Because cultural properties are a composite of various substances in addition to natural dyestuffs, an analysis based on the degradation of raw dyestuff materials should be performed first. This study selected Sophora japonica, Rheum undulatum, Gardenia jasminoides, and Phellodendron amurense among the commonly used yellow dyestuffs and performed an accelerated aging test on them. The results were then analyzed by evaluating color fastness according to the accelerated aging test of the dyestuffs. The color fastness of the dyestuffs selected above was excellent against ultraviolet (UV)- accelerated aging. However, after dry- and wet-accelerated aging, the colors tended to darken, and yellow and red tinges faded. Wet-accelerated aging produced more color changes than dry-accelerated aging, indicating poor color fastness. Rheum undulatum is the dyestuff with the best color fastness, and Gardenia jasminoides is the dyestuff with the worst color fastness. As the accelerated aging method and aging time were increased, the Rheum undulatum dyestuff showed insignificant changes. Therefore, the color fastness of Rheum undulatum outperforms that of the other dyestuffs selected here. Gardenia jasminoides showed almost no color changes resulting from UV-accelerated aging. However, color changes occurred in dry- and wet-accelerated aging, with wet-accelerated aging having the worst color fastness.

( Jeongkwan Roh ),( Hyun-jin Jo ) 한국목재공학회 2022 목재공학 Vol.50 No.1

After manufacturing the natural dyed actual size Hanji using 11 kinds of plant natural dyeing materials and 2 kinds of animal natural dyeing materials, the color characteristics and color change and color fastness after post-mordanting were compared and discussed. The hues of 13 types of natural dyed Hanji were black, PB, and RP, each with 1 type, YP with 3 types, and Y with 7 types. Among the natural dyeing materials, Chinese ink, indigo and Lac showed high color yield and color difference, and violet-root cromwell and gardenia seeds showed low color yield. The color fastness of Hanji dyed with turpentine diluted Ottchil, Pagoda tree seeds, Chinese ink and indigo was excellent, while that of gardenia seeds and violet-root cromwell were very poor. After post-mordanting of natural dyed Hanji with Al, Cu, and Fe mordants, the hue changes were show up the Alnus firma, clove, lac and cochineal. In addition, the color difference was very diverse and was overall the most biggest due to Fe mordant. After 72 hr. of UV irradiation on post-mordanting natural dyed Hanji, hue change was observed in 3 types and color fastness was improved in 8 types by post-mordanting. The Hue and color fastness are significantly different depending on the type of natural dying materials and post-mordants. Therefore, when dyeing Hanji with natural dyes, it is necessary to dye with sufficient knowledges and informations about the desired color and fastness.

This study aim to pursue eco-friendly fabric dyeing using food and beverage industry waste. The nylon fabrics were dyed with a combination of onion shell and coffee sludge extracts. The color characteristics and color fastness of the combination-dyed nylon fabrics were analyzed by color difference according to the combination dyeing sequence and the mordant(aluminum and iron). Results indicated that the nylon fabric color differed depending on the combination dyeing sequence. It was observed that the fabric dyed first with onion shell extract and then with coffee sludge extract sequentially produced a bright yellow-red color, while the fabric dyed with coffee sludge extract first and then with onion shell extract yielded a dull yellow color. The color of the nylon fabrics dyed with onion shell extract first and followed by coffee sludge extract was slightly different depending on the mordant type. However, no difference was observed in the color of nylon fabrics dyed with coffee sludge extract first and then with onion shells according to the mordant type. The color fastness to washing, dry cleaning, perspiration, and rubbing of the combination-dyed nylon fabrics with the onion shell and coffee sludge extracts showed 4 or 4–5 grade, while the color fastness to light showed 1 or 1–2 grade.

Since ancient, henna (Lawsonia inermis) is used as colorants and drugs. In this study, effects of fastness, hair coating and hair protection were evaluated on decolored hair pieces after henna coloring and 30 times shampooing. No chemicals treated female hairs as sample were collected and divided in 6 pieces. 5 Hair pieces of them were bleached with 6% hydrogen peroxide, and 4 pieces of bleached hairs were colored with oxidizing colorant (OcH), henna orange powder (HnH), henna orange powder with acetic acid (HnH-A) and henna orange powder with natrium hydroxide (HnH-B). Cromacity (Lightness; L*, redness; a*, yellowness; b*) of hair pieces, thickness of hair cuticles and hair shaft and tensile strength of hair shaft were measured, and morphological change of cuticles was observed by SEM before and after shampooing. As the results, color of normal and 8 level of ICS bleached hair were not changed before and after shampooing. The orange color of OcH was the darkest before shampooing but was the lightest after shampooing in all of colored hair pieces. And the change of L*, a* and b* was smaller in HnH-B than in the other colored hair pieces. Not only thickness of hair shaft and cuticles in OcH was the thinnest but also tensile strength was the weakest in all of colored groups. In contrast to the oxidizing colored hair pieces, HnH-B was revealed the thick hair shaft and high tensile strength. More damage of hair cuticles and exposure of cortex were shown on OcH than on 3 different henna colored hair shafts by observation of morphological change. In conclusion, henna orange powder under alkali condition may be better effects of coloring, fastness, hair coating and protection than that of oxidizing colorant. And these excellent effects may be an action of lawsone and luteolin that are constituents of henna pigments.

Most conservation papers used for the management of domestic records are mainly imported products, which are made of chemical, mechanical, and recycled pulps with various types of organic and inorganic additives. In this study, different colors as per their importance and conservation period were applied to machine-made Hanji papers used for the long-term storage of the public records. In addition, the stabilities of the different colors from the selected pigments for conservation paper products were analyzed. Additionally, the optimal conditions of adding pigments and additives on colored Hanji paper made from Dak pulp (80%) and SwBKP (20%) for use in conservation were examined. As a result, yellow, blue, white and black pigments showed low color transferability, while gray colored Hanji paper made from mixing white and black pigments showed excellent color fastness. Meanwhile, the colored Hanji paper made with red pigments showed high transferability and poor color fastness. Hanji paper without any pigments also showed transferability and color fastness, but inferior to that produced with red pigments. Therefore, the study concludes by affirming that the mixed compositions, which consist of yellow, blue and black, with no red pigment but high whiteness and low chrome would be ideal on the machine-made Hanji paper for the long-term storage of public records.

Recently, the safety of workers in industries has emerged as an important issue. In particular, when the workers are exposed to gaseous or liquid acids, it can lead to a seriousproblem to the human body. In the previous studies, we investigated the applicationof halochromic dyes on a nylon fabric for an acid-detecting textile chemosensor. In thisstudy, bromocresol green was selected as a pH-indicating dye and its dyeing, fastness, andacid-sensing properties on a wool woven fabric were investigated. Bromocresol green in anaqueous solution of pH 2-4 showed maximum absorption at 444 nm with yellow color,whereas the maximum absorption changed to 616 nm showing blue color in a solution ofpH 6 and over. Color yields (K/S) of bromocresol green on wool were dependent on thedyebath pH. The wool fabric showed greenish blue color when dyed at pH 4-7. The color ofwool dyed at pH 3 was yellowish green, and the color at pH 2 was olive. The percentexhaustion of bromocresol green on wool increased with decreasing the dyebath pH, anda high exhaustion value of 98-99% could be obtained at pH 2-4. When the control sample,dyed at pH 4, was immersed in a solution of pH 3.5-4, its original greenish blue color wasmaintained. When immersed in a solution of pH 2-3, the color changed into olive withexhibiting a big color difference. The soaping process did not affect the color fastness. Thewash and dry cleaning fastness of the wool fabric dyed at pH 3-5 was very good. The dryand wet rubbing fastness were excellent.

In this study, the dyeing properties of Phellodendron amurense on cotton and silk fabrics were evaluated to establish a scientific database of dyeing methods using natural dyes with the ultimate aim of facilitating the practical use of these dyes. The optimal thickener and dyeing concentrations depending on the thickener type were identified when dyeing with P. amurense, and the fabric color, color fastness, and antibiosis were examined for various thickeners, fabrics, and mordants. The results were as follows.: The optimal concentrations of thickeners when dyeing on cotton and silk fabrics were CMC 3% (w/w), Mayprogum 7% (w/w), and Indalka 9% (w/w). The optimal concentration of P. amurense was 25% (w/w), irrespective of the type of thickener. To maintain the hue unique to P. amurense, thickening with Mayprogum or Indalka and mordanting with Al was effective for cotton, while thickening with Mayprogum or Indalka and mordanting with Al or thickening with CMC and mordanting with gallnut was effective for silk. The dry-cleaning fastness and abrasion resistance of cotton fabrics dyed with P. amurense were excellent at the 4-5 level. Gallnut was effective for washing fastness and perspiration fastness against color degradation, and FFC was effective for light fastness. The washing fastness, dry-cleaning fastness, abrasion resistance, and perspiration fastness of silk fabrics dyed with P. amurense were excellent at level 4, except for washing and perspiration fastness, and FFC was effective for the improvement of light fastness. Dyeing cotton and silk fabrics with P. amurense thus yielded antibiosis and excellent washing fastness.

An analysis of the components of clay mineral before and after coloration (XRF) showed that the ele-mants involved in coloration are Fe, Cr, and Ni Fe accounts for 65% of coloring conponents on dyed fa-bric: in addition, Cr and Ni also affect coloring. The optimal coloration condition was to repeat the process of immersing the cotton fabric in 80℃ slurry of 8g of clay mineral to 1g cotton for 60 minutes, dry it for 24 hours and rinse three times. Especially, as the repetition of coloration increased, the (K/S)440 value of sample A increased from 1.0 to 2.5, and sample B increased from 1.0 to 1.6. The effect of the repeated process on coloration was significant: consequently, the rinsing and drying process were important to dec-rease the coloration level. It also showed excellent resuIts in regard to color fastness to washing, light, rub-bing, perspiration, and antibiotic effect.
