Textile Floor │Fabric consumption formula for Trouser

Fabric which is required to produce a trouser/pant  is called consumption of trouser/pant. How much fabric is needed to produce trouser, we can determine it through marker planning or a suitable mathematical expression.

Suppose, 
One of Trouser’s Front rise (12.5+1) inch,
Back rise (15.5+1) inch,
Thai (Dia) (12+0.5) inch,
In-seam (27+1) inch
and G.S.M 180.
Now determine the fabric consumption for the basic Trouser.
Solution:
Here, Front rise = (12.5+1) inch,
Back rise = (15.5+1) inch
Thai (Dia) = (12+0.5) inch
In-seam = (26.5+1) inch
G.S.M = 180

According to formula–

Fabric length = [(Front rise + Back rise) / 2 ]+ length Inseam
= [(13.50 + 16.50) / 2] + 27.50
= 30/2 + 27.50
= 15 + 27.50
= 42.50 inch
Fabric width = Thai×4
= 12.50×4
= 50 inch
Total Fabric consumption = (180*50*42.50)/(1000*1550) kg
= 382500/1550000 kg
= 0.246774 kg
The amount of fabric is just for 1 piece. Generally 12 pieces are calculated with one.
Fabric consumption for 1 Dozen Trouser = 12×0.246774kgs
= 2.961 kgs
So, Fabric consumption for 1 Dozen 2 kgs and 961 gms.
