현대인들은 헤어컬러링을 통하여 아름다움을 표출하는데 반복적인 화학적 시술에 의하여 모발은 손상을 받는다. 염색의 지속력을 높이고 모발 손상을 최소화하기 위해 본 연구에서는 헤어컬러링 시 산성 아미노산인 아스파트산(Asp)과 글루탐산(Glu)으로 모발을 후처리하였다. 탈색모에 체리레드와 블루실버 색상으로 염색하고 0.75%의 Asp와 Glu 용액을 실온에서 20분간 후처리를 한 후 1회, 5회, 10회, 15회, 20회, 25회 샴푸 후 L^*a^*b^*값을 측정하여 염색 지속력을 확인하였고, 모발의 상태를 알아보기 위하여 모발의 인장강도, 기공도, 표면 특성의 변화를 분석하였다. 체리레드와 블루실버 염색을 진행한 경우 모두 Asp와 Glu 실험군이 대조군 보다 높은 색 지속력을 보였고 Asp와 Glu 실험군은 대조군보다 높은 인장강도, 낮은 기공도, 매끄러운 표면특성을 나타냈다. 특히 Asp 실험군이 Glu 실험군 보다는 우수한 색 지속력과 낮은 모발 손상도를 나타냈다. 따라서 본 연구가 현장에서 탈색과 염색 시 손상된 모발의 후 처리제로 Asp와 Glu을 조합한 모발 화장품 개발의 기초자료가 되기를 기대해 본다.

The purpose of this study is to investigate the loess dyeability of soybean fabric using loess as colorants. Recent days, various textile products such as inner wears, sheets and interior goods are manufactured using materials dyed with loess emphasizing its improved metabolism, anti-bacterial, deodorizing properties, and far infrared ray emissions. Soybean fabric was dyed with loess solution according to concentration of loess, dyeing temperature and dyeing time. To improve washing fastness, soybean fabric and dyed soybean fabric with loess were mordanted by mordanting agents such as sodium chloride(NaCl), Acetic acid(CH₃COOH) and Aluminium Potassium Sulfate(AlK(SO₄)₂·12H₂O). Dyeability and color characteristics of dyed soybean fabric were obtained by CCM observation. Particle size distribution of loess, the dyeability(K/S) of soybean fabric, morphology and washing durability of loess dyed soybean fabric were investigated. The results obtained were as follows; Mean average diameter of loess was 1.08µm. The main components of loess used in this study were silicon dioxide(SiO₂), aluminium oxide(Al₂O₃), and iron oxide(Fe₂O₃). The content of these three component was above 75 weight %. The dyeability of soybean fabric was increased gradually with increasing concentration of loess. The optimum dyeing temperature and dyeing time were 90℃ and 60minutes expectively. The fastness to washing according to concentration of loess and mordanting method indicated good grade result as more than 4 degree in all conditions.

This thesis aimed to reduce the differences of hair color when hair coloring, so it researched the differences & changes in hair color before shampoo v.s. after shampoo and dry on different heat processes when acid hair color dyeing. Five hair color dyes (Y, R, B, G, Br) manufactured by two different corporations were used. The acid hair color dyes were tinted on black and bleached hair pieces subjected to 3 different heat process; 1. Normal Temperature($25^{\circ}C$, 30min.) / 2. Heating($40^{\circ}C$, 15min.)+Normal Temperature($25^{\circ}C$, 15min.) / 3. Heating($40^{\circ}C$, 30min.). Color numbers were divided by NCS value, chroma, and hue. Statistical averages were derived and t-test was conducted using SPSS V12. Hair color differences and changes were drawn on an NCS chart using Photo Shop PS. The conclu is; If acid hair colorings are separated by a heating process, hair value & chroma change before shampoo vs. after shampoo & dry regardless of the color of hair and the heat process. Hue is not changed or shifted counter clockwise NCS color circle, but some exceptions, and it's the same when the total heat process results are combined. Black hair's value shifted downward and chroma left, and hue stayed either neutral or one color or it shifted counter clockwise on NCS color circle. Bleached hair's value shifted upward and chroma right, and hue stayed one color or shifted counter clockwise, but some exceptions. And it can be shown on NCS chart.

With the view of studying on the dual adsorption mechanism of acid dyes in connection with the structural difference of silk fibroin, silk fiber and silk fibroin memberane were used for equilibrium dyeing at $60^{\circ}C$, $70^{\circ}C$, $80^{\circ}C$ and pH 3.2, pH 5.0. The dyes used were C.I.Acid Orange 7 and C.I.Acid Red 88 introduced aromatic hydrocabon into Acid Orange 7. From the adsorption isotherm experiment, the total uptake of dyes can be described by Langmuir sorption and Nernst partition. Nernst partition. Nernst partition coefficient $K_1$ decrease of crystalline regions and orientation. The saturation value S of Acid Red 88 were large than total amino group contents and it was attributed it hydrophobic bond. On the other hand, the standard afficity and enthalpy were increased with the in crease of hydrophobic part of dyes. Both $k_1$ and $K_2$ were decreased with the increase of pH, but $k_2$ were more effected than $K_1$.

텐셀 혼방직물의 단점을 보완하면서 새로운 관능기를 도입하기 위해서는 캐티온화가 효과적이다. 이를 위해 인체 친화성이 있고 공해를 유발하지 않으며 반응이 용이한 키토산을 처리하였으며, 이에 의한 캐티 온화를 확인하기 위하여 음이온성 염료에 대한 염색성 변화를 살펴보았다. 먼저, 반응성 염료와의 염색성은 낮은 중성염의 농도에서도 키토산 처리 시료의 염색성이 우수하게 나타나 반응성 염료에 대한 염색 효율이 증대되었다. 이는 키토산의 아민기 도입으로 텐셀 혼방직물이 캐터온화되어 섬유에 치환된 친핵성기에 의해 반응성 염료에 대한 친화력이 향상됨으로서 중성이하의 조건에서도 염색성이 우수하게 나타난 것이다. 한편, 키토산 처리로 도입된 아민기의 작용으로 산성 염료와 친화력이 거의 없는 텐셀 혼방직물의 산성 염료에 대한 염색성이 크게 향상되었다. 또한 키토산 처리로 인하여 텐셀 혼방직물은 반응성 염료와의 친화력이 더 좋아졌고, 텐셀 단일직물의 경우 산성 염료와의 친화력이 더 좋아졌으며, 산성 염료보다 반응성 염료로 염색시 세탁견뢰도가 더 우수하였다.

In this study, we reviewed the color changes accompanying the laundering, wash fastness, and abrasion fastness of chitosan-treated cochineal-dyed fabrics. The treatment methods were classified into two based on the chitosan treatment: (Method 1): fabric specimens were pre-treated with chitosan prior to the dyeing procedure in salt form. (Method 2): the state of chitosan acid salt formation, coated on the yarn surface, was destroyed and neutralized prior to the dyeing process. The changes in the chitosan treatment methods bear more important meaning in view of the durability. In Method 1, it is highly likely for the chitosan to be detached from the surface by water during laundering since the chitosan is coated as acid salt state. In Method 2, the resistance d the chitosan to water was supposed to revive since the chitosan would return to its original state. Differences in the resistance of the chitosan treatrrent, however, according to the Method 1 and Method 2, fell short of our expectations. In Method 2, the wash fastness did not improve as we expected since the bond between the fibers comprising fabric specimens and the chitosan is not high even if the chitosan itself has high resistance to water.

A series of azo based disperse dyes were synthesized and applied to polyester(PET) fiber in supercritical carbon dioxide($ScCO_2$). Various aniline derivatives were used as diazo component and coupled with glycine ethylester or carbonic acid ethylester derivatives to give azo based disperse dyes. Depending on the various diazo substituents, absorption maxima varied from 415 to 529nm in acetone. Dyeing in $ScCO_2$ was carried out at $120^{\circ}C$ and 250bar pressure for 2hrs with 0.5% o.w.f. of dye concentration. Dyed PET fiber had excellent brightness and good light, washing and perspiration(acid/alkali) fastness properties.

스탠다드형 카네이션은 매스플라워로써 플라워디자인에 많이 이용되고 있으나 화색이 다양하지 못해 이용에 한계가 있다. 본 연구는 이용에 한계가 있는 스탠다드형 카네이션을 사용하여 최적 염색 상태의 처리 조건을 찾고 더 나아가 염색 카네이션의 화훼장식에서 활용도를 높이고자 수행하였다. 스탠다드형 카네이션 'White Liberty'를 이용하여 6가지 염료별로 4가지 화합물 처리에 따른 염색실험을 수행하였다. 실험은 염료 6가지 색[black(2012), lavender(2200), lime Green(2315), light blue(2386), christmas red(2506), yellow(2375) (Robert Koch Industries INC, USA)]과 4가지 화합물 처리(증류수, 4% 에탄올, 3% 설탕, 100mg·L^-1 구연산)를 사용하였다. 결과적으로 6가지 염료 모두 3% 설탕과 100mg·L^-1 구연산 처리가 빠른 염색과 염색정도에 우수한 경향을 나타냈다. 그러나 절화수명은 black과 lavender 염료를 제외한 나머지 염료에서 대조구(7일)와 유사한 경향을 보였다.

It is well recognized that the wicking of liquids in a textile fabric takes place mainly through a capillary system composed of the individual fibers. Considering typical dyeing stages, it is thought that a high dye uptake on the fabric probably depends on the wickability. Three kinds of barely water soluble ketones, acetophenone(A), 2-pentanone(2P) and 3-pentanone(3P) were separately dissolved in methanol(M) and then each was mixed with aqueous solution of C. I. Red Acid 114. Wicking heights of dyeing solutions were measured under such conditions that the effect of gravity was negligible. The result could be graphed as a series of straight lines having the form s = $kt^{1/2}$, where s was distance traveled by the solutions, t was time, and k was slope of the line. The surface tension(${\gamma}$) of the ketones had more signifcant effect on the wickability compared to the viscosity(${\eta}$) of them. The greater wickability resulted in the higher dye uptake on the fabric and the order of wickabilty was equal to that of the surface tension(${\gamma}$) and dye uptake on the fabric, A>3P>2P>M.
