This document discusses various machines used for yarn wet processing. It describes the different steps in wet processing as pretreatment, coloration, and finishing. It focuses on types of yarn dyeing machines like skein dyeing, package dyeing using vertical and horizontal kier machines, and beam dyeing. Specific machines are described in detail like vertical and horizontal package dyeing machines, hank dyeing machines, and beam dyeing machines. Their features, advantages, and working mechanisms are explained.

4. STEPS IN WET PROCESSING SYSTEM
There are 3 different steps in the wet processing system. They are :
• Pretreatment Steps
• Coloration Steps
• Finishing Steps.
1. Pretreatment Steps
• Singeing
• De sizing
• Scouring
• Bleaching
• Mercerizing
2. Coloration Steps:
Dyeing and Printing
3. Finishing Steps
Soft Finish.
• Hard Finish.
• Medium Hard Finish
• Wrinkle free finish.

18. HORIZONTAL DYEING MACHINE
Horizontal Package Yarn Dyeing
Machine is best suited for silk yarn,
nylon yarn, textured polyester yarn,
acrylic yarn and other narrow
fabrics. In addition, it is easy to
install and require no extra effort
and can be done at very low cost.
The ceiling has to be of only 3
meters high and can function as
independent with just a press of a
button.

19. FEATURES OF HORIZONTAL DYEING MACHINE
• Uniform dyeing
• Low running cost
• Reversible pump
• Injector pump
• Low ML Ratio 1:3
• Touch Screen HMI
• Fully automatic operation

20. ADVANTAGES OF HORIZONTAL DYEING MACHINE
• Highly durable
• Excellent performance
• Sturdy construction
• Smooth operation.

26. ABEPAUTOMATIC SPRAYHANK DYEING MACHINE
• ABEP is a new technical evolution which is extended to
the wide range of products that Loris Bellini manufactures
for special applications on delicate yarns in hank form:
• Cashmere,Alpaca,Mohair,Wool and Blended Yarns
• Natural Silk Yarns and Blends with Viscose and Wool
• Filament Viscose Yarns
• Mercerized Cotton Yarns
• Acrylic Knitting Yarns, very-high bulk type (VHB).

27. H.T.H.PHANK DYEING MACHINE

28. H.T.H.PHANK DYEING MACHINE
• The GMW-HDD model is specially designed for dyeing of
polyester yarn/pc at a working temperature of up to 125°C
The high pressure injector pump injects the dyes when
the cabinet is pressurized,
• The air pad operation acts as an insulation, hence there is
low heat dispersion, Thus saves energy and steam
• Liquor ratio varies from as low as 5 - 6 : 1 for Malay
Dory(polyester blend) 9 – 10 : 1 for mercerized cotton and
12 - 14 : 1 for Acrylics

29. BEAM DYEING
• Beam dyeing is the much larger
version of package dyeing.
• An entire warp beam is wound on
to a perforated cylinder, which is
then placed in the beam dyeing
machine, where the flow of the
dye bath alternate as in the
package dyeing.
• Beam dyeing is more economical
than skein or package dyeing

30. BEAM DYEING MACHINE

31. BEAM DYEING MACHINE FEATURES
• Machine for dyeing yarns.
• Yarn wound onto a special beam that has evenly
perforated holes along its barrel.
• The yarn have better dyeing results.
• The high performance pumps circulate the dye liquor in
efficient manner to achieve even dyeing results.
• Liquor ratio and temperature as per requirement.
• Operating temperature max. 140°C
