= Allowance |
Allowance-01:This is actually sewing allowance in length wise of a garment.
For T-Shirt,
| Bottom Hem |
= 2.5-3 Cm |
| Shoulder Join |
= 1.5 Cm |
| Sleeve Hem |
= 2.5- 3 Cm |
| Sleeve Join |
= 1.5 cm |
| Sub Total |
= 9 cm |
| In Hand |
= 1 cm |
| Grand Total |
=10 cm |
Per Cut and Sewn allowance = 2 cm
Note: Pocket, Half moon, double layer bottom hem, and double layer sleeve s/b calculated onlengthwise.
2. Chest Allowance: This is sewing allowance in width wise of garment
a.Side Seam = ½ Chest + 3cm
b.Tube Seam= ½ Chest + 0 cm
c.Per cut and sewn allowance= 2 cm2.
Consumption (Kg/ Doz)= Length in Meter X Width In M X GSM in Kg X 2 X 12 + WastagePercentage
3. Neck Rib # 1x1/1x1 elastane rib circular
Neck Rib Consumption:
Height (Length) = Rib height or rib width or rib depth
Total Height= Rib Height X 2 + Allowance
Width = Neck opening or neck width x 2 + 2 cm (Round)
= Neck opening or neck width x 2 + 5 cm (V-shape)

= 19X2+2 = 40 cm
Total Height= Rib Height X 2 + Allowance= 2X2 +2=6 cm
| 2. Consumption (Kg/ Doz) |
= Length in Meter X Width In M X GSM in Kg X 12 + Wastage

Note:
Following point s/b considered during marketing cost:
1.Fleece dia is not available.
2.Y/D stripe wastage is huge
Math 02
Question: Fabric Length 100yds width 58 inch (Open) GSM 230, what is fabric weight?
Ans:Fabric weight in Kg = Length (Meter) X Width (Meter) X GSM in Kg
| W (Kg) |
= l x w x GSM= (100 Yds X36 X 2.54)/100 X (58 X 2.54)/100X 230/1000
= 91.44 x 1.4732 x .230
= 30.99 kg |
2.Question: Fabric weight 50 kg, Fabric width 40 inch (tube) GSM 180. What is fabric length in meter?
Ans:Fabric weight in Kg = Length (Meter) X Width (Meter) X GSM in KgW (Kg) = l x w x GSM
50 = l x (40x 2.54x 2)/ 100 X 180/1000
| L |
= 136.70 meter
= 136.70 x 1.0937 yds [ 1 meter = 1.0937 yds]
= 149.50 yds |
3.Question: Fabric price 2.25 USD/ yds, Width 45 inch open, GSM 200,Consumption 3.20 kg / doz, what is the garment fabric cost for per doz garments?
| Ans: W (kg) |
= L (M) X w (M) X GSM (kg)
= L (M) X (45X2.54)/100 X 200/1000 |
| L (M) |
= (3.20 X100X 1000) / (45X 2.54 X 200)
= 13.99 (M)
= 13.99 X 1.0937 yds
= 15.30 yds |
| Fabric cost (Per doz gmt) |
= Length X Unit price/ yds
= 13.99 (M)
= 15.30 x 2.25
= 34.56 USD / Doz |
Piping or Binding or Back Tape:
Cons: Length in M x width in M x GSM in Kg x 12 + allowance (18%)
Length: Neck width x 2 + 2 (R shape)
Width: If width is 1 cm or any unit Pls multiply by 4
