Application of RESO planar infrared module in textile dyeing industry

1/23/2025

The textile industry is the biggest polluter, ranking only second to the oil industry, emitting 23 kg of carbon dioxide for every 1kg of cloth produced. According to the United Nations, the total carbon emissions of the textile industry account for 10% of global carbon emissions, which has exceeded the total emissions of international flights and shipping. By 2050, the garment and textile industry will consume more than 30% of the global carbon budget.

The whole textile industry includes a lot of drying processes, such as drying after fiber cleaning, pre-shrinking, and dyeing. According to statistics, 70% of the textile industry's carbon emissions and energy consumption come from the printing and dyeing process, and the energy cost accounts for 10-20% of the industry's total cost. Therefore, in the Two-carbon policy background, In December 2021, the China Printing and Dyeing Industry Association issued the "14th Five-Year" Development Guidance for the Printing and Dyeing Industry. The development goals of industry growth, technological innovation, structural adjustment, and green development have been clarified; among the above goals, green energy use, the promotion of efficient heating technology, and the improvement of energy efficiency have become the top priorities.

So far, textile printing and dyeing mainly uses hot air heating, heating air, and hot air as a heat transfer medium, heating or drying fibers or fabrics. This method exits a lot of heat loss and poor energy utilization. In the above process, RESO infrared technology to replace traditional heating can greatly reduce energy loss and significantly improve energy utilization to reduce emissions and costs.

1. Energy saving and efficiency improvement
Most textiles, made of synthetic or natural fibers, are organic polymer materials that can absorb medium and long infrared waves. By matching the medium-long wave infrared from the RESO planar infrared system textiles, heat can be transferred directly to the product, thereby improving energy efficiency. In addition, the medium and long wave infrared can speed up the drying time, shorten the production process, and improve product quality.

The RESO planar infrared module has started its applications in cloth drying and clothing printing (Figure 1); compared with the traditional heating method, it can save more than 40% of electricity, helping to reduce the overall production cost by 4-8%. (Form 1)

Remarks: one production line for 20 baking stations, if the working time is 20 hours per day, 300 days per year, and the electricity price is 0.225 USD /KWH, Energy saving range >40%.

The traditional lamp infrared often needs to reach 500-800℃ to have a significant infrared effect, which temp. It is much higher than the ignition point of fiber materials. In the production process, if the textile fabrics or drifting fibrils touch the lamp's surface, it can easily cause a fire. Compared with the traditional solution, the RESO graphene planar infrared system suits textile printing and dyeing heating solutions. The planar infrared module can effectively stimulate infrared at a temperature lower than 300 ° C, and the operating temperature can be as low as 200 ° C, which ensures production safety to the maximum extent (Figure 2). The RESO infrared module can realize the face-to-face heating process with textile fabrics by using flat infrared elements, and the heating method is gentler, eliminating the local high temperature that may ignite the fabric. Therefore, the RESO plane infrared module is the most suitable heating technology for textile drying.
