In this article, with more than 30 pieces of silk dyeing with disperse dyes with different structures, filter by measuring its rate of dyeing dyes, and determination of its promotion, discovery of Longsheng group in the proction of heat-UN-SE and EE series of disperse dyes have good lifting. Simultaneous determination of dispersion rate of dyeing curve of Red jade S-2GFL, found in 95, 90 ° c under the conditions of dyeing, dyeing balance when 20 MHz respectively, it's added o to join the slight increase in the rate in the early, but on balance would not seriously affect rate of dyeing. 1:1 standard color depth by measuring the color fastness of dyed samples found that rubbing fastness of disperse dyes on silk is better, but weak washing fastness, will be the biggest technology challenges of silk dyeing with disperse dyes.热心网友 时间:2023-11-02 15:10
In this paper, using more than 30 different structures of disperse dyes on silk fabric dyeing, by measuring the percentage of exhaustion were screened to determine the dye, lifting, found Zhejiang Longsheng group Limited by Share Ltd proction of medium temperature type UN-SE and EE series disperse dyes have good upgrade.Simultaneous determination of the dispersing ruby S-2GFL dyeing rate curve, found in 95, 90 ℃ staining, respectively in 20, 60min to dyeing equilibrium, peregal O was added to make initial dyeing rate increased slightly, but had little effect on the equilibrium dye uptake.Through the determination with 1:1 standard color sample dyeing color fastness of deep value discovery, disperse dyes on silk fabric rubbing fastness is good, but the washing fastness of disperse dyes dyeing of silk, will become the most difficult problems.(可以吗,望采纳)热心网友 时间:2023-11-02 15:11
