Woven fabric consumption formula.
Learn Apparel Merchandising, Learn Fashion design.
Before calculate the woven fabric consumption, you must need the followings information as mentioned below:
1) Measurement chart with technical spec.
2) Style Description.
3) Fabric Description.
4) Fabrics width/weight.
5) Washing shrinkage if any.
This formula is as under :
Formula = Length X Width / Fab width X Fab UnitHere,Length = length of the specific parts + allowanceWidth = width of the specific parts + allowanceFab width = Fabric width ( after considering the shrinkageallowance).Say, fabric width is 45″ & the shrinkageallowance is 1″, Then the Fabric width willbe (45″-1″) = 44″ in the formula.Fab unit = Fabric calculation unit, here it will be 36 becausewe are going to calculate the consumption inYards.
Now we will calculate the consumption of a Shirt (front part)Center front length = 32″+1″ (Sewing allowance) = 33″Width (Chest) = 24″ + 1″ (Sewing allowance) + 3″Pleat.W (1.5X2) = 28″
= Length X Width / Fab width X Fab Unit= 33″ X 28″ / 44″ X 36″= 924″ / 1584″= 0.5833333
= 0.59 Yards. (for front part)
