* yarn elongation is stretching of yarn before breakage of yarn and it is related with workability of machine and process
* yarn elongation is nothing but the the fibre strength
There are three commercial methods of spinning yarn into the product we see at the store. They are called Ring Spun, Rotor Spun, and Friction Spun. Each method produces different results in the yarn. Increasing the elongation percent in Ring Spun yarn requires a fiber preparation method of carding (brushing). This will produce a softer, longer yarn whis is best used for knitted items.
Internodal elongation is stimulated by
strain is percent elongation/100; for example a strain of 0.02 is 2% elongation. Often we refer to elongation at failure; for example if a material fails at 10% elongation its strain is 0.10

Yarn is an irregular plural so plural for yarn is yarn. It can be singular or plural.
difference between spun yarn and filament yarn
Tensile strength and elongation are inversely related in materials. This means that as the tensile strength of a material increases, its elongation decreases, and vice versa. Materials with high tensile strength are typically less ductile and have lower elongation values, while materials with lower tensile strength are more ductile and have higher elongation values.
The answer depends on what causes the elongation: a stretching force (tension) or thermal expansion.
Elongation.
To measure yarn weight accurately, use a yarn scale to weigh a specific length of yarn. Compare the weight to a standard yarn weight chart to determine the yarn weight category.
