TexTile Processing:-
Textile processing
is one of the important technology related with textile manufacturing operations. This industry has a long history that begins with "Indigo dyeing" a natural color, derived from a plant.
Once the process of coloring textiles was considered as an art. According to ones creativity and imagination on those days numerous techniques were evolved in coloring different materials such as cotton, bamboo, jute, earthen-ware and even mortar walls. Slowly this technique was evolved in to a science and so many artificial coloring matters called 'dyestuffs' had started coming in to existence.
This evolution of coloring matters in to synthetic dyestuff and the application techniques on various textile materials are all put together is called 'Textile Processing'.
Textile processing is a general term that covers right from singeing(protruding fiber removal) to finishing and printing of fabric.
1) Singeing is the process of removing the pills and protruding fibers of the fabric coming from weaving. This operation may either be done at the beginning of the process or at the end of the finishing operation.
2) Desizing is the second operation after singeing. Desizing of fabric is essential to remove the sizing materials added during warping to strengthen the warp yarns. This size if present during subsequent processing will affect the quality of look and finish. There are many ways to remove the size from the fabric. A few methods are as below.
a) Acid Desizing - this is an old process of destroying the starch and other size materials
in th presence of acid at elevated temperatures.b) Oxidative desizing method - desizing with the help of an oxidizing agent such
as Hydrogen peroxide.c) Enzymatic desizing method - this is a bio degradation method that destroys starch
and other sizing materials in to soluble form that will be washed off during subsequent
washes. 3) Bleaching Process: Bleaching is a process to make the fabric or yarn look brighter
and whiter. This is achieved by oxidizing or reducing the coloring matters in to colorless
form.
Mostly widely used textile bleaching method is Hydrogen Peroxide bleaching. This is carried out in an alkaline bath at about 80 to 85°C at a pH of 11.
