Polyster Production Process

The technological options available mainly correspond to the capacity of production. Regardless of the technology used the production process involves the following process.
The production process of fabric making is divided into four main groups, each group constituting a number of operations and machinery. The main processes are spinning, weaving, dyeing and finishing.
  1. Spinning:
This process includes texture process, twisting process and sizing. In general it includes giving a special mechanical heat-setting treatment to the polyester filament/yarn, provide the weaving ability as well as to offer fabric the necessary strength and elasticity; align and prepare the weaver's beam in specified number of ends and length for weaving.
  1. Weaving process
This involves: Weaving preparation (that include reed drawing, dropper pinning and weft pirn winding) and weaving.
  1. Dyeing
This employs several piece dyeing methods under high pressure in either rope or open width. It also has hank-dyeing and cheese dyeing machines for yarn dyeing.
  1. Finishing Process
This is to finish the dyed fabrics in accordance with the specified width, length, density and handle etc. by heat setting and adding chemical agents.
The alternative technological option available is related to the production of soft and fluffy knitted products of exceptional quality by a technology of weft-knitted fabrics. The knitting features obtained in this way raise the level of the clothing's comfort of usage. This advantageous effect is the result of working-in a stream of untwisted fibers instead of the traditional yarn into the knitted fabric. Nonetheless, this option is not adopted by the envisaged plant since the manufacturing costs are higher than those for the classical technology.
