Optimization of Cleaning Condition of Historic Textiles Based on Iranian Ancient Texts

Abstract

This paper studies the fourth principle of Allama Shirazi Kendi treatise related to the Hegira 11th century about use of two materials of Arabic gum and plant Seidlitziarosmarinus in order to remove pomegranate juice stains from textiles. The investigation with the aim of reviving the traditions is focused on realizing how and why the use of the mentioned materials in removing juice stains from cotton textiles is discussed. Since removing the pomegranate juice on cellulosic fibers because of chemical bond establishing with the fiber is difficult, materials used such as Arabic gum (Acacia Senegal) and Seidlitziarosmarinus (Chenopodiaceae) in terms of composition and effectiveness of the method has been studied experimentally. To simulate the experimental sample, parts of cellulosic fabrics was used and impregnated and stained with pomegranate juice. Highlights of this recipe are conditions and the execution of the mentioned process which by the CCD (Central Composite Design) is capable simultaneously design and optimize the independent variables such as temperature, time and other interfering factors in the cleaning operation. Evaluation of performance of materials used was done by a Reflection Spectrophotometer that while confirming the effectiveness of the material being presented, results in achieving optimal conditions on using materials with a high degree of desirability.
