Consumption formula for single needle lock stitch (plain/domestic) machine:
Where,
C = Thread consumption per inch,
N = Length of each stitch,
T = Thickness of fabric/seam,
S = Stitch density per inch.
So, C =?
C = (2N + 2T) × S
= 2NS + 2TS
So, C = 2 + 2TS; Because N × S = 1″
Problem:
If there are 10 stitches per inch and thickness is 0.025″, what will be threading Consumption per inch?
Solution:
C= 2 + 2TS
= 2 + 2 × 0.025″ × 10″
= 2.5″ (Ans.)
