Polyester synthetic fiber are one of the most popular types of synthetic fiber in the world due to their versatility, resistance and low cost. Fiber are used in many industries, from clothing and home textiles to industrial and automotive applications. The production of polyester synthetic fiber is a complex but attractive process that requires special machinery. In this article, we will introduce the machines and processes required to produce synthetic polyester fiber. The raw materials needed in the production of synthetic polyester fiber may be recycled materials called Flake or first-hand petrochemical materials. Petrochemical raw materials are produced in the form of PET granules by the polymerization process in reactors of the same name with the combination of polyethylene terephthalate (PET) and monoethylene glycol (MEG) at a certain temperature and pressure until the final product is TG granules with physical and chemical characteristics Suitable for the textile industry

Extrusion lines

The first step in the production of synthetic polyester fiber is taken in extrusion lines; The raw materials (filled with granules) are placed in the preparation machine at a high temperature for several hours to remove moisture and prepare the material for extrusion. This is the pre-extrusion preparation stage. After passing through the extrusion, the melted materials are directed out through the spinners. Spinnerets are plates consisting of small holes, the number and order of which determines the thickness of the fiber and the cross section of the fiber. Cooling rooms In the second stage of the polyester synthetic fiber production process, after extrusion, the molten fiber enter the quencher, where a temperature of about 10 degrees is provided through cold air or cold water pumps, causing rapid cooling of the extruded fiber. The rapid cooling process strengthens the polymer chains and stabilizes the molecular structure, giving the polyester fiber the desired physical properties. Accurate temperature and air flow control is essential at this stage to ensure uniform cooling and seamless quality. The fiber produced in the form of long filaments are stored in special tanks until they enter the stretching stage

Cooling rooms(quencher)

In the second stage of the process production of polyester synthetic fiber, after extrusion, the molten fiber enter the quencher, which has a temperature of about 10 degrees It is supplied through cold air or cold water pumps and causes rapid cooling of the extruded fiber. The rapid cooling process strengthens the polymer chains and stabilizes the molecular structure, giving the polyester fiber the desired physical properties. Accurate temperature and air flow control is essential at this stage to ensure uniform cooling and seamless quality. Fiber produced as long filaments are stored in special tanks until they enter the stretching stage

crimping machines

In many industries, especially in knitting industries, polyester fiber need to be flexible and voluminous. To achieve these properties, the fiber are drawn and then transferred to bending machines. These machines have a wave or rotary pattern and introduce these oscillations into the fiber as well, adding bends along their length. This bent structure increases the strength and malleability of the fiber and makes them more suitable for applications such as filling and blending with other fiber

Cutting and packing

When the desired properties of the yarns are obtained, the continuous polyester yarns are cut into pieces of specific lengths. Cutting length may vary from 50mm to over 100mm. These parts are packaged in different lengths and prepared for distribution to consumers in different industries

Quality control in the production of polyester synthetic fiber

During the production process of polyester fiber, strict quality control measures are taken to ensure that the fiber meet the required standards. Various test equipments are used to evaluate the physical and chemical properties of fiber. Fiber optic analyzers, tensile testing machines, and colorimeters are just a few examples of advanced equipment used to monitor and verify fiber properties. These tools help to detect any defects or inconsistencies to ensure that the quality of the final product is maintained

Environmental considerations of synthetic polyester fiber production

With increasing world awareness of the importance of environmental sustainability, units active in production of synthetic polyester fiber take environmentally friendly measures in the production process. are included Advanced machinery can be equipped with energy-efficient components and recycling systems that help reduce the total amount of carbon produced by industries. In addition, new innovations in catalysts and process optimization help improve more sustainable polymerization reactions and improve environmental performance in the industry.

Robotic processes in polyester synthetic fiber production processes

To increase the productivity and improve the production of synthetic polyester fiber , automation and robotics can be used in different stages of polyester fiber production. Automatic and intelligent systems can be used for handling raw materials and finished products in order to reduce manual work and improve worker safety conditions. The use of robotic lines is used in tasks that require precision, such as controlling the temperature of melting and quilting, fiber cutting, packaging and quality control.

Conclusion

The machinery associated with the production of polyester synthetic fiber is a symbol of decades of scientific research, engineering skill and technological advancements. From polymerization reactors to advanced automation and robotics, each step plays an essential role in converting raw materials into the polyester fiber we encounter in our daily lives. With the continuation of developments in this industry, emphasis on the use of effective methods in preserving the environment leads to more innovations that ensure that polyester fiber maintain their position as a basic material in many industries and applications. With the continuous research and development that is being carried out on the production of synthetic polyester fiber in research centers, universities and the private sector, the range of application of polyester fiber in various industries is wider and the position of this product as a main material in the modern world is more established
