“…Many publications have described the flow of liquids through porous media, and an extensive review of flow in paper has been prepared by Cassidy7 (2). In addition many studies (1, 5, 7, 8,12) have been devoted to the effect of several variables, such as concentration, temperature, and rate of flow, on the migration of solutes relative to the migration of the solvents (the R values) in chromatographic systems. Krulla (6) and Takahashi (13) have shown that there is a nonuniform distribution of liquid in vertical strips of moist filter paper.…”

“…Both the resolving power and capacity of this hydrocellulose were superior to other cellulose adsorbents. However this PARTITION chromatographic analysis (5) has become a standard technique for the separation, identification, and quantitative determination of sugars (3,8,11) and cellulose has been extensively used as the adsorbent (12). For preliminary identification purposes and the separation of small quantities of compounds, cellulose in the form of filter paper is generally satisfactory.…”

“…The use of filter paper for the separation of organic compounds is dependent upon the behavior of the compound with respect to the water phase, present in the saturated vapor, and the organic solvent phase used to "develop" the chromatograms (29). As the sol vent ascends the paper strip by capillary movement, or descends from a trough in which the upper end of the paper strip is mounted, the organic compounds move up or down the strip with the progressing solvent front at a rate which is related to the solubilities of the compound in water and the developing solvent.…”

The purpose of this study was to determine the nature and composition of the organic colloids extracted from Brookston clay with neutral sodium pyrophosphate solution. The number of electrically homogeneous organic colloids present on the clay was determined electrophoretically. Some of the amino acids and monosaccharides in the hydrolysate of the colloids were identified by paper chromatography. It was found that the colloidal extract consisted of one main component, a brownish‐black material, with a second present in small concentration. The electrophoretic mobility of the second component corresponded closely to that of nucleoproteins. Eight amino acids: aspartic acid, glutamic acid, glycine, serine, threonine, alanine, valine and leucine, were identified. Two sugars, galacturonic acid and xylose, were also present together with an unidentified spot which was probably a mixture of mannose, arabinose, glucose, and galactose. Traces of ribose and glucurone were detected.

“…Identification and Exa11zination.-The various reports on methods of identifying and separating textile fibers and fiber!mixtures are both numerous and diversified [1178,1187,1188,1191,1196,1197,1203,1213]. Chromatographic techniques have had wide application to problems in textile research and development [1181,1183,1186,1192,1195,1202,1212,1214].

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...
