slitting machine
•
The slitting machine is used in processing fabrics in the open line in
the fishing section. The slitting machine consists of a blade and a
sensor attached to the blade which indicates the needle line during
slit opening the fabric for processing. In the slitting machine the
fabric is passed through the twister over the basket containing
exhaust fan for circular dropping of the fabric and the blade for
cutting the needle line of the fabric and then from the padder and
immersion roller through to the turning and delivery roller. Finally
the open width fabric is delivered.
Function of the Machine:
•
Slitting the fabric to turn tubular fabric to
open width fabric.
•
Softening the fabric by applying softeners.
•

Reducing the content water in the fabric.
•
Squeezing the fabric for proper chemical
penetration.
Main Parts of the Machine:
•
J-Box.
•
Twister.
•
Centering Roller.
•
Basket with Exhaust Fan.
•
Knife.
•
Padder/ Immersion roller.
•

Squeezing Machine
•
Squeezing machine is used for extracting water from dyed fabric by
squeezing through rollers having different pressure. Squeezer machine
designed to extract water from piece goods treated in rope form. They are
used as an intermediate devices such as washers or autonomous devices.
In the latter case they are usually full-width squeezers. The first padder
rollers gives proper squeeze to the fabric and extracts the water and the
second squeeze roller passes the fabric half the speed of the first squeeze
roller which causes the softener chemicals to properly pass into the fabric.
Function of the Machine:
•
To reduce fabric surface water content.
•
Squeezing the fabric for proper softening
chemical penetration.
•
Applying softening chemicals to the fabric.
Main Parts of the machine

Stenter Machine:
•
The Stenter machine consist of 7 drying chambers, padder rollers and
a weft straightening section which enables the machine to control
Spirality, Shrinkage, GSM during the fabric passage. During
processing first the fabric is passed through the padding section or
squeezer for properly squeezing the fabric and processing softening
treatment of the fabric through feed roller and guide roller. Then it
goes through the weft straightening section where by bowing roller
fabric spirality is controlled and then passed through chain rail for
shrinkage control.
Function of the Machine
•
To make the fabric dry.
•
For heat setting in case of Lycra, Viscose fabric.

•
To Control Fabric GSM.
•
To control Shrinkage.
•
To Control Spirality.
•
To control fabric Diameter.
•
To make the fabric soft by applying chemical.
•
Width control.

Dryer Machine
•
Dryer machine is used for removing the
residual water contained in the fabric after
squeezing by applying heat on the fabric. In
this machine the fabric is fed on the drying net
at low over feed speed and the humidity is
continuously measured. Drying is done by
applying heat through burner nozzles. During
drying the total heat passed through the
machine is extracted by the exhaust fan
Functions:
•
To dry the fabric with the help of blower and
burner.
•
To control the shrinkage of the fabric.

•
To prepare the fabric for next subsequent process.
•
To dry fabric without tension.
•
To remove residual water containing in the fabric.
Main Parts of the Machine:
•
Drying Net.
•
Heating Chamber:
•
Blower.
•
Burner.
•
Free Roller.
•
Centering Roller.
•
Scroll Roller.
•

Hot Air Circulation System:

•
In Stenter and Dryer machines air is recirculated which
passes from the exhaust stubs and air controller flaps. Then
the air is passed over the nozzles through which fabric is
passed and routes it over to the heat exchanger which lets
the air to be heated by the burner. The circulating air fan
allows the hot air to pass uniformly through the nozzles to
the fabric where the air controller flaps control the upper
and lower nozzle air and thus the fabric is heated. Finally the
used hot air is passed on to the exhaust air duct.
