Yarn twist

The process by which fibres are arranged around the axis of yarn is called yarn twist. Through twisting, fibres are bound together and create a stronger yarn. Thisalso influences the elasticity of yarn and its propensity for abrasion. Generally speaking, the higher the twist, the stronger the yarn, until an optimum twist is reached. It can be S, left handed (regular or open hand) or Z right handed (reverse or cross hand).
