5. Introduction Textile Dyeing:
Dyeing is a coloration process of textile which is invariable carried out in an aqueous medium.
In the other hand, dyeing can be define as a process by which a yarn, fabric, garments and any other materials that come to contact of dye by presence of auxiliaries that create the condition of dyeing environment
Dyeing machine:
The machine which is used to dyeing or coloring of materials like yarn, fabric, garments or any other materials is called dyeing machine.
Dyeing machines come in all shapes and sizes to accommodate the various forms and quantities of textile materials. It is impossible to provide exhaustive coverage of this field. Therefore, the most important types of machine, and their problems, will be at the forefront.

Feature of SWASTIK Singeing & De-sizing Machines
Special burners, two of which are provided for the machine. These burners have a particular combustion chamber and are provided with water-cooling arrangement. The cloth can be threaded so as to allow singeing of either one or both sides. It is essential to note that the gas consumption per meter of fabric is less as compared with a machine of conventional design.
Both burners are titled away simultaneously (by 45º) by electro-magnets.
High Singeing speeds, infinitely variable between 80 mts. To 150 mtrs/min.
Excellent and uniform singeing effect with economical gas consumption.
Burners turning away automatically when the machine stops.
Efficient dust extraction device
De-sizing compartment with 12 /16 mts. Contents can be provided with a suitable squeezing mangle.

Scouring & Bleaching Range:

11. Woven Dyeing Machinery
Feture of Scouring & Bleaching Range:
Building block structure, suit for different weight fabric and different processing.
High liquid supply system can increase pick-up of liquid quantity, it makes the fabric suck the chemicals equally and fully.
The upper guide rollers of combination steamer are adjusted by frequency conversion transmission. It reduces crinkles due to changes of tension and meets the requirement of high-density poplin.
The fabric is heated enough before folding to insure the chemicals penetrate evenly,
This structure makes the saturated steam easy to penetrate and keeps temperature and humidity of the fabric so that it ensures the consistency of the scouring & bleaching.
It is not easy to get crinkles

13. Woven Dyeing Machinery
Function of Jigger Dyeing Machine:
A Jig Dyeing machine, is an efficient dyeing technique. It is also known by the name of jigger. Jig Dyeing machine processes fabrics in open width to avoid creasing problems in fabric dyeing. The process works like this. The Jig Dyeing machine operates by transferring the fabric back and forth. This happens from roller to roller via the medium of a dyebath, that is located at the base of the machine. As soon as the second roller gets full, the direction of movement of fabric can be reversed. In Jig dyeing, the duration of the process is measured on the basis of the number of passages or ends of the fabric passing through the dye bath from roller to roller. The end in dyeing parlance is known as the passing of fabric through a dye liquor from one roller to the other one.

Pad Batch Dyeing machine:
Pad Batch Dyeing machine is one of the widely used technique for semi-continuous dyeing process. It is mainly used in the dyeing of cellulosic fibre like cotton or viscose (knit and woven fabric) with reactive dyes. The characteristics of this machine is simple, and flexible and a substantial reduction in capital investment for equipment.

Types of Pad-batch dyeing machine:
Pad-batch process (semi-continuous)
Pad-roll process (semi-continuous)
Pad-jig process (semi-continuous)
Pad-steam process (continuous)
Thermosol process (continuous)
Pad-dry process (continuous)

17. Woven Dyeing Machinery
Special Features of Pad Batch Dyeing Process:
Significant cost and waste reduction as compared to other conventional dyeing processes.
Excellent wet fastness properties.
A uniform dye quality is achieved with even color absorbency and color fastness.
As compared to rope dyeing, Pad batch dyeing produces much lower defect levels
In pad batch dyeing, qualities like high shade reliability and repeatability are common. This is because of high reactivity dyes with rapid fixation rate and stability.

18. Woven Dyeing Machinery
Mercerizing Machine
Function:
Open with mercerizing machine for all kind of cotton & cotton blended as well as PES fabrics.
It will improve the fabric luster, increase the flexibility of the fabric and reduce dyestuff consumption.
During mercerization fabric is treated with 15% NaOH under high tension and pressure.
