| Abstract | ||
| Bioremediation using enzymes is an important tool in textile industry; therefore the goal of the present study is to subrogate the pretreatment of natural (cotton) and recovered (viscose) cellulosic fabrics with microbial acidothermophilic cellulase produced by the native Egyptian fungus Aspergillus terreus RS2. The produced enzyme was examined at two activity levels (10 and 20U/mL) in order to reduce the effluent load that was produced from scouring and bleaching processes and to upgrade a naturally adequate transaction for water and power economy. The effectiveness of the enzymatic pretreatment under the optimum conditions on raw, scoured and bleached cellulosic fabrics has been proved as the results indicated an increase in the color intensity of the treated fabrics in compare to the untreated one for different classes of reactive dyes based on Anthraquinones and Double azo. The fastness properties of the pretreated dyed fabrics were implemented. The contact angle for the pretreated cellulosic fabrics, tensile strength, Scanning electron microscopy and FTIR analyses were performed. | ||
