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.

As a manufacturer of hot air stenter machinery, LiCheng focus on this area for many years, Our hot air stenter machine has many advantage not only in the production, but on the effect of Flat Screen Printing Machine.

Structure and Function of Flat Screen Printer.

1, Cloth Feeding Device

A roll or a folded feed can be used as needed.

2, The Printing Part

It consists of an automatic guiding mechanism, automatic lifting frame mechanism, and automatic printing mechanism.

(1) Automatic guide mechanism: It consists of a printed guide belt, belt drive, and transmission control. The printed belt is a seamless looped rubber belt made of multi-layer canvas rubber. There are two ways to drive the belt: one is intermittently driven by the belt and the printing unit is intermittently distributed; the other is that the belt is intermittently driven in the printing areas and continuously driven in the non-printing area.

(2) Lifting screen frame mechanism

The screen frame is automatically lifted and lowered by a cam mechanism and an eccentric link mechanism. When the fabric and the belt are suspended, the screen frame of the stencil is automatically lowered, pressed against the surface of the cloth for squeegeeing, and when the squeegee is finished, it is lifted off the cloth surface to make the fabric and the belt run.

(3) Automatic printing mechanism

After the guide belt stops running, when the screen frame is lowered to the predetermined position and stops moving, the scraper or the squeegee roller presses the screen to perform squeegee so that the color paste passes through the mesh of the screen pattern portion smearing onto the fabric.

Composition: scraper or scraper roller, transmission and control part, slurry part.

3, The drying device

The hot air drying machine is used to loose drying.

Working process: the printed fabric leaves the printing guide belt and rests on the active running nylon wire loop conveyor belt. The conveyor mesh belt lifts the reverse side of the fabric into the drying machine discharged after being dried by multiple layers. The position of drying guide belt (the conveyor belt) is adjusted by the positive position device at the feeding of the drying room. The speed of the printed part and the drying part is determined by the linear speed regulator installed between the printing belt and the drying conveyor belt ( Generally, the infrared detector is adjusted according to the change of the loose position of the fabric.) Loosen more, the dryer speeds up, and vice versa.
