Description
Silk plain Habutae immersed in distilled water, NaOH solution (pH=130), Marseilles soap solution, SDS solution, ABS solution and alkaline ABS solution for 48 hours were rubbed by the use of apparatus for testing of color fastness to rubbing. Their physical properties were investigated.
In the wet state the decreases of tensile strength and elongation of rubbed plain Habutae which were immersed in alkaine water and surfactant solutions were less than that immersed in distiued water. The tensile strength and elongation of dried samples after rubbing in wet state decreased than those of samples rubbed in dry state, regardless of the kinds of solution.
The distribution curves of reflection strength of rubbed plain Habutae which were immersed in various kinds of solution were investigated. The curves of rubbed samples immersed in alkaline water and surfactant solutions appeared the reflection peaks at 0°,45°,90°,135°,and 180°same as the curve of unrubbed Habutae, but in the curve of rubbed sample immersed in distilled water, these peaks were disappeared.
It was found that rubbing endurance in the surfactants solution was less than that in the distilled water.
