Fabric Consumption Calculation

Fabric Consumption Calculation. Basic formula: To estimate fabric consumption for a knitted top use following formula. Consumption in grams= {(L*C) + (C*SL)}*2*GSM/10000 (C*SL)}*2*GSM/10000 grams (when length units are i n centimeter) Where, C= Chest +allowance L= length of the body measure + allowance SL= Sleeve length +Allowance B=Biceps +allowance GSM = fabric weight in grams per square meter Example: Product - knitted top. Garments components are front, back and sleeves. Measurements without allowances

Measurement with allowances

Chest (C) = 23.25” Body Length (L) = 30.5” Sleeve Length (SL) = 26” Bicep (B) = 9.2”

+1.75” = 25” +2.50” = 33” +1.50” = 27.5” +0.80” = 10”

Fabric GSM =200

As per above formula consumption of fabric for this style is = {(L*C) + (B*SL)}*2*GSM/10000 (B*SL)}*2*GSM/10000 grams = [{(33*25) + (10*2*27.5)}*2*(2.54*2.54)*200]/100 (10*2*27.5)}*2*(2.54*2.54)*200]/10000 00 grams (Note: 2.54 is inch to cm conversion factor) = [{825+550}*400*6.45]/ [{825+550}*400*6.45]/10000 10000 grams = 354.83 grams Note: The above formula will give you only weight of fabric that i s consumed by a garment. In the above

formula, I did not included fabric loss due to fabric width, marker loss and fabric wastage (such as end loss, end bits, defects). When you purchase fabric you have to consider all of these parameter. To use calculation sheet download the following file. 1 inch = 2.54 CM
