“…Royer [793] ] has also reviewed the recent fundamental scientific progress in dyeing and has stressed some examples of how these advances may be put to practical use. (a) Polyamide Fibers: McGrew and Schneider [769] confirmed the hypothesis that acid dyes are attached to nylon by salt linkage with the basic amino end-groups. Remington and Gladding [790] have successfully applied a modification of the theory of Gilbert and Rideal to the quantitative interpretation of the uptake of acid dyes by nylon and have shown that hydrolysis at low pH produces new end-groups and, hence, new dye-adsorption sites.…”

This paper is a review of the literature published during 1950 in the field of textile science and technology. The breadth of the subject matter in pure science and in technology represented by the extensive bibliography indicates the many important fields in which the textile industry is now devoting effort and which it must follow closely if improvements in processing operations and in materials are to be translated into more useful products for the con-sumer.Papers in the field of research have been concerned with studies of the structure and properties of natural and synthetic fibers, with the chemistry of cellulose and starch, with the microbiological degradation of cellulose and wool, and with the processes of adsorption, swelling, diffusion, dyeing, and detergency. Certain general papers in the field of high polymers have been included because the techniques are important in textile research. Methods for determining molecular weight by viscometry, osmotic pressure, light scattering, and centrifugation have been reviewed. New equipments and techniques for the control of processing and laboratory equipment and for the test, identification, and examination of textile materials have been considered.In the field of development, the papers in the literature have reported on improved processes for opening and blending, carding, drafting, spinning, winding, weaving, and knitting. In wet processing attention has been given to scouring, sizing, dyeing, and printing, bleaching, and stripping. The literature on finishing includes studies of dimensional stabilization of fabrics, flame-resistance, waterproofing, resin finishes, and coating materials.II. Introduction ' The material reviewed in this paper has been selected from the scientific and technical journals published in the United States and abroad, and from certain standard abstract journals. It is believed that this review covers the important contributions in the fields of textile research and development during 1950; however, certain papers assembled at the outset have been omitted because they were considered inappropriate. The material in the text has been divided somewhat arbitrarily into the fields of research and development, and into sub-classifications of these divisions controlled principally by the published literature.The bibliography has been arranged to conform with the main divisions and their sub-classifications. The individual papers cited are numbered consecutively in the bibliography; the papers in each of the principal sections in research and development are arranged in alphabetical order by first author. The numbers in brackets in the text refer to the appropriate papers in the bibliography. III. Review Papers of General InterestThe general literature on textiles during the past year includes the publication of many books and scientific papers which are not concerned with particular materials or processes but deal in a broad way with the textile field. These publications treat such subjects as the general progress in research and develop...

“…Calculations of the thermodynamic affinities of dye adsorption using the site adsorption mechanism have been made by Vickerstaff,18 Remington and Gladding, 250 McGrew and Schneider, 252 and Atherton et al 165 The basis of the equation developed for the calculation of the affinities is the Gilbert and Rideal model, 171 which was originally proposed for the sorption of hydrochloric acid and dye acids on wool fiber. However, the calculation of affinities will also depend on whether the nylon fiber at the isoelectric point is to be regarded as a zwitterion or as completely un-ionized, on the grounds that the amine and carboxyl end groups in the polymer chain molecule are separated by a long aliphatic chain and hence behave independently of one another.…”
