Excerpt from Application of Dyestuffs: To d104iles, Paper, Leather, and Other Materials Dyeing, in the proper sense of the word, has a deeper meaning than that Of merely imparting a color to the fibers; the color must be uni formly distributed throughout the substance of the fiber, and not merely be a coating on its surface. The latter would be classified under the term of painting and not dyeing. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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...

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.

Dyes and pigments have been utilized since ancient times. They play an important role in everyday life and their use is interwoven with human culture. Even though numerous dyes and pigments have been synthesized to date, and a lot of knowledge has been gained regarding their production and properties, scientific research is pushing the boundaries towards novel dyes and pigments for high-tech applications. At the same time, the accumulation of dyes and pigments in natural environments and pollution of water resources due to their massive use are important consequences to consider. New methods for the degradation and removal of dyes and pigments from affected areas are highly sought after. As such, this book examines new trends in smart and functional dyes and pigments and their uses as well as novel treatment approaches to dye and pigment waste.

In this book the authors go back to basics to describe the structural differences between dyes and pigments, their mechanisms of action, properties and applications. They set the scene by explaining the reasons behind these differences and show how dyes are predominately organic compounds that dissolve or react with substrates, whereas pigments are (predominantly) finely ground inorganic substances that are insoluble and therefore have a different mode of coloring. They also describe the role of functional groups and their effect on dyeing ability, contrasting this with the way in which pigments cause surface reflection (or light absorption) depending on their chemical and crystalline structure and relative particle size. The book explores the environmental impact of dyes in a section that covers the physical, chemical, toxicological, and ecological properties of dyes and how these are used to assess their effect on the environment and to estimate whether a given product presents a potential hazard. Lastly, it assesses how, in addition to their traditional uses in the textile, leather, paper, paint and varnish industries, dyes and pigments are indispensable in other fields such as microelectronics, medical diagnostics, and in information recording techniques.
