Polyester bed sheets are widely used all over the world and its market has grown up to billions of dollars. Polyester bed sheets are economical, durable, light weight, soft and long lasting. There are few disadvantages as well of polyester bed sheets but people prefer it due to it’s low price. Polyester is also used with other fabric materials like cotton to make bed sheets. Bed sheets made with 100% polyester are called microfiber. However the blend of nylon and polyester is also known as microfiber in market.

What is Polyester
Polyester is not a natural fiber, polyester is man made synthetic material. Polyester has very good shape characteristics which makes it durable and thus polyester bed sheets can be washed many times. Polyester fiber is dense but lightweight at the same time. Some high quality types of polyester bed sheets are smooth and very soft to touch. Polyester is the most produced, most used and simplest form of synthetic fiber.
Most common types of Polyester Fibers
Polyester is made synthetically with a chemical reaction of coal, petroleum, water and air. In the result of two more molecules combine together to form long chains called polymers. The composition of these chains vary and thus form different types of polyester fibers. Two main types of polyester fibers made are called Polyethylene Terephthalate (PET) and PCDT (Poly-1, 4-cyclohexylene-dimethylene). PET is most widely used type of polyester, however PCDT is used in more heavier applications because of it’s strength.
How Polyester is Made
Polyester is made with help of chemical reaction at high temperature. The petroleum by-product, acid and alcohol are reacted to producers polyester. The main component in production of polyester is the ethylene which is derived from petroleum products. Ethylene is the polymer in the chemical reaction. The Polyester molecules produced are strong and stable. This process is known as polymerization.
The molten polyester polymers are extruded from reaction chamber and are allowed to cool down. After cooling process is done they are broken into pieces and chips formed are melted again. Long polyester fibers are made by extruding it through spinning methods.
The most common polyester type PET or ethylene polyester is made using four different procedures. These procedures vary slightly from each other depending on which polyester form or type is required. These four polyester fibers are filament, staple, tow and fiberfill.
Polyester Filament are continuous long fibers. Filament form polyester is used to make soft fabrics.
Polyester staples resembles staples which are used to make cotton yarn. Polyester staples are spun into yarn like materials.
In Polyester Tow fiber, the fibers are loosely arranged to form soft fabric.
Fiberfill polyester form consist of continuous polyester fibers. Fiberfill polyester fiber is dense and is used in production of heavy products like pillows and stuffed animals.
Polyester bed sheets are made from this synthetic polyester fiber. Polyester bed sheets made are highly durable fabric and usually can survive years of washing and wear.
