Verified Mathematical Model & Formulation
Production (kg/hr) = (Feeders × RPM × Stitch Length (mm) × Efficiency % × 60) / (Count (Ne) × 1,693,400)
Calculates the rate at which yarn is converted into knitted fabric based on cylinder rotational speed, active yarn insertion feeders, and yarn mass per meter.
Configurable Parameters & Standard Units
- Machine Speed (RPM): (Default: 26 count)
- Number of Feeders: (Default: 96 count)
- Yarn Count (Ne): (Default: 30 count)
- Machine Efficiency (%): (Default: 85 percent)
Standard Worked Example & Practical Verification
Scenario: Running at 28 RPM with 96 feeders, 30s Ne yarn, 2.9 mm stitch length, and 85% plant efficiency.
Calculated Solution
17.5 kg / Hour (140 kg / 8-Hour Shift)
Practical Takeaway: Produces approximately 420 kg of single jersey fabric in a 24-hour day.
Frequently Asked Questions
What is typical efficiency for a circular knitting mill?
Well-maintained circular knitting mills typically operate between 82% and 90% overall efficiency, accounting for roll unloading, yarn package creeling, and lint cleaning stops.
