In the drying process, the fabric is usually combined with the corresponding drying equipment. drying.

The traditional drying method of drying equipment is generally to pull the children's clothing fabric into the drying box, and by sending hot air into the drying box, use the heat convection method to dry the surface of the fabric through the air jet. The main structure including the guide roller Generally, it is a fixed type, and the fabric is conveyed from the fabric outlet according to the established traction path, and the drying is completed during the fabric conveying process. Although the existing drying equipment can accelerate the drying speed of the fabric to a certain extent, the external heat and mass transfer capacity of the fabric is still weak. After the moisture in the fabric is vaporized under the action of hot air, the steam generated will be on the surface of the fabric.
