The working performance of high-speed tricot warp knitting machines has many characteristics:
1. High-speed operation:
Speed range: Generally, the machine speed is 700-1000 rpm, up to 4400 rpm. This makes its production efficiency extremely high, and it can complete a large amount of weaving work in a short time to meet the needs of large-scale production.
High-speed advantage: High-speed operation can increase the output per unit time and reduce production costs. For some production tasks with large orders and tight delivery time, high-speed tricot warp knitting machines have obvious advantages.
2. Diverse comb configurations:
Number of combs: Usually 2-4 combs are used, 6-10 in a few cases, up to 18. Different numbers of combs can weave fabrics of different complexity and style to meet the needs of various products.
Function of combs: The function of combs is to guide the yarn for weaving, and its number and arrangement determine the fabric structure and pattern style. More combs can achieve more complex pattern weaving, which makes it possible to produce diversified warp knitting products.
3. Higher machine gauge:
The commonly used machine gauge is 20-32 needles/25.4 mm, up to 40 needles/25.4 mm. Higher machine gauge means a higher needle density, which can weave finer and tighter fabrics, suitable for producing high-quality warp knitted fabrics.
4. Suitable working width:
The working width is generally 2130-4270 mm (84-168 inches), which can meet the production needs of fabrics of different sizes. A wider working width can improve production efficiency, reduce the splicing process in the production process, and is also conducive to the production of large-format warp knitting products.
5. Excellent performance of loop forming parts:
Transmission mode: The transmission of the loop forming parts has been changed from cam type to eccentric connecting rod type. The improvement of this transmission mode improves the running stability and weaving efficiency of the machine, and reduces the wear and failure rate of the parts.
Loop quality: In the groove needle warp knitting machine, the opening and closing of the needle mouth during the looping process is accurate, and the sinker can effectively hold the fabric to ensure that the old coil will not slide down to the needle bar as the needle rises, thereby ensuring the quality of weaving and the stability of the coil structure.
6. Advanced control system:
Warp feeding system: The use of mechanical or electronic-mechanical active warp feeding mechanism can accurately control the warp feeding amount of the warp yarn and ensure the stability of the warp yarn tension, thereby improving the quality of the fabric. Some new tricot warp knitting machines are also equipped with computer-controlled warp feeding systems, such as EBA and EBC, which make the warp feeding more accurate and reliable.
Pattern control: In addition to using pattern plates or cams, the pattern mechanism that controls the traverse of the comb bar is increasingly controlled by electronic programs. The accuracy and complexity of the pattern have been greatly improved, and it is also convenient for operation and adjustment, and the pattern can be quickly changed.
