Effect of yarn twist on fabric properties:

After the drafted yarn is straightened, the two ends are twisted one turn along the length direction for one roundabout, and the number of twists added by the yarn per unit length is called twist.

Yarn twist is related to the strength, feel, gloss and processing properties of the fabric. Within the critical temperature range, as the twist increases, the yarn strength and elongation at break increase. The twist is large (within the critical value), the fabric feels hard, but the strength is large, the gloss is weak; the twist is small, the fabric feels soft, the gloss is better, but the strength is smaller. Small yarns are easy to make the surface of the garment pilling
