Standardization of textile machinery

The high repetition rate of identical parts across all machines is another characteristic of textile machinery. Take a spinning frame as an example: each machine has 400 spindles, spinning 400 yarns simultaneously, requiring 400 identical rings, spindles, etc. The number of needles used in knitting machines is even greater. A high-speed warp knitting machine with a working width of 6.6 meters requires 7280 grooved needles per machine. Machinery manufacturers producing these parts need to design corresponding tools, fixtures, molds, and even dedicated multi-station automatic machine tools or production lines based on the batch size of the parts to ensure high efficiency, high quality, and low cost in production.

 

The complexity of textile machinery parts is also reflected in their variety. Because different materials are processed, different types of parts need to be designed and manufactured according to different raw materials such as cotton, linen, wool, silk, and synthetic fibers. For example, wool spinning spindles need to be larger than cotton spinning spindles, but their structures are similar. Furthermore, due to the variety of fabric widths, there must be machine models with completely identical structural principles but different working widths. If the aforementioned parts and machine parameters are allowed to develop arbitrarily, it will adversely affect the product design efficiency, production management, and production costs of textile machinery factories. Furthermore, it will increase the workload of equipment management, spare parts inventory, maintenance, and replacement in textile factories, and may even cause chaos in factory management. The purpose of standardization is to use the simplest possible set of key technical parameters with appropriate numerical spacing as the design basis for a group of machines with different capacities, while meeting the principle of meeting different process requirements. For example, spinning frames are designed according to spindle pitch, looms and dyeing machines according to working amplitude, and knitting machines according to cylinder diameter, each forming a series of designs.
