Polypropylene Yarn Production

It takes place in several stages. First, polypropylene, which is in the granules, is mixed with dyes and other additives. For example, it may be calcium carbonate. He will need to make the fabric white. In addition, it provides the desired level of rigidity.

The prepared mixture is poured into an extruder. It is treated at a temperature of 260 ° C.

The next stage after grinding the raw material is drying. Removes all excess moisture. For these purposes, use industrial furnaces. Drying is carried out at a temperature of 80 ° C.

All work is carried out automatically. The process is monitored by the worker. He controls that all stages are completed in compliance with the technology.

The warmed and dried mixture is passed through special nozzles. As a result, a film of a given thickness is formed. Subsequently, it is cut into threads. They are pulled and wound onto coils.
