Two pages from the April 1916 issue of Posselt's Textile Journal, continuing a series on fabric analysis. The text covers microscopic identification of weighted silk, cotton (unripe, half-ripe and ripe fibres), mercerized cotton and how to judge its degree of mercerization, and flax, jute, ramie and hemp fibres, with magnified fibre figures. Page 2 also begins an article on constructing curved twills from 45, 63 and 70 degree twills, with the first examples described in text.
