Air jet looms are used in the industry for production of high quality apparel fabrics and mostly for denim fabrics. Indian companies are producing fabric in millions of metres per annum while the export potential still remains weak. The main reasons for poor exports are quality of fabric not compatible with world class manufacturing with cost effective weaving, subjective decisions in four point fabric inspection system, urgency of delivery due to low production and retention of skilled manpower in a particular industry. Based on shop floor experience, we can avoid aforesaid faults by maintaining a system with regular follow up.
We will discuss the settings for Tsudakoma looms in supporting examples while implementation in other looms like Toyota Air jet weaving, Picanol Air jet weaving etc can be made with the help of Machine Manufacturers Manual, with some changes.
Weavers Beam Preparation:
Warping and sizing of beam needs full precaution and follow up of technical parameters. Correct selection of sizing ingredients and use of the same in adequate quantity with specified temperature, humidity, and concentration is very important to make beams. For economic and effective sizing, steam and air leakage must be attended to during the maintenance schedule.
Beam Gaiting or Knotting: Gaiting and knotting are important processes to prevent warp breakages and significantly affect the efficiency and quality of fabric.
Air Jet Looms:
Maintenance Checklist (Frequency can be maintained six monthly/annually) depends upon RPM of loom and follow up of outcomes.
If any loom works less efficiently, produces bad quality fabric, or breaks down more than expected, it needs preventive maintenance till such problems are overcome.
