[0002] Textile, from the narrow sense, is the process of processing fiber into yarn, and then processing yarn into fabric. However, from a broader perspective, textile encompasses the entire process from fiber raw materials to the final textile product. The original meaning of textile is derived from spinning and weaving, but modern textile is not just traditional hand spinning and weaving. It also includes non-woven fabric technology, modern three-dimensional weaving technology, modern electrostatic nanometer netting technology and other production of clothing, industrial, decorative textiles.

[0003] During the process of textile printing and dyeing, in order to ensure uniform dyeing, optimize physical properties, improve hand feeling and color fastness, and support functional processing, the textile is usually dried by a drying device.
