The air jet weaving machine is a shuttleless loom that uses compressed air as the power to quickly draw the weft yarn through the shed to complete the weft insertion. Compared to traditional shuttle looms, air jet weaving machines have advantages such as high weaving speed, low noise, low energy consumption, and a high degree of automation. They are widely used in the fields of high-density fabrics, wide-width fabrics, industrial fabrics, and more.
1949: The first air jet weaving machine was manufactured in Czechoslovakia, but due to uncontrollable airflow diffusion, the weaving width was only 45 cm.
1956: The invention of a combined pipeline plate effectively limited airflow diffusion, achieving a breakthrough.
1963: The Netherlands developed auxiliary nozzle weft insertion technology, significantly increasing loom width and speed.
1970s: The advent of special-shaped reeds improved the range of weavable products and enhanced fabric quality.
In recent years: Jet looms have been developing towards energy-saving, intelligent, networked, high-speed, and low-vibration directions, further improving weaving efficiency and quality.
Air jet weaving machines use compressed air as power. Through the combined action of the main nozzle, auxiliary nozzles, and special-shaped reeds, the weft yarn is quickly drawn through the opening to complete the weft insertion process. This method ensures stable weft insertion and is suitable for high-speed weaving.
Depending on the different organizational structures of the fabric, air jet weaving machines can be equipped with crank sheds, cam sheds, multi-arm sheds, or jacquard sheds, with cam sheds being the most common standard configuration.
Air jet weaving machines can adopt four-bar linkage, six-bar linkage, or conjugate cam beating-up mechanisms to ensure stable weft density and improve weaving quality.
Warp let-off mechanism: Options include electronic semi-positive and semi-negative warp let-off or mechanical semi-positive and semi-negative warp let-off, ensuring even warp tension and improved weaving stability.
Take-up mechanism: Options include mechanical continuous take-up and electric take-up, with most domestic models using mechanical continuous take-up.
Air jet weaving machines usually use an external ground yarn supply rack, which can be equipped with 2 to 8 cones. They also come with an electric drum weft storage system to ensure precise weft yarn length measurement, improving the stability of weft insertion.
Modern air jet weaving machines widely use microcomputers to control core processes such as weft insertion, weft selection, warp let-off, and take-up. Loom parameters can be set via keyboard display screens, and the system includes intelligent functions like fault self-diagnosis and loom status monitoring, enhancing operational convenience.
Energy-saving and environmental protection: Utilizing energy-saving nozzles to reduce compressed air consumption and increase energy efficiency.
Intelligent upgrade: Integrating Internet of Things (IoT) and big data for remote monitoring and intelligent diagnostics, improving production management efficiency.
Adaptability to multiple varieties: Optimizing nozzle design to expand the range of weavable fabrics, meeting diverse market demands.
High speed and low vibration: Improving the frame structure to reduce vibrations during loom operation, thus enhancing stability.
Air jet weaving machines are an important type of modern shuttleless loom. With their advantages of high-speed weft insertion, intelligent control, low energy consumption, and low noise, they are widely used in apparel fabrics, home textiles, industrial fabrics, and other fields. With the development of energy-saving, intelligent, and networked technologies, air jet weaving machines are moving towards more efficient, environmentally friendly, and intelligent directions, bringing revolutionary changes to the global textile industry.
