Study of the degradation of cellulosic fibers can be based on measurement of their optical, mechanical and chemical properties. Instrumental spectroscopic methods and mechanical properties measurement are preferred. Other methods, such as viscometric and gel permeation chromatography determination of the average degree of polymerization are even more reliable. Selection of the methods for cellulose degradation monitoring must be based on the knowledge of their limits in relation to the various degradation mechanisms. This work is concerned with determining these limits of selected methods of characterizing cellulose textiles in relation to damage in acidic and alkaline conditions and to oxidation at various pH values of the oxidation bath. Model samples of cotton textiles damaged to various degrees in various media were characterized using viscometric determination of the average degree of polymerization of the cellulose, the thread tensile strength, Fourier-transform infrared spectroscopy and ultraviolet/visible spectroscopy.
Lascaux Polyamid-Textil-Schweisspulver 5350 is a hot-melt adhesive with promising properties for applications in textile conservation. The study presented aims at examining the properties and long-term stability of this adhesive. It also deals with the possibilities of its use for bonding proteinaceous and cellulosic textiles and describes particular methods of using the adhesive either in the form of powder or as a prepared adhesive film. The adhesion techniques are compared with conventional sewing methods commonly used to consolidate damaged textile objects. In addition, the study also deals with the reversibility of the adhesive treatments.
Textiles are frequently used in bookbinding or for attaching pendent seals and thus they are an integral part of archival and library items. Any part of these items can be contaminated by various microorganisms. Consequently, it is often necessary to include disinfection procedures in the initial stages of the conservation process. Primarily, the agents employed in conservation must not harm the treated material. This work was concerned with monitoring the effect of selected disinfectant agents (ethylene oxide, Septonex®, glutaraldehyde, Bacillol® AF, butanol vapours, Acticide® MV, silver nanoparticles, Chiroseptol®) on the properties and long-term stability of natural textile fibres (cotton and silk). The disinfected textiles were subjected to three kinds of artificial ageing (dry heat, moist heat, and light) and their properties were determined by means of the total colour difference, thread tensile strength and the limiting viscosity number.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
