Socks manufacturing is not a high-tech industry, but it involves many detailed processes. Each section of the production must coordinate with each other to ensure quality requirements and time-controlling. The entire socks production process involves many steps, as shown in the below flow chart. It starts with preparation, design, raw materials, and machine coding. According to customer requirements and designing drawings, a company prepares yarns, such as veils, polyester, chemical fiber, etc. If necessary, dyed yarns are required. The quality and cost of socks are highly dependent on raw materials. The socks production company will select the suitable yarn for the customers' needs. These are followed by knitting socks that involve post-processing, sewing socks, embroidery, printing, and sewing. After the customized packaging and label packaging is done, socks are transported to the market.
