How Effective Is The Energy Conservation And Environmental Protection Measures In The Textile Industry?

After several years of rapid growth, the textile industry has undergone significant changes in resource endowment conditions such as labor, land and market. Resources and environmental constraints have increased, labor costs and other factors have increased.

In addition, the new environmental law, known as "the most stringent" in history, has been formally implemented since January 1st this year, and the pressure on the textile industry in terms of energy conservation and environmental protection has been increasing.

According to the new regulations,

The direct emission of chemical oxygen demand (COD) needs to be controlled at 80 mg / liter. This is the improvement of the emission threshold of textile dyeing and finishing industry since the COD straight row standard was raised to 100 mg / litre in 2013.

The source of energy conservation and environmental protection is the optimization and innovation of spinning machine equipment and textile machinery technology, which is the premise to promote the overall upgrading of the entire textile industry chain.

With the gradual deepening of environmental protection concept, textile machinery has greatly improved energy saving and environmental protection.

Spinning equipment gradually develops towards large volume, short flow, automation and continuous production. Both single machine and complete sets of equipment are focused on improving quality, reducing cost and increasing efficiency.

Among them, the spinning collective doffer, thick and thin connection, thin connection, high speed energy saving spindle, air conditioning dust filtering equipment, new spinning form and motor system pformation have achieved remarkable results, and gradually become the hot spot of market pursuit.

As an important index to reflect the economic performance of weaving equipment, the importance of energy conservation is beyond doubt.

In order to reduce the consumption of compressed air needed for weft insertion, many looms have adopted modular design.

It not only improves the compactness of the structure and the convenience of operation, but also reduces the cost of equipment maintenance.

The development trend of chemical fiber machinery and equipment has been developing towards refinement and energy saving on the basis of large-scale, continuous and flexible development in the past few years.

Foreign textile machinery manufacturers are concerned about energy-saving, environmental protection and sustainable development of products.

As early as in 2004, Oricon chemical fiber introduced e-save energy saving signs for its energy saving systems, equipment and components, and established e-save energy conservation concept.

Over the years, e-save has interpreted the concept of comprehensive energy efficiency and emphasized the important role of orream chemical fiber in sustainable development.

In the domestic field, textile machinery enterprises have begun to attach importance to it in recent years and have achieved good results.

The fiber consumption of polyester staple fiber equipment of Heng Tian heavy industry Limited by Share Ltd has reached the domestic and even international advanced level: electricity consumption is 145 kwh, steam consumption is low to 750 kg, consumption of desalted water is less than 0.61 cubic meters, cooling water consumption is 51 cubic meters, refrigeration consumption is below 25 cubic meters, and industrial water consumption is 0.6 cubic meters.

In the current situation, energy conservation, emission reduction, clean production and reuse of water resources are very important topics.

Pre processing equipment for dyeing and printing will focus on water-saving, steam saving and emission reduction technologies and products. Hot alkali mercerizing, ultrasonic washing, foam treatment, chemical detection and distribution, wastewater reuse and waste heat recovery technologies and devices will be further developed and applied.

The finishing equipment adopts anhydrous processing technology, no plate making printing technology, low temperature plasma treatment technology, electrochemical technology, nano technology, biological enzyme technology, etc., so that the printing and dyeing finishing process is shorter, the production efficiency is higher, the product performance is better, more environmental protection and energy saving.

In terms of printing machinery, the digital printing machine has no sewage discharge, meets the requirements of environmental protection and energy conservation, continues to maintain high speed growth, and prints faster and further reduces the cost, and the market recognition is higher and higher.

Flat screen printing machine has been improving continuously in terms of increasing production speed and meeting heavy textile printing, and relieving the pressure of labor shortage and rising manpower cost through upgrading and upgrading some models.

Rotary screen printing machine continues to develop in a more precise, efficient, practical and convenient way.

In general, we must further develop new and highly automated printing and dyeing equipment, further study the technology and equipment to reduce energy consumption and reduce the amount of wastewater discharge; focus on the rapid desizing technology, ultrasonic washing technology and low bath ratio intermittent dyeing technology for woven fabrics; overcome the 50% difficulties of continuous knifing and water saving of knitted fabrics; and change the current situation of low occupation and low development of new wool dyeing and finishing equipment.

This year is

In the year of ending, reducing the cost, increasing efficiency and saving energy and environmental protection are the core contents of the 12th Five-Year plan for the textile industry. The importance of energy saving and environmental protection in China's textile machinery enterprises has been greatly improved, but it is relatively concentrated in the production process, and has not yet covered all the links in the whole production chain.

If the industry wants to have a great leap forward development, we must further innovate energy saving and environmental protection technology, develop energy saving and environmental protection models, and let the idea of energy conservation and environmental protection penetrate into every aspect of the development of the industry.
