Study on the Mechanism of Silkworm Silk Coloring by Adding ‘No2 Red X’ Pigment
To explore the effect of artificial pigments on silk material coloring, ‘No2 Red X’ chemical dyestuff was used in the add-eat experiment of domestic silkworm. The result showed that: there was little effect on silk coloring in 5 instar larvae fed by pigments during the first 4d; while during the late period of 5 instar, added food pigments were transferred to silk gland by blood lymphatic, combined with silk molecular at the state of sorption, and formed natural red silk which was not easy to fade away. This result laid a theoretical basis for the study of artificial production natural color silk.
