Cooling Cylinder
To get the even dyeing in the continuous process, the inlet fabric should be maintained
at even conditions of temperature and humidity. The important function of cooling
cylinders is to maintain the temperature of the infeed fabric throughout the length
and width. This will ensure that there is no variation in fabric conditions as well as
no change in dye bath temperature. The temperature of the trough should always be
below 25° C during application of dye to the fabric.
2.6.2 Padder
The padder consists of two swimming rollers which has two pipes for hydraulic pressure. This portion is always covered with rubber sleeve. During application, hydraulic
pressure portion always faces the nip. Only the rubber sleeve moves (Fig. 33). Four
rollers are used to give more contact time between fabric and liquor. Padder is the
most important part of semi continuous and continuous dyeing machines.
S-Roll Padder Features
• Two swimming rollers
• Hydraulic system is used at the centre of padder whereas pneumatic system is used
at the edges
• Hydraulic pressure portion always faces the nip.
• Only rubber sleeve will move (Figs. 34 and 35).
