Current situation and development trends at home and abroad

Since air-jet looms were introduced on a large scale in China in the 1980s, they have gradually become a leading model of shuttleless looms. After nearly 20 years of development, there has been tremendous progress in terms of rotation speed, effective width, and variety adaptability. Domestic air-jet looms have begun to take shape through technology introduction, cooperative production, and independent development. The varieties and specifications of looms have made great progress and have entered a stable stage. With the automatic weft search, variable frequency speed regulation technology, and electronic let-off , electronic take-up and electronic dobby are widely adopted in air-jet loom technology, the speed has been significantly increased, the weaving adaptability range has been expanded, and product quality has been stable, which has been able to meet the needs of domestic fabric companies for weaving different fabrics. Among domestic air-jet looms, the ZA209i and GA710 of Jingwei Xianyang Loom Manufacturing Co., Ltd., the GA708 of China Fabric Machinery Co., Ltd., and the LA600 model of Shenyang Hongda Fabric Machinery Co., Ltd. are represented. Xianyang’s ZA and GA series models introduce technology from Japan’s Tsudakoma, and their basic configurations are basically the same as those of foreign models. The main difference with foreign models is the loom speed and effective width. At present, the speed of foreign looms is 750~1000r/min, the speed of ZA and GA series products is 600~800r/min, and the effective width is currently only 330cm. In other aspects, we still have a certain gap in terms of human-machine intelligence. Keyboard The amount of information displayed is not as large as that of similar foreign products. However, in view of the usage requirements of the majority of users in the domestic market, compared with imported looms, there is not much difference in terms of fabric adaptability, weaving process adaptability and loom maintenance operations. Domestic air-jet looms can fully meet the needs of users for weaving high quality products. Fabric needs. In recent years, shuttleless looms have been developing vigorously, both internationally and domestically, and air-jet looms are currently the most rapidly developing shuttleless looms. Air-jet looms are known for their high speed, high efficiency, low noise, excellent fabric style, and easy operation. , advanced automation functions, leading mechatronics technology and other advantages, they continue to show strong competitiveness and broad market prospects. According to statistics, there are more than one million looms of various types in my country, including shuttleless weaving. The proportion of shuttleless looms is still very low, and most of them are imported looms, which is far behind the 80% of shuttleless looms owned by advanced countries in the world. With my country’s accession to the WTO, in order to meet the challenges of economic globalization, the pace of technological transformation of textile enterprises has been further accelerated. The technological transformation of my country’s fabric industry has formed a trend of shuttleless looms replacing shuttle looms. In 2005, the import of air-jet looms by domestic fabric companies accounted for about 50% of the total imports of shuttleless looms. It can be seen from this that the fabric industry has an urgent demand for air-jet looms and the market potential of air-jet looms is huge. According to a survey of nearly a hundred large and medium-sized state-owned fabric enterprises in China and many towns and private enterprises in coastal areas, the annual demand for air-jet looms accounts for about 40% to 50% of the total demand for new high-end shuttleless looms. The market prospects Very vast.
