Full process and semi-process of printing and dyeing techniques of garment fabric
n the realm of textile printing and dyeing, there are two principal methods employed: half-process and full-process. The distinction between these two approaches primarily lies in the extent of pre-dyeing treatments applied to the fabric.
The half-process technique involves a partial sequence of treatments before or during the printing and dyeing phase. For instance, it may involve only preliminary treatments like boiling or bleaching before proceeding to dyeing. This approach often results in less uniform coloration, suboptimal color saturation, and a tendency for the dye to fade more readily over time.
the full-process method encompasses a comprehensive treatment of the fabric, including preparatory steps, dyeing, printing, and finishing operations. This thorough process ensures uniform dyeing, enhanced color saturation, and improves both the colorfastness and durability of the fabric. In general, the difference between half-process and full-process for woven fabrics is mainly the absence of processes like mercerization and singeing in the former.
Mercerization, on the other hand, is a chemical treatment applied after the weave, which enhances the smoothness and sheen of the fabric surface. This can imbue the textile with a softer feel and a more visually appealing appearance. Learn more about mercerization here. The advantages of mercerization include brighter fabric colors, increased smoothness, and better dimensional stability.
Singeing is a technique that employs high temperatures and chemicals to burn off the surface yarn fuzz from the cloth, resulting in a smoother texture. Here's informative link on the singeing process.
