Dyeing Industry Name: Rupa Knit Composite Ltd.

The purpose of the stenter machine is to bringing the length and width to pre-determine dimensions and also for heat setting and it is used for applying finishing chemicals and also shade variation is adjusted. The main function of the stenter is to stretch the fabric widthwise and to recover the uniform width.
Stenter machine consists of two endless auto-lubricated driven chains, typically 40 to 60 m in length carrying pins or clips to hold the fabric edges while passing through a number of hot-air chambers (3–5, each of about 3 m). Hot air is directed onto the fabric equally from above and below. A stenter has the provision for overfeeding the fabric to allow required shrinkage during heat setting of fabric while the width is increased to the precisely specified value by the chains. The use of clip stenter has declined because of the difficulty of applying overfeed. The stenter speed ranges from 10 m/min for heavyweight furnishing fabrics to 100 m/min for lightweight dress-goods.

The speed also depends on the processes carried out in stenter namely:
1. Drying,
2. Heat setting,
3. Weft straightening,
4. Curing after application of finishes.

The controllers fitted in a modern stenter may monitor and control the following parameters:
1. Chamber temperatures,
2. Moisture retention,
3. Stretch/shrinkage (over feed),
4. Fabric width,
5. Fabric weight,
6. Padder pressures,
7. Exhaust humidity.

The main functions of a Stenter Machine are here,

1. Stenter Machine controls the deformation of the width of the fabric.
2. A Stenter Machine saves the fabric from shrinkage.
3. Stenter Machine does some kind of heat setting for some specific goods like synthetic fabric, lycra fabric, and blended fabric.
4. A Stenter Machine has to be able to make a Proper finishing of chemical treatment it performed itself.
5. The machine also controls the knit of the fabric.
6. The moisture remains in the proper ratio in a Stenter Machine.
7. Stenter Machine controls the spirituality too.
8. GSM remains in the desired ratio in this machine operation.
9. Stenter Machine can dry the fabric as well.
10. Stenter Machine performs some curing treatment for resin and water repellent in fabric.
