The effects of culture medium components and dyeing conditions on dyeing properties were investigated. It provided a theoretical basis for the application of microbial pi
8、gments in the field of textile dyeing. The Aspergillus niger spores powder was applied in dyeing of silk and wool. The effects of carbon source and nitrogen source, dyeing temperature, pH value, dyeing time and the dosage of Aspergillus niger spores on dyeing properties of silk and wool fabric were
9、investigated. The leveling property, dyeing penetration, color fastnesses of the dyed fabrics were also studied. The results showed that, The addition of suitable carbon source and nitrogen source was helpful to improve the K/S of dyed fabrics, the best mass concentration was 3g/L and 5g/L, respecti
10、vely; within a certain range, the K/S values of dyed fabrics increased with the increase of dyeing temperature, pH value or dyeing time; The leveling property and dyeing penetration of dyed fabric were relatively good. It was found that better color depth and good fastness of dyed fabric could be ob
11、tained under the optimal dyeing process, pH=7, T= 30 C,t= 24h. Secondly, the fermentation of making yellow pigments from Trichoderma viride was studied. In order to observe their growth and the ability in producing yellow pigments, the Trichoderma viride was grown on a potato dextrose culture medium
12、. The effect of process parameters of producing yellow pigments such as carbon source and nitrogen source, pH, culture temperature and culture time have been studied and the conditions were optimized. The results showed that, Trichoderma viride was grew well and able to produce the water-soluble yel
13、low pigment on potato dextrose medium. In the UV-Vis absorption spectra of the yellow pigments, the maximum absorption wavelength was observed at 390 nm. The yellow pigments production was affected by Medium composition and culture conditions. It was found that more yellow pigments could be obtained
14、 under the optimal Medium composition, 35g/L glucose, 7g/L urea, Na2HP 4 3g/L, 2g/L MgS 4.7H2 . The m Abstract Dyeing of protein fibers with microbial optimal culture conditions was as follow: inoculum 4% (v/v), initial pH = 6, T=30 C, t=3d. Finally, the effects of pH, temperature and metal ions on
15、the stability of the yellow pigments from Trichoderma viride were further studied. The effect of process parameters of dyeing such as dyeing method, pH, dyeing temperature and the dosage of mordants were discussed and the color fastnesses to washing and rubbing of the yellow pigments in silk and woo
16、l fabric were also investigated. The results showed that, the acid-base stability of the yellow pigments from Trichoderma viride is good, but the thermal stability is poor. Fe2+, Fe3+ and Cu2+had a greater impact on the stability of the yellow pigments. To obtain better color depth and good fastness
17、 of dyed fabric, the optimal dyeing process was as follow, pH=4, T=70C for silk fabric and T= 80 C for wool fabric. For mordant dyeing with praseodymium chloride and mixed rare earth, the best dyeing method for silk fabric and wool fabric was simultaneous mordanting method and pre-mordanting method,
