AIC 53rd Annual Meeting

This study offers comparative results concerning the effect of bio polymer as gellan gum and synthetic polymers as polyacrylamide Loaded with different cleaning agents as protease enzyme and siloxan D5 according to type stain on dyed wool fabric before and after thermal ageing and different periods of application time.

Dyed textiles in museums sometimes are exposed to various types of stains which contributing degradation of fabric and effect on dyes. Using of uncontrolled treatment can cause dye bleeding and shadow lines, therefore, this study presents a practical stain reduction on dyed wool fabric mock-ups using gel poultice cleaning treatment by Protease enzyme and siloxan D5 cleaning materials separately loaded poultices of 2% gellan gum or acrylamide carrier. The protease enzyme poultices target to reduce animal glue stain where siloxane D5 poultices target to reduce the blue ink pen stain. 

The main purpose of this practical study to evaluate the efficiency of bio and synthetic polymers loaded with cleaning materials in reducing ink and animal glue stain and characterize changes in red dye of treated wool fabrics before and after thermal ageing through three different periods (zero ageing, 72 hrs and 144 hrs) at 100 oC taking into consideration that, the application of each poultice on the stained samples was tested for different periods of application(30,60,90 min) through different type of analysis methods as color measurements according to CIE lab system. SEM analysis is used to study the surface morphology of dyed fabric before and after treatment. EDX analysis is used to study gel cleaning efficiency by detecting the presence of residues.
