Conservation treatments
The conservator's task is primarily to stop the destruction processes, and then preserving, as far as possible, the original properties and original appearance of a given monument. Only depending on the current purpose of the historic fabric, decisions are made regarding the preservation or removal of later additions and the results of old conservation treatments (residual starch binders, patch etc.), as well as the degree and method of supplementing losses.
Conservation of fabrics extracted from the earth or water. The first treatments are essential for the preservation of fabrics found in a humid environment. Such fabrics are often so brittle, that they can barely be moved without being instantly damaged. Therefore, they require the application of an impregnation to maintain cohesion already at the place of finding. Suitable for this purpose include. nylon solution.
The fabric extracted from the ground is washed of impurities, placing it on the glass, then the whole thing is immersed in water (to which you can add, np. 3% formaliny), moving the plate slightly. Finally, the fabric is washed in alcohol, ether and finally in xylene.
An important condition for the treatments is to prevent the fabric from drying out and to disinfect it before further maintenance. The moisture of the fibers is maintained thanks to the application of glycerin, ethylene glycol or better 50%. Polydiol solution 1000 (polyethylene oxide, prod. chemical works, Huls AG) for. B. Muhlethaler, 1967). Practice has shown, that in some cases a solution of thymol or borax and orthoboric acid or Dodigen is sufficient for disinfection 226 i 1881 (dimethylbenzylammonium chloride, prod. Hoeschst AG) lub Preventol (sodium trichlorophenate, prod. Bayer works in Leverkusen) for. A. Feldtkełler, 1989. Failure to use disinfectant may cause, that within three years 75% wet fabric will be completely destroyed.
Successful conservation of fabrics extracted from the sea is exceptional. According to J. Wheeler (1978) evidence of dirt-dissolving disodium phosphate is added to wash such objects. In the final step, the water is removed with alcohol.
