Dear All,
For calculating the consumption of your knit garments pls follow the below instruction. The following information you need at first, as listed below:
(During the consumption pls used measurement of middle size for calculation or used the sizes which have most of the qty. If the style has 6 sizes then used size number 04 for consumption. Here we will used size: "L" for calculate the consumption)
Consumption of Basic T-Shirt:
i. Body length of the garments in cm. Say it is - 73 cm
ii. Sleeve length of the garments in cm. Say it is - 19.5 cm
iii. Approximate sewing allowance at body hem, shoulder joint, sleeve hem & armhole joint (in cm). Say it is - 10 cm
iv. Chest width (1/2) in cm. Say it is - 52 cm
v. Approximate sewing allowance at both side seam (in cm). Say it is - 4 cm
vi. Fabric GSM (finish). Say it is - 160 gsm
vii. Approximate fabric wastage in various stages. Say it is - 10%
(In this regards pls note that, fabric wastage depend on how many additional elements the garments have, which may changed in any time. If the garments have rotary print, enzyme stone wash etc than the fabric wastage will be more than normal wastage)
Rules:
(BL + SL + SA) X (1/2 Chest + SA) X 2 X GSM X 12
Formula = --------------------------------------------------------------------------- + Wastage%
100 x100 x 1000
= {(73 + 19.5 + 10) X (52 + 4) X 2 X 160 X 12} / 10000000 + 10%
= {(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)
