Development Trend of Air-jet Loom at Home and Abroad
Time:[2019-8-7]    Pageview:1359

Air-jet looms have gradually become a dominant type of shuttleless looms since they were introduced in large areas in China in the 1980s. After nearly 20 years of development, great progress has been made in speed, breadth and variety adaptability. Domestic air-jet looms have begun to take shape through technology introduction, cooperative production and independent development. The variety and specifications of looms have been greatly developed and have entered a stable stage. With the widespread use of automatic weft-breaking, frequency conversion speed regulation technology, electronic warp-let-off, electronic coiling and electronic dobby in air-jet loom technology, the speed is obvious. With the improvement of weaving adaptability and stable product quality, it has been able to meet the needs of domestic textile enterprises in weaving different fabrics. The main gap with foreign models lies in the speed and width of looms. At present, the speed of foreign looms is 750-1000 r/min, the speed of domestic air-jet looms is 600-800 r/min, and the width is only 360 cm at present. In addition, there is still a certain gap in the aspect of human-machine intelligence. The keyboard display is not as informative as that of foreign similar products. However, compared with imported looms, domestic air-jet looms do not lag far behind in fabric adaptability, weaving process adaptability and loom maintenance and operation. Domestic air-jet looms can fully meet the needs of users in weaving high-quality fabrics.

In recent years, shuttleless looms have developed vigorously both at home and abroad, and air-jet looms are a kind of shuttleless looms with rapid development. With a series of advantages such as high speed, high efficiency, low noise, excellent fabric style, convenient operation, automation function and mechatronics integration technology, air-jet looms have continuously shown strong strength. Competitiveness and broad market prospects, according to statistics, there are more than one million looms in China, the proportion of shuttleless looms is still very low, and most of them are imported looms, which is far from the 80% ownership of shuttleless looms in advanced countries in the world. With China's entry into WTO, in order to meet the challenge of economic globalization, the pace of technological transformation of textile enterprises has been further accelerated. The technical transformation of China's textile industry has formed the trend of replacing shuttle looms with shuttle looms. In 2005, the import of air-jet looms in domestic textile enterprises accounted for about 50% of the total import of shuttle-less looms. It can be seen that the textile industry is in urgent need of air-jet looms, and the market potential of air-jet looms is huge. According to the investigation and understanding of nearly 100 state-owned large and medium-sized textile enterprises and numerous Township and private enterprises in coastal areas, the annual demand of air-jet looms accounts for about 40%-50% of the total demand of newly added high-grade shuttleless looms, and the market prospect is very broad.
