1. Spinning: the process of processing various textile fibers into yarns. Some yarns need special treatment before weaving, such as dyeing and double twisting.

2. Knitting: a fabric made of knitting needles and other knitting machines, which makes the yarns form loops and strings the loops at the same time. The knitting structure is a little more complicated, similar to knitting a sweater, and the loops are interlocking; Braided structure is the most primitive and simple tic-tac-toe structure.

3. Dyeing: it is a process of coloring fiber materials with dyes or pigments and making them have a certain fastness. Then, the cloth that has been shaped for the first time is put into a cylinder for processing. The cloth after being discharged from the cylinder is shaped for the second time, with the purpose of drying the cloth, controlling the width weight, leveling the cloth surface and waiting for printing.

4. Finishing: refers to improving the appearance and internal quality of the fabric through physical and chemical processing, improving the wearability of the fabric or giving it special functions.
