Abstract:

In order to study the mulberry fruit dyeing cotton fabric properties, this paper researches the mordant dyeing, mordant dyes, temperature, accelerating or retarking process and wet-fastness. Through the experiment and research of the mordant dyeing, mordant dyes, temperature, accelerating or retarding process and wet-fastness, the article proposes two optional mulberry fruit dyeing style used to dye cotton fabric with Fe3+ as mordanting agent, one is using FeCl3 as mordanting agent in the case of pre-mordanting at the indoor temperature and wet condition, the other is using FeCl3, Fe(NO3)3 or Fe2(SO4)3 as mordanting agent in the case of pre-mordanting at the indoor temperature and dry condition. Inthe both of the two dyeing styles, the cotton fabric should be dried before cleaning. In addition, the mordanting agent improves the dyeing behaviors and the order change of the drying and cleaning may affect the wet-fastness.

Key words: cotton fabric, mulberry fruit, Fe3+ as mordanting agent, dyeing
