Water jet loom is a kind of shuttleless loom which uses water jet to pull the weft yarn through the shuttle opening. Its working principle mainly relies on water as the weft-inducing medium, the weft yarns are brought into the bobbin mouth through the water beam, and then the weft-beating mechanism drives the reed to beat the weft yarns entering the bobbin mouth into the weaving mouth and weave the cloth. This type of loom has the advantage of high rotational speed and high requirements for the main drive motor due to its easy weft draw-in system and high strength of warp yarn raw material. The control system of water jet loom is another important part of the loom, which is mainly responsible for ensuring the normal work of the loom and accomplishing the tasks of quick start, positioning brake, fault detection, electronic weft storage, electronic warp feeding and electronic winding of the water jet loom. The control system takes CPU as the control center, and after analyzing and processing, the control is carried out through the executive components.

Water jet loom occupies an important position in the field of filament weaving, especially suitable for chemical fiber filament weaving, especially hydrophobic filament weaving such as polyester. This is because the friction traction of water jet weft leading is greater than that of air jet weft leading on the weft yarn, less diffusive, and more adapted to the smooth surface of synthetic fibers, glass fibers and other filament weft leading. At the same time, water as a medium can also increase the conductive properties of synthetic fibers, effectively overcome the problem of static electricity in the weaving. Water jet loom weft flight speed, loom speed are among the first of all types of looms, so that it has a significant advantage in the textile industry.

The development and technical level of water jet loom, the five major movement mechanism (opening, weft leading, weft beating, winding, warp feeding) of the basic principles and main technical features, auxiliary agencies and auxiliary equipment, the principle of electronic control circuit, production technology management, weaving capacity of the configuration, the causes of operational failures and elimination of the weaving process settings and adjustments, product development and the elimination of common fabric imperfections, etc. are all the use of its use and maintenance of the important content. The use and maintenance of the machine is a major part of its operation and maintenance. The in-depth understanding and correct application of these aspects are of great significance for improving the productivity of water jet looms, product quality and reducing production costs.
