Flow Chart of Textile Wet Processing for Knit Fabric

Textile Wet Processing: 

Textile wet processing is one of the important branches of textile engineering. Where this process is applied to the textile in form of liquid with involves some chemical action on the textile. In textile wet processing, it can be divided into three processes that are preparation process, coloration process, and finishing process. This process is done for woven and knit fabric. But this process varies from the buyer’s requirement. In this article, a flow chart of textile wet processing for knit fabric is given below.

The knitted fabrics undergo a series of different chemical processing treatments. Such as: scouring, bleaching, dyeing, hydo extractor or dewatering, stitching, stentering, compacting, softener padding, relax drying, final inspection. These processes is carried out to impart a particular property related to that process like scouring for absorbency, bleaching for whiteness, dyeing to impart color to the fabric. And finishing for improving the softness and handle of the fabric.

The properties of the knitted fabrics are influenced by various parameters. Like raw material, yarn structure, fabric structure, processing stages, and finishing. The process adopted affects the fabric properties and its overall performance.

During the finishing process, internal stresses stored during spinning, knitting is removed. The fabrics attain an almost fully relaxed state. By adopting different processes and finishing methods, different kinds of knitted fabric in a sense of aesthetic and utility properties can be produced from the same unfinished fabrics. The knits goods, in contrast to the woven cotton fabrics, are easily starched and their loops would get distorted under the stretching tension of the dyeing cylinders. Special drying machines have, therefore, been developed to dry knitwear with the minimum of tension.
