Stenter
  • Stenter is used for Heat setting the Elastane blended fabrics and also for the drying process.
  • Clips and pins are being used to hold the fabric inside the chambers where hot air is circulated by using nozzles in different conditions according to the process. (For Example – for heat setting the hot air temp would be around 200 deg C and for drying the hot air temp would be around 160 deg C).
  • Over feeding technology is provided to improve the physical characteristics of the fabric such as shrinkage,GSM,etc.,
  • Normal finishes as well as specialty finishes can be carried out with the padding attachment given in the machine.
  • A Weft Straightner can be included in the feeding zone to control the spirality of the fabric. 






Compacting

  • Compacting is an important process to improve the Dimensional Stability and the hand feel of the fabric.
  • The fabric will be passed through felt or rubber or metal shoe arrangements on a cylinder which should be heated by using steam and the fabric gets required dimensional stability when it passes through the compacting units.




Raising

  • Raising is a process to add value of the fabric.
  • Normally fleece / loop knit fabrics which are having loop structure in one side will be undertaken for the raising finish.
  • Raising effect will be occurred by using drum contains the piles and counter piles made by needles will rotates opposite direction of the fabric passing.
  • Sueding and peach finishing is nothing but the mild brushing of the fabric surface by using bristles made on nylon.

Tubular Padder
  • Water extraction by squeezing the fabric between two rollers leaving homogenous water content throughout the fabric
  • Stretching and squeezing of the fabric to remove all crease marks as well as to control the Lengthwise shrinkage which obtained in the dyeing process.
  • Applying softener to impart softness to value addition of the fabric




Slit open
  • Hydro extraction of the fabric
  • Opening the fabric from tubular form to open width form using the knife attachment
  • Conveyor belt facility provided to reduce the lengthwise stretch on the fabric which will improve the physical property of the fabric.




Relax Drier

  • Drier is used to remove the excess moisture content of the fabric.
  • Both Open width and Tubular form of fabric can be dried with relaxation which will be used to improve the Dimensional Stability of the fabric by the way of Over feeding technology.
  • Top and bottom nozzles are used to spread even heat energy on the both side of the fabric to get even drying of the fabric.
