Recently, interest in environment-friendly natural dyeing has been relatively increased as interest in environmental and health issues has increased (Oh, Jung, 2001). Natural dyes have been reported to have various functionalities such as antimicrobial and deodorizing properties depending on the color of the dyes used and natural dyes (Jia Jung, 1996; Jung Jin Soon, 1997; Natural dyeing products have these advantages, but they have a drawback in that they have a lower fastness to dyeing with synthetic dyes, such as fastness to light, wash fastness, perspiration fastness. Therefore, in order to commercialize a natural dyeing product, it is necessary to increase the fastness first.

In order to improve the fastness of natural dyed products, some dyes may be treated with soybean juice, tannin, impurities, glutinous rice bran, etc., but the use thereof is complicated and there is a problem that it is selective depending on dyes. The chemicals made for the purpose of improving the fastness are effective, but in the case of natural dyeing, the significance of natural dyeing is lost.

As shown in Table 4, the rock-dyed fabrics were superior to the washing fastness acetate and the water fastness as the whole as 4-5 grade. However, in the case of washing fastness change, it was somewhat lower in 2-3 grades. In the case of treated with 0.5 wt.% And 1.0 wt. Therefore, although the treatment of bean sprouts was not clear, it was found to be somewhat helpful in improving the fastness.

3. conclusion

The addition of butterflies did not affect dyeability in the loess and rock staining. However, when 0.5% by weight and 1.0% by weight of beeswax were treated in yellowing, the fastness to discoloration in the wash fastness was increased to 3 and 4, respectively. When treated with 0.0 wt.% And 0.1 wt.% Of rock dyed tryptic bean sprouts, it was classified as 2-3, 0.5 wt.% And 1.0 wt. Given these results, it is possible to improve the color fastness to color change in wash fastness by dyeing as shown in Figs.
