3. Fabric Details
3.1 Main Fabric
- Fabric type: 100% Cotton Denim
- Weight: 12 oz
- Width: 62” (157 cm)
- Finish: Indigo dyed
3.2 Pocketing Fabric
- Fabric type: Cotton poplin
- Width: 44”
4. Fabric Consumption Calculation (Denim‑Specific Logic)
Denim fabric consumption is calculated in meters per piece, considering:
- Size base
- Fabric width
- Pocket & fly parts
- Marker efficiency ≈ 78–82%
4.1 Main Denim Fabric Consumption
Industry marker‑based consumption:
✅ Main Fabric Consumption (Before Loss)
= 1.55 meters / piece
4.2 Shrinkage & Cutting Allowance
Denim requires higher allowance due to:
- Relaxation shrinkage
- Washing shrinkage
- Cutting loss
Standard allowance applied: 6%
1.55 × 1.06 = 1.64 meters
✅ Approved Denim Fabric Consumption = 1.64 m / piece
5. Fabric Price & Cost
5.1 Denim Fabric Cost
Denim price: USD 3.80 / meter
(Bulk booking, mid‑range export quality)
1.64 × 3.80 = USD 6.23
✅ Main Fabric Cost = USD 6.23
5.2 Pocketing Fabric Consumption & Cost
- Pocket fabric consumption: 0.20 meter / piece
- Pocket fabric price: USD 1.20 / meter
0.20 × 1.20 = USD 0.24
✅ Pocket Fabric Cost = USD 0.24
6. Trims & Accessories (Denim‑Specific)
