I analyzed the pigment properties of extracts extracted in a Perilla Frutescens L. Britt by three solvents of distilled water, 3% sodium hydroxide, and ethanol, dyed them into the silk fabrics, and then looked into the functionality of the dyed silk fabrics by analyzing the differences that changes by analyzing the differences that changes in the dyeing conditions affect the dyeing properties. Also, I mixed after putting the Perilla Frutescens L. Britt ethanol extracts in a high polymer solution of PVA, analyzed the form and the characteristics of PVA nanofiber produced by an electric radiation, and then drew a conclusion as follows:
1. As the results of analyzing the ultraviolet·visible absorption spectrum, FT-IR, GC-MS of extracts extracted in a Perilla Frutescens L. Britt by three solvents of distilled water, 3% sodium hydroxide, and ethanol, and the results of measurement and analysis of the ultraviolet·visible absorption spectrum, FT-IR, GC-MS by extracting the Perilla Frutescens L. Britt''s ingredients with the distilled water, the 3% sodium hydroxide, and the ethanol, it was confirmed that it is the polyphenol and flavonoid compounds materials extracted by the Perilla Frutescens L. Britt, the distilled water, and the 3% sodium hydroxide are a main ingredient of tannin extracted by the Perilla Frutescens L. Britt. Ethanol are a main ingredient of chlorophyll, furan chemicals, sesquiterpenes, and esters.
2. Among Perilla Frutescens L. Britt extracts, the total polyphenol content of the distilled extract was the most with 92.82mg/g, the content of the ethanol extract was 51.20 mg/g, and the content of 3%NaOH aqueous extract was measured 11.10 mg/g. The total flavonoid content, the ethanol extract was the most with 65.02 mg/g, distilled water extract was 13.13 mg/g, and 3%NaOH aqueous extract was measured 9.86 mg/g. After the results of the total polyphenol and the total flavonoid contents of Perilla Frutescens L. Britt extract were examined, the distilled extract was higher than the total polyphenol content of the existing medicinal plants such as Pueraria thunbergiana, cornus officinalis, schisandra chinensis, the total polyphenol and the total flavonoid contents of the ethanol extract was higher than the contents of most medicinal plants.
3. Extraction yield by distilled water was 14.94%, the yield by 3%NaOH aqueous extract was 16.7% and the yield by ethanol was lower than that showing 6.35%. Silk fabrics dyed with each extract suggested that the dyeing uptakes increased as dye concentrations, dyeing temperatures and time of the extract increased, and decreased as pH of the extract increased. The dyed fabric without a mordant produced Y-series colors and showed various other colors depending on the mordant types.
4. as the results of evaluating fastness of sil fabrics dyed with the Perilla Frutescens L. Britt extract, the color fastness to washing of untreated fabrics dyed was higher than the fabrics treated with mordant dyes, so the mordanting treatment lowered the color fastness to washing. The color fastness to light was slightly increased, but it generally appeared to be low, on the other hands, the rubbing fastness and the color fastness to perspiration showed excellent results of a grade 4 to 5 in a change in the color and a pollution.
5. The original amount of the dying made by the extracts of the Perilla Frutescens L. Britt by the distilled water and the ethanol as a functional purpose showed a high antibacterial activity. It is considered as the Perilla Frutescens L. Britt extracts applicable to various fiber materials such as antimicrobial medicated foam. However, the antimicrobial activity of the dyed silk fabrics appeared not to be high, so further research to enhance the antimicrobial activity of the dyed fabrics is necessarily required. Deodorant properties of the silk fabrics dyed with the Perilla Frutescens L. Britt extracts can be increased.
6. It was confirmed that the viscosity of the high polymer solution of PVA is increased up to 1462~2678cp as the Perilla Frutescens L. Britt ethanol extracts are added, in the viscosity of the Perilla Frutescens L. Britt /the PVA solution, and the diameter of the nanofiber is increased up to 276.2~319.8nm as the Perilla Frutescens L. Britt extracts are added, but there was no significant differences although the content of the Perilla Frutescens L. Britt extracts is increased. Also, it was checked that a uniform nanofiber can be produced when the content of the Perilla Frutescens L. Britt extracts is 0.25~1wt% as the essential oil composition of the Perilla Frutescens L. Britt extracts is not well dispersed in 1.5wt%, making beads.
7. As the results of an analysis of FT-IR, XRD, and DSC, a hydrogen bonding between the Perilla Frutescens L. Britt extracts molecules and the high polymer of PVA and the resultant interaction were done well, and it was confirmed that there was no significant differences in the produced nano web''s melting point and the thermal decomposition capacity as the content of the Perilla Frutescens L. Britt extracts is increased, and the Perilla Frutescens L. Britt /PVA nanofiber was found out that the nanofiber in a state, which a bond between the molecules is made, is produced. With the results of the research to make a comparison between the dye properties, extracted by the three extraction solvents, changes in the color of the dyed silk fabrics, and the color fastness, I could know about the Perilla Frutescens L. Britt is a polygenetic dye which can various colours according to the dyeing conditions and the mordant because the Perilla Frutescens L. Britt has all of the water-soluble and non-water-soluble dye. The other fastness items excluding the fastness to light showed the excellent ratings, and it is considered as it can be utilized as a practical fabric. Also, it can be utilized as a functional fabric to consumers seeking for well-being due to the fact that it showed the excellent results in an evaluation of the deodorant properties of the dyed silk fabrics. Finally, I checked that a composite nanofiber can be produced through the electric radiation process after adding the Perilla Frutescens L. Britt extracts extracted by the ethanol into the high polymer solution of PVA as an applied research.
