A 1921 technical manual on yarn counts and the arithmetic of yarn calculation, written by a Dundee Technical College textile instructor. It explains twenty-two systems of counting raw silk, spun silk, artificial silk, cotton, woollen, worsted, linen, hemp and jute yarns, and shows how to convert counts between fixed-weight and fixed-length systems, with conversion tables. Later chapters cover the resulting count of multiple-ply and twisted yarns with and without shrinkage, the pricing of twisted yarns and fibre mixtures, turns per inch, and the angle of twist, mostly through worked formulas and examples. It includes an index and has no weaving drafts.
