The weft insertion of the water jet loom uses water flowing in one direction as the weft insertion medium, which is beneficial to the high speed of the loom. Among several shuttleless weft insertion looms, the water jet loom is the one with the highest speed and is suitable for fabric processing of large quantities, high speed and low cost.
1. What is the water jet loom?
The water jet loom is a shuttleless loom that uses a jet of water to pull the weft yarn through the shed. The frictional traction force of water jet weft insertion on weft yarn is larger than that of air jet weft insertion, and the diffusivity is small, which is suitable for the needs of filament weft insertion such as synthetic fibers and glass fibers with smooth surface. At the same time, it can increase the electrical conductivity of synthetic fibers and effectively overcome the static electricity in weaving. In addition, jetting the weft yarn consumes less energy and has the lowest noise.

2. What are the features of the water jet loom?
The weft insertion of the water jet loom uses water flowing in one direction as the weft insertion medium, which is beneficial to the high speed of the loom. Among several shuttleless weft insertion looms, the water jet loom is the one with the highest speed and is suitable for fabric processing of large quantities, high speed and low cost.
3. What is The Difference Between Water Loom and Air Loom ?
The water jet loom uses water as the medium, and uses high-pressure water flow to bring the weft yarn from one end of the loom to the other. The suitable products are relatively thin, and the raw materials are hydrophobic, such as polyester, nylon, acrylic and other chemical fibers, which can be made with a water jet loom.
The air jet loom uses air as the medium, and use high-pressure airflow to move the weft from one end of the loom to the other. The adaptability of the product is wider than that of water jet, and it can be made of chemical fiber, polyester-cotton, and cotton.
4. Technology Status
1. Speed increase
The conventional speed has been increased from over 500r/min to more than 800r/min, and the production speed of some models can reach 900r/min -1200r/min.
2. Variety breakthrough
In the 1980s, the water-jet looms were mainly used for weaving nylon spinning and polyester and flat spinning. With the rapid development of synthetic fiber imitation silk plus technology, there have been great breakthroughs in the limitations of varieties, mainly in the following aspects.
① Double jet, free color selection and high-speed dobby loom make the products colorful:
Due to the breakthrough of the high-speed technology of the dobby opening mechanism and the successful research and promotion of the double jet and free color selection technology, the current water jet looms can weave twill, satin and ternary weave changes, and can weave It can also make sliver and plaid fabrics, and can also weave small pattern fabrics. The weaving fabrics are colorful and ever-changing.
② From the weaving of a single conventional fiber, to the development of differentiated fibers and the weaving of artificial silk and wool-like fabrics
Carry out technological innovation in the water jet loom, increase the development of hydrophilic fiber fabrics, change the production pattern of a single synthetic fiber, and realize the diversification of raw materials. And the way of interweaving, promoting strengths and avoiding weaknesses, so that the fabric not only has the breathability and comfort of natural fibers, but also has the characteristics of stiffness, wrinkle resistance and high strength of chemical fibers, which will improve the product grade and obtain higher economic benefits. Due to the breakthrough of weaving raw materials, the limitations of water jet loom weaving are greatly reduced.
③From weaving thin fabrics to thin, medium and thick weaving
The silk products woven by the water-jet loom, especially the wool-like silk products, are developing towards the thick type. The water-jet loom has been reinforced with the frame and the beating-up mechanism has been improved, so that the thick and heavy fabrics can be woven very smoothly on the water-jet loom. , wool-like silk, heavy synthetic fiber silk, heavy-duty hemp-like heavy silk can be weaved on the water jet loom.
④The width of the fabric gradually widens
In the past 20 years, the water jet loom has been developed with the support of the demand for variety development and the improvement of loom design technology. It is used to produce home textile products, such as curtains, bed sheets, tablecloths, etc. It can also be used for double-width weaving of clothing fabrics.
5. Adaptability of water jet loom:
1. It is usually used for fabric processing of hydrophobic fibers, and the processed fabric should be dried.
2. On the water jet loom, the weft yarn is pulled by the one-time jet jet of the nozzle, and the rapid decay of the jet flow velocity according to the exponential law hinders the expansion of the loom width. Therefore, water jet looms are often used for narrow or medium fabric processing.
3. It can be equipped with a dobby opening device, which is used for the processing of high-density and small-pattern weave fabrics. The weft selection function of the water jet loom is poor, and it can only be equipped with three nozzles at most for double-weft or triple-weft weaving.
6. Recommended Rotor Spinning :
(1) TONGDA Water Jet Loom TDW8100
TDW8100 is the most advanced model at present. It is suitable for making Youngor, Romon and other fabrics. The height of the integrated wall panel is 900, and the eccentric beating axis has less vibration. More than 800 rpm, using widened beam, more stable.
(2) TONGDA Water Jet Loom TDW508. TDW408
TDW-408 heavy water jet loom is the new model of the company, the frame of the whole machine is enlarged, which expands and the area of support of the beam. Therefore, the stability and aseismicity of the machine are greatly increased. The stability of beating-up is highly enhanced which guarantee the high quality of fabric.
