Fiber waste arises when towels are produced. We made two kinds of different mass paper by blending fiber waste of towel with virgin pulp. We also made two kinds of paper made of only virgin pulp for comparison. We measured and estimated the basic characteristics. We made the simple experimental device to illumination characteristics about these samples. Using this device, illumination of transmittance could be measured. We set three factors as follows ; light, distance between light source and position of sample and moved distance of measuring point. The first factors and the second factors have three levels. The third factors have fifteen levels. The result showed the difference of illumination by moved distance between paper blended fiber waste and paper made of virgin pulp. In addition to this, I had my students answered questionnaire about transmittance state of 4 kinds of papers. We made it clear that the paper blended fiber waste was better disposed than paper made of virgin pulp.
