I. Heald frame structure

The water jet weaving machine is a widely used weaving machine for fabric production. It usually consists of a heald frame, a water jet, a yarn conveyor, a weft arrangement, a weft cutter and a fabric pick-up device. The heald frame is one of the most important components, which usually consists of an upper and lower frame and an internal heald cylinder. In order to improve the quality of the fabric and production efficiency, the modern water jet loom heald frame structure continues to develop, usually using multi-level, layered spacing small structure, can effectively increase the tightness and stability of the fabric.

II. Fabric layering technology

Fabric layering technology refers to the weaving process, the fabric is divided into a number of layers, respectively, after weaving and adjusting, and then combined into a layer of technology. This process can effectively solve the problem of uneven thickness of the fabric, uneven line density, improve the strength of the fabric, torsion and feel. In the water jet loom, layering is usually realized by changing the position of the water jet nozzle, water jet pressure and adjusting the heald frame pressure.

III. Fabric quality control

Fabric quality control is the most important part of the layering process. It mainly includes the control of fabric quality, line density, thickness and correction of frame tension. In order to maintain the stability of the quality and density of each layer of fabric, the need to use sophisticated electronic control system, the weaving process of the parameters for accurate monitoring and adjustment. At the same time, it is also necessary to grasp the change rule of the tension and line density of the heald frame, adjust the water spray pressure and heald frame pressure in time, and realize the adjustment and optimization of the quality of the fabric.

Ⅳ. The advantages of layering process and realize the way

Layering process can make the fabric thickness uniformity, strength and stability, and make the fabric surface smooth and flat, has a wide range of application prospects. Its realization mainly includes mechanical, gas jet type and electronic control type. Among them, electronically controlled layering process in the modern water jet loom in the most widely used, with a high degree of automation, fabric quality control precision and other advantages.

In short, the water jet loom opening frame layering process is one of the important processes of modern water jet loom production, which can effectively improve fabric quality and production efficiency, and realize the sustainable development of enterprises.
