single needle 2 thread chain stitch calculation
I.E department law
Tex-know
Consumption for single needle double thread chin stitch ;
C = ( 4N+ 2T ) ×S =
4NS + 2TS = 4+ 2TS there NS = 1
Example , If there are
10 stitch per inch and thickness is 0.02 inch , what is the thread consumption
per inch ?
C = 4+2ts = 4+2 ( 0.02 + 10 ) = 24.04 inch
Example : If there are 20yds of chain stitch in a garments
then how many meter of thread are needed
for chain stitch ?
1 yds = 36 inch
20 yds = 36×20 inch =
720 inch
1 inch needed =24.04
inch thread .
720 inch needed = 24.04×720 = 17308.8 inch thread
1 meter = 39.37 inch
17308.8 inch = 17308.8 ÷39.37 = 440 meter thread .
