What is Polyester Fabric?
Polyester fabric is the one of the world's most popular textiles. It is popularly used in the people's daily life and industrial applications. So, what is Polyester fabric? And how is Polyester made?
First, Polyester fabric is a synthetic fabric that's usually derived from petrolium. Chemically, Polyester is a Polymer primarily composed of compounds within the ester functional group. Most synthetic and and some plant-based polyester fibers are made from ethylene, which is a constituent of petroleum that can also be derived from other sources.
What is Polyester Fabric?
Avantages
- When Polyester blended with cotton, It improves the shrinkage, durability and wrinkling profile of this widely-produce natural fiber and reduces production costs.
- Highly resistant to environment conditions, which makes it ideal for long term use in outdoor applications.
Disavantages
- Most of forms of polyester are not biodegradable. Polyester production and use contribute to polluttion around the world.
- Polyester decreases the comfortability of apparel when blended with cotton or another natural fiber.
How to make Polyester Fabric?
Next, Including 5 steps to make Polyester, as below:
1. Creating a monomer
The process of creating polyester fiber begin with reacting ethylene glycol with dimethyl terephthalate at high heat. This reaction results in the monomer.
2. Creating a polyester
The monomer is then reacted with dimethyl terephthalate again to create a polymer.
3. Extruding
This moltern polyester polymer is extruded from reaction chamber in long strips, and these strips are allow to cool and dry, and then they are broken apart in to small pieces.
4. Spinning
The resulting chips are melted again to create a honey-like substance, which is extruded through a spinneret to create fibers.
5. Finishing
The resulting polyester filament may be cut or reacted with various chemicals to achieve the correct end result.
The production processes used to make polyester may vary depending on the type of polyester is made: Ethylense Polyester, PCDT Polyester, Plant-Based Polyester
