In this work, the dyeing properties of three warm-dyeing reactive dyes (C.I. Reactive Orange 16, Red 198 and Blue 222) for functional viscose/chitin blend fiber containing partially deacetylated chitin were investigated. Under all the dyeing conditions, reactive dyes exhibited higher exhaustion and fixation on viscose/chitin fiber than on conventional viscose fiber. The difference of dye exhaustion and fixation between viscose/chitin and viscose fibers became greater in the following cases: low to moderate dye concentration, low dyeing temperature, no alkali, the use of the dyes with low molecular weight, etc. The dependence of the exhaustion and fixation of reactive dyes on temperature on viscose/chitin fiber was less than that on viscose fiber. The reactive dyeing of viscose/chitin fiber required only a low dosage of sodium carbonate.

Kinetic And Thermodynamic Studies

The natural cationic colorant berberine was used to dye cationic dyeable polyester (CDP) fibers. Its dyeing properties, namely color strength (K/S) of dyed CDP and percent exhaustion (E%) of berberine, on CDP were explored at various dyeing pH levels, temperatures, time, and concentration of berberine. Furthermore, dyeing kinetic and thermodynamic studies were also carried out to evaluate the adsorption properties and mechanism. It was found that theE% of berberine on CDP fibers and the rate of adsorption increased with increasing dyeing temperature, while the influence of pH was extraordinarily small. In addition, the adsorption isotherm of berberine on CDP fibers was in line with the Langmuir model.

Wheat protein composite fiber is a kind of new regenerated cellulose fiber containing protein utilization of wheat bran prepared. The fundamental characteristics of wheat protein composite fiber were studied. The results show that the dry fracture strength is 2.03 cN/dtex and it is lower than that of viscose fiber. It has high moisture regain and low fracture strength and the moisture regain of the fiber is 12.23%. The whiteness of wheat protein composite fiber is lower than viscose fiber. The combustion performance of wheat protein composite fiber is similar to viscose fiber. Compared with wool, the combustion performance is easy. Dyeing properties of the fiber with reactive dyes is excellent and the goods have bright color and good color fastness. The dyeing percentage of direct dyes reached to 90%. The wheat protein composite fiber product is deeply liked by people with its good wearing property, and extensively applied to wear base material with its fine affinity.

Pre Treatment

Silver containing activated carbon fiber (Ag/ACF) has excellent adsorption properties for removing dyes. Silver particles are loaded onto ACF after carbonization and activation at present, and the fibers have low washing resistance and impurities are introduced onto ACF. In this research, pre-treatment techniques were used. Nano-silver solution with a particle size about 10 nm was prepared by using β-cyclodextrin as a stabilizer and reducer, and then the nano-silver solution was used as pretreatment liquid for modifying viscose fiber. Nano-silver particles with functional groups have high activity and can be readily adsorbed on the surface of viscose fibers. Ag/ACF was successfully prepared by carbonizing and activating the Ag-containing viscose fiber. The number and content of nano-silver particles on the surface of ACF was controlled by changing the concentration of nano-silver solution. The results show that the Ag/ACF have a high washing resistance and more efficiently remove methyl orange (MO) and methylene blue (MB) than ACF.
