Under the guidance of the "Dual Carbon" goals, green production has become the core direction for the high-quality development of the chemical fiber industry. As a key product in the chemical fiber sector, the environmental protection and energy-saving transformation of polyester drawn textured yarn (PET DTY) production is being fully advanced. Through the introduction of new equipment and process optimization, the industry has achieved a dual reduction in production energy consumption and pollutant emissions, delivering remarkable results in green development.
Currently, the green transformation in the PET DTY production field focuses on three major initiatives: First, replacing traditional spinning heating equipment with new energy-saving heating devices, increasing thermal efficiency from 75% to 92% and reducing energy consumption per ton of product by 18%; second, establishing water recycling systems, where treated production cooling water achieves a reuse rate of over 95%, enabling a single factory to reduce fresh water consumption by approximately 2,000 tons per month; third, upgrading waste gas treatment equipment and adopting a dual process of "adsorption + catalytic combustion," which raises waste gas treatment efficiency to over 98%, with all emission indicators exceeding the current national standards.
Industry data shows that after the completion of green transformation, PET DTY manufacturers can save an average of about 150,000 yuan in energy costs per month while reducing environmental governance investment. Insiders generally agree that green development has become the core competitiveness of the PET DTY industry. In the future, the industry will continue to explore new environmental protection and energy-saving technologies, driving production towards a greener and more efficient direction.
