Fragile textiles in museums need to consolidate by natural adhesives such as animal glue due to conservation process. Sometime the animal glue becomes shrunk, cracked, and rigid after long term. The article is aimed to study using Nano animal glue 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 Nano animal glue 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 animal glue adhesive and nano animal glue adhesive. The treated wool fabrics were 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 SEM , FTIR, the colors are given in Commission internationale de l'éclairage (CIE L*a*b*) coordinates and mechanical properties. This article presents interesting results concerning the effect of ageing on characterization of nano glue adhesive furthermore for treated wool fabrics.
