Trang 4Squeezing 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.
Squeezing Machine
Trang 5De-Watering M/C
After dyeing process from the dyeing machine then the fabrics arc ready for dc-watering This is the process to remove the water from the fabric partially by squeezing This is the main function of the squeezing machine But here also control the some important factor of the fabric quality
Trang 6Schematic Diagram of Squeezing Machine
Trang 7• To remove the water from the fabric.
• To control the width of the fabric
• To control the length of the fabric.
• To control the spirality of the fabric
• To control the over feeding system.
• To increase the softness of the fabric.
• To remove the crease mark of the fabric
• To reduce fabric surface water content.
• Squeezing the fabric for proper softening chemical penetration
• Applying softening chemicals to the fabric
Basic function of the squeezing m/c:

Trang 13• Polyreference or Centering roller.
Trang 151. Used to remove excess water after pretreatment and dyeing
2. To slit the tube fabric by the knife for opening of the fabric and ready for stentering
3. Delivered fabric is crease free state
4. Before squeezing balloon is formed with the help of compressed air passing by a nozzle or air sprayer
5. It can control the diameter of fabric and GSM and shrinkage by over feeding mechanism
6. To impart soft finish to the fabric by using required softener
Function of the Machine:
Trang 161. Squeeze roller (to remove water)
2. Stretcher (to control width)
3. Over feeding wheels (to control GSM)
4. De-twisting device (To delivery the fabric roll in untwisted form)
5. Folding device (to delivery the fabric in folded form)
6. Squeezing roller
7. Padder for softener
Main parts of the machine:
Trang 18Controlling points or Control system:
Manpower Required:
Worker: 02
Trang 19Production:
Capacity: 10 tones/shiftActual production: 7 tones/shift
Trang 20Feed roller pressure:
Trang 21Fabric Type Pad pressure Speed Over Feed
Trang 221. Diameter setting must be accurate.
2. Excess padder pressure may cause fabric damage Padder pressure depends on fabric construction
3. Speed must be optimum
4. Higher the fabric speed leads less removal of water
5. Overfeed
Controlling points:
Trang 231) Workers does not record the pressure, in dia and out dia of different fabric in record book
2) Workers set the pressure of squeeze roller for different fabrics same But higher GSM fabric needs more pressure than lower GSM fabric So removal of excess water is not sufficient
Find out the limitations and faults of the machine and advise for removing these
