The manufacturing method
of regenerated filament
1. Introduction

With the continuous advancement of science and technology, the use of renewable resources has become a hot topic in today's society. In the field of chemical production raw materials, the manufacturing method of recycled filament has attracted wide attention. Recycled filament not only has the advantages of environmental protection and sustainability, but also can improve the utilization rate of resources and reduce production costs. This article will introduce the manufacturing method, process flow, equipment selection, quality control and environmental protection and safety measures of recycled filament in detail.

1. raw material selection and processing

recycled filament manufacturing first need to choose the right raw materials. The commonly used raw materials include waste textiles, waste silk, and falling silk. These raw materials need to be cleaned, dried, and classified to ensure the quality and purity of the raw materials.

2. Melt extrusion

The processed raw materials are added to the melt extruder, and the raw materials are melted and formed into filaments by high temperature and high pressure. During the melt extrusion process, it is necessary to pay attention to control parameters such as temperature and pressure to ensure the quality and output of the wire.

3. Stretching and setting

The wire after melt extrusion needs to be stretched and set to improve its strength and toughness. During the drawing process, the drawing ratio and drawing speed should be controlled to ensure the uniformity and consistency of the yarn. The shaping treatment can make the structure and performance of the silk more stable.

4. Winding and packaging

After stretching and shaping, the wire needs to be wound and packaged for storage and transportation. During the winding process, attention should be paid to controlling the winding tension and speed to ensure the winding quality and efficiency of the wire.

3. process flow chart

recycled filament manufacturing process flow chart is as follows:

raw material selection and processing → melt extrusion → stretching and shaping → winding and packaging

4. equipment selection

In the recycled filament manufacturing process, the equipment needed includes melt extruder, stretching machine, setting machine, winding machine, etc. When selecting equipment, it is necessary to consider factors such as production scale, product quality and cost. At the same time, the maintenance and maintenance of the equipment is also very important to ensure the normal operation and service life of the equipment.

5. quality control

In order to ensure the quality of recycled filament, it is necessary to establish a perfect quality control system. Including quality control of raw materials, quality control in the production process, quality inspection of finished products, etc. Through regular quality inspection and data analysis, we can find and solve problems in time and continuously improve product quality.

6. environmental protection and safety measures The manufacturing process of

recycled filament needs to pay attention to environmental protection and safety measures. First of all, it is necessary to ensure that the waste in the production process is properly treated and recycled to reduce the impact on the environment. Secondly, it is necessary to strengthen equipment maintenance and operation specifications to prevent safety accidents. In addition, it is necessary to conduct regular environmental protection and safety training for employees to improve their environmental awareness and safety awareness.

7. conclusion The manufacturing method of

recycled filament has the advantages of environmental protection and sustainability, which can improve the utilization rate of resources and reduce the production cost. Through suitable raw material selection and processing, melt extrusion, stretching and shaping, winding and packaging and other process steps, can produce high-quality recycled filaments. In the actual production process, it is necessary to pay attention to the details of equipment selection, quality control, environmental protection and safety measures to ensure product quality and smooth production. With the growing concern about sustainable development and environmental protection, the manufacturing method of recycled filament will be more widely used and promoted in the future.
