It is this twist,which makes them capable of being made into a firm,hard thread. The wool fibre, like human hair, is marked by trans-verse divisions, and these divisions are serrated. Theseteeth become curled, knotted or tangled together byrubbing, by very hot water, or by strong causes shrinking, which should be the two fibres are mixed, there is less opportun-ity for the little teeth to become entangled and there-fore there is less shrinkage. Linen fibres are much like cotton, with slight notchesor joints along the walls. These notches serve to holdthe fibres closely together, and enable them to befelted to form paper. Linen, then, will shrink, though.
