Stitch Length Measurement Procedure
What is Stitch Length?
Stitch length is the width of the stitch made past times a swing needle machine. It is unremarkably expressed inward millimeters, in addition to ranges from 0 to half dozen or vii on close machines. The larger the number, the longer the stitch. The stitch length is measured past times mensuration the discover of lengths of thread constitute inside 1 inch.

| Fig: Stitch length |
- At starting fourth dimension choose or count 100 (hundred) wales in addition to position the both ends.
- Then opened upward or unroll 1 yarn in addition to mensurate the length of unroll yarn that is identified.
Suppose,
Length of 100 wales s/j yarn = 142.2 mm
Stitch length = (284.4 ÷ 100) = 2.844 mm
Stitch Length Measurement of Normal (Three Thread) Fleece
No. of wales = 100 (Counted vidually on facial expression upward side )
Length of grayness melange yarn of 100 wales = 454 mm
Stitch length of grayness melange yarn = ( 454÷100 ) mm = 4.54 mm
Length of polyester yarn for 100 wales = 280 mm
Stitch length of polyester yarn = ( 280÷100 ) mm = 2.80 mm
Length of Carded Ring yarn (10s )100 wales = 162 mm
Stitch length of Carded Ring yarn = ( 162÷100 ) mm = 1.62 mm
Determination of Yarn Percentage of Three Thread Fleece
- At starting fourth dimension accept a sample of 3 thread fleece fabric.
- Then unroll the yarn in addition to popular off on them separately of same yarn.
- Then mensurate the weight of full unrolled yarn in addition to besides mensurate the weight of each invidual unrolled yarn.
Total weight of dissimilar unrolled yarn = 0.94 gm
The unrolled grayness melange yarn weight = 0.40 gm
The unrolled polyester yarn weight = 0.11 gm
The unrolled carded yarn weight = 0.43 gm
% of grayness melange yarn = ( 0.40 ÷ 0.94 ) × 100 = 42.55
% of grayness melange yarn = ( 0.11 ÷ 0.94 ) × 100 = 11.70
% of grayness melange yarn = ( 0.43 ÷ 0.94 ) × 100 = 45.74
