The removal of hemoglobin from acrylic acid grafted Nylon fabrics has been investigated. In order to change detergency of Nylon 6 fabric, acrylic acid(AA) were graft copolymerized on Nylon fabric using ammonium persulfate(APS) as a initiator, and then acrylic acid grafted Nylon was treated with NaOH solution. The graft ratio increased linearly with increasing acrylic acid concentration. The graft ratio was the highest when the concentration of APS was 0.05%, and it decreased as the concentration of APS increased. The surface of Nylon fabric became rough due to graft. Moisture regain was increased by graft and alkaline treatment, contact angle was also improved compared with the ungrafted. The hemoglobin was easily solubilized and removed from grafted Nylon fabric, while it was difficult to remove hemoglobin from ungrafted Nylon fabric. The effects of graft on removal of hemoglobin was related with increase of moisture regain and transformation of COOH to COONa by alkaline treatment.
