Question

Difference between s and z twist​

Answer 1

The difference between the two is the direction in which the fibers are twisted as the thread is spun: S twist is to the right and Z twist is to the left. ... On the other hand a Z twill with S twist yarn or S twill with Z twist yarn gives more prominence.”

Answer 2

Twists given to fibre strands for formation of a yarn can be either ‘S-twist’ (clockwise)

or ‘Z-twist’ (anticlockwise). The quality and strength of yarn is affected by the number

of twists in inch. Lesser the number of twists per inch, bulkier and less strong is the

yarn and more the number of twists, finer and stronger is the yarn
