Textile Wet Processing

An Introduction to textile Wet Processing

Fibers ,Yarns , threads ,Woven and knit textiles goods cannot be processed into apparel and other finished textile products until they have passed through several water-intensive wet processing stages. Wet processing enhances the appearance, durability, and serviceability of textiles by converting undyed and unfinished goods, known as gray or greige goods, into finished consumers’goods. Also collectively known as  dyeing and fmishing, wet processing has been broken down into four stages:

1.Fabric or yarn  preparation
To ensure that the textile has the right physical and chemical properties to enable it to be coloured or finished.
EXAMPLE:
Desizing, Singeing, Scouring, Bleaching etc.
2.Coloration or dyeing
To provide the textile with colour either for aesthetic reasons or for some functional purpose determined by the end-use of the product.
EXAMPLE:
Yarn Dyeing ,Fabric Dyeing
3.Printing
Textile printing is the process of applying colour to fabric in definite patterns or designs.
EXAMPLE
Roller printing, cylinder printing, or machine printing ,Stencil printing ,Screen-printing ,Digital textile printing 4.Finishing.
To provide the textile with the properties that the end-use demands and which have not already been provided by any earlier processes.
EXAMPLE:
Crease resistance, dimensional stability, stain resistant ,Water Repellency, Flame Repellency, Antisoiling finish etc.
These stages, involve treating gray goods with chemical baths and often require additional washing,rinsing, and drying steps. Note that some of these steps may be optional or repeated depending on the style-quality- type  of textile items being manufactured.
