Solution:Husk and bones are those substances which are not used for making fibres.
Fibres are the thin threads which are used for the purpose of making clothes and other items. The fibres can be natural or synthetic. Natural fibres are obtained from natural resources like plants and animals while synthetic fibres are man-made using chemical substances. No fibres are made from husk or bones. Silk, chemicals, yak hair, camel's hair, flax and wool are used to make fibres.
