The results of the analysis of dyed rayon fabrics treated with persimmon juice by padding are as follows. Rayon fabrics were dyed repeatedly with persimmon juice by a padding mangle for the development of dyeability. The merits of padding-based dyeing were easier color reproduction (versus traditional hand dyeing) of hard to obtain colors and color fastness to light and laundering. The add on weight increased with the number of padding times, and the color of the dyed fabrics had red-yellow colors with low brightness and high chromatic colors. Properties of fabrics treated with persimmon juice were: $2^{nd}$ level of light resistance, $4^{th}-5^{th}$ perspiration fastness levels, rubbing fastness, and $3^{rd}-4^{th}$ washing fastness levels. Dyed fabrics exposed to UV light have a deep yellow-red color that increased lightness and darken when exposed to sunlight. Rayon fabrics of a treated premordant indicated strong yellow colors, especially fabrics with Fe mordant indicated greenish red-yellow colors. The direction of the weft and warp increased and improved water-repellent qualities that increased with the number of dyeing padding times and persimmon juice; however, there was less anti-crease resistance. In addition, fabrics had good antibacterial activity and deodorization.

This research from analyzing dyed silk fabrics treated with persimmon juice by padding concludes as follows : The add on is increased as the number of padding increase and the color of the dyed fabrics holds red-yellow colors which has low brightness and high chromatic colors. The fabrics dyed with persimmon juice have properties such as 2nd grade of light fastness, 4~5th grade of perspiration fastness and rubbing fastness, and 3~4th grade of washing fastness. The dyed fabrics exposed to UV light have deeper yellow-red color than things exposed to sunlight. The silk fabrics treated premordants have shown strong yellow colors, especially the fabrics added Fe mordant have shown greenish red-yellow colors. As the padding times of dyeing with persimmon juice are increased, strength and water-repellent property are enhanced along warp and weft direction respectively but anti-crease property is decreased. Also, the dyed fabrics have good antibacterial activity and deodorization.
