The process of manufacturing polyester is fascinating. It is an artificial man-made fiber. Polyesters are generally manufactured from petroleum from which the constituent acids and alcohols are derived.
There are three steps in the synthesizing of polyester.
Different Types Of Polyester
There are several processes that can be carried out on the base polyester fiber. These processes add dimension to the polyester fiber as required for various end uses.
Polyester is a bright fiber by nature. However, it can be made dull or semi-dull by adding a delusterant. By changing the shape of the spinneret also, the hand and the strength of the fiber can be changed. Most spinnerets are circular. However, square, oval and bean-shaped fibers are also produced sometimes. Hollow fibers can also be created.
Polyester fiber is generally drawn to about five times its original length. However, drawing it out further makes it thinner. This is how the latest microfibers are being manufactured. Dyeing can give desired colors of polyester fiber. Normal polyester fiber is long and smooth. Crimping it can give the fiber more bulk and texture and increase its insulation capabilities.
Once the polyester fiber is ready it is used to make filament and spun yarns. The yarns can be blended with other fibers to make various blended fabrics.
Polyester and cotton are a popular combination. Wool and rayon are also blended with polyester to make fabrics.
