Stenter setting machine equipment is usually used for polyester and other chemical fiber products. The main purpose is to use the setting effect of the stenter setting machine to improve the feel, slippage, color, width, strength and appearance of the textile. Especially for non-pure cotton products, it can also stabilize the size. In actual operation, it is mainly to immerse the fabric with chemical material in the trough first, and then send it to the oven of the tenter setting machine after being uniformly pressed by the rollers. When the cloth passes through the oven, it will be dried and shaped under the action of high-temperature hot air. The shaped cloth has a good feel and stable size. In the stenter setting unit, there are many different components, among which the hot air circulation wind box is an important part. It is generally equipped with hot air circulating windmills and heat exchangers for drying or shaping cloth. During operation, the width of the fabric can be adjusted by adjusting the width adjustment mechanism.
