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

Hot air stenter is one of the many types of the stenter and it is more obvious difference between the other stenters is the heating device ,it is through the hot air directly heating on the fabric , while some stenters make air as heating source ,such as air stenter .

In fact the stenter’s process itself is developed on basis of extrusion molding. The fabric after the treatment of hot air stenter is obbious differences between the products that no treament and from the appearance can be distighuished .

Tests have shown that the fabric is treatment by the hot air ,the strength has been significantly improved , can be achieved without processing products 3-5 times; and the fabric surface gloss will become better, the permeability of the fabric decreases with water and air and improve the value-in-use.

The fabric after treatment by hot air stenter , the thickness of the fiber has been reduced ,but the width is increased , so that reduce the production cost. In addition, its heating resistance will be improved ,it will not be easy to be deformation under the high temperature .

When the material is stretched in the stenter ,if the stretched is in one direction is called uniaxial tension,at that time the molecules in the material are aligned along the single axis; but if stretch is in different direction,that is double - axis tension . the molecules are aligned along the double-axis.

In contrast , the uniaxial stretching of the hot air stenter machine is widely used in synthetic fibers . But it’s easy to tear apart in the direction of the stretch. So now the machine is adopted double-axis tension to ensure the quality and performance of the fabric.
