Another characteristic of textile machinery is the high repetition coefficient of the same part of each machine. Take the spinning frame as an example. Each spinning frame has 400 spindles, and spinning 400 yarns simultaneously requires 400 identical rings and spindles. As for knitting machines, the number of stitches is even larger. Each high-speed warp knitting machine with a working range of 6.6m requires 7280 slotted needles. Machinery factories that produce these parts need to design corresponding tools, fixtures, molds, and even dedicated multi-station automatic machine tools or dedicated assembly lines based on the batch size of the parts to ensure the efficient, high-quality, and low-cost production of these parts.
The complexity of textile machinery parts is also manifested in their types, as different processing objects require designing and manufacturing different types of parts based on different raw materials such as cotton, linen, wool, silk, and chemical fibers. For example, wool spindles are larger in size than cotton spindles, but have similar structures. For another example, due to the diversity of fabric widths, it is necessary to have the same structural principles but different working ranges. If the above-mentioned parts and machine parameters are allowed to develop arbitrarily, it will have a negative impact on the product design efficiency, production management, and production costs of textile machinery factories, increase the workload of equipment management, spare parts storage, maintenance, and replacement, and even cause confusion in factory management. The purpose of standardization is to use the main technical parameters that are as simplified as possible and have an appropriate numerical spacing distribution as the design basis for a group of machines with different capacities, while meeting different process requirements. For example, a series of designs are formed for spinning machines based on spindle pitch, weaving machines and printing and dyeing machines based on working range, and knitting machines based on needle cylinder diameter.
