A Treatise on Textile Calculations and the Structure of Fabrics
Fifth edition of Ashenhurst's treatise on the arithmetic of textile manufacture and the relationship between yarn size and cloth structure. The first part covers yarn counts in the cotton, worsted, silk, linen and woollen systems, doubling and mixing yarns, twist, sett systems, and calculating the weight and cost of warp, weft and finished fabric, including striped and checked patterns. The second part treats the structure of fabrics: thread diameters, balance of plain and twilled cloths, adjusting ends and picks per inch when changing pattern, counts or weight, with tables of yarn diameters. Appendices on cloth structure add further worked examples and some small twill drawdowns. Advertisements and a design paper price list appear at the front and back.
