Sewing thread consumption
For a disciplined garments costing, it’s very important issue to know sewing thread consumption. For making a garment, the needed amount of sewing thread or making seam is called sewing thread consumption.
Thread consumption varies between stitch types to stitch type.
Sewing thread |
- Stitch type-101(Single needle chain stitch)
- Stitch type-301(single needle lock stitch)
- Stitch type-401(single needle chain stitch)
- Stitch type-504(three thread over edge stitch)
<<For stitch type-101>>
Thread consumption (C) = 3 + 2TS
<<For stitch type-301>>
Thread consumption (C) = 2 + 2TS
<<For stitch type-401>>
Thread consumption(C)= 4 + 2TS
<<For stitch type-504>>
Thread consumption (C) = 3 + 4WS + 4TS
Here,
T = Seam thickness
S = Stitch density
W = Seam’s width
Mathematical Problem:-01
If the thickness of seam 0.005 and stitch number per inch is 9, Determine thread consumption for stitch type-101?
Solution:
Given that,
Thickness of Stitch (T) = 0.005
Stitch density (S) = 9 per inch
Thread consumption =?
We know , For stitch type-101
Thread consumption = 3 + 2TS
= 3 + 2 x 0.005 x 9
= 3.09 inch (ANS)
Mathematical problem:-02.
If thickness of seam and stitch density is respectively 0.01 and 10 per inch. Find out thread consumption for Stitch type-301?
Solution:
Given that,
Thickness of Stitch (T) = 0.01
Stitch density (S) =10 per inch
Thread consumption = ?
We know, For stitch type-301
Thread consumption (C) = 2 + 2TS
= 2 + 2 x 0.01 x 10
= 2.2inch (ANS)
Mathematical problem:-03.
Seam’s thickness 0.015 and Stitch density per inch 15, Then what amount of thread will be needed for making 1 inch of seam for stitch type-401 ?
Solution:
Given that,
Thickness of Stitch (T) = 0.015
Stitch density (S) =15
Thread consumption = ?
Thread Consumption (C) = 4 + 2 TS
= 4 + 2 x 0.015 x 15
= 4.45 inch (ANS)
Mathematical problem:-04.
For Stitch type-504, determine thread consumption for seam thickness 0.02, stitch density 15 per inch and seam’s width 1/4ʹʹ ?
Solution:
Given that,
Thickness of Stitch (T) = 0.02
Stitch density (S) =15
Width (W) =1/4ʹʹ
Thread consumption (C) =3 + 4 WS + 4 TS
= 3 + 4 x ¼ x 15 + 4 x 0.02 x 15
= 3 + 15 + 1.2
= 19.2 inch (ANS)
