5. 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.

9. 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.
11. • 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
• Roller width: 1800-3600mm
• Machine speed: 15-80m/min
• Drive: PLC, AC motor with inverter

13. 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.

14. Latest in Jig Dyeing Machines:
Features
Operates by electricity, and fully controlled by a
PLC
Cutting edge technology in the form of speed
measuring device on foot roll barrel. This helps in
maintaining uniform line speed along with a reliable
testing signal.
Comes with built in dye solution circulatory system
and charging system.
Use of latest technologies in the form of automatic:
Reverse
Way-change
Length Count
Temperature Control
15. 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.

16. 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. 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. 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.
20. Better shrinkage results thanks to the high tech drive system with load
cell control
Extremely constant shrinkage results thanks to automatic shrinkage
control (option)
Production output increased by 20 – 40 % due to an improved
geometrical design of the rubber belt unit
Extended life span of the rubber belt due to larger diameter of
compression and tensioning rollers and an optimized cooling system
Reproducible results as all machine parameters are automated with
recipe administration software. No manual settings (e. g. valves, handwheels)
required
Rubber belt resurfacing/grinding unit fully integrated into the machine
(no mounting of external unit necessary) – grinding process controlled via PLC to
avoid operation errors
Very solid and long lasting machine design with minimized vibrations to ensure a
smooth fabric run
All bearings are located outside the wet to avoid corrosion

Note:Note:
• Pre-drying by infrared or hot air gradually until the drying percentage 70%.
• Thermofix and washing off should be carried out immediately when the fabric is dried after
padding dyes.
• Pad-dry-thermofix can have reduced fastness properties, pre-trials are necessary.
