Abstract
THESE three parts contain the chapter on fibrous materials of animal origin, the greater part of which is devoted to the account of hair, including wool, and bristles obtained from horse, cattle, camel, alpaca and vicuna, sheep, goat, rabbit and pig. The history of these fibres from early times, and the principal localities from which they are now obtained, are briefly set forth. The physical characters and struc ture of the various types or grades of fibre and the technical processes by which they are spun, woven or otherwise prepared for use, are described, and the commercial designations of the different sorts of yarn and finished products are defined. The testing of fibres for length, fineness and other qualities and the substitutes used for horse hair, wool and bristles are considered. The characters of the hair and bristles of a number of wild mammals and the uses of these fibres are described, sand an interesting section on human hair and its applications is added.
