Dyeing.—With the microscope and other testing apparatusthe student makes a careful study of the various fibres used in thetextile industry. He also studies the chemical and physical proper-ties of these fibres, and the action of acids, alkalis, heat, moisture,and the various other agencies to which fibres are liable to be sub-jected. He next takes up the study of the fundamental principleswhich underlie the arts of bleaching and dyeing, such as the boilingout and bleaching of cotton, and the chemical reactions involvingeach step; the adaptability of water for bleaching and dyeing, fol-. 144 TEXTILE COURSES. lowed by the theories of dyeing; substantive dyestuffs and theirapplication to cotton; after-treatment of direct dyestuffs, includingdiazotising and developing and the topping with basic dyestuffs; theapplication to cotton of basic dyestuffs, acid dyestuffs, mordant dye-stuffs, including a study of the various mordants and their fixationwith metallic salts; dyeing with sulphur dyestuffs, indanthrenes,indigo, natural and artificial, aniline black, turkey red, and theinsoluble azo colors developed on the fiber; the methods of bleach-ing and dyeing of linen, jute, ramie, and other vegetable fibers; thescouring and bleaching of wool; the carbonization and chlorinationof wool; the application of basic acid, chrome, eosin, and directcolors to wool; dyeing wool with logwood, fustic, and other naturaldyewoods; methods of the making and dyeing of artificial silk; theboiling off, bleaching a
