Because the quality of warping has a great influence on the production efficiency and product quality of the next process, especially weaving, the textile mills have devoted more energy to the research of their processes and equipment, resulting in the development of process technology. With great progress, the equipment has also been greatly improved. The major technological advances are manifested in the following aspects.
Increased line speed, wider range of transmission
In the past, warping machines used motors to drive gears or belts. The line speeds were not high. The silk weaving industry was generally 100 to 150 m/min, cotton was below 400 m/min, the speed range was extremely small, and the line speed fluctuates. Also larger. Now most of the warping machines use direct motor drive, frequency control, constant speed and constant tension winding, so that the warping and axial speed fluctuations are minimal, and the speed range is expanded, coupled with the improvement of the quality of raw materials and semi-products. As a result, the line speed of the warping machine has increased significantly. The line speed of warping can reach 1 000 m/min, and the speed range can be fine-tuned from 20 to 1 000 m/min, which provides good conditions for the correct implementation of the warping tension process.
