The High Efficiency Of Textile Machinery Is

This was achieved by adding other corresponding measures on top of high speed. For example, the successful development of the exhaust box and the self-leveling device for carding machines combined cotton cleaning and carding, thus eliminating the lap-forming process and the cotton cleaning lap-forming device, saving a significant amount of handling work and improving efficiency. In combed wool spinning, the use of a self-leveling device (see drafting self-leveling) reduced the number of spinning passes from 7-10 in the 1940s to 4-7, reducing machine setup, saving factory space, investment, and labor, and lowering costs. Gradually replacing heavy manual labor and reducing the number of operators with mechanized and automated devices is another measure to improve the efficiency of textile machinery. Modern spinning machines are equipped with automatic doffing and bobbin insertion devices, replacing the heavy manual doffing operation; automatic splicing devices replace manual continuous splicing.

 

Textile machinery, originally developed by simulating human movements, has now become highly automated machinery with artistry and sophistication. The development of microelectronics, microprocessors, and computers resulting from large-scale integrated circuits has begun to permeate both individual textile machines and complete sets of machinery. High-speed automatic winding machines are equipped with electronic yarn clearers, which can automatically detect yarn defects and thick/thin areas, automatically cut them off, and automatically knot them. They can also interface with a microprocessor to classify and statistically analyze yarn defects and thick/thin areas. Fabric inspection machines equipped with microprocessors can display statistics on defect categories, defect locations, length of each roll of fabric (excluding damaged fabric), and weight in a statistical table format on a display screen. After inspecting a batch of fabric, they can output a report showing the total number of rolls, the number of defects classified, and the amount of damaged fabric deducted. They can also print out the results or record them on magnetic tape for future inspection.
