Some Observations on the Kinetics of Dye Fading All lightfading rates of dyed or pigmented materials can be divided into five main classes and some subgroups, according to the shape of the arithmetic plot of rate of loss of dye. The physical condition and environment of the coloring matter appear to be principal factors determinipg the shape; a change in concentration does not usually change the class of fade. Class I... ...

Photofading of Azo Pyridone Dyes in Solution We report on the investigation and kinetic measurements of the photofading process of some o-, p-substituted azo pyridone dyes in formamide, N,N-dimethylformamide, and N,N'-dimethylacetamide. The free energies of solvation of dyes in the three solvents have been calculated by measuring the distribution coefficients of the dyes between the amide solvent and n-hexane as the immiscible stand... ...

Anomalous Lightfastness in Disperse-Dyed Systems and its Significance in Studies of Fading Mechanism A few dyes and fluorescent brightening agents of disperse type, in hydrophobic substrates, show anomalous fading characteristics, i.e., reduced lightfastness with in creased dye concentration, a reversal of the normal trend. Measurements, by the density gradient method, of the change of apparent specific gravity of dyed film material with change in dye concentration reve... ...

Photolytic Behavior of Some Popular Disperse Dyes on Polyester and Nylon Substrates The photodegradation products that form when disperse red 1, red 17, and blue 3 dyed fabrics and films are exposed to carbon arc and xenon arc light sources have been identified. The effects of black panel and dye carrier on the nature of the deg radation products and the fading process itself were also studied. The results of this research indicate that the same photodegradation products... ...

Bioactivation of PET woven fabrics using alginate biopolymer and the bacteriocin nisin Bioactive antibacterial PET (polyethylene terephthalate) woven fabrics were produced by fixing a thin alginate coating with entrapped nisin at the PET fiber surface. These textiles may find applications in the field of hygiene or food packaging. In the first part of the study, thin solid alginate films (without nisin) capable of forming hydrogels in aqueous medium were deposited at the PE... ...

Filtration performance of electrospun polyamide nanofibres loaded with bactericides Electrospinning is a process to generate nanofibrous nonwovens. With these nonwovens, many applications can be targeted, such as water filtration. In this paper, polyamide nanofibrous membranes are evaluated for their pore size, a key parameter in water filtration, and for their removal of microorganisms. To increase the removal efficiency to values exceeding the state of the art, innovat... ...

Coloration of different textile fibers using glycerol oxides We have investigated new applications of the Maillard reaction in textile industries as an alternative to conventional dyeing methods. Our previous paper indicated that only textile fibers having amino groups, such as wool, silk, and nylon fibers, were colored by chemical reactions with reducing sugars, such as d-glucose and d-xylose, but these coloration reactions were very slow compared... ...

Coloration of polyamide fibers in an aqueous solution by Maillard reaction Polyamide fibers, such as wool, silk, and nylon fibers, could be colored in an aqueous solution containing reducing sugars, similar to the coloration of various foods containing both protein and reducing sugars, by the Maillard reaction. For example, the color of the wool fibers reacted with xylose, one of the reducing sugars, was changed in succession from beige to yellow to orange with ... ...

Sorptive Textile Systems Containing Activated Carbon Fibers Activated carton fabrics and yarns were shown to effectively sorb gases, vapors, and dissolved solids. Fabrics pre pared by Arons and Macnair (phenotic precursor) and Maggs (viscose precursor) were the most activated of all the materials studied. The yarns had a lower activity but probably can be improved to have comparahly high sorption capacity. Other materials studied included permeabl... ...
