Woven Sack Manufacturing Formulas | GSM, Denier, Bag Weight & Production Calculation

Introduction

PP woven bag manufacturing industry me accurate calculation bahut important hota hai.

Is article me hum GSM calculation, denier calculation, bag weight, tape plant output aur production formulas ko simple language me samjhenge.

• Fabric Width Conversion

Fabric width (meter) = Fabric width (inch) × 0.0254

👉 Inch ko meter me convert karne ke liye use hota hai.

• Fabric GSM Calculation

Fabric GSM = (Warp Denier × Warp Mesh + Weft Denier × Weft Mesh) / 228.6

👉 Is formula se theoretical GSM calculate karte hain.

• Picks Per Meter (PPM)

Picks per meter = Weft mesh × 39.37

👉 Weft mesh ko meter me convert karta hai.

• Warp Tapes Required

Warp tapes required = Size (inch) × Warp mesh × 2

👉 Circular loom me total warp tapes nikalne ke liye.

• Fabric Weight per Running Meter

Fabric weight (gm/m) = GSM × Fabric width (m)

👉 1 meter fabric ka weight.

• Bag Weight Calculation

Bag weight (gm) = Fabric GSM × Finished width (m) × Cut length (m)

👉 Finished bag ka theoretical weight.

• Bags Per Hour

Bags per hour = Loom production (m/hr) ÷ Cut length (m)

👉 Loom kitne bags per hour bana raha hai.

• Warp Consumption Per Bag

Warp consumption (gm) = (Warp denier × No. of warp tapes × Cut length (m)) / 9000

👉 Ek bag me warp ka total weight.

• Weft Consumption Per Bag

Weft consumption (gm) = (Weft denier × Picks per meter × Finished width (m)) / 9000

👉 Ek bag me weft ka total weight.

• Tape Plant Required Output

Tape plant output (kg/hr) = (Loom fabric production (m/hr) × Fabric width (m) × Fabric GSM) / 1000

👉 Loom ki requirement ke hisab se tape plant output.

• Tape Line Output

Tape line output (kg/hr) = (Denier × No. of tapes × Line speed (m/min) × 60) / 9000000

👉 Tape extrusion plant ka actual production.

• Bags Per Shift

Bags per shift = Bags per hour × Shift hours

• Fabric Roll Length

Fabric roll length (m) = (Roll weight (kg) × 1000) / (Fabric GSM × Finished width (m))

👉 Roll me kitna meter fabric hai.

• Cutting Loss %

Cutting loss (%) = (Theoretical bag weight – Actual bag weight) 

                   / Theoretical bag weight × 100

👉 Cutting ke baad weight difference percentage.

• Practical Example (780 Denier Case)

Suppose:

Warp Denier = 780

Weft Denier = 780

Warp Mesh = 10

Weft Mesh = 10

Fabric GSM = (780×10 + 780×10) / 228.6

= 15600 / 228.6

= 68.24 GSM (Approx.)

👉 Is tarah aap theoretical GSM check kar sakte hain.
