The water jet loom is a shuttleless loom that uses a jet of water to draw the weft through the shed.
1. Development history
The development history of foreign water jet looms:
Invented period: The water jet loom was first invented by Czechoslovakia in 1955. The box width is only 1050mm and the maximum speed is close to 400rpmin.
Development period: In the 1960s, Japan Yuanzhou Company introduced Czech patents, imitated production, and publicly published the Lw water jet loom of Nissan Company.
Initiation period: In the 1970s, Japan Tsudakoma Company formed the ZW water jet loom
Growth period: The successful operation of Nissan and Tsudakoma in the 1980s.
The development history of domestic water jet looms:
1970s: Restructuring of water jet looms on shuttle looms
1980s: Produced a water jet loom with a box width of 1600mm and a speed of about 300rpmin. Shenyang Textile Machinery Factory and Japan's Nissan Co., Ltd. jointly produce GD761 water jet looms, with an annual output of only about 600 units. Qingdao Yunchun Textile Machinery Co., Ltd. cooperates with Taiwan to produce Jws00 water jet looms, with an annual output of about 1,000 units. .
At the end of the 1990s: In 1998, the total number of domestic water jet looms exceeded the imported number for the first time, reaching more than 2,800.
2. The principle of weft insertion
The water jet loom is a jet loom, which uses water as the weft insertion medium, and generates frictional traction on the weft through the jet of water, so that the weft on the fixed package is introduced into the shed. This makes the water jet loom have advantages in terms of speed, labor saving, and energy saving, but it is limited to weaving hydrophobic fabrics.
3. Variety adaptability
Water jet loom is a kind of high-speed loom commonly used in recent years, but its products are also limited. Many products cannot be produced, but the production efficiency for general interior fabrics is extremely high.
Suitable for the production of high-volume, high-speed, low-cost filament fabrics;
Hydrophobic fiber (polyester, nylon, glass fiber, etc.) fabric processing;
Water jet loom can only be used for narrow or medium fabric processing;
Can be equipped with multi-arm opening, weaving high warp density and small pattern weave fabric;
The weft selection function is poor, and it can only be equipped with two nozzles at most, mixed weft or two-color weft weaving.
