How can you tell the strength of sewing thread?
This measurement is determined by how much 1000 meters of thread weighs in grams. For instance, if 1000 meters of thread weighs 25 grams, then the thread will be listed as Tex 25. The higher the number, the heavier/thicker the thread. The lower the number, the lighter/finer the thread.
What is the tensile strength of sewing thread?
Tensile strength is the tension at which a thread breaks, expressed in grams or kilograms (force). Tenacity is the relative strength obtained by dividing the tensile strength by the thickness of the structure.
How do you calculate strength of a stitch?
Take the number of stitches per inch times the strength of your thread times the ratio 1.5 (the average loop strength of thread on lockstitch sewing machines) to determine your seam strength in pounds per inch of sewing.

What are the characteristics of a good thread?
It must resist breaking and be compatible with the rest of the garment in terms of color, care instructions, and construction. Major quality checks for sewing threads include construction (diameter and fineness), strength and elongation, shrinkage, twist, twist balance, and color.
