수목 추출물 처리에 따른 면 편성물의 염색성과 기능성 연구- 두충나무 추출액을 중심으로 -

Abstract

This study tries to examine the dye-ability and functional effects of a material that has economic values and pharmacological components, when dyeing solution are extracted from it, which in turn are processed into fabrics. Eucommia ulmoides Olive which are taken as an oriental medication were used as our material to extract dyeing solutions, and then we made an experiment about their functional effects and analyzed the results when they were used for children’s and patients’ clothes and underwear. The results are as follows. The Colorfastness to Washing, Rubbing, and Perspiration of the experimented samples were very excellent, but its Colorfastness to Light was low as were ranked at the 2-3 degrees. The surface colors of the samples were red-tinged yellow or yellow-tinged red. When iron mordants were used among others, the brightness turned out to be high, and the samples were red-tinged in the case of pre-mordanting while yellow-tinged in the case of post-mordanting. Color differences were the most striking between the sample processed for 60 minutes at 90℃after pre-mordanting and that processed for 30 minutes at 90℃. After all, it has turned out that the proper temperature and time length for dyeing with Eucommia ulmoides Olive extract are 90℃and 60 minutes for pre-mordanting and 60℃and 90 minutes for post-mordanting. As a result of the experiment about the deodorizing properties and antibacterial effects of the samples, it turned out that they were excellent with a reduction rate of 99.9%. Formaldehyde was not detected. With the results above, I can tell that the components of the Eucommia ulmoides Olive are dyeing materials that have hygienic properties necessary for functional clothes, underwear and bedclothes, and abilities to meet the functional conditions on the protection of skin. That is to say, use of Eucommia ulmoides Olive as an economic and human body/environment protecting material for fabric processing can make a contribution to the development of new eco-friendly products. In addition to the results of this study, I believe that parallel use of natural dyes with high dyeability sould be continued in future.
