  • The preparations of deodorizing fibers using medal-phthalocyanines have been investigated. The five metal-phthalocyanine derivatives(M-taPc, M=Fe, Co, Ni, Zn, Cu) were prepared in modest to good yields. The metal-phthalocyanine derivative as a deodorant material was introduced to fibers by a dyeing method. The deodorant activity(D.A.) of these deodorizing fibers was measured by chromogenic gas detector tubes. In comparison with untreated fibers, these deodorizing fibers was remarkably effective against $NH_3$ and CH3SH. More than 99% of ammonia can be removed within 20 min. The D.A.(%) of fiber adsorbed M-taPc was more than 80% after 90min.

  • The preparations of deodorizing fibers using $TiO_2$ have been investigated. The fibers were coated with $TiO_2$ for the purpose of deodorizing by dipping fibers into the $TiO_2$ sol solutions and calcined at $450^\circ{C}$, $500^\circ{C}$ and $750^\circ{C}$ for 1 h after coating. The surface structure of the coated fibers was studied with XRD on the different preparation conditions of calcination temperatures. The deodorizing function of the prepared fibers was studied by the determination of the decomposing capability for $NH_3,\;CH_3SH\;and\;CH_3CHO$. The deodorant activity(D.A.) of these deodoriBing fibers was measured by chromogenic gas detector tubes. The deodorizing effect of the prepared fibers were shown to be similar for the three model compounds; 5wt% $TiO_2$ sol solution calcined at $450^\circ{C}$ < 5 wt% $TiO_2$ sol solution calcined at $500^\circ{C}$< 5 wt% TiO$_2$ sol solution calcined at $750^\circ{C}$.

  • The preparations of deodorizing fibers using metalloporphyrines hove been investigated. The three metalloporphyrin derivatives(MTCPP, M=Mn, Zn, Sn) were prepared in modest to good yields. The metalloporphyrin derivative as a deodorant material was Introduced to fibers by a dyeing method. The deodorant activity(D.A.) of these deodorizing fibers was measured by chromogenic gas detector tubes. In comparison with untreated fiber, these deodorizing fibers was remarkably effective against $NH_3$ and $CH_3$SH$. More than 98% of ammonia can be removed within 20 min.. The D.A.(%) of fiber adsorbed MTCPP was more than 80% after 90min..

  • The preparations of deodorizing fibers using $\textrm{TiO}_2$ have been investigated. $\textrm{TiO}_2$ is known to be an excellent photocatalyst for the degradation of organic and inorganic contaminants in water. $\textrm{TiO}_2$ catalyst have been supported on the glass fiber by a dip-coating procedure. The resulting materials have been characterized by XRD and SEM. The immobilized catalysts were tested in the photocatalytic degradation of $\textrm{NH}_3$, $\textrm{CH}_3\textrm{SH}$ and $\textrm{CH}_3\textrm{CHO}$. The deodorant activity(D.A.) of these deodorizing fibers was measured by chromogenic gas detector tubes. The efficient deodorant activity results have been achieved through the increase of $\textrm{TiO}_2$ sol concentration.

  • Both cellulose and chitin together were dissolved in DMAc/LiCl and these solutions were extruded into coagulant of $DMAc/H_2O$. Fibers thus obtained were treated in NaOH aqueous solution. Results showed that the fiber surface contains celluose and chitosan. This means that these fibers treated are composed of three components, ie, cellulose, chitin, and chitosan. These fiber showed secure antibacterial and mechanical properties.

  • Deep coloration of cotton fabrics with concentrated Rhus verniciflua extract was carried out using large amount of Glauber's salt and a mordant in order to improve dyeability and functional properties such as deodorizing and antimicrobial activity. With increasing in the salt addition upto 80% in the dyeing liquor containing 0.45% extract concentration, K/S value and exhaustion increased threefold from 1.2 to 3.5, indicating that the salt reduced the electrostatic repulsion between the dyes and the cotton fibers. Also the concentrated extract solution to 8% can increase the color build up upto a K/S of 11.1. In addition the combined pre- and post-mordanting methods with potassium alum enhanced the dyeability upto a K/S of 22.2. The ammonia deodorizing property increased with increased color yield of the dyed fabrics. Also the dyed and post-mordanted fabrics with 8% extract concentration showed antimicrobial activity against both Klebsiella pneumoniae and Staphylococcus aureus.
