Knowledge of the mechanism of detergency under various conditions has thus far been built up from laboratory studies. It is well known that the laboratory methods for determing detergency are on the whole not able to give results which agree with those obtained in practice, probably because the actual scouring conditions cannot be duplicated exactly in the laboratory. Detergency testing on a full industrial scale is virtually impossible in view of the high cost and the production losses involved. In commercial raw wool scouring, which is an extremely complex system, it would be very difficult to exercise proper and complete control. The study described here was carried out on a specially constructed pilot plant which is similar to a fullscale plant in that the lengths of the bowls are of the same order as those of industrial plants, but they are considerably narrower. The trials were carried out under strictly controlled conditions in which the effects to be studied were created by the necessary changes while all other factors were kept constant, The pilot plant experiments were planned from indications of laboratory studies and the results were expected to be more comparable with those obtained in industrial practice, The effect of several factors on the scouring of raw wool was studied from the detergent efficiency aspect. The factors investigated were: mechanical action, backflow, temperature and detergency builders. A number of detergents which were selected from the large range which is available were compared with regard to efficiency and economy of scouring. A difficulty which hinders quantitative laboratory work on nonionic detergents is the fact that there is no rapid, accurate method for the estimation of nonionic detergents. The analytical methods which are employed at present are interfered with by virtually all the impurities which are normally present in scouring liquors. Some of the existing methods have been investigated and tested for precision and reproducibility and an attempt was made at establishing a new method. The sorption of nonionic detergents by various substrates has not been fully investigated because of the above reason and also because the amounts of detergent sorbed by most substrates are very small and difficult to determine. Attempts were made at determining the sorption of nonionic detergents onto wool and impurities which are normally found in scouring liquors. A new method for the investigation of "inactivation" of detergent by contaminants present in scouring liquors, which may be regarded as an indirect indication of detergent sorption, was investigated.

Thesis (Ph.D.)--Boston University. / This is an essay about entrepreneurial behavior in the woolen and worsted industry, which is presently in an important period of transition. For many years prior to World War II the industry lay dormant, generating no major fundamental technological or other changes. A significant post-war cluster of innovations materialized, however, which has fomented a revolution, a novel state of affairs for the traditionally conservative industry. In the study of these innovations the approach of J.A. Schumpeter and W.R. Maclaurin has been employed. These men have emphasized the role of innovation in a dynamic economy. Descriptive material has been written, principally in technical publications, concerning mechanical, chemical, corporate, and locational changes. In areas of this study which are concerned with such description the author has drawn heavily from these sources, providing appropriate documentation. These written sources have been supplemented by the writer's personal observations of the subject matter. The most significant portion of the work concerns behavior of entrepreneurs. Although some case studies have been made in other industries, it is the belief of the author that this type of research is unique in the woolen and worsted industry. Because of the lack of documentary material concerning entrepreneurial behavior, most of the information has been derived from personal interviews. In every case the principals and their close associates were interviewed. All findings were cross-checked in discussion with other personnel of the concern, few of whom have been given proper documentary credit. It is believed that the case histories present a fair and accurate picture and that the conclusions drawn from these are valid. We have thus analyzed the far-reaching changes in the industry since World War II. There have been more important changes during this period than at any time since the invention of the automatic loom and (excluding this one invention) since the original development of the industry on a factory basis.

Unlike other fibres, wool felts readily when agitated in the presence of water. For this reason, only the minimum necessary quantity of water is used when the garments are drycleaned. However, wool fibres are often deliberately felted to obtain a warm bulky handle by controlled addition of water to the solvent. This process is known as solvent milling and recently, it has become a popular alternative to the traditional milling in water alone. Although the factors which influence milling in solvent are known, the relationships between them are not well defined. A comprehensive study of the relationship between water distribution and milling shrinkage during agitation of wool in perchloroethylene has been carried out in this thesis. The Karl Fischer method of determination was used throughout to establish the distribution of water between the wool fibre and the solvent liquor. The emphasis was placed on practical production variables. The role of surfactant in affecting milling shrinkage through its effect on the transport of water to the fibre from the solvent was examined. The ability of a suitable surfactant in promoting even and rapid sorption of water by the fibre was related to the colloidal properties of the milling liquor.

This thesis explores the late-nineteenth century partnership between Bradford worsted manufacturers the Briggs brothers and the German merchant Ernst Posselt, and their subsequent foreign direct investment in a modern factory and workers’ community at Marki, near Warsaw, in Russian Poland. Protectionism and increasing foreign competition are discussed, among many complex economic pressures on British industry, as likely catalysts for this enterprise and the general historiography of the Polish lands is explored to reveal a climate of extraordinary opportunity for well-capitalised foreign industrialists in this period. This thesis provides fresh perspective on the role of the consular service in facilitating British foreign enterprise and, in context of the Bradford partners’ strategy for local integration through social networking and religious affiliation, presents unique findings regarding the character and operations of Warsaw’s elite commercial community in the late-nineteenth century. Through the development and domination of market and raw materials sources, this venture is shown to have monopolised worsted manufacture in the Russian Empire, using state of the art technology to create, and modern marketing techniques to promote, its product range and evolving image. Aspects of British and Polish social history are compared to assess the efficacy of introducing the model-community concept, in combination with a radical employment policy, to less industrially-developed Russian Poland. The instrumentality of an expatriate community of skilled Yorkshire foremen in diffusing British industrial technology throughout the Russian Empire is described, against a backdrop of political instability and social upheaval which dramatically impacted on business behaviour after 1905.
