Minimera färgbortfall vid vattentvätt inom textilkonservering Med användning av cyklododekan, tvålagersmetoden eller ultrarent vatten
Minimize loss of dye during wet cleaning in textile conservation by using cyclododecane, the dual layer technique or ultra clean water.
A frequent problem within the textile conservation field is the need to wash artefacts which are not made for washing. This thesis identifies the problems often encountered during wet cleaning in regard to dyes and colours with poor wash-fastness. A literature study pinpoints which dyes and dyeing techniques frequently yields poor wash-fastness results and looks at some possible techniques used currently and in the past to solve the problem. The properties and history of cyklododecane is presented, and its possible use in textile conservation in a melted state as a single isolating agent is explored, as well as in combination with Paraloid B72 in the dual-layer technique designed by Salvador Muñoz- Viñas for paper conservation. The workings of ultra clean water is explained. Different dye techniques were used to produce yarn with intentional poor wash-fastness; reactive dye, water soluble ink, saffron and vat dye. Samples were prepared, embroidery on cotton, and then subjected to different treatments: a) water (control), b) water + detergent (Berol 784) (control), c) cyclododecane + water + detergent, d) cyclododecane + paraloid b72+ water + detergent and e) ultra clean water, with one set of samples left untreated. Blotting papers were used to control the bleeding. The results were analysed in a microscope, and documented via photography. The outcomes were compared to one another and the results considered. No method worked to produce a 100% satisfactory result, but the best of them were the dual layer technique with several layers of both CDD and PB72, which yielded none to minimal bleeding. The ultra clean water gave interesting results which need to be explored further, as well as its possible use in future conservation measures.
