In the past 30 years, great progress has been made on water jet loom technology in the world.
1. Breakthrough in raw materials and varieties
Due to the needs of the market and the development of the world's synthetic fiber technology, the breakthrough of varieties and raw materials is imperative. The technological advancement of water jet loom has made it possible to break through varieties and raw materials. The varieties and raw materials of water jet weaving have evolved from single and conventional polyester and nylon to the development of differentiated fibers and weaving of simulated silk and wool-like fabrics: In the past to use 75dtex
(68 denier), 77dtex (70 and), 110dtex (100 denier), 165dex (150 denier) and other conventional polyester yarns and nylon yarns are mainly weaved, and now we can not only carry out conventional silk weaving, but also carry low-elastic yarn and strong Weaving of silk and twisted yarn; not only can we weave ordinary silk, but also
Weaving fine-denier filament, ultra-fine denier, and split-type superfine filament; not only can we perform single fiber weaving, but also weaving of composite yarn and wrapped yarn, so that peach skin, suede and stretch fabric appear in large quantities. Raw materials are the basis for variety development, advances in weaving technology, and weaving
There is a big breakthrough in the variety of raw materials, which greatly reduces the limitations of the weaving machine. Fabrics have also evolved from the production of thin fabrics to thin, medium and thick fabrics, as well as twill, satin and jacquard fabrics.
2. The application of new technologies is maturing
In recent years, the water jet loom has changed the one-color latitude of the past, which is mainly based on weaving single-spray. The double-spray and three-spray are widely used, and the two-color latitude and three-color weft can be woven. Weaving strong silk: The water jet loom produced by Japan Tsudakoma Co., Ltd. mechanically exposes the nozzle when weaving strong twisting
The front end of the weft is straightened backwards to avoid the kinking of the weft at the next weft, which improves the accuracy of the weft insertion. The gas suction device of the water jet loom produced by Toyota prevents the wefts from interacting with each other. Winding, weft insertion is more stable; the water jet loom produced by the above two companies has elastic yarn
Special weft insertion device. The water jet loom produced by Tsudakoma Co., Ltd., Shenyang Hongda Company and Qingdao Yunchun Co., Ltd. uses a double pump to achieve stable weft insertion of two kinds of wefts with very different fineness and characteristics, so that the development of water jet loom varieties has been developed. Greater possibility. Some water jet loom can be switched by swinging nozzles when weaving two-color weft, so that each nozzle is in the best position for weft insertion, which improves the stability of weft insertion.
3. Breakthrough of the opening mechanism
It creates good conditions for the expansion of the water jet loom. The cam-type opening mechanism frees the water jet loom from a single weft weaving, while the high-speed dobby machine enables the water jet loom to weave twill, satin and its varying texture, as well as to weave small pattern fabrics. Comprehensive wear
When the change is made on the raft, the variety of weaving is ever-changing, creating a colorful new world for the weaving machine weaving machine. These looms adopt three-spray three-color free latitude selection. In the past, only the condition of single weft thread can be woven, and the thickness adaptability of the thread has been further improved.
4. Increase in speed
Due to the adoption of mechatronics technology, the water jet loom manufacturer has improved the design of the pump structure (using ceramic water pumps), cams and nozzles. In particular, the water jet loom uses new nozzles and stabilizers to concentrate the water jets on the spray. On the water hole, the jet water is more concentrated. The use of such a nozzle reduces the water consumption, and also enables the water jet loom to be stably produced under conditions of a small opening and a small amount of water, improving the weft insertion ability, and supplementing with other technical measures to make the weaving loom of the water jet loom From the past 230cm to 350cm; the highly rigid box-shaped frame on both sides reduces the vibration of the loom during high-speed operation, because the vibration reduction can make the weft insertion and beating even more stable, ensuring the high quality of the fabric; The reinforcement of the frame and the beam enables the water jet loom to withstand a large beating force, thus creating conditions for the development of the woven fabric to the heavy fabric; its main transmission gear is oil bath lubrication to achieve high speed stability; The small shed weft insertion and less water volume further increase the speed of the car. The speed of normal production of loom has generally increased from 500~700r/min in the past to 700~900r/min, even up to 1200r/min.
5. Width and package increase
The nominal width of the water jet loom is supported by variety development and technological progress, from 110cm, 130cm, 170cm, 190cm to 230cm. In recent years, due to the increase of motor torque, the pump plunger size has increased, using electronic weft feeder , the speed is properly controlled at 400~450r/min, the looms are reinforced in the middle, and the slabs are used. Therefore, the nominal width is greatly improved, and the 290cm and 350cm extra-wide looms appear.
At the same time, the wide-width silk-receiving machine and the ultra-long long-axis are gradually appearing. The width of the large roller of the dividing warping machine reaches 350cm, and the width of the warping and the shaft reaches 230cm.
