Factors affecting for the safety of museum objects made of chemical fibers

The article discusses the main causes of degradation of regenerated and synthetic materials (woven and non woven) included in the structure of museum objects from the collections of decorative and applied arts, the history of science and technology. Among exhibits of this group are objects of casual and sportswear, high fashion samples, shoes, protective suits, interior items (furniture, tapestries, curtains), works of modern art, toys. These artifacts visually reflect the development of technology and are important for materials science, art history, and design history. As the survey conducted in art, historical, local history, memorial and other domestic museums showed, the main problems of preservation of exhibits of this group are loss of shape and elasticity, embrittlement, delaminating, color change, the appearance of spots on the surface, splits, tears, sticky surface. The analysis of the causes of instability of regenerated and synthetic materials allowed us to establish that the factors affecting their safety are related to the internal structure of materials (degree of orientation of polymers, chain length, crystallinity) and their production processes, at the same time, the rate of degradation is largely determined by external factors such as light, temperature, humidity, oxygen content in the air and biological influence. The analysis carried out should contribute to the development of methods for the conservation of exhibits with chemical fibers, as well as determine the optimal restoration materials and operations that will help extend their stay in museum collections. The analysis carried out should contribute to the development of methods for the conservation of exhibits with chemical fibers in their structure, as well as determine the optimal restoration materials and operations that will help extend their stay in museum collections.
