1. Hardware: Low Entry
• Full-process PLC + touch screen: Just like using a mobile phone, select the process and start heating, spraying, circulation pump, fabric manipulation, and fabric discharge with one click.
• Automatic end-finding and fabric jam alarm: A magnetic fabric end detector and motor reversal function prevent fabric jams and downtime even for novice operators.
• Fabric guide roller-less design: Eliminates the two major difficulties of traditional J-type cylinders: tension adjustment and fabric guide roller wrap angle, reducing the number of operating steps by approximately 30%.
2. Process: Medium-High Entry
• The bath ratio of 1:2.5-1:4 has an extremely narrow dye/auxiliary concentration window; even the slightest deviation will result in color shifts; repeated proofing is required to establish a "fabric-dye-auxiliary-bath ratio" database.
• The nozzle angle, circulation pump frequency, and fabric manipulation amplitude are linked together, requiring real-time fine-tuning based on fabric thickness and weight. Empirical parameters are often not readily adaptable. • Although the heating/cooling rate (5°C/min) is automatically controlled by the system, excessively rapid cooling can still cause wrinkles or creases, requiring manual intervention to fine-tune the steam/cooling water valves.
3. Current Training and Support
• Equipment manufacturers typically provide a "2-day on-site + 7-day remote" training program: the first day covers startup and troubleshooting, and the second day covers process fine-tuning.
• 90% of users can independently run conventional processes within one week; however, for demanding products such as high-stretch knits and ultra-fine polyester, an additional 2-4 weeks of hands-on training are required.
4. Difficulty Comparison
Rotary Table Dyeing Machine ≈ Linear Dyeing Machine < O-Type Dyeing Machine < Airflow Dyeing Machine
O-type dyeing machines have simpler hardware than traditional J-type dyeing machines due to their lack of guide rollers and lower liquor ratio. However, due to their narrower process window, they require slightly more experience than J-type dyeing machines.
