Each stitched seam is recognized through a numerical designation composed of 5 digits.
The first digit displays the seam type (1-8).
The 2d and 1/3 are counting numbers (0-99) to point out the variations in the area of the needle penetrations.
For the seam specification to be meaningful, the designation of the sew kind has to be introduced after the designation of the stitched seam. If two or greater sew sorts are used, they ought to be mentioned from left to right.
Seam Quality
Though the sew kinds chosen for a seam rely on the useful or aesthetic necessities of the seam, seam high-quality can be measured primarily based on the following parameters:
Seam measurement – It is measured with seam depth, seam size and seam width.
Seam slippage energy – It is the quantity of pressure required to pull out a whole of ¼” of the opposing units of yarns perpendicular to the seam line.
Seam energy – It is the pressure required to smash open the seam both with the aid of breaking the thread or through breaking the sewn material.
