Air jet looms are used in the industry to produce high-quality clothing fabrics, and are mainly used for denim. Indian companies produce millions of meters of fabric every year, and the export potential is still weak. The main reason for poor export is the incompatibility of fabric quality with cost-effective weaving process, world-class manufacturing level, subjective decision of four-point fabric inspection system, and delivery urgency due to low output and retention of skilled personnel in specific industries . According to workshop experience, the above-mentioned failures can be avoided by regularly maintaining the system.
We will discuss the settings of the Tsudakoma weaving machine in the supporting example, and the implementation of other weaving machines (such as Toyota Air jet weaving, Picanol Air jet weaving, etc.) can be modified with the help of the “Machinery Manufacturer Manual”.
The warpage and size adjustment of beams require adequate preventive measures and follow-up technical parameters. The correct selection of sizing ingredients and the use of sufficient amounts of sizing ingredients at the specified temperature, humidity and concentration are very important for the manufacture of beams. In order to sizing economically and efficiently, attention must be paid to steam and air leaks during maintenance planning.
Knotting or knotting of beams: Knotting and knotting are important processes to prevent warp yarns from breaking and significantly affect fabric efficiency and quality.
The maintenance list (the frequency can be maintained at six per month/year) depends on the RPM of the loom and the follow-up of the results.
If any loom works inefficiently, produces poor-quality fabric or is damaged beyond expectations, preventive maintenance is required until such problems are overcome.
Using air-jet looms, with the help of microprocessor-based control, we can achieve higher efficiency and productivity. This means that the weaving team can analyze the following details in time and prevent losses in the gray stage:
7). According to the efficiency of the loom, the weaving meter, the inserted weft, the total running time of the loom, etc., perform production evaluation.
9). Graphical analysis to control production costs, various defects during the operation of the loom, etc.
If the weft yarn feels loose during the knitting process, it will be recognized on the display. In this way, the loom can be repaired before a specific part breaks. It has been observed that one of the other advantages of this facility is that if the reed screws remain slightly loose, the feeler gauge will vibrate when installed on the reeds, therefore, timely participation in the loom can avoid further damage.
By effectively tracking maintenance schedules and troubleshooting methods according to changing needs and market trends, most fabrics can be woven on air-jet looms with zero-defect fabrics. As long as regular maintenance and lubrication are properly carried out, the performance of the air-jet loom will not be reduced due to long-term use. The manufacturer has a large number of air-jet looms with microprocessor-based controls. The only limiting factor is that everyone must play a role and focus on the results.
