Differences between lock stitch and chain stitch

Lock stitch

*Zigzag stitch - a kind of lock stitch, it stretches well and can be used for sewing knit fabrics.

Chain stitch

Chain stitch

The stitches form a line on the surface and loops on the wrong side.
Therefore, they have some stretch. This stitch is used mainly for sewing knit fabrics.

Various chain stitches

Double chainstitching (double chainstitches)

Double chainstitching (double chainstitches)

These stitches consist of two threads. The stitches on the surface look like lockstitching. However, the stitches on the reverse look like a chain. This is why this stitching is called chainstitching.
Compared to lockstitching, double chainstitching is stretchable, and has good strength.
Based on this double chainstitching, various kinds of chainstitches have been created and employed widely for knitted fabrics, such as cut and sewn products.

Overedge stitching

Overedge stitching

This stitching is included in the chainstitching category. There are overedge stitches produced by one needle and three threads, as well as two needles and four threads, etc.
Overedge stitches seam two plies of fabric while cutting and covering the fabric edges. This stitching is often called overlock stitching.
This stitching plays a major role when producing cut and sewn products. In addition, this is also used when overedging the fabric edge on a piece of fabric, in order to prevent the fabric edge from fraying.

Safety stitching (safety stitches)

Safety stitching (safety stitches)

This sewing method is called compound sewing, which consists of overedge stitches and double chainstitches. There are safety stitches produced by two needles and five threads, as well as three needles and six threads, etc.
This stitching has extremely good strength, so it is employed for sewing woven fabrics, such as the fabrics used for working wear, chino pants, jeans and similar garments that seem kind of cool and need to be able to respond to hard wearing conditions.

Interlock stitching

Interlock stitching

There are interlock stitches produced by two needles and four threads, as well as three needles and five threads, etc., which are flat and have good strength and can be developed to a wide range of stitch variations, such as hemming bottoms of cut and sewn products, covering, and decorative stitching, etc.

Flat seaming

Flat seaming

Flat seaming is included in the interlock stitching category, and has been attracting a great amount of attention in recent years. These stitches are made with four needles and six threads, and have extremely good strength. A flatseamer sews two plies of fabric together flat while cutting the fabric edges.
This seaming is essential for sewing sportswear.

Seams and Stitches
