吸潮放置对还原红、还原蓝、还原橄榄变色的影响OA

In the actual production,storage and application processes of reductive dyes,environmental humidity has a significant impact on their color stability.Based on different manufacturers and models of reductive dyes,this study systematically analyzed the effects of moisture absorption on the color changes of three typical reductive dyes:reductive red,reductive blue,and reductive olive.Combined with practical production experience,it also discussed corresponding prevention and control measures.The results show that different manufacturers and models of reductive dyes have signifi-cant differences in their sensitivity to humidity and the direction of color change.The basic manifestation is that the color becomes lighter and the color light deviates.By optimizing based on color measurement data,three stable dyes with good stability were selected:reductive blue DB from Shandong Siren De,reductive olive T from Shandong Siren De,and reduc-tive F3B red from Jiangsu Walde.When these dyes are compounded and used to dye fabrics,the color depth and color light of the dyed fabrics remain basically consistent after being placed in a humid environment,and the color fastness are all above 3 grades.
