In this work an attempt has been made to optimize the process of dyeing wool fabric with Kamala natural dye, firstly by enhancing the colour strength obtained via treating wool with Safflower enzyme extract. The noticeable increasing in colour strength as a result of bio-treatment with Safflower extract is attributed to the enzyme extract which contains mainly lipase and protease enzymes which improve the dyeability of wool fabrics. All the parameters that may affect the bio-treatment process were studied in details, also the dyeing parameters such as dye concentration, pH value of the dyeing bath; both dyeing temperature and time were studied to determine the optimum conditions for both the treatment and dyeing processes. In order to develop an eco-friendly natural dyeing process that is compatible with the environment, fixation process was made by using pomegranate as a natural mordant for the Kamala natural dye instead of the artificial ones. The factors affecting the fixation process with pomegranate natural mordant were investigated to conclude the optimum conditions of fixation stage. It is obvious from this study the possibility of having bright deep colour from Kamala natural dye on the bio-treated wool fabric with good fastness properties that will match with the recent demands of using eco-friendly materials to be attuned with the environment.

Abstract
In this work an attempt has been made to optimize the process of dyeing wool fabric with Kamala natural dye, firstly by enhancing the colour strength obtained via treating wool with Safflower enzyme extract. The noticeable increasing in colour strength as a result of bio-treatment with Safflower extract is attributed to the enzyme extract which contains mainly lipase and protease enzymes which improve the dyeability of wool fabrics. All the parameters that may affect the bio-treatment process were studied in details, also the dyeing parameters such as dye concentration, pH value of the dyeing bath; both dyeing temperature and time were studied to determine the optimum conditions for both the treatment and dyeing processes. In order to develop an eco-friendly natural dyeing process that is compatible with the environment, fixation process was made by using pomegranate as a natural mordant for the Kamala natural dye instead of the artificial ones. The factors affecting the fixation process with pomegranate natural mordant were investigated to conclude the optimum conditions of fixation stage. It is obvious from this study the possibility of having bright deep colour from Kamala natural dye on the bio-treated wool fabric with good fastness properties that will match with the recent demands of using eco-friendly materials to be attuned with the environment.
