WHAT IS HTHP PACKAGE DYEING?
Dyeing method with High Temperature
130°C and High Pressure 4 kgs in the form
of package of any textile substrate in a
pressure vessel is called as HTHP Package
Dyeing.

What is a Cheese?
4
A cheese is a soft package wound at
certain density on dye springs or in
dye tubes, in order to allow the
permeability of liquor even at
adverse conditions.

Various substrates that can be dyed in HTHP ?
 Cotton
 Viscose
 Silk
 Wool
 Polyester
 Nylon
 Linen
 Acrylic
 Various Blends

What is Density ?
Mass
Density = ---------- = gpl
Volume
Volume = π / 4 ( D2 – d2 ) X H
Where,
 – 22/7
D – Outer Diameter
d – Inner Diameter
H – Traverse of the Cheese

WHAT IS FULLY FLOODED SYSTEM?
Fill water up to lid level and work through out
the processing cycle /
MLR is very high 1:8
Used for VAT
Needs expansion tank and back cooler
Conventional system
YMI
13

What is Air pad system?
Fill water up to cheese level and balance
portion with air
MLR is 1:4-1:8
Commonly used for reactive

What is SLR system?
Short liquor system
MLR is 1:2 -1:3
Mainly used for polyester dyeing
One way circulation is only possible –in to
