Garment dyeing is the process of dyeing fully fashioned garments (such as pants, pullovers, t- shirts, jeans, sweaters, dresses, bathrobes, casual jackets, shirts, skirts, hosieries) subsequent to manufacturing, as opposed to the conventional method of manufacturing garments from pre- dyed fabrics.

Most garments are made of cotton knit goods and/or cotton woven fabrics.
Although several other fabrics can be found in the whole or in part such as wool, nylon, silk, acrylic, polyester and others. Garment Dyeing machines work on the principle of “movement of textile material and a stationary liquor”.The rotary drum dyeing machine consists of rotating perforated cylindrical drum , which rotates slowly inside a vessel of slightly bigger in size.

The internal drum can be divided into compartments to ensure rotation of goods with the drum rotation, and the outer vessel holds the required quantity of dye liquor.
