Fabric: Fleece terry

Item: Knitted trouser

Size: 164

Fabric weight = 260 GSM

ISL = Inseam length = 73.5 cm

SA = Seam Allowance = 5 cm

FR = Front rise = 19.5 cm

SA = Seam allowance = 0 cm

WBH = Waistband height = 4 cm

SA = Seam allowance = 4 cm

½ thigh = 27.25 cm

SA= Seam allowance = 4 cm

Fabric consumption for Body / Doz.:

{(ISL + SA + FR + SA + WBH + SA) x (½ thigh + SA)} x 4 x GSM / 100,00,000 + 8% (Wastage and extra cutting) x Doz.

= {(73.5 + 5 + 19.5 + 0 + 4 + 4) x (27.25 + 4)} x 4 x 260 / 100,00,000 + 8% x 12

= 4.465 kg / Doz.

Fabric consumption for pocket / Doz. (If fabric Single jersey then use GSM like 160):

{(Pocket Length + SA) x (Pocket Width + SA)} x 4 x GSM / 100,00,000 + 8% (Wastage and extra cutting) x Doz.

= {(14 + 4) x (11.25 + 4)} x 4 x 160 / 100,00,000 + 8% x 12

= 0.228 kg / Doz.

Fabric consumption for pocket / Doz. (If shell fabric then uses GSM like 240):

{(Pocket Length + SA) x (Pocket Width + SA)} x 4 x GSM / 100,00,000 + 8% (Wastage and extra cutting) x Doz.

= {(14 + 4) x (11.25 + 4)} x 4 x 260 / 100,00,000 + 8% x 12

= 0.37 kg / Doz.

Total fabric consumption of trouser (if Pocket single jersey):

Body consumption + Pocket consumption

= 4.465 + 0.228

= 4.693 kg / Doz.

Total fabric consumption of trouser (if Pocket shell fabric):

Body consumption + Pocket consumption

= 4.465 + 0.37

= 5.063 kg / Doz.

Finally note that, using above formula we will get only fabric weight that is consumed by a garment. In the above formula, it didn’t include marker loss, fabric loss due to fabric width and fabric wastage (like dying loss, finishing loss etc.). When we purchase fabric we have to consider all of those parameter.
