The manufacturing method of pure polyester sewing thread 

1. Introduction 

In the field of chemical production raw materials, pure polyester sewing thread is an important product widely used in clothing, home textiles, industrial textiles and other fields. With the continuous development of technology, the manufacturing method of pure polyester sewing thread has also been continuously improved, improving production efficiency, reducing production costs, and improving product quality. This article will introduce the manufacturing method of pure polyester sewing thread, including raw material selection, processing equipment, manufacturing technology, and other aspects

2、 The main raw material for pure polyester sewing thread is polyester fiber. Polyester fiber has advantages such as high strength, good elasticity, wear resistance, and corrosion resistance, making it an ideal material for sewing threads. When selecting polyester fibers, factors such as linear density, strength, and elongation should be considered to ensure the quality and performance of the sewing thread

3、 The processing equipment for pure polyester sewing thread mainly includes spinning machines, twisting machines, winding machines, etc. These devices should have characteristics such as high precision, high efficiency, and high stability to ensure the quality and output of sewing thread

4、 The manufacturing process of pure polyester sewing thread mainly includes the following steps: 

1 Spinning: Processing polyester fibers into yarn through a spinning machine. In the spinning process, reasonable process parameters and control methods should be used to ensure that the linear density, strength, elongation and other indicators of the yarn meet the requirements

2. Twisting: Twisting the yarn through a twisting machine to improve the strength and elasticity of the sewing thread. During the twisting process, the appropriate twist and direction should be selected based on the yarn's linear density and purpose

3. Winding: The twisted sewing thread is wound into a certain shape by a winding machine, which is convenient for transportation and use. During the winding process, the winding tension and speed should be controlled to ensure the quality and shape of the wire coil

5、 Quality control: In the manufacturing process of pure polyester sewing thread, a comprehensive quality control system should be established to ensure that the product quality meets relevant standards and customer requirements. Quality control mainly includes raw material inspection, semi-finished product inspection, finished product inspection, and other links

6、 With the increasing emphasis on environmental protection and sustainable development, the manufacturing of pure polyester sewing thread should also consider environmental protection and sustainable development. In the production process, environmentally friendly processes and materials should be adopted to reduce the discharge of waste and pollutants, and improve the efficiency of resource utilization

7、 Conclusion: The manufacturing method of pure polyester sewing thread involves multiple aspects such as raw material selection, processing equipment, and manufacturing technology. In order to improve product quality and output, suitable raw materials, high-precision processing equipment, and scientific manufacturing processes should be selected. At the same time, quality control and environmental management should be strengthened to promote the sustainable development of pure polyester sewing thread manufacturing.
