Polyester is often defined as long-chain polymers that are chemically composed of at least 85% by weight of an ester and a dihydric alcohol and a terephthalic acid. In simpler words, it means the linking of numerous esters within the fibers.
Basically, the reaction of alcohol with carboxylic acid leads to the formation of esters. Moreover, this kind of fabric may refer to several polymers, all of which the backbones are created by esterification condensation of both polyfunctional alcohols and acids.
Classification between Saturated and Unsaturated Polyesters
First and foremost, saturated polyesters refer to the type in which the polyester backbones are saturated. As a result, they’re not as reactive as any unsaturated polyesters. This is due to having low molecular weight liquids that are used as plasticizers and/or as reactants in developing urethane polymers. Most of the time, glycol and acid or anhydrides are used as reactants for saturated polyesters.

Unsaturated polyesters, on the other hand, are the type of polyesters in which the backbone consists of alkyl thermosetting resins characterized by vinyl unsaturation; and are mostly used in reinforced plastics. Needless to say, these are the most widely used and economical family of resins.
What are the Different Characteristics of Polyester Fabric?
- It is extremely strong in nature.
- It is quite durable, thus resistant to every chemical there is.
- It can easily be stretched and shrunk, but are wrinkle, mildew and abrasion resistant.
- It is hydrophobic in one way or another and quick drying. It can be used for insulation by manufacturing hollow fibers.
- It can retain its shape, so it is really good for making outdoor clothing especially for harsh climates.
- It can easily be washed and dried.
What is Polyester Fabric For?
History states that the earliest and most popular usage of polyester was to create polyester suits, which are the rage in the 70s. This kind of clothe was very popular at the time. And because of its strength as well as tenacity, polyester was also used as a material in making ropes. In fact, the PET bottles that you can see today are made of polyester.

How to Care of Polyester Fabrics
Taking care of polyester clothing is both easy and time efficient.
- It can be machine washed and dried, and you can add some fabric softeners to help you during the process. Lastly, dry the fabric at low temperatures so as to obtain maximum usage from the clothing.
- Although polyester does not really require much ironing, if you necessary, iron warm it.
- You can always dry-cleaned Polyester with no hassles.
Being able to learn a thing or two about polyester (and how popular it has become), you can only image how illustrious its history is. With the revival and success of polyester fabrics, it is without doubt something that is here to stay for the years to come.
