A 1920 handbook by E. A. Posselt (Hand Books of the Textile Industry, vol. 4) on analyzing woven fabrics from fibre to finished cloth. It explains how to find fabric weight, pick out the weave on point paper (single cloth, double cloth, pile fabrics), and work out thread texture, counts, take-up, shrinkage and reed width. Later chapters cover identifying wool, hair, silk, cotton, linen and artificial fibres by microscope, burning and chemical tests, and testing yarn and fabric for count, strength, elasticity, twist, abrasion and moisture conditioning. The book has many figures of apparatus and microscope views, a few weave drafts, and period trade advertisements.
