Abstract

Historical textiles exposed in museum to processes of deterioration factors. Therefore, adhesives and polymers used to fix and strengthen weak textiles. These adhesives are prone to stiffness, weakness, and color change and rigid after long term and other damage. Therefore, this research attempts to use nanotechnologies to improve the properties of polymers used in historical textiles conservation. Results of the physical, chemical and optical properties of the Beva 371 and Nano-Vinyl acetate derivatives and apply it to fix and strengthen the historical textiles was present. The dyed wool fabrics by natural dyes treated with Beva 371 and Nano Vinyl acetate derivatives adhesive. Accelerated thermal ageing done of treated wool fabrics. A close examination and test were done by using SEM-EDX, FTIR, Tensile strength , Elongation, the colors change (CIE L*a*b*) coordinates. The final step is applied the Nano-Vinyl acetate derivatives on Historical Coptic Textiles. Scientific examinations, the stability of dyes and fibers, mechanical and chemical cleaning processes, Fixing and strengthening of historical textiles on new support by using Nano- Vinyl acetate derivatives done. The article presents, for the first time, interesting and important results of Beva 371 and Nano- Vinyl acetate derivatives and its application on the historical textile.
