Dyeing
 The normal process conducted for coloring cotton are yarn dyeing and piece dyeing. In piece dyeing process, dried fabric is continuously passed via a channel of hot-dye solution. After that the fabric is driven between rollers, which squeeze out color evenly and eliminates the glut liquid.
Yarn dyeing that is conducted prior to the fabric is knitted or woven. The process is used to roll out plaids, woven, gingham checks and other exclusive effects.
Other most usual process is package dyeing, in which yarn is slashed on perforated cylinders/packages and put on spindles in circled dyeing equipment.
Printing
 Roller-printing: Design on fabric conducted on roller-print machines, which functions at speeds from 50 to 100 yards per minute. Up to ten different colors can be printed in a single operation.
A usual printing machine holds a huge padded cylinders or drums that are bounded with copper rollers. Each copper roller has its own dyeing channel and blade which removes extra dye. As per the fabric design, the number of rollers differs due to the color in the design which is imprinted on a separate roller. The cloth picks up color from the imprinted area when it is driven further into the rollers and rotating drums. Then it is sent to a heated chamber which dries the dye instantly.
Automatic screen-printing - Slower than roller printing, it has the great benefit of making larger and complicated designs, complex shadings and a variety of handcrafted designs.
Flat bed screen-printing: In this process, the design is replicated on fine net screens, one for each color. The areas in the design, which are not gone through the dye, are covered with polish or some other anti-dye coating.
Rotary screen printing: The rotary screen printing machines produces up to 3,500 yards per hour. This system includes two process, roller and screen printing, using perforated cylinders rather than flat screens. Utilizing this process, 16 colors can be printed on a single fabric.
Finishing
 As the term states, finishing, is the last stage in fabric manufacturing. Several finishes can be put in to the practice to textiles.
Cotton fabrics are finished in many ways than any other fabrics, changing the feel, characteristics and looks. Sometimes, number of finishes is applied to a single fabric.
