Hot Air Stenter Machine is a kind of equipment in textile printing and dyeing factory. The machine is characterized by stretching the fabric by heating and stretching both sides, with uniform latitude and width.

Natural fiber fabrics, such as cotton yarn, silk, wool, etc., because they have a certain degree of wet heat plasticity, in the printing and dyeing process, after the scouring, rinsing, dyeing, washing and other wet heat processing, the entire fabric is stretched. The warp and weft directions are shortened, and the cloth surface is not flat.

Through the warming of theHot Air Stenter Machine and the transverse drafting effect, the weft direction can be widened uniformly, the cloth surface is flat and beautiful, and the deformation of the fabric during the cutting and sewing process is reduced. The structure types of Hot Air Stenter Machine are as follows:

There are many types of Hot Air Stenter Machine, but the basic structure is only the following combination:

1.Guiding device:

It is used to smoothly guide the fabric into the tenter, which usually consists of multiple guide rollers, a suction device and a stand with rollers.

2.Drafting device:

There are two types of cloth and needle plate. Generally, cotton and wool fabrics are needle-board-type, while silk cloth types are used to fix the cloth surface, and it is convenient to apply tension on both sides to stretch the cloth surface.

3.Heating equipment:

There are two types of open and oven. Generally, cotton is used in the closed oven type, while silk is used in the open type, which is heated by steam and sprayed.

4.Ironing equipment:

After pulling the fabric with a needle plate or fabric, rough edges of the fabric appear. After ironing with steam in the middle, the flange will be removed and brought to a higher temperature. It can also stabilize the size of the width of the door that is rolled out, while making the ironing cloth smoother and brighter.

5.Lowering device:

The tent cloth passes through a series of guide rollers, and is then rolled into a roll, or enters a turning car through an S-shaped swing cloth and enters the next process.
