2. Dyeing is the process of adding color to textile products like fibers, yarns,
and fabrics. Dyeing is normally done in a special solution containing dyes
and particular chemical material.
TEXTILE DYEING
TEXTILE 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.
Fabric dyeing machine. Yarn dyeing machine. Knit dyeing machine. Woven dyeing
machine.TYPES
3. Fabric dyeing machine
1. Beam dyeing machine :
Features:
• Effectively used to dye yarn or fabric.
• Able to adjust water level in accordance to fabric
volume.
• Even dyeing and superior dyeing quality.
• Optimized circulation system along with high
performance pumps.
4. 1. Hank dyeing machine
Features:
• mostly used for dyeing of patterned wool carpets.
• Temperature control is done by electromechanical or
programmable logic controllers.
• Machine capacities can range from 10 kg sample machines to1
ton machines.
• Yarn loads up to 4000 kg can be dyed by coupling together of
machines.
YARN DYEING MACHINE
5. Knit dyeing machine
1. Winch dyeing
machine:
Features:
• construction and operation of winch are very simple.
• The winch dyeing machines are suitable for types of wet
processing operations from desizing to softening.
• The tension exerted on winch is less than jigger dyeing machine.
• The machine operates at a maximum temperature of 95-98°C.
Woven dyeing
machine1. Jigger dyeing
machine:
Features:
• The cloth can be dyed in open width form of full
width form.
• Chemical and heat loses are less when compared to
winch dyeing machine
• The material to liquor ratio is 1:3 (or) 1:4 which
saves considerable amount of chemical cost and steam
cost.
6. a) To improve fabric attractiveness.
By modification of fabric appearance(optical brightening),
By altering fabric handle (Softening, Stiffening) -Control of fabric dimension (Sanforising, Compacting)
b) To improve service ability
Protection of fabric (Flame proofing, Water proofing)
Improved performance (Water repellency, Raising)
Easy care properties (Resin finish, Crease recovery)
c) Shrinkage & gsm Control
d) Increase wash fastness
TEXTILE FINISHING
Textile finishing: The term finishing, in a board sense it covers all
the processes of making the fabric good looking, good hand
feeling, luster and of course for buyer requirement
Objects of finishing
7. SLITTER MACHINE
Features:
• Used to remove excess water after pretreatment and dyeing.
• To slit the tube fabric by the knife for opening of the fabric and ready for stentering.
• Delivered fabric in crease free state.
• Before squeezing balloon is formed with the help of compressed air passing by a
nozzle or air sprayer.
• It can control the diameter of fabric and GSM and shrinkage by over feeding
mechanism.
•
Dewatering Machine
Features:
• One for squeezing and other for applying softener finished.
• Above 80% water can be removed
• Maximum 60 inch diameter can be extended.
• Single squeeze roller and single padder present.
• Softener tank present
8. HYDRO EXTRACTOR MACHINE
Features:
• No deformation of the packages.
• Excellent rewinding properties. Rewinding can even be eliminated in a lot of cases.
• Low residual moisture.
• Even humidity distribution through the package.
• Low energy consumption.
• Dyeing tubes last longer.
Textile Compactor Machine
Features:
• GSM control of the knitted fabric. For high GSM, overfeed is increased
and fabric width is decreased. For low GSM, overfeed is decreased and
fabric width is increased.
Control shrinkage
Twisting control
Increase smoothness of fabric
Heat setting is done of fabric etc.
9. STENTER MACHINE
• Heat setting is done by the stenter for lycra fabric,
synthetic and blended fabric.
• Width of the fabric is controlled by the stenter.
• Finishing chemical apply on fabric by the stenter.
• Loop of the knit fabric is controlled.
• Moisture of the fabric is controlled by the stenter.
• Spirility controlled by the stenter.
• GSM of the fabric is controlled by stenter
• Fabric is dried by the stentering process.
• Shrinkage property of the fabric is controlled.
• Curing treatment for resin, water repellent fabric is
done by the stenter.
