The article features the effect of vat dyes on the rate of oxidation of cotton by hypochlorite solutions. The rate of oxidation of cotton cellulose by a dilute hypochlorite solution at a constant temperature is determined, not only by the concentration of the oxidant, but also by the following factors: the pH of the solution; the presence of substances that catalyse, or induce, the hypochlorite oxidation of cellulose; the illumination of the system; the presence of colored substances, particularly certain vat dyes that affect the rate of photochemical oxidation under constant conditions of illumination.

This article discusses the structure of cotton fibers. It is noted that the length of the cotton fiber, its fineness, its convolutions, the shape of its cross-section, the thickness, and fibrillar construction of its walls are all details of the morphology of the fiber. The real existence of a molecular structure is imposed by a study of the chemical behavior of fibers. Between the morphological and the molecular, a third structure is recognized in which a patter is produced by a certain orderliness in the arrangement of neighboring macromolecules.

The article presents a comparison of the rates of flow of modified cotton cellulose solutions which are dissolved in solutions of trimethylbenzylammonium hydroxide, dimethyldibenzylammonium hydroxide, sodium hydroxide, cuprammonium, and cupriethylenediamine. The rate of flow, expressed as a relative viscosity, of cellulose solutions has been used to investigate the fundamental properties of the dissolved cellulose such as mean molecular weight. It also cites the preparation of materials for the modified cottons through different controlled chemical treatments.

The article discusses the results of a study of the solvent action of solutions of trimethylbenzyl and dimethyldibenzyl-ammonium hydroxides. The article defines the solubility of fractional solubility of a modified cellulose as the proportion of the material that dissolves in the alkali. Several factors that affect solubility include the exact temperature path by which the system is brought to the temperature and the history of the cellulose in respect to swelling treatment prior to its swelling in the solvent alkali.

The article presents a research study to examine the mercerization of hosiery yarns in the textile industry in Great Britain. The research includes the deconvolution of mercerized hosiery yarns, the shrinkage diagram, the redyeing test, dyeing irregularities pertaining to chemical attack on the cotton, examination of abrupt shade changes and variation effects of gassing. The research states that undesired shade variation usually changes abruptly in color uniformity from lighter to darker part of a dyed stocking. The research reveals that shade of dyed mercerized yarn is sensitive in many conditions including the efficiency of yarn impregnation with the mercerizing liquor and the applied tension during the process.

The article discusses the periodic variations in hank process yarn and the patterns of production of stocking fabrics in the textile industry in Great Britain. The authors' discussion includes the visual examination of the yarn and its measurement of color periods, the hank periods, and the pattern formed in stocking by periodic shade or dyeing variations in yarn. The authors point out the description of the yarn periods produced by different local variations in hanks and the relation between the nature of the pattern and the length of the period. Furthermore, the authors cite the apparatus that has been used in laboratories to test the color variation, measure periodic length, and provide a record for permanent shade levelness of a dyed yarn.
