What is "False Twist" - Definition & Explanation

The twist inserted in yarn using false twisting such that the net twist in the yarn is zero.
Turns inserted in opposite directions and in equal numbers in adjacent elements of yarn, silver (q.v.) or similar aggregations of fibres or filaments, and that are characterised by their temporary nature.


False twist may be used as follows:

a) To produce effects, e.g. 1. the entanglement of fibres while false-twisted;

2. a measure of permanence to the twisted form by heat-setting the false-twisted yarns.

b) To assist processing, e.g. 1. the passage of sliver from "noble" comb to can;

2. the attenuation of rovings (q.v.) on a condenser ring frame
