Red Reactive M Dyes are classified under bright organic substances. These reactive dyes tend to form covalent bond between dye and fiber polymer so that these become parts of applied fibers. Stable electron of such dyes safeguards fiber against adverse effects of UV rays. Chemical bonding of these Red Reactive M Dyes enhances their chemical stability and washability level. Provided dyes have wide applications in textile arena. Standard of these substances has been verified on the basis of their shelf life, colorfastness and processing method.
