In this context, the new zinc (lignin /silica /fatty acids) complex derived from rice straw, was utilized as an antioxidant and activator in rubber composites. In addition, the novel non-toxic semi-natural antibacterial cyanoacetyl microcrystalline cellulose was utilized to prepare safe azo disperse dyes then the new dyes were utilized for silk screen printing polyester and nylon 6 fabrics. In addition, antibacterial membranes were prepared by the blending of novel nontoxic semi-natural antibacterial biodegradable cyanoacetyl microcrystalline cellulose with cellulose acetate UR - http://172.23.153.220/th.pdf ER -
