Development Trend Of Air-Jet Looms In Textile Enterprises

Air jet looms have been introduced into China since 1980s, and have gradually become a leading type of shuttleless looms. After nearly 20 years of development, great progress has been made in all aspects of speed, width and adaptability. The domestic air jet looms have developed a large scale through technology introduction, cooperative production and independent development. The varieties and specifications of the looms have developed greatly, and they have entered a stable stage. With the automatic cutting weft, frequency conversion, electronic warp, electronic coiling and electronic dobby in the jet loom technology, the speed is obviously improved, the range of weaving is extended, the quality of the products is stable, and the quality of the products has been satisfied in China. Textile enterprises Weaving the needs of different fabrics.

The main gap with foreign models is loom speed and width. At present, the rotary speed of foreign looms is between 750 and 1000r/min, and the speed of domestic air-jet looms is 600 to 800r/min. The width can only reach 360cm at present. In addition, we still have a certain gap in human-machine intellectualization. However, in view of the user requirements in the domestic market, there is not much difference in fabric adaptability, weaving adaptability and loom maintenance operation compared with imported looms. The domestic air-jet looms can meet the needs of users to weave high quality fabrics.

In recent years, shuttleless looms have been developing vigorously both internationally and domestically. Air-jet loom At present, it is the fastest developing shuttleless loom. Air-jet looms show strong competitiveness and broad market prospects for its advantages of high speed, high efficiency, low noise, good fabric quality, convenient operation, advanced automation functions and leading electromechanical integration technology. According to statistics, our country has about one million looms and the proportion of shuttleless looms is still very low, and eventually weave high-quality fabrics. Spinning out 120 or 300 yarns is not easy. Weaving and making a suit of 10000 yuan is easier said than done, and most of them are imported looms, which is quite different from that of 80% of shuttleless looms in the world's advanced countries.

With China's accession to the WTO, in order to meet the challenges of economic globalization, the pace of technological transformation of textile enterprises has further accelerated. The technological transformation of China's textile industry has resulted in the trend of shuttleless looms instead of shuttle looms. In 2005, the import of air-jet looms imported by domestic textile enterprises accounted for 50% of the total imports of shuttleless looms. From this we can see that the demand for air-jet looms is urgent in textile industry, and the market potential of air-jet looms is huge. There are sticky layers in the parts of the sewing machine parts such as surface baking, electroplating and other surface treatment. Therefore, before assembling, according to the survey of hundreds of large and medium-sized textile enterprises in the country and many townships and public enterprises in the coastal areas, the annual demand for air-jet looms occupies 40% to 50% of the total demand of the new high-grade shuttleless looms. Developing trend Very broad.
