Production stages:
- Processing of raw materials of secondary type.
To create raw materials based on recycled materials, a grinder is used. The main element of the latter is a drum that grinds the material to the desired dimensions. The device is operated by one person. This employee undertakes to monitor the functioning of the equipment, load the material for processing, and also monitor how the bunker is filled with raw materials. bags can be ordered in bulk.
- Drying of raw materials.
During this stage, early drying takes place - this is done in order to prevent the formation of vapors inside the heating hopper of the extruder. The necessary actions are carried out in an industrial oven, heated to a temperature of 80 degrees Celsius, until all moisture is removed from the original raw materials.The above temperature creates conditions for the release of substances harmful to health, so you should resort to the use of an exhaust-type ventilation system.
- Mixing of raw materials, as well as fabrication of material for the purpose of fabric production.
The raw material is poured into the extruder, after which it is mixed inside the receiving hopper, where, if necessary, a dye is added. After that, the raw material is transferred to a heating-type tank, in which the temperature is constantly maintained, which is optimal for melting. Upon completion of the melting process, the hot mixture is fed through a slotted nozzle. A layer of a polypropylene-type film is formed, which cools down due to the action of air pressure.
- Cutting the film to form a thread.
With the help of a machine, the film is cut into threads of a certain width, after which it is wound on special coils. The latter are used in the weaving loom. When cutting, it is worth making sure that the threads have the same thickness. If necessary, you can adjust the operating mode of machine knives. Only a qualified specialist is allowed to perform such work.
- Fabric manufacturing.
To create a fabric, you need to resort to using a circular loom. This unit forms a sleeve of the required dimensions from a thread that is wound on coils.
- Image printing.
At this stage, a flexographic type machine is used. For efficient operation of the unit, elastic dyes are used.
