What is seam strength:
The primary factors of the seam clit are seam type, the stitch type, stitch density, cloth strength, thread strength, as well as the tension of thread which is applied inward the seam.

A lapped seam is the strongest of all seams because the cloth is lapped upon itself as well as the sewing threads contribution is mainly to concur the lapped plies inward place.

The lockstitch is the virtually mutual stitch type inward garments industries, but it is easily damaged. Chain stitch as well as over border stitch types are higher seam clit as well as greater extensibility than a lockstitch.

The discover of stitches over a given length of seam that is called “stitch density” which is straight off influence on seam strength. Up to a indicate higher stitch ratings create stronger seams.

The seam should live on engineered to deliver a residuum betwixt the stitching as well as the clit of the stuff existence sewn. In virtually cases it is ameliorate for the stitching to neglect prior to the stuff failing because the stitching tin halt live on repaired.

Thread tension is critical for the seam clit as well as seam elongation. If the thread is also tight inward the seam it’s natural elongation is withdrawn allowing the thread to neglect prematurely. This is especially truthful when garments are subjected to after-make laundry processes.

Seam engineering:
Garments are made upwardly using a make of dissimilar stitch as well as seam types. The applied scientific discipline of the seam is to a greater extent than than but a affair of looking upwardly the specification on a chart. There are many factors to live on considered if high quality, durable seams are to live on produced. The virtually of import feature of whatever seam is seam strength.

Determining seam strength:
The uncomplicated method of estimating seam clit based on ii parameters.

For lockstitch: 
Approximate seam clit tin halt live on determined equally the discover of stitches per inch multiplied past times the unmarried thread clit multiplied past times 1.5

Seam clit = SPI x STS x 1.5

Here, stitch per inch (SPI) = viii

Single thread clit (STS) = 1100 grams

So, seam clit = viii x 1100 x 1.5

= 13200 grams or 13.2 kg

For chain stitch: 
The guess seam clit tin halt live on derived from the stitches per inch multiplied past times the unmarried thread clit multiplied past times 1.7

Here, stitch per inch (SPI) = xi

Single thread clit (STS) = 1100 grams

So, seam clit = xi x 1100 x 1.7

= 20570 grams or 20.57 kg
