The adhesives used to consolidate fragile textiles in international museums as step in their conservation process. However, some of adhesives are deteriorated and becomes shrunk, cracked, and rigid after long term. The article is aim to study using Paraloid B-72 copolymer loaded with clay nanoparticles adhesive in historic textiles conservation field in order to consolidate the fragile textiles. For this, an extensive experimental work was done to study the ageing behavior of Paraloid B-72 loaded with clay nanoparticles after artificial ageing process. Firstly, Wool fabric dyed with natural dyes such as madder and safflower dye mordanted with different mordents to similarity for the historical textiles. The wool dyed fabrics were coated with Paraloid B72 adhesive and other samples coated with Paraloid B-72 loaded with clay nanoparticles. The treated wool fabrics aged by accelerated thermal ageing for different time. A comparative study was done in order to characterize changes in properties as well as the physical and chemical degradation of treated wool fabrics before and after thermal ageing. Different type of analysis methods such as tests of surface morphology by using SEM, the colors are given in Commission internationale de l’éclairage (CIE L*a*b*) coordinates, mechanical properties such as tensile strength and elongation, degree of crystallinity, secondary structure analysis by FTIR. This article presents interesting results concerning the effect of ageing on characterization of Paraloid B-72 loaded with clay nanoparticles furthermore for treated wool fabrics. The final aims of this study consolidate and conserve the historic textiles by Paraloid B-72 loaded with clay nanoparticles.
