To develope natural dyeing materials from the unused plant materials, we had several dyeing experiments to investigate the optimum conditions of dyeing fabrics with the waste grape juice. Dyeing experiments were done under different dyeing conditions of dyeing time, dyeing temperature, pH and concentration of dyebath and mordants which were treated after dyeing. Experimental fabrics were silk, cotton, ramie and hemp. Color difference(${\Delta}E$) and Munsell's HV/C of the dyed fabrics and color fastness of silk dyed fabrics to dry cleaning, washing, rubbing, perspiration and light were measured. The color differences of dyed experimental fabrics were very slightly increased with dyeing time and the color of dyed silk was light purple and the cotton, ramie and hemp was light red purple. The color differences of dyed experimental fabrics were decreased and the color became lighter with dyeing temperature increased. The color differences of dyed experimental fabrics were decreased and the color changed from light purple to blue with the pH of dyebath increased. The color differences of dyed experimental fabrics were slightly increased with the concentration of dyebath increased. The color of dyed fabric changed with the mordant treatment and were different among the experimental fabrics. On the whole, blue tone increased with the Al and Fe mordant and green tone increased with the Cu mordant. The color fastness of dyed silk fabrics to light, washing (change) and perspiration (change) was bad and color fastness to dry cleaning and rubbing were good.
The dyeing with loess has been studied. Two kinds of cotton fabrics having different thickness and density were dyed in loess paste bath. The color differences of the fabrics which were dyed repeatedly.five times were not significant. The dyeing of cotton fabrics with loess was not exactly reproducible, but dyeability of the cotton fabrics of high density was better than that of low density. Loess on the dye6 fabrics was physically jammed between the fibers in the form of the fine particles. The cotton fabrics dyed with loess have good light fastness, but their laundering fastness and abrasion fastness were not good. An aftertreatment was carried out by using the extracted solution from acorn or persimon, and FeSO4 lot improving fastness. When the dyed fabrics was after-treated with FeSO4, the laundering fastness and wet abrasion fastness were improved extremely.
Recently, it has been reported that chemical hair coloring can cause allergic reactions, the toxicity issue of chemical hair color was issued. Therefore, there is an increasing interest in the hair coloration technique using non-toxic and bio-compatible hair color gotten from natural resource. In this study, the possibility using fermented Indigo as natural hair coloring agent was investigated. Bleached hair samples were dyed using Indigo, and the effect of dyeing frequency, the physical change after dyeing, color, surface and cross-section characteristics, and tensile property were also studied. In addition, the protection property of cationic detergent finishing on damaged hair samples were also studied. The following conclusions are made; 1. While bleached hair samples with low value showed the negligible effect of repeated dyeing, bleached hair samples with high value showed the good effect of repeated dyeing. 2. Hair sample dyed with Indigo showed a high light-fastness, however, tensile strength and elongation showed very low values (high damage on hair sample). 3. Cationic detergent finishing did not affect on the colorfastness because of decoloration after dyeing, however, it increased the smoothness of hair sample, and therefore, can use as protectant of damaged hair. 4. Hair scale was damaged after dyeing. It seemed that the alkali, potassium carbonate, increased pH of dyeing bath to 11, as a result, the hair was swollen, weaken, and dissolved on the prolonged dyeing time. Dyed hair sample became stiff and fine. 5. The color difference was 4.62 (a high fastness value) in the test of sunlight exposure, shampoo, cationic detergent finishing, and acid perspiration fastness.
The natural dyeing of fabrics with persimmon juice(astringent persimmon, sweet persimmon, astringent and sweet persimmon mix) was investigated. After dyeing of cotton and silk fabrics with persimmon juice, we evaluated the dyeability of persimmon juice, the observation of fabric surface with high magnification video microscope, physical properties and color fastness with the conditions of repeating times of dyeing and variables of mordants. The results obtained from this study were as follows: The fabrics dyed with astringent persimmon have shown the highest color difference, while the fabrics dyed with sweet persimmon and the fabrics dyed with astringent and sweet persimmon mix have shown similar color differences. With the increase of repeating times of dyeing, the brightness of fabric decreased. However, $a^*$ value increased gradually, so that it became dark brown color. The $a^*$ and $b^*$ values of dyed fabrics with Fe-mordant have dropped significantly, so that they have shown achromatic colors. But the fabrics treated with other mordants have shown yellowish brown colors. On the surface of the fabrics, threads were bonded together by the viscosity of persimmon juice. Regardless of the types of persimmon juice, stiffness was increased after dying, while crease resistance was decreased. The water repellency of silk fabrics were improved than cotton fabrics after dyeing with sweet persimmon juice, but in case of cotton, it hasn't changed. Washing fastness was improved with the EM(Effective Microorganism)-fermented liquid treatment, and rubbing fastness of two fabrics was better in dry condition than in wet condition.
This study conducted a research on burn-out printing convergence technology for cellulose blend knit fabrics. Printing technology, which forms color pattern on the fabric, can be generally classified into four according to printer or printing method, e.g. screen printing, roller printing, rotary printing, digital printing. However, these printing methods are flat in design or pattern, which have limitation to overcome monotonousness of fabric, so that recently burn-out process method, which expresses three-dimensional pattern effect by treating chemical on the surface of fabric as the method to appeal its esthetics to the customers. Particularly, in case of cellulose/polyester composite material, first, it is proceeded in 2 processes, by dyeing cellulose or polyester fabric and burning out cellulose fabric, in this process, due to pollution caused by disperse dye migration, color of polyester fabric part could be discolored, which has high falt risk. This research considered coloring burn-out technique, which simultaneously proceed dyeing and burn-out by reducing dyeing and burn-out process to 1 stage, which were proceeded in 2 stages previously. As the research result, it was confirmed that reasonable depth of roller was 0.04~0.06mm in roller printing process, heat treatment condition of burn-out far-infrared radiation was $185^{\circ}C{\times}30m/min$. Color fastness to washing was confirmed to be 4-5 grade, color fastness to rubbing, 3-4 grade, color fastness to light, 4 grade. Also, it was confirmed that energy reduction effect appeared 38.19%, in case of energy cost per yard compared to the existing production, also, 19.74%, in case of production cost.
Effect of disperse dyeing on flame retardant finishing of PET fabrics via UV curing using three UV curable phosphorous-containing methacrylates and ammonium polyphosphate(APP) was investigated. The dye fixation and flame retardancy of PET fabrics did not change significantly with excellent durability to five laundering cycles irrespective of the dyeing and finishing sequence. However, the flame retardancy of Pekoflam-treated fabrics was lower than that of the UV treated and decreased substantially when heat treatment was carried out before the dyeing. The dyeability of the flame-retardant PET fabrics was not affected in the case of UV curing of the methacrylates alone. However, UV finishing after the dyeing caused significant decrease in K/S and ${\Delta}E$ due to changed refraction and inherent color of surface coating of the UV curable monomers and APP. Whereas the heat treatment with Pekoflam decreased both color fastness to laundering and sublimation, surprisingly the UV finish of PET fabrics before and after the dyeing increased the color fastness probably resulting from the presence of photopolymerized surface layer on the fabrics.
The purpose of this study was to investigate dyeing properties of silk and wool fabric by Cassia tora extracts according to the conditions such as extraction(temperature time) dyeing(temperature time) condition kinds of mordants temperature of mordanting. The color fastness of laundering irradiation were examined. The results were as follows: The wavelength of maximum absorpthion by extracts appeared at 201, 277, 382nm in UV-Vis spectrum. Absorbance of extracts were increased with temperature and time. The extraction efficiency of Cassia tora was determined as $95^\circ{C}$ of extraction temperature 120 minutes of extraction time. Silk fabric had highest K/S value when dyeing for 90min at $40^\circ{C}$. Wool fabric had highest K/S value when dyeing for 60min at $80^\circ{C}$. Surface color of silk and wool fabric dyed with Cassia tora extracts was 3,9Y and 0.4Y but it was changed from 9.3YR to 7,4Y and from 9.4YR to 5Y by mordants. The fabrics of mordanted by metal ion dyed the depth of color. Laundering and irradiation fastness of mordanted fabrics were improved as compared with nonmordanted fabrics.
This study examines the mordanting effect and multi functional properties of silk fabrics dyed with onion shell extracts that were mordanted with gallnut. The contents of this study are as follows. First, the optimum dyeing conditions were investigated by measuring the K/S value that depended the on dyeing conditions when silk fabrics were dyed with onion shell extracts. Second, the color, brightness, and chroma differences that appear after mordanting with gallnut were investigated by measuring the K/S and Munsell value. Third, the color fastness and antimicrobial activity were measured. When silk fabrics were dyed with onion shell extracts, the optimum dyeing conditions were a dyeing temperature of $70^{\circ}C$, a dyeing concentration of 160%, and a dyeing of time 30min. After mordanting with gallnut extracts, the K/S value increased remarkably and was larger in pre-mordanting than post-mordanting. The H value displayed yellow-red in all cases of pre and post mordanting. However, the H value was more reddish in the order of non-mordanting
In this research, the curly dock was used in the process of dyeing for fabrics of the inner wear & the patient wear. Since the curly dock has a pharmacological effect on dermatosis, this study focused on the variety of color and functions of the inner wear fabrics & patient wear fabrics to make the best use of the pharmacological effect of curly dock. With regards to giving a variety of colors and functions in the inner wear, patient wear fabrics, the curly dock dye was used in each treatment conditions on the cotton & silk fabrics. After dyeing, the dyeability, color change, light fastness, washing fastness, perspiration fastness, antibiosis, far infrared emissivity and emission power were evaluated. The evaluation results are as follows; The dyeablity increased from repeated dyeing and, by using the mordant, variety of colors such as skin, mustard, greyish-brown and dark earth colors were conformed to the naked eye. Fe mordant was better than Al on the lightfastness and the washing fastness. The repeated dyeing was found out to have less effect on neither lightfastness nor washing fastness. Both silk and cotton fabrics were graded $3{\sim}4$, since their degree of degradation appeared to be the same in alkali perspiration and acidic perspiration. In the case of silk fabrics mordanted by Al, the rate of declining in both Staphylococcus aureus ATCC 6538 and Klebsiella pneumonia ATCC 4352 were 99.9%. In addition, the antibiosis was enhanced when the mordant was used. The far infrared was 86.6% of emissivity, $3.34{\times}10^2\;W/m^2{\cdot}{\mu}m$ emission power.
Optical behaviors and dyeing properties of color solution extracted from arrowroot leaves were investigated. The wavelength of maximum absorption of the color solution appeared at 268 and 320 nm, respectively. The amount of colors extracted was increased with extracting temperature and time. Spectra of color solution are shifted to longer wavelength at higher pH values, and shifted to shorter wavelength by irradiation for 2 hrs. Remaining ratio of colors by irradiation decreased with increasing alkalinity of color solution. Degree of exhaustion on the silk fabrics was related to the concentration and pH of dyebath. Surface color of dyed fabrics, lightfastness and wash-fastness were variously according to mordant used. Hot water resistance and drycleaning fastness of dyed silk fabrics by treatment of mordants were all within commercially acceptable limits.
