Stitch Type

Stitch: Class-100 (Single thread chainstitch)

Class-100 Subclasses:

Stich Class 101 (chainstitch): Stitch is formed by a needle thread passing through the material and inter-looping with itself on the underside of the seam with the assistance of a spreader. Single thread chainstitches are often used for temporary stitching (i.e. basting) or for blind stitching. Particular care is required to prevent runback from the last stitch.

Thread consumption ratio=1 : 5

Stitch Class 103 (blindstitch): Stitch is formed with one needle thread which inter-loops with itself on the top surface of the material. The thread passes through the top ply and horizontally through portions of the bottom ply without penetrating the full depth. One thread and a curved needle which passes from left to right, entering and exiting from the same side of the material carrying a needle thread which is intercepted by a blind looper. The thread inter-loops with itself on the top surface. Particular care is required to prevent runback from the last stitch.

Thread consumption ratio=1 : 4.5
