What is Polyester? – How the Best Polyester Fabrics Manufactured?

The popular polyester fabric that is now climbing the ropes of the textile industry – used to be part of the contemporary economy in 1926 as Terylene. During the 1930s and 1940s – Britishers developed better forms of ethylene fabric that got interest of American innovators.
During World War ll, the military forces were in the dire need of high-quality fibers for parachutes and other war materials, thus synthetic fibers like polyester come into existence. From the beginning to till date, consumers are highly enthusiastic about the improved fiber profile of polyester as compared to natural fibers.
Polyester fabric is one of the widely produced and consumed fabric in the world – today, you won’t find a piece of apparel that doesn’t contain some levels of polyester fibers in it. The good quality polyester is a rare gem and produced by the best textile company in the world only.
Story of BoPET                                                                                            
The best polyester fabrics are fabricated from long-chain polymers. Presently, two types of polyester are vividly manufactured – polyethylene terephthalate (PET) and poly-1, 4-cyclohexylene-dimethylene (PCDT). BoPET or abbreviated as biaxially-oriented polyethylene terephthalate) is a polyester film that is further made from stretched polyethylene terephthalate.
BoPET is widely manufactured as it is highly applicable and can be used in multiple ways – this is the reason why the best textile company in Surat – SDSPL invests in BoPET also. BoPET films are high in demand by numerous textile manufacturers due to its unique physical properties – high tensile strength, chemical stability, transparency, strong reflector, void from gas and aroma properties and highly insulated with electronic components.
Chemical Structure of Polyester
There are multiple types of chemical reactions are used to make different types of polyester. However, the common polyester is made when a chemical reaction at high temperature in a vacuum tube is conducted. In the chemical process, by-products of petroleum family-like alcohol and carboxyl acid are added to form a compound named – monomer.
This entire process is called polymerization. In this process, a polymer material is created which is extruded while hot into the long fibers until they are stretched about 5 times more than the original length. This stretch forms an arrangement of strong molecules to form a strong fiber.
Manufacturing Process of Polyester Fibres and Threads
To convert polyester polymer into threads or fibers, a spinning process is used. The spinning process can be further divided into two parts – filament type and spun type. In the filament type process – long fibers are twisted together, however, in the spun type process – small pieces of fiber are amalgamated together to form something called Staple. These spinning processes also helps in blending polyester fibers with other fibers like cotton or wool to form a new garment.
What Happens When Polyester Met Heat
To understand the complete textile solution of polyester, you got to understand how polyester behaves under heat. The polyester material can be either thermoplastic or thermoset. However, most of them are thermoplastic – that means they change their original shape once they come in the contact of heat. It turns into a combustible component at high temperature, but it shrinks away from flames and self destroy upon high ignition. So, if you are using pure polyester fabric, then keep it away from the iron.
Where You Can Find Good Quality of Polyester
China, Korea, and India are major manufacturers of polyester, however, polyester manufacturer in Japan and Indonesia also present, and some polyester production still occurs in the United States. However, the promising polyester players are in Asia because finished polyester fabric garments are mainly manufactured here before exporting to the world market. However, if you are looking for the best textile company manufacturing high-quality polyester fabric locally, then SDSPL is your final destination.
