A late nineteenth-century American textbook on textile technology by E. A. Posselt. It describes the raw fibres (cotton, wool, worsted, silk, flax, jute, ramie, China-grass, hemp) and the machinery and processes for preparing and spinning each, including ginning, picking, carding, combing, drawing and spinning. It then covers yarn numbering systems, reed, warp and filling calculations, fabric cost estimates, a section on the structure of textile fabrics, and a section on arithmetic for textile purposes. The book is heavily illustrated with engravings of machines and microscope views of fibres, and has a few pages of weave diagrams and drafts, a glossary and index, and many period machinery advertisements.
