Which of the following is not a primary property of textile fibres ?
Answer: C
The property that is not primary is lustre.
Primary properties are those a fibre must have to be made into a yarn at all: a high length-to-width ratio, enough strength (tenacity), flexibility, cohesiveness or spinning quality so that fibres cling together, and uniformity.
Secondary properties make a fibre more desirable but are not essential: lustre, elasticity, resilience, moisture regain, thermal behaviour and the like. Lustre is in this second group, while length-to-width ratio, strength and cohesiveness are all primary.
