Is polyester hot melt yarn environmentally friendly?
As a new type of functional fiber, polyester hot melt yarn has been widely used in the textile industry in recent years. However, with the continuous improvement of environmental awareness, people have begun to pay attention to the impact of polyester hot melt yarn on the environment. This article will discuss in detail the environmental friendliness of polyester hot melt yarn from the aspects of production process, use process and waste treatment.
1. Production process of polyester hot melt yarn
The production process of polyester hot melt yarn mainly includes raw material selection, spinning, heat treatment and other links. In terms of raw material selection, polyester hot melt yarn usually uses 100% polyester as raw material, and the waste generated by these raw materials during the production process can be recycled and reused, thereby reducing the impact on the environment. For example, the polyester hot melt yarn production project of Suqian Dian Ge New Materials Co., Ltd. uses polyester waste yarn and polyester scraps as initial raw materials, and uses physical melting technology to make waste polyester materials into new fibers, which is in line with national and local environmental protection policies.
During the spinning process, the production of polyester hot melt yarn uses automated and semi-automated equipment to improve production efficiency, reduce energy consumption and waste generation. In addition, the wastewater, waste gas and solid waste generated during the production process are strictly treated and recycled to ensure that the impact on the environment is minimized. For example, after the production wastewater is pre-treated by “oil separation + flotation + hydrolysis acidification + contact oxidation + precipitation”, it meets the reuse standard and is reused for waste yarn cleaning water, vacuum water ring pump circulation replenishment water and greening water, and is not discharged.
2. The use process of polyester hot melt yarn
Polyester hot melt yarn has many advantages during use, which not only improves its application value in the textile industry, but also reduces the impact on the environment. First of all, polyester hot melt yarn has excellent bonding properties, can quickly melt and bond to other materials at high temperatures, and form a stable bond after cooling. This feature allows polyester hot melt yarn to replace traditional chemical adhesives in the production process and reduce the emission of volatile organic compounds (VOCs).
Secondly, polyester hot melt wire has high strength and wear resistance, and can withstand greater external pressure and friction, thereby extending the service life of the product and reducing resource waste. In addition, polyester hot melt wire also has good washability and anti-static properties, making the product less likely to fall off or deform during use, further improving its environmental performance.
3. Disposal of polyester hot melt wire
The disposal of polyester hot melt wire is an important part of evaluating its environmental friendliness. As a synthetic fiber, the waste of polyester hot melt wire can be recycled and reused to reduce the impact on the environment. For example, the polyester waste generated during the production process can be directly reused in production, reducing the discharge of waste.
In addition, the waste of polyester hot melt wire can also be treated by physical or chemical methods and converted into other useful products. For example, polyester waste can be made into recycled polyester fiber through processes such as crushing, hot melting, and pelletizing, which is used to produce various textiles. This recycling method not only reduces the pollution of waste to the environment, but also saves resources, which is in line with the concept of sustainable development.
4. Environmental impact assessment of polyester hot melt yarn
According to the environmental impact report of Suqian Dian Ge New Materials Co., Ltd., the production process of polyester hot melt yarn complies with national and local environmental protection policies and has a high level of clean production. The report points out that the clean production level of the project is Level II (advanced level of domestic clean production), and the pollutants generated during the production process are strictly treated and recycled, with less impact on the environment.
In addition, the production process of polyester hot melt yarn also adopts advanced processes and equipment, which has the advantages of high winding speed, environmental protection, simple equipment and short process flow. These characteristics not only improve production efficiency, but also reduce energy consumption and waste generation, further reducing the impact on the environment.
5. Conclusion
In summary, polyester hot melt yarn shows high environmental friendliness in production, use and waste treatment. Its production process uses environmentally friendly raw materials and advanced processes to reduce the emission of waste and pollutants; it has excellent performance during use, replaces traditional chemical adhesives, and reduces VOCs emissions; in terms of waste treatment, the waste of polyester hot melt yarn can be recycled and reused, which is in line with the concept of sustainable development.
Therefore, it can be considered that polyester hot melt yarn is an environmentally friendly material with broad application prospects. In the future, with the continuous advancement of technology and the improvement of environmental awareness, the production and application of polyester hot melt yarn will pay more attention to environmental protection and sustainable development, and make greater contributions to the green development of the textile industry.
