Paisan Kongkachuichaya,*, Aroonsiri Shitangkoonb and Nontalee Chinwongamornaa
ABSTRACT: The effects of mordanting method, dyeing temperature and time, as well as the type of mordants used in lac-dyeing process on the properties of silk yarn were studied. Three different mordanting methods, including pre-mordanting, simultaneous mordanting, and post-mordanting, were employed and the amount of adsorbed dye, the quality, and the breaking strength values of silk yarn were compared. Various natural products and chemicals were also used as mordants and they provided finished silk products of different color quality and breaking strength.
