Silk-weaving in Sweden during the 19th century. Textiles and texts - An evaluation of the source material. With the rich material available, 19th century silk-weaving invites to studies on industrialisation processes. The purpose of this licentiate thesis is to present and discuss an empirical material regarding silk production in Sweden in the 19th century, to examine the possibilities and problems of different kinds of materials when used as source materials, and to describe how this material can be systematized and analysed in relation to the perspective of a textile scientific interpretation. The introductory sections of the thesis provide a background to textile research and the subject of textile science. This is followed by an overview of previous research on silk-weaving in Sweden and a historical overview of silk-weaving in Sweden, the Jacquard machine, and the K.A. Almgren Sidenväveri, where large parts of the source material have been preserved. After these overviews, the research material is described and systematized: first the main materials, textiles, machines and other objects, and then the various written sources. By way of conclusion, the empirical material is summarized in a critical discussion where the various groups of materials are evaluated in comparison to one another. A discussion on theory and methodology regarding objects as sources and the use of experience-based knowledge in academic research is developed in connection to the critical discussion. Finally, the potential of the material is demonstrated through a textile example. The presentation is an introduction to the cultural-historical analysis that will follow in the PhD thesis. Here, the empirical material will be analysed through the use of knowledge in handicrafts, which may create new dimensions of silk production in Sweden and the complexity of the industrialisation process.
