Stenter machine can be defined as a stente finishing process in which the open width form of the fabric is treated to set up the required width, weight, and fabric texture as per customer’s specification.

A machine or apparatus for stretching or stentering fabrics. The purpose of the Hot Air 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.

Functions of Stenter Machines:

Heat setting is done by the stenter for lycra fabric, synthetic and blended fabric.

Width of the fabric is controlled by the stenter.

Finishing chemical apply on fabric by the stenter.

Loop of the knit fabric is controlled.

Moisture of the fabric is controlled by the stenter.

Spirility controlled by the stenter.

GSM of the fabric is controlled by stenter.

Fabric is dried by the stentering process.

Shrinkage property of the fabric is controlled.

Curing treatment for resin, water repellent fabric is done by the stenter.

Working Procedure of Stenter Machine:

The fabric is collected from the batcher to the scray and then it is passed through the padders where the finishes are applied and some times shade variation is corrected.The fabric is entered into the mahlo (weft straigtner) the function of the mahlo is to set the bow and also weave of the fabric is griped by the clips and pins are also provided but the pins has a disadvantage that they pins make holes at the selvedge but the stretchning of the pins are greater than the clips.these clips and pins are joined to endless chain.there are 8 to 10 chambers provided on the machine each chamber contains a burner and filters are provided to separate dust from air.the circulating fans blow air from the base to the upper side and exhaust fans sucks all the hot air within the chambers. Attraction rollers ar provided to stretch the warp yarn.

After stentering we can increase the width of the fabric up to 1.5-2 inch.The speed of the machine is about 7-150 m/min.3 meters fabric can run in each chamber.temperature is adjusted that according to the fabric as for,

PC 210 c

Cotton 110-130 c

After dyeing 160-170c and after print 130-140c.
