Production technology of polypropylene high strength yarn and general strength yarn

Polypropylene high strength yarn and general strength yarn are made of polypropylene fiber, their production process usually has the following steps:

1. Raw material preparation: According to product requirements, select the appropriate polypropylene raw materials for ingredients. Additives such as colorants, antioxidants may be included in the raw material to increase the properties of the fiber or change its color.

2. Melt extrusion: feed the pre-mixed raw materials into the melting machine, and melt the raw materials through high temperature and high pressure conditions. The molten polypropylene is then extruded using an extruder to form a continuous molten fiber.

3. Spinning: The molten fiber is shot into the cooling air through the spinneret orifice to cool and solidify quickly. During the cooling process, the stretching mechanism can accelerate the stretching of the fiber and increase the strength of the silk.

4. Dipping and stretching: The primary silk obtained from spinning is impregnated and coated with materials that help to improve the properties of the fiber. Then, through different drafting processes, such as hot or cold drafting, the fibers are stretched to make their lines flatter and increase their strength.

5. Winding and packaging: the stretched polypropylene high strength wire or general strength wire is wound into the appropriate specification and form through the winding equipment, and then packaged and marked for storage, transportation and sales.

It should be noted that the production process of polypropylene high strength yarn and general strength yarn may vary depending on the manufacturer and product specifications. The production process plays an important role in the performance and quality of the final product. Therefore, when purchasing or using, it is recommended to refer to the product manual and relevant technical documents, and choose reliable suppliers and manufacturers.

Polypropylene high-strength yarn characteristics: polypropylene high-strength yarn because of its anti-aging, small thermal shrinkage, high strength and high tensile strength and impact resistance, making it a very competitive fiber raw material in the field of industrial silk.
