Consumption
determination of fabric is a very important term in textile sector. Since it
depends on fabric prices therefore accurate and closure consumption will reduce
fabric wastage which will be beneficial for us economically. So, we should keep
proper knowledge of fabric consumption properly.
Here
today I am going to present fabric consumption of a basic polo-shirt.
Fabric consumption of a polo-shirt is the sum of fabric consumption of different parts of polo-shirt:
- Fabric consumption for body part.
- Fabric consumption for Sleeves.
For calculating fabric consumption of a basic polo-shirt following measurement will be needed.
- Body Length
- ½ Chest
- Sleeve length
- Armhole
So, now consider
|
= 78 cm (For body length
allowance = 3+1.5 = 4.5 cm)
|
|
= 56 cm (For chest allowance =
2+2= 4 cm)
|
|
= 25.5 cm (For sleeve length allowance = 2+1.5= 3.5 cm)
|
|
= 51 cm (For sleeve opening
allowance = 2+1 = 3 cm)
|
|
= 160 (Lacoste)
|
|
= 8%
|
Fabric consumption per
dozen, (all measurement in cm)
Fabric Consumption Per Dozen
(Body length+ ½ chest) * 2 + (sleeve length + arm hole) * 2 * 12*160 + wastage %
10000000
=(78+56)*2+(51+25.5 )*2*12*160 + 8%
10000000
= 2.14 kg/dz +.171 =2.31 kg/dz
So, Fabric consumption of a polo-shirt = 2.31
kg/dz
Note: Here I have made consumption
of polo shirt which has a pocket. Here I did not mention collar and cuff
consumption because maximum time in a polo shirt there is used flat knit collar
and cuff.
Thread consumption of a polo shirt is the sum of thread consumption of different parts of polo shirt:
Bottom hem (flat lock) = 2756 cm
Sleeve hem=5480cm
Side seam=4218cm
Solder seam=768cm
Placket=592cm
Sleeve joining=4536cm
Neck joining=627cm
Rib collar=1998cm
Tag= 64 cm
Level =237cm
Button attaching =192 cm
Placket lock =192cm
Logo = 200cm
Total
thread of polo shirt
=2756+5480+4218+768+592+4536+627+1998+64+237+192+192+200
= 21860cm
=218.6 m
Now,
Unit price of fabric,
Yarn cost = $ 3.5 /kg
Knitting
cost = $ .20 /kg
Dyeing &finishing =$ 2/kg
Unit cost for per kg
fabric,
=Yarn cost+Dyeing & finishing+Knitting cost
=$ (3.5+0.20+2) = $ 5.7/kg
So, total fabric price,
=2.31 kg * $ 5.7
=$13.16
Accessories details for per
pieces,
Ø
Sewing thread= $.06

Level
ü
Main level= $ .05
ü
Care level= $ .02
ü
Size level= $ .01
Ø
Polybag= $ .03
Ø
Cartoon= $ .04
Ø
Wastage= $ .05
Total cost of accessories for per pieces,
=Sewing thread+Level+Polybag+Wastage+Cartoon
= $.06+$.08+$ .03+$ .04+$ .05 = $ .26
Total cost of accessories for per dozen,
= $ .26 * 12 = $ 3.12/ dz
Now total costing of men’s polo shirt
ü
Fabric price =$13.16
üAccessories =$ 3.12
ü
Cost of making (CM) =$ 4
ü
Profit 20% =
$ .20
Total cost,
= Fabric price +Cost of making +Accessories
=$ 13.16+$ 3.12 +$ 4+$ .20
=$ 20.48/dz
Cost of polo shirt per pieces,
=$ 20.48/12
=$1.70/pc
Final quoted price for Buyer = $ 1.70 / pc (FOB)
