Thread Consumption of Woven Shirt:
Thread consumption is very important for the T-shirt manufacturing process. In today’s competitive marketplace, there is a need for tight cost control of products. Besides, it is important to know the amount of thread consumed in a sewn product. To determine thread consumption you just need to multiply seam length with that factors. Thread consumption of a full sleeve shirt is given below.
Thread Consumption of a Full Sleeve Woven Shirt:
Formula = M x SQ x TPI x P
Where,
M- Measurement
SQ- Sewing Quantity
TPI- Thread per inch
P-Part:
Thread consumption for different component of a shirt
Collar,
L = M X SQ X TPI X P
= 16 X 2 X 2.5 X 1
= 80 Inch
W = 3 X 2 X 2.5 X 2
= 30 Inch
Collar band,
L=16 x 4 x 2.5 x 1
= 160Inch
W =1 X 2 X 2.5 X 2
=10 Inch
Shoulder:
L = 8 X 2 X 2.5 X 2
= 80 Inch
Arm hole:
L = 20 X 2 X 2.5 X 2
= 200 Inch
Over lock (O/L) = 20 X 1 X 9 X 2
= 360 Inch
Cuff:
L = 10 X 4 X 2.5 X 2 =200 Inch
W = 2 X 4 X 2.5 X 2 =40 Inch
Pocket:
L = 5 X 1 X 2.5 X 2 = 25 Inch
W = 5 X 1 X 2.5 X 2 = 25 Inch
Upper Placket:
L = 6 X 1 X 2.5 X 2 =30 Inch
W = 1 X 2 X 2.5 X 2 =10 Inch
Lower Placket:
L = 5 X 2 X 2.5 X 2 = 50 Inch
W=5 X 1 X 2.5 X 1 = 12.5 Inch
Box plate:
L = 30 X 2 X 2.5 X 1
= 150 Inch
Button plate:
L = 30 X 1 X 2.5 X 1
= 75 Inch
Label:
L = 1.5 X 2 X 2.5 X 3
= 22.5 Inch
Yoke:
L = 21 X 1 X 2.5 X 1
= 52.5 Inch
Side seam:
L = 20 X 1 X 2.5 X 2
= 100 Inch
Hem:
L = 48 X 1 X 2.5 X 1
= 120 Inch
Button hole:
= Part X Required thread per part
= 13 X 6
= 78 Inch
Button attach:
= Part X Required thread per part
= 17 X 5.5
= 93.5 Inch
Under Sleeve:
L = 21 XC 1 X 2.5 X 2
= 105 Inch
Over lock (O/L) = 21 X 1 X 9 X 2
= 378 Inch
TOTAL = 2487 Inch/69 yds/ 63.30 meter
With wastage (20%) = 63.30 + 12.66
= 76 meter
For 500 pieces of shirt,
76 X 500 = 37980 meter
Let, 3000 meters sewing thread are in each cone.
No of cone = 37980/3000
= 13 Pieces cone
