Consumption
Quantity of raw materials required to produce a complete garment is called consumption.
- Fabric consumption
- Sewing thread consumption
- Button
- Zipper
- Elastic
- Twill tape
- Hanger loop
- Other Trims & Accessories
Calculation of fabric Consumption
Basic information relevant to consumption:
- Measurement with technical specification
- Style description
- Fabrics description
- Fabric width /weight
- Available fabric width: 35’’, 45’’, 50’’, 55’’, 60’’
- Washing shrinkage
Factors Affecting Consumption & Costing
- Yarn/ Fibre content
- Yarn count and type (carded or combed)
- Knitting pattern/Construction
- Finishing of fabric
- Type of dyes and chemicals to be used
- Tolerance in shade variation
- Any restriction on use of dyes and chemicals
- Lab test requirement
- Packing type and assortment
- Design and pattern of garments
- Matching instruction in case of Y/D and printed Fabrics
- Number of garments to be packed per poly, blister and carton
- Ply of carton and type of poly and thickness of poly
- Details of accessories and their sources
- Details of printing
- Details of embroidery
- Details of value adding work, if any
- Level of AQL
- Production lead time
- Quantity of garments
- Number of color and size in the order
- Size and color ratio
- Tolerance in measurement
- Inspection authority
- CM
- Any hidden losses/costs
Consumption for Knit
Consumption formula:
L+SL+AL ½ C+AL GSM
---------------X-----------------X----------------X 2 X 12+W%
100 100 1000
- L = HPS/CBN/BL
- SL= Sleeve Length
- AL=Allowance
if, Body Length = 62 cm
½ Chest = 48 cm
Sleeve Length = 12 cm
Neck width = 19 cm
Rib Height = 1.5 cm
GSM for body fabric = 180
GSM for Neck rib = 220
- Body fabric Consumption:
( 62+ 12 + 10) ( 48+ 4) 180
-------------------X-------------X---------X 2 X 12+12%
100 100 1000
= (1.89 + 12% )kg/dz
= 2.12 kg/dz
- Neck Rib Consumption:
Width = Neck width x 2 + 2 cm (Round)
= 19X2+2 = 40 cm
Total Height = Rib Height X 2 + Allowance
= 1.5X2 +2=5 cm
( Length in cm X Width in cm X GSM X 12 )
Consumption (Kg/ dz) = ………………………………………………………….... + Wastage%
107
= 40X 5X220/10000000 X 12+15%
= (.053 +
15% )kg/ dz
Total consumption = (body consumption + Neck rib consumption)
=(2.12+.061)
= 2.18 kg/dz

Consumption calculation for woven basic pants
- ½ Waist Cir = 46cm+8 cm = 54 cm
- Front Rise = 28 incl.WB+8cm =36 cm
- ½ Thigh Cir = 36 cm+6 cm =42 cm
- Inseam =82 cm+4cm =86 cm
- Fabric width =(60-1)=59 inch
Consumption per piece
