The history of today's openers can be traced back to the 19th century, when people found that they could modernize production for the growing textile market. Openers have been around as the textile industry has developed, and they can greatly improve the production efficiency of the textile industry. Early openers were manually operated, requiring a worker to control the equipment and perform fiber unravelling operations. From the late 19th century to the early 20th century, with the improvement of machinery quality and the advent of national industrialization, the application of automation technology promoted the modernization of the entire textile industry. In the mid-20th century, due to the many unstable factors in manual and semi-automatic openers, a large number of production lines adopted network control technology to give the machines more automated working functions. Automated openers can complete the entire fiber fine unravelling process and ensure that the fiber particle size of various components is within a certain range, which reduces production costs and improves the quality of textiles. In the 21st century, the design of openers tends to be more humane and diversified. In addition to basic functions, openers have also received more attention: such as research on new materials for opening technology, improving operating efficiency, reducing energy consumption, etc. Therefore, in modern production lines, openers have become necessary fiber processing equipment and are widely used in the textile industry, pulp production and other related fields. At present, the development history of openers has exceeded 150 years. From the first generation of manual kiln design to modern automation technology, it is inseparable from the needs of the textile industry and the requirements of the market. In the future, openers will continue to play an increasingly important role, helping the manufacturing industry to improve quality, optimize production lines and reduce costs.
