Dear All,

For calculating the consumption of your knit garments please follow the below instruction. The following information you need at first, as listed below: 

(During the consumption please used measurement of middle size for calculation or used the size which has most of the qty. If the style has 6 sizes then used size number 04 for calculates the consumption. Here we will used size: "L" for calculate the consumption) 

i. Body length of the garments in cm. Suppose it is - 73 cm

ii. Sleeve length of the garments in cm. Suppose it is - 19.5 cm

iii. Approximate sewing allowance at body hem, shoulder joint, sleeve hem & armhole joint (in cm). Suppose it is - 10 cm 

iv. Chest width (1/2) in cm. Suppose it is - 52 cm

v. Approximate sewing allowance at both side seams (in cm). Suppose it is - 4 cm  

vi. Fabric GSM (finish). Suppose it is - 160 gsm 

vii. Approximate fabric wastage in various stages. Suppose it is - 10% 

(In this regards please note that, fabric wastage depend on how many additional elements the garments have, which may changed in any time. If the garment has rotary print, enzyme stone wash etc, then the fabric wastage will be more than normal wastage)

Rules: 

{(B/length + S/length + Sewing Allowance) X (1/2 Chest + Sewing Allowance)}X 2 X GSM X 12 / 10000000 + Wastage

= (102.5 X 56) X 2 X 160 X 12 / 10000000 + 10%

= 5740 X 2 X 160 X 12 /10000000 +10%

= 22041600 / 10000000 + 10%

= 2.20416 + 10 %

= 2.424576

= 2.43 kg per dozen. (Consumption)

Hope everything is now clear to all.
