    The methylene blue and dyestuff removal efficiency in a textile factory by ozonation and/or carbonaceous material treatment was investigated. Three kinds of carbonaceous materials were prepared from wool(WL), polyester(PET), and cotton(CT)discharged from the textile factory. The physical properties of the carbonaceous materials were very different. The specific surface area and pore volume of WL were the lowest, while those of CT were the highest. The dyestuff removal efficiency from actual dyestuff water was the highest when using the carbonaceous material(CT)prepared from cotton waste fiber. The decreases in the chromaticity, turbidity, COD, and TOC of the actual dyestuff wastewater depended upon the mean pore diameter of the carbonaceous material. The COD and TOC of the actual dyestuff wastewater were only slightly decreased by ozonation. The ozonation with CT would be useful for the removal of the dyestuff from actual textile wastewater. These results indicated that the waste cotton fiber could be converted into a carbonaceous material as an adsorbent for the removal of dyestuff from actual wastewater.

    The changes in morphological structure and physical properties of human hair by the three types of solvent extraction have been investigated in detail. The transmission electron microscopy revealed the following features. The hair fibers treated with formic acid and acetic acid were characterized by the extended unstained band in cell membrane complex(CMC)between cuticle cells, indicating the severe structure damage to CMC. The hair fibers treated with ethanol/chloroform were characterized by lack of β-layers in the CMC of both cuticle and cortex. In the fibers treated by boiling water, the density distribution of staining in the β-layer of the CMC between cuticles appears to be intermittent and the boundary between β-layer and δ-layer in the CMC of cortex was markedly obscured. Differential scanning calorimetry indicated that the enthalpy of the endothermic peak for extracted specimens decreased compared with that of untreated one, suggesting the reduced structural rigidity of the macrofibril in the cortex cells. The rigidity of hair treated with formic acid and acetic acid was clearly lower than that of other samples. On the basis of these findings, we discussed again about the effects of the constituent components of hair fiber on the mechanism of the permanent wave formation.

    Most of the elderly patients confined to bed suffer from the case of contracted hands and are unable to open their hands freely. Since they grasp the hands tightly all the time, the contracted hands generate foul smell like degraded aliphatic acid products and also cause the skin disease such as athlete's foot by Trichophyton. In the hospital, a rod-like tool made of soft fabric is conventionally applied to the palms of those patients to prevent from injuring the palm skin, but it does not help to suppress a foul smell generation due to an unhealthy condition of the skin. In order to solve this problem and improve the patient room environment, we applied a deodorant as well as antibacterial cotton fabric processed with iron(III)tetracarboxyphthalocyanine-processed and cupper(II)tetraammine. Iron(III)tetracarboxyphthalocyanine is known as an artificial oxidase-like enzyme, and cupper(II)tetraammine functions synergistically with this artificial enzyme to suppress foul smell and bacteria growth. The clinical test confirmed that foul smell from contracted hands was reduced to “very weak” by applying a hand grip made of new processed cotton fabrics after 4 days. The diseased skin(typically observed between fingers and palm)exhibited a symptom of recovery to its healthy sate after 3 or 4 days, and most of the athlete's foot symptom disappeared after 1 week.
