General specifications of polyester
Synthetic Filament’s production and consumption has been commercialized since 1940 and nowadays has a significant share of fiber consumption. These fibers have differences with natural fibers, but due to the possibility of mixing two or more polymers, there is an economical way to acquire new fibers with desirable properties.
Synthetic fiber extrusion method that is often concentrated on output with pressure through the tiny holes called spinneret which are produced continuous polymer filaments. Among the important methods for the production of synthetic fibers, melt spinning, wet spinning, Gel spinning also known as dry-wet spinning.
The melt spinning method (which is used in Savis Textile Co.) is a technique used for rapid cooling of liquids. A wheel is cooled internally, usually by water or liquid nitrogen, and rotated. A thin stream of liquid is then dripped onto the wheel and cooled, causing rapid solidification.
Characteristics of Polyester
- Polyester fabrics and fibers are extremely strong.
- Polyester is very durable: resistant to most chemicals, stretching and shrinking, wrinkle resistant, mildew and abrasion resistant.
- Polyester is hydrophobic in nature and quick drying. It can be used for insulation by manufacturing hollow fibers.
- Polyester retains its shape and hence is good for making outdoor clothing for harsh climates.
- It is easily washed and dried.
