of the products; the products will not cause new pollution to the environment after the products are discarded.

She reminded the denim manufacturers to focus on banned azo dyes, APEO, formaldehyde and heavy metals.

Raw materials used for denim fabrics: pure cotton, wool, viscose, polyester, Tencel, linen, silk, dyestuffs involved in dyeing, auxiliaries used in cowboy processing, and other problems may not meet the requirements of environmental protection.

For example, heavy metals may exist in reactive dyes, and direct dyes can cause carcinogenic aromatic amines. Additives may produce residues such as APEO and formaldehyde.

The EU REACH regulations, which came into force in June 1, 2007, have received wide attention. According to REACH regulations, substances listed in Appendix XIV are not authorized to be sold and used.

These substances include carcinogenic, mutagenicity and reproductive toxicants, persistent, bioaccumulative and toxic substances and high persistence, high bioaccumulation substances and similar substances, collectively referred to as highly concerned substances (SVHC).

As of June 20, 2011, the proposed SVHC list of candidates included in Appendix XIV contained 53 substances, of which 7 had been officially identified as SVHC.

In the United States, the list of restricted substances issued by the American clothing and Footwear Association (AAFA) (RSL) has been launched in March 21, 2011.

Although it is not a national standard, as a trade association covering more than 70% of the clothing and footwear brands and retailers in the United States, the list of restricted substances with self disciplined nature is undoubtedly a basic "green threshold" for its members' global purchasing and retail behavior.

For all kinds of ecological requirements and "green threshold" in the world, Lin Li thinks that

Environmental cost considerations

In 2007, Foshan Zhixing textile and garment company began using Colin's environmental dyes, not only improving the quality of dyeing, but also eliminating the washing process, which is both water saving and emission reduction.

But Yang Bin, deputy general manager of the company, also said that the dye was expensive and the cost of using it was increased by 2 yuan.

Under the situation of increasing production costs, many enterprises are unable to bear it.

But how should we consider the cost of environmental protection?

Yang Bin introduced one thing that enterprises encountered: as a result of the use of some foam finishing agent, the company's products were found to contain APEO. In order to solve this problem, the company spent more than ten million yuan.

This prompted the company to choose environmentally-friendly dyes and auxiliaries. The company's products also play an important role in environmental protection. The theme of green is not only improving the added value of products, but also getting a stable customer base.

Of course, the realization of green production is not just about using environmentally-friendly dyes and auxiliaries.

Lin Yaokun, deputy general manager of Guangdong Dongguan textile spinning and weaving company, said that the implementation of green cleaner production should be considered in all aspects of the whole production system, starting with product design, involving the configuration and selection of production equipment, fiber, yarn and so on.

As a leading enterprise in the industry, the black peony group effectively grasps the new opportunity for relocation and pformation into the park, and grasps the great opportunities for the construction of the new park, and promotes the pformation and upgrading of enterprises.

In the process of the construction of the park, the black peony group has made scientific planning and rational layout, making full use of the advantages of the industrial chain, and optimizing the allocation of all kinds of resources and energy through improving the cleaner production process, recycling of resources, the recycling of energy, the centralized disposal of waste, and the cooperative production between processes.

The black peony group has always chosen environmentally friendly recycled fiber materials such as bamboo fiber, hemp fiber, recycled fiber and so on in terms of product technology optimization and selection. It has developed a series of new ecological denim fabrics: developing organic cotton series denim with environmentally-friendly and pollution-free organic cotton; developing a series of environment-friendly cool and warm denim fabrics with new type of moisture absorption, sweat and warm fiber, which can reduce the energy consumption of 5%~6%, respond to the global requirements for low carbon and environmental protection; actively cooperate with new material suppliers, and develop a series of new functional fabrics that are suitable for seasons, antibacterial, UV resistant and environmental friendly.

The black peony group has developed water-saving dyeing technology by screening dyes and chemicals.

When designing and building a comprehensive office building, the black peony group abandoned the traditional air-conditioning technology of electric refrigeration, instead of the energy saving frontiers air conditioning technology, water storage air-conditioning, balancing the load of the electric network by using the energy saving air conditioning mode that uses the power grid's peak and valley electricity price difference, using cold water chiller to cool the house at night and cooling the main engine during the daytime, and greatly reducing the electricity consumption of the office buildings, and purifying the environment at the same time.

When installing new dyeing and pre shrinking production lines, the black Mudan Group invested nearly one million yuan to introduce steam condensate and waste heat recovery equipment, and carried out condensate recovery and treatment, resulting in considerable economic benefits; invested more than two thousand million yuan to build a water reuse process for advanced treatment of sewage, and realized reclaimed water reuse in processes and areas such as mercerized water washing, dyeing water washing, and life misuse. A coal-fired heat pfer oil boiler with serious pollution to the atmosphere was eliminated, and the natural gas combustion technology was directly applied to the pformation of the stereotype machine, which greatly reduced the emission of sulfur dioxide and nitrogen oxides.

LAN Yan group insists on independent innovation, willing to invest, and actively applies green energy saving technology, technology and materials by introducing advanced manufacturing technology, technology and equipment at home and abroad.

The new technology of non-woven dyeing of denim is independently developed by the company. Through the pformation of the traditional equipment, new dyeing and finishing equipment and ultraviolet modification treatment device have been realized, and the water-saving dyeing has been realized. The water consumption is 100%, and the energy saving is more than 10%.

The company creatively applies the high-efficiency spray wetting technology to the denim preshrinking finishing. After the implementation of the project, the water consumption is reduced by 80%, electricity saving is 20%, and steam consumption is saved by 70%.

The development of water-saving denim fabric adopts double-sided structure, reduces the dyeing ratio of warp yarn, saves 25% of dyeing and finishing materials, and reduces water consumption by 20%.

Henan Zhi Yongda textile company pays close attention to source control and promotes cleaner production.

The company invested 2 million 600 thousand yuan, using new technology to re design and pform the waste water treatment system, so that the quality of the wastewater reaches the first level standard, and the utilization rate of the wastewater is greatly improved.

The common feeling of these leading enterprises is that although they are used
