Sustainable China Functional Fabrics production process improvement: in-depth exploration towards green manufacturing

1. Closed production process: the cornerstone of building a circular economy
The closed production process is an important innovation in the production of Sustainable China Functional Fabrics. The core of this process is to form a closed-loop system for efficient resource utilization by optimizing the production process, reducing material loss and environmental pollution in the production process. Specifically, the closed production process covers the entire process from raw material input to product output, and ensures that each link can achieve maximum material utilization and minimize pollution emissions by precisely controlling production parameters.

In the process of fabric processing, traditional open production is often accompanied by a large amount of wastewater, waste gas and solid waste emissions, which not only puts pressure on the environment, but also increases the environmental governance costs of enterprises. The closed production process effectively solves these problems by introducing advanced wastewater treatment systems, waste gas purification devices and waste recycling and reuse technologies. Some companies use membrane bioreactor (MBR) technology to treat wastewater, which can not only efficiently remove organic matter and pollutants such as nitrogen and phosphorus, but also realize the recycling of wastewater, significantly reducing water resource consumption and wastewater emissions.

The closed production process also focuses on energy recovery and reuse in the production process. By installing a heat recovery device, the heat energy generated in the production process is converted into electrical energy or thermal energy for use in other links, achieving efficient recycling of energy. This process not only improves resource utilization efficiency, but also reduces the energy consumption and carbon emissions of enterprises, laying a solid foundation for building a circular economy system.

2. Recycling technology: a new path to resource conservation
Recycling technology is another highlight in China's sustainable functional fabric production. This technology aims to maximize resource utilization and minimize environmental impact by recycling and reusing waste and by-products in the production process. In the fabric production process, waste mainly includes wastewater, waste gas, waste residue, and scraps.

For wastewater, in addition to the wastewater treatment system in the closed production process mentioned above, some companies have also adopted higher-level wastewater reuse technologies, such as ultrafiltration and reverse osmosis, and directly used the treated wastewater for flushing, cooling and other links in the production process, achieving zero or low discharge of wastewater.

For waste gas, enterprises usually use treatment technologies such as adsorption, condensation, and combustion to remove harmful substances in the waste gas and then reuse it as fuel or raw material. Some enterprises use the heat energy in the waste gas to generate electricity or heat, which not only reduces environmental pollution but also saves energy.

For waste slag and scraps, enterprises convert them into new raw materials or semi-finished products through physical crushing, chemical dissolution and other methods for the production of other products. This recycling method not only reduces the emission of waste, but also reduces the cost of raw materials and improves the economic benefits of enterprises.

3. Green processing technology: eco-friendly practice
Green processing technology is another important link in the production of Sustainable China Functional Fabrics. This technology aims to reduce the emission of harmful substances in the production process and improve the environmental performance and eco-friendliness of products by using environmentally friendly dyes, auxiliaries and advanced processing equipment.

In the selection of dyes and auxiliaries, enterprises prefer to use low-toxic, low-pollution, and easily degradable environmentally friendly products. These products not only have less impact on the environment during the production process, but also maintain good stability and durability during the use of the product, reducing the generation of waste.

In terms of processing equipment, the company actively introduced advanced automated and intelligent production equipment, and improved production efficiency and product quality, and reduced energy consumption and waste emissions by precisely controlling production parameters and optimizing production processes. The application of waterless weaving technology, through the use of special weaving processes and auxiliaries, has achieved zero or low water use in the fabric production process, greatly reducing water resource consumption.
