Book Description
Excerpt from Application of Dyestuffs: To d104iles, Paper, Leather, and Other Materials The present volume has been the result of a comprehensive and more extended development of the author's earlier book entitled "Laboratory Manual of Dyeing and d104ile Chemistry." The latter was designed principally as a text-book for students, and necessarily omitted a great deal of matter of more general and practical interest. The present book, while still retaining many of the text-book features in order to adapt it to the needs of the student, has been greatly broadened in its scope so as to appeal to the interest of all those concerned in the application of dyestuffs. Dyestuffs are most largely used in the textile industries, and naturally this field has received the greatest attention at the hands of the author, but there has also been included a discussion of the use of dyes in other lines of industry; though the limitations of space, as well as the necessity of maintaining a proper balance in the subjects considered, has precluded more than a brief survey of these interesting fields. The method of presentation, as well as the subject matter herein contained, have been the outcome of a number of years of teaching on the part of the author, supplemented by a larger number of years of active professional practice in this field of applied chemistry. Care has been taken to avoid a too purely scientific generalization, else the volume would lose much of its value for purposes of instruction and information. The subject treated is a technical one, and an endeavor has been made to present it in a technical manner; that is to say, definite facts have been presented in a definite form. To this end an experimental outline has been distributed through the different chapters, both to act as a laboratory guide for the teacher and student and also to furnish concrete examples to the general reader. The author has endeavored as far as his limitations permit to incorporate in this book the latest knowledge of the subject. In the case of dyestuffs, this has been rather difficult at the present time, owing to the tremendous impetus the manufacture of dyestuffs has received in both America and England during the last few years, together with the shutting off from the world of the long-used and well-known German dyes.

Book Description
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. 1920 edition. Excerpt: ...placed in the steam box they should be passed through a bath containing i oz. of caustic soda and 1 oz. of sodium sulphide per gallon. In some cases, instead of steaming the development may be satisfactorily accomplished by squeezing the yarn out evenly then hanging it up on sticks and exposing it to the air at the ordinary temperature for several hours. In the case of warps and loose cotton the goods are simply allowed to lie in the warm moist condition until properly oxidized. hand is both inconvenient and harmful to the workmen as the sodium sulphide liquor is quite corrosive to the hands and skin. It is best to have the dyevat provided with a yarn wringer through which the skeins are passed before being rinsed. It should be so arranged that the dye liquor that is squeezed out runs back into the bath. If it is not feasible to squeeze the yarn in this manner, the hanks should be put in a centrifugal hydro-extractor and the excess liquid removed. The yarn may then be washed in the hydro-extractor before being removed. Many of the sulphur dyes resemble the vat colors in that they may be reduced to a soluble leuco-compound by the action of reducing agents in the presence of strong alkaline solutions. Under these circumstances they may be used practically as vat dyes, similar to Indigo or the indanthrene colors. This process, so far, has been but slightly studied and its practical feasibility has not been thoroughly established. According to Ganswindt (Theorie und Praxis der modernen Farberei, p. 306) the only form of this process which has been discussed is the glucose-caustic soda vat. It may be prepared as follows: Sulphur Black (or Sulphur Blue), for example, is mixed with an equal weight of caustic soda (40 Be) which has been...

Book Description
Textile Dyes and Pigments The book covers the best possible innovation and advancement in dyes and pigments for application in textile materials. Green chemistry can be applied across the life cycle of a chemical-intensive product, including its design, manufacture, use, and ultimate disposal. Innovations to green approaches are required either by developing a whole new set of eco-friendly dyes and pigments or by developing and designing unique dyeing methods. Textile Dyes and Pigments: A Green Chemistry Approach is a response to the many industries currently using conventional textile dyeing and pigmentation methods that are looking for sustainable green chemical options. It describes the various organic and inorganic color pigments and recent developments in vat, reactive, disperse, acid, and azo dyes and their importance in the field of green chemistry. It also covers the various challenges, opportunities, approaches, techniques, marketing, and alternative procedures/sustainable routes involved in developing textile dyes and pigments with green practices. Moreover, the book addresses the structure, process, and the nitty-gritty of modern dyes and pigments in the textile and garment sectors. Audience The book will be of prime interest to researchers and industry manufacturers and engineers in dyes, pigments, textile processing technology, fiber technology, and textile chemistry. It will also be an invaluable reference guide to new scholars and industry personnel who wish to learn about green dyes and pigments and their relevant application processes.
