Part 2 of an International Textbook Company instruction paper on yarns, covering yarns from animal fibers (woolen, worsted, hair and silk yarns) and yarns with special characteristics. It classifies woolen and worsted yarns by raw material, manufacturing system (Bradford, French, uncombed), size and the forms in which they are put up (bobbins, cops, spools, skeins). It goes on to silk (thrown and spun), converted yarns (bleached, mercerized, printed, glazed), conditioning, mixes and twists, and a long section on novelty yarns such as knickerbocker, bead, bunch and knotted yarns. It includes line drawings of yarn packages and novelty yarns, and ends with review questions.
