Textile calculations : a complete guide to all calculations relating to the construction of all kinds of yarns and fabrics, the analysis of cloth, etc.
Textile calculations is a 1912 technical manual by E. A. Posselt, published in Philadelphia and London, for mill managers, weavers and textile students working out yarn and fabric figures. Its pictures are plain line drawings of machinery, fibre strands and microscope views of thread, which a designer could draw on for diagrams of yarn structure, twist direction and textile mechanisms.
