[0022] A water jet weaving machine production process comprises the following steps: S1. Preparation before drawing in; S1-1. Physical methods are used to remove impurities and defects on the yarn surface to ensure the purity of the yarn. Oiling treatment forms a lubricating film on the yarn surface to reduce the friction between yarns and between yarns and equipment, and reduce the breakage rate. Humidification treatment adjusts the moisture regain of the yarn to increase the flexibility and strength of the yarn, making it more suitable for drawing-in processing. S1-2, using a warping machine to wind the pretreated yarn onto a warp beam according to a certain arrangement and tension requirements, and by adjusting the parameters of the warping machine, such as the arrangement density of the yarn, the winding speed and the tension, etc., ensure that the yarn on the warp beam is evenly arranged and has consistent tension, thereby providing good conditions for subsequent drawing-in and weaving; S1-3. Check and clean all parts of the heald drawing machine, check whether the heald frame is flat, whether the healds are damaged or deformed, whether the drop wires can work normally, use a brush and detergent to clean the heald frame, healds and drop wires to remove dust and oil on the surface.

[0023] S2, drawing-in operation; S2-1. The drawing-in machine uses mechanical transmission and control devices to pass the yarn on the warp beam through the heald eyelets and the dropper piece in sequence. The drawing-in sequence of the drawing-in machine can be adjusted according to the requirements of the fabric structure. For example, the straight drawing method is to pass the yarn through each heald one by one in sequence; the flying drawing method is to skip some healds for drawing-in; the intermittent drawing method is to draw-in at a certain interval. Different drawing-in methods are suitable for different fabric structures to meet the structural and appearance requirements of the fabric. The drawing-in machine is used to pass the yarn on the warp beam through the heald eyelets and the dropper piece in sequence according to odd and even number groups; S2-2, after each group is completed, a high-pressure water jet is sprayed through the water spray device to fix the yarn arrangement; S2-3. The reed is a comb-like tool with a certain reed tooth density. The yarn with the heald and the drop wire is introduced between the reed teeth of the reed. The function of the reed is to determine the width and warp density of the fabric. By selecting reeds with different reed tooth densities, fabrics of different specifications can be produced.

[0024] S3, tension adjustment; The tension adjustment device adjusts the tension of the warp yarn so that the tension of each warp yarn remains uniform and meets the weaving requirements. The tension adjustment can be achieved by changing the degree of stretching of the warp yarn, adjusting the pressure of the tension disk, etc. Uniform warp yarn tension helps to ensure the flatness and quality of the fabric.

[0025] S4, quality inspection; A combination of manual visual inspection and measuring tools is used. Manual visual inspection can directly observe the threading of the warp yarn, such as whether it is missed or wrongly threaded. With the help of measuring tools, such as tension meters and calipers, it can be tested whether parameters such as the warp yarn tension and arrangement density meet the requirements, so as to discover and correct problems in a timely manner.

[0026] S5, on-machine debugging; Run the loom with the yarn threaded on it for a preliminary run to check whether all parts of the loom are working properly, such as whether the opening movement, weft insertion movement, and weft beating movement are coordinated. By adjusting the loom parameters, such as machine speed, warp tension, weft tension, etc., the loom can reach the best operating state and prepare for formal production.

[0027] S6, sorting and rolling; The warp yarns that have passed the debugging are sorted, the excess thread ends are removed, and they are rolled and packaged according to certain specifications.

[0028] Specific steps: remove impurities and defects on the yarn surface by physical methods to ensure the purity of the yarn; oil treatment forms a lubricating film on the yarn surface to reduce the friction between yarns and between yarns and equipment, and reduce the breakage rate; humidification treatment is to adjust the moisture regain of the yarn to increase the flexibility and strength of the yarn, making it more suitable for drawing-in processing; use the warping machine to wind the pretreated yarn onto the warp beam according to a certain arrangement and tension requirements; adjust the parameters of the warping machine, such as the arrangement density of the yarn, the winding speed and the tension, etc., to ensure that the yarn on the warp beam is evenly arranged and the tension is consistent, providing good conditions for subsequent drawing-in and weaving; and perform various parts of the drawing-in machine. Check and clean, check whether the heald frame is flat, whether the heald is damaged or deformed, whether the dropper can work normally, use a brush and detergent to clean the heald frame, heald and dropper to remove dust and oil on the surface. The heald drawing machine uses mechanical transmission and control devices to pass the yarn on the warp beam through the heald eye and dropper in sequence. The drawing-in sequence of the heald drawing machine can be adjusted according to the requirements of the fabric structure. For example, the straight drawing method is to pass the yarn through each heald one by one; the flying drawing method is to skip some healds for drawing-in; the intermittent drawing method is to draw-in at a certain interval. Different drawing-in methods are suitable for different fabric structures to meet the structural and appearance requirements of the fabric. The yarn on the warp beam is drawn in by the heald drawing machine. The odd-numbered and even-numbered groups pass through the heald eye and the dropper piece in turn. After each group is completed, a high-pressure water beam is sprayed through the water spray device to fix the yarn arrangement. The reed is a comb-like tool with a certain reed tooth density. The yarn that has passed through the heald and the dropper piece is introduced between the reed teeth of the reed. The function of the reed is to determine the width and warp density of the fabric. By selecting reeds with different reed tooth densities, fabrics of different specifications can be produced. The tension adjustment device adjusts the tension of the warp yarn to keep the tension of each warp yarn uniform and in line with weaving requirements. The tension adjustment can be achieved by changing the degree of stretching of the warp yarn, adjusting the pressure of the tension disk, etc. Uniform warp tension helps to ensure the flatness and quality of the fabric. Artificial Combining visual inspection with the help of measuring tools, manual visual inspection can directly observe the threading of the warp yarn, such as whether it is missed or wrongly threaded, etc. With the help of measuring tools, such as tension meters and calipers, it is possible to detect whether the warp yarn tension, arrangement density and other parameters meet the requirements, and timely discover and correct problems. The loom with the yarn threaded is put into preliminary operation to check whether the various components of the loom are working normally, such as whether the opening movement, weft insertion movement, and weft beating movement are coordinated.
