Purpose and requirements of twisting

Purpose:

Twisting is a necessary means to make fiber strips into yarns. Before twisting, it is generally necessary 

to condense the loose fibers into fiber strips. After twisting, the outer layer of the fiber is squeezed to 

the inner layer to generate centripetal pressure, so that the whiskers obtain friction along the length 

of the fiber.

Requirements:

The yarn obtains the best strength, elongation, elasticity, flexibility, gloss and feel;

The structural morphology of the yarn is diversified;

Improve the twisting efficiency of the yarn.

Production process of polyester yarn factory:

1. Raw material preparation: First, it is necessary to prepare the main raw materials for producing 

polyester filaments, such as polyester chips, catalysts, stabilizers, etc. These raw materials need to 

undergo strict quality inspection to ensure that their purity and performance meet production requirements.

2. Melt extrusion: Heat the polyester chips above the melting point to melt them into a liquid state. 

Then, the molten polyester chips are extruded into filaments through an extruder. In this process,

 it is necessary to control parameters such as extrusion speed and temperature to ensure the quality 

of the polyester filament.

3. Cooling and solidification: The extruded polyester filament needs to undergo a cooling and solidification

 process to change it from liquid to solid. Air cooling or water cooling is usually used to quickly cool and 

solidify the polyester filament.

4. Stretching and shaping: The polyester filament after cooling and solidification needs to be stretched 

and shaped to improve its strength and dimensional stability. During the stretching and shaping process,

 it is necessary to control parameters such as stretching speed and temperature to ensure the performance 

of the polyester filament.

5. Winding and packaging: The polyester filament that has been stretched and shaped needs to be wound 

and packaged for easy transportation and storage. During the winding process, it is necessary to control 

parameters such as winding speed and tension to ensure the quality of the polyester filament.

6. Quality inspection: During the entire production process, polyester filaments need to undergo strict 

quality inspections, including appearance inspection, size measurement, performance testing, etc. Unqualified 

products need to be reworked or scrapped.

Quality control:

Polyester filament factories need to establish a complete quality management system, including raw material 

procurement, production process, finished product inspection and other links. Specific measures include:

1. Strict raw material procurement standards to ensure that the quality of raw materials meets production requirements.

2. Regularly maintain and calibrate production equipment to ensure stable equipment performance.

3. Real-time monitoring of the production process to ensure that all parameters are controlled within a reasonable range.

4. Strict quality inspection of finished products to ensure that the products meet customer requirements and national standards.

5. Trace and analyze unqualified products, find out the causes of the problems and take improvement measures.

6. Regularly train and assess employees to improve their operating skills and quality awareness.
