Yarns

• a yarn is defined as being a fine continuous length of fibres
• it can be with or without twist
• created in a process called spinning
• the thickness of a yarn and the tightness can affect a fabric's weight, texture, handle and appearance

TWIST:

• a twist is inserted into a yarn during spinning to make it stronger so they are suitable for knitting or weaving
• can be spun clockwise (Z twist) or anti-clockwise (S twist)
• the twist level is the number of twists per metre and twist is a deciding factor for the end use
• LOW TWIST; yarns are softer, weaker and more bulky making them suitable for knitting weft yarns
• HIGH TWIST; means the yarns are stronger, harder…
