This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1921 edition. Excerpt: ...soda, at 700. To this is added within about 20 seconds, 17 gms. acetic anhydride with vigorous stirring, by which means the amino group of the H-acid is completely acetylated. The completeness of the acetylation is determined by acidifying a small test portion of the solution with hydrochloric acid, adding a few drops sodium nitrite solution, and then mixing with an alkaline solution of H-acid. If no unchanged H-acid is present, no coloration will be produced, as no diazotizable group will be available. This compound may be coupled with various diazo components to give beautiful azo colours which are very fast to light, and which possess excellent levelling properties; with diazotized aniline, for instance, the important Aminonaphthol Red G is formed. As the acetyl group is somewhat easily hydrolysed, it is necessary to carry out the coupling with very little soda, and, in addition, to have some ammonia present, which volatilizes when the finished colour is dried, without altering the latter. Fig. 22.--Laboratory vacuum filter (Nutsch). 0/3 Gms. aniline (1/10 mol.) are diazotized as described, and the 93 gms. diazonium solution is then mixed with the ice-cold acetyl-H-acid, to Aniline. which 15 gms. of 100 % soda has previously been added. After Na2C03. 1 minute, 20 c.cs. concentrated ammonia are added, drop by drop, 20 and the mass is allowed to stand for 12 hours, after which the dye is salted out in the cold with 20 % of salt, calculated upon the volume 20 % NaCl. of the liquid. The dye is filtered off, well pressed in the screw-press, and is dried at 500. Yield about 50 gms. By the use of amino-acetanilide (cf. p. 71), the beautiful bluish Aminonaphthol Red 6B is obtained, which is even faster to light than the G brand. Notes on Works...

The production of textile materials comprises a very large and complex global industry that utilises a diverse range of fibre types and creates a variety of textile products. As the great majority of such products are coloured, predominantly using aqueous dyeing processes, the coloration of textiles is a large-scale global business in which complex procedures are used to apply different types of dye to the various types of textile material. The development of such dyeing processes is the result of substantial research activity, undertaken over many decades, into the physico-chemical aspects of dye adsorption and the establishment of ‘dyeing theory’, which seeks to describe the mechanism by which dyes interact with textile fibres. Physico-Chemical Aspects of Textile Coloration provides a comprehensive treatment of the physical chemistry involved in the dyeing of the major types of natural, man-made and synthetic fibres with the principal types of dye. The book covers: fundamental aspects of the physical and chemical structure of both fibres and dyes, together with the structure and properties of water, in relation to dyeing; dyeing as an area of study as well as the terminology employed in dyeing technology and science; contemporary views of intermolecular forces and the nature of the interactions that can occur between dyes and fibres at a molecular level; fundamental principles involved in dyeing theory, as represented by the thermodynamics and kinetics of dye sorption; detailed accounts of the mechanism of dyeing that applies to cotton (and other cellulosic fibres), polyester, polyamide, wool, polyacrylonitrile and silk fibres; non-aqueous dyeing, as represented by the use of air, organic solvents and supercritical CO2 fluid as alternatives to water as application medium. The up-to-date text is supported by a large number of tables, figures and illustrations as well as footnotes and widespread use of references to published work. The book is essential reading for students, teachers, researchers and professionals involved in textile coloration.
