Abstract:

During the course of this project, a variety of different areas dealing with the aftertreatment of nylon 6.6 dyed with commercial acid dyes was investigated in an attempt to increase the fastness of dyeings to wet treatment. Protease enzyme was used in conjunction with tannic acid in a single-bath, two stage aftertreatment for nylon 6.6 dyed with acid dyes. The effectiveness of this tannic acid/enzyme aftertreatment was comparable to that of six established aftertreatments namely four commercial syntans, the traditional full backtan and a tannic acid/tin system. The metal-free, tannic acid/enz

Abstract:

The colour formers used in carbonless copying paper consist of admixtures of primary and secondary dyes. Work was carried out in this programme both on retarding the photofading of the primary dyes and on improving the reactivity of the clay minerals towards the development of the secondary dye. The photolytic fading behaviour of S primary dyes were examined both in solution and on solid clay surfaces, and the intermediacy of singlet oxygen in the fading processes of the dyes examined by the DPBF trapping method. The retardation of dye fading was accomplished using bis(dithiocarbamato)nickel(I

Routes to novel heterocyclic azo compounds and components of use as potential inkjet dyes were investigated. A new route to fluorenones from biphenyl acid chlorides using FVP (Flash Vacuum Pyrolysis) has been discovered.

The adsorption capacity of the adsorbents varies in the following order : N-SBA-15 > SBA-15. The

碩士<br>義守大學<br>土木與生態工程學系<br>100<br>The objective of this study is to evaluate the effectiveness of using Ultrasound/Fenton for degradation of acid and reactive dyes. Some factors, including pH, Fe(0), H2O2, ultrasonic power level, EDTA, salts, and reused of Fe(0), affect the degradation efficiency were studied. Comparison of different processes, including Fenton, Fenton/US, H2O2/US, Fe(0)/US, and Ultrasonic was carried out and results has shown that a syngistic effecs on Fenton/US process. The results showed that pH,, Fe (0), and H2O2 were the key parameters of degradation of dyes in the Fenton

碩士<br>萬能科技大學<br>環境工程研究所<br>103<br>The potential of adsorptive removal of chloride ions and acid dyes with layered double hydroxides (LDHs) was investigated. The Mg-Al(3:1 molar ratio)–LDHs was firstly prepared with hydrothermal method and then calcined at 300 to 700 ℃ to obtain the adsorbents. The adsorption capacity of chioride ions and acid dyes on the LDHs at different pH values and both the adsorption equilibrium isotherms and kinetic data of ammonium at different temperatures (30, 45, and 60 ℃) were measured. Then, for chloride ions, the adsorption equilibrium isotherms were fitted to the

Generally the industry dye N/C cross woven fabric with the method of two-bath, two-stage. But it is time consuming and required more energy and auxiliary. In this research try to find a new method make the N/C cross woven fabric is able to dye und

碩士<br>國立臺北科技大學<br>有機高分子研究所<br>96<br>In recent years, more and more people are enjoyed in their leisure activities due to the promotion of living quality. Hence clothes with some performance such as water repellent and antibacterial properties are demanded. In our previous work, we have synthesized the dispersive dyes which have water repellent even oil repellent properties. Due to the lower surface tension of perfluoroalkyl group, water can not spread on the surface. Both of the halogens and long chain alkyl group have the function of antibacterial. Consequently, we synthesized a series of aci
