In this research, we have examined dyeability of Lyocell/Silk blend yarn according to blend rate of silk in 10, 30 and 50% which offers more elegant luster and handle, more superior strength, and easier care than cotton-silket embroidery yarn does. Also, we have examined not only the dyed Lyocell/Silk blend yarn`s tensile strength and elongation, but also colorfastness to washing, abrasion, perspiration, and light. In addition to that, by using dyed Lyocell/Silk blend yarn, we tried to embroider on cotton, knit, and satin to examine the potential use as a new embroidery yarn. The dyeing process of Lyocell/Silk blend yarn with reactive dye was carried out condition in 60℃ for dyeing temperature, 60 min time, and pH 10.8-11.0. Dyeability of dyed blend yarn evaluated by K/S was estimated form Kubelka-Munk which is based on reflection value of maximzed absorption wavelength. Through this research, we have obtained the results as follow. Lyocell/Silk blend yarn was possible dye with reactive dye and one bath and optimum condition in which was pH 10.8~11.0 in 60℃ for 60 min. Dyed Lyocell/Silk blend yarn has shown high dyeability (10~20 in K/S), and as silk blend rate increased, the dyeability was decreased. When the concentration of dye increased, the dyeability was increased as well. Despite of change in dyeing temperature, there was almost no difference in dyeability. Also, dyeability became higher in alkaline bath (pH 10.8~11.0) than in acidic dyeing bath. Lyocell/Silk blend dyed yarn`s tensile strength was much more excellent than cotton silket embroidery yarn`s. Also, as silk blend rate increased, the tensile strength was increased as well. Whereas, in case of elongation, it was increased when silk contents increased. Colorfastness to washing, perspiration, and abrasion of Lyocell/Silk blend yarn showed excellent grade of 4-5 grades. The grade of the colorfastness to light showed more than 4 grade as well. We have embroidered on various fabrics such as cotton, knit, and satin by using dyed Lyocell/Silk blend yarn, and have found that the dyed Lyocell/Silk blend yarn can be used as a practical, aesthetic high quality embroidery yarn.

The dyeing of meta-aramids (m-aramids) has conventionally been difficult due to their rigid molecular and dense crystalline structure that results from hydrogen bonding, although various dyeing techniques have been applied in the past to improve their dyeability. In this study, m-aramid nanofibers were fabricated by electrospinning with a 15 wt% m-aramid/DMAc solution, followed by either water or thermal treatment. The thermal stability and crystalline structure of the m-aramid nanofibers were investigated by thermogravimetry (TGA) and X-ray diffractometry (XRD), respectively. The effects of the water and thermal treatments on the dyeability of m-aramid nanofibers containing either pigment or dye were compared based on the K/S value and color difference. The results indicated that the use of dye is preferable to the use of pigment to improve the color depth of m-aramid nanofibers.

김춘일(Chun-il Kim) 제주학회 2016 濟州島硏究 Vol.46 No.-

제주는 천혜의 자연환경과 독특한 문화 자원을 토대로 세계적인 관광제주로 변화하고 있다. 또한 2014년 1월, 전국 최초로 말(馬)산업 특구로 지정되면서 말산업이 국민의 삶의 질을 향상시키는 복합 문회산업으로의 발전을 통해 농촌 경제 활성화와 청소년 인성 함양, 레저문화 발달 등의 효과가 기대되는 성장 잠재력과 부가가치가 높은 산업으로 인식되고 있어 관광산업과 더불어 제주의 대표산업으로 부각되고 있다. 말과 관련한 다양한 콘텐츠 개발과 활성화 방안의 모색을 통해 관광산업과 연계하여 발전시키고자 말을 소재로 한 문화관광상품 개발에 대한 연구가 시도되고 있으나 아직은 매우 부족한 실정이다. 이에 본 연구는 제주도에 서식하고 있는 말의 도축 과정에서 발생하는 부산물인 말총(Horse hair)을 천연의 소재로서 가치를 재발견하고 말총을 활용한 문화관광상품을 개발하기 위해 제주산 버진(Virgin)말총과 탈색(Bleach) 말총에 빨강, 노량, 파랑으로 각각 산성염모제를 도포하여 염색된 말총의 염색성을 색차계를 사용하여 명도(Lightness, L*), 적색도(Redness, a*), 황색도(Yellowness, b*), 색채(color difference, △E) 값을 측정하였다. 자연 상태로 각각 분리된 검정, 노랑, 흰색계열의 말총과 세 가지 계열의 말총을 탈색 처리한 말총 모두 염색성을 나타내었다. 특히 노랑, 흰색 계열의 말총은 버진(Virgin) 말총과 탈색 처리한 말총에서 모두 높은 염색성을 나타내어 버려지는 말총을 다양하게 활용하여 제주도의 문화관광상품을 개발하는데 충분한 기능성이 있을 것으로 판단된다. 향후 색상의 안정화를 위한 첨가제, 광태, 내구성, 향을 보완 할 수 있는 연구가 필요하다고 사료된다. Based on the natural environmental conditions and unique cultural resources, Jeju has become a global tourist attraction. In January 2014, Jeju was designated as the special horse industry zone for the first time in the nation. Therefore, with its development into the complex cultural industry to improve people s quality of life, the industry has been recognized as the me with growth potential and high added-value, which is expected to activate agricultural economy, raise adolescents personality, and develop leisure culture has been recognized as the me with growth potential and high added-value. Therefore, along with tourism, the horse industry has emerged as me of representative industries in Jeju. In order to find a way of developing and activating various contents relating to horses and grow the horse industry in association with tourism, research has been conducted to develop cultural tourist products based on the theme of horses. However, there is still a lack of research. Therefore, to rediscover the value of horse hair, which is a by-product of the butchery process of horses living in Jeju, as a natural subject and to develop cultural tourist products using horse hair, this study applied an acidic hairdye with red, yellow, and blue each to Jeju Virgin horse hair and Bleach horse hair, and measured the Lightness (L*), Redness (a*), and Yellowness (b*), and color difference (△E) values of the dyed horse hairs with the use of color-difference meter to look into their dyeability. Black, yellow, and white horse hairs which are separated each as they are, and three types of bleached horse hairs which have different colors were found to have dyeability. In particular, in the case of yellow and white horse hairs, virgin horse hairs and bleached horse hairs showed high dyeability. Therefore, it is judged that horse hairs, mostly thrown away, have a great deal of potential for developing cultural tourist products in Jeju Island. In the future, it will be necessary to research improvements in additives for color stability, polishing, durability, and fragrance.

박수진,진중성,최경은 한국섬유공학회 2001 한국섬유공학회지 Vol.38 No.5

The effect of corona discharge on polyethylene (PE) film was studied in terms of surface functionality and surface energetics of the film surfaces, resulting in improving the dyeability. The introduction of functional group could be confirmed by ESCA. Owens-Wendt and Wu's models using a geometric means were studied to analyze the surface free energy of corona-treated film. As a result, the corona-treated PE films led to an increase in surface free energy, mainly due to the increase of its specific (or polar) component. From the acid-base component point of view, it was found that the corona-treated PE film played an important role in improving the dyeability. A direct linear relationship is shown between specific component of surface free energy and the K/S value for this work.

DLP 3D Printed Textile의 유연성 향상을 위한 모델링 디자인 및 염색성 평가

심연제,김현진,김혜림 한국의류학회 2022 한국의류학회지 Vol.46 No.3

3D printing has been considered a key technology, leading the fourth industrial revolution. However, 3D printed textile still has a lot of limitations to overcome before it can be adopted as a clothing material in terms of design, flexibility and dyeability. This study aims to provide modeling design for imparting the flexibility and post-dyeing process for 3D printed textiles. The modeling types were designed to test the flexibility of 3D printed textiles. The post-dyeing process was evaluated through dye absorption depending on the resin and modeling types, respectively. The results were as follows: two types of modeling (Modeling A and B) were designed with a ring structure to test the flexibility of the 3D printed textiles. The 3D printed textiles with ringbased structure Modeling A had flexibility regardless of the hardness of resin types. In the dyeability test, softening resin (S-Resin) and hardening resin (H-Resin) were found to have good dyeability with acid dye and direct dye, respectively. The condition of S-Resin with acid dye and H-Resin with direct dye was controlled by dye absorption rate.

문정원,이선희,이정순 한국섬유공학회 2023 Fibers and polymers Vol.24 No.5

In this study, natural dyeing studies using turmeric and lac were conducted to test their respective utility as yellow and reddye in 3D-printed thermoplastic polyurethane material. For this purpose, turmeric and lac were first extracted with distilledwater to analyze their color characteristics. Next, the extracted turmeric and lac dyes were dyed in 3D-printed thermoplasticpolyurethane material under different dyeing conditions to examine their dyeability. The dyed thermoplastic polyurethanematerial was also investigated in terms of its color fastness to sunlight, washing, and rubbing. The experimental resultsconfirmed that the turmeric extract was composed of three mixtures of dimethoxycurcumin, bis-dimethoxycurcumin, andcurcumin, and that the lac extract was composed of two components: laccaic acids A and laccaic acids C. Thermoplasticpolyurethane material dyed with turmeric dye showed Y-series, while thermoplastic polyurethane material dyed with Lacdye showed YR-series. Both dyes showed the Lamgmuir-type isothermal adsorption curve in which the amount of dyeingno longer increased beyond a certain level of initial dye concentration and dyeing time. Under the experimental conditionsof this study, in the case of turmeric dye, the optimum dyeing conditions were determined to be 20% concentration, 60 °Ctemperature, and 20 min. Meanwhile, the optimal dyeing conditions for lac dye were determined to be 60% concentration,90 °C temperature, and 30 min. Thermoplastic polyurethane material was dyed under each optimal dyeing condition, and asa result of measuring the light fastness, washing fastness, and rubbing fastness of the resulting material, relatively high colorfastness was obtained. The results showed that a high dyeing amount and color fastness were obtained solely

In this study, the pigment properties of extracts were analyzed using dried Aronia melanocarpa fruit as ethanol and distilled water adjusted to pH 3, 5, 7 as solvent. Additionally, the effects of extraction and dyeing conditions on the dyeability of silk and cotton fabrics were evaluated. Ultraviolet and visible absorption spectra and FT-IR measurements of the Aaronia extract showed the presence of anthocyanins, tannins, and flavonoids. This means that distilled water extract and ethanol extract of Aronia fruit comprise many sulfated components such as natural phenols. The color of the fabric dyed with Aronia melanocarpa fruit distilled water extract before decompression concentration was YR series, which was almost reddish purple. The color of the fabric dyed with extract after decompression concentration was Y series, which was almost brown. The lower the pH of distilled water extraction, the higher the redness of the dyed fabric, and the higher the dyeability. As the concentration of the extract increased, the dyeing amount increased and the dyeing temperature was relatively high at the dye bath temperature of 80℃ and dyeing time of 60 minutes. Even though color fastness to the light was unsatisfactory, washing, fastness to rubbing, and perspiration showed relatively high grade.

김애순 한국의류학회 2000 한국의류학회지 Vol.24 No.5

Historically, dyed textiles were symbols of status and, because of their expense, reserved only for people of wealth and specalist. Early dye sources probably included plant, animal and mineral extracts. As synthetic dyes have been developed, beginning with synthetic indigo in 1897, reliance on natural dye sources diminished. But renewed interest in natural dyes is fueled by a pro-environment consumer aware of the ecological liabilities of the dye industry. Han Jee was imported from China where it was influenced to period of the three kingdoms(Silla, Baekje, Kokuryo). After that, Han Jee was used for paper in old Korea for long time before paper was came with civilization. In this paper, dyeing of Han Jee with loess were investigated according to dyeing temperature, dyeing time, loess concentration, and effects of additives. As a results, λ_max of Han Jee dyed by loess was 710nm. ΔE values of Han Jee increased by loess concentration, dyeing time, dyeing temperature. Dyeing with additives treatment increaed dyeability. Especially, Han Jee treated with aluminium acetate shows the largest dyeability of the Han Jee. The Han Jee dyed loess had very good lightfastness.

Transactions : Dyeability and Colorfastness of Knitted Fabrics with Natural Dye Pinux(TM) (Part 1)

( Geom Bong Wang ),( Kyung Hun Song ) 한국의류학회 2011 한국의류학회지 Vol.35 No.12

Dyeability and colorfastness of the blended knits of cotton/rayon (40/60; C/R) and wool/tencel (10/90; W/T) are examined using the natural dyestuff (Pinux (TM)) manufactured from Pinus radiata pine bark extract. In addition, pre-treatments (such as bleaching, mercerization and cationization) are performed to improve dyeability and colorfastness. The Pinux(TM) powder dyestuffs produced by Pinux Co., Ltd. are used as dyestuffs and their properties are examined for dyeing concentration (0.5-2% (owb)), dyeing time (30-120 minutes) and dyeing temperature (30-90℃). Dyeability is evaluated with K/S value at 400nm, which is the maximum absorption wavelength for Pinux(TM). The results show the dyeability of W/T sample containing protein fiber with Pinux(TM) is superior to all cellulose fiber C/R. A concentration of dyestuff greater than 1.5% (owb), dyeing time 120 minutes and dyeing temperature of 90℃ are the most optimized conditions. It shows that the dyeability of C/R and W/T samples are high in the condition of an acid-dyeing bath and that dyeability highly declined in alkaline bath due to the instability of the proanthocyanidin pigment. After analyzing the effect of bleaching, mercerizing and cationizing (as pre-treatments on dyeability) it was concluded that the dyeability of the C/R sample was enhanced by mercerization but no significant effect by cationization. However, the simultaneous treatment of cationizing and dyeing resulted in far improved dyeability compared to dyeing after cationizing pre-treatment. As for the W/T sample, the effect of cationization was more prominent than the C/R sample. Colorfastness to color changes in the control W/T sample was higher than that of C/R`s level 1-2, and it increased to Level 2 when bleaching pre-treatment was given and when a simultaneous cationizing treatment was adopted to the dyeing process. Colorfastness to light in W/T control sample resulted in Level 3 and further increased to an excellent Level of 4 with bleaching and simultaneous cationizing during dyeing process.

산화아연 함유 기능성 리오셀의 천연염색 상용화 가능성에 관한 연구

김소진,최경미 한국패션비즈니스학회 2022 패션 비즈니스 Vol.26 No.4

After the corona pandemic, when consumers choose clothes, the issue of sustainability has become a more important selection criterion. The eco-friendly functional fiber used in the study is a smartcell, which has functions such as UV protection, decomposition of harmful substances, deodorization, antibacterial and biodegradation. This eco-friendly functional fiber was dyed using five kinds of natural dyes to examine the color change according to dyeability and dyeing conditions. As natural dyes, gardenia, turmeric, sappan wood, lac, and indigo were used. For comparison with smartcell, rayon, a cellulose regenerated fiber, and wool fiber, a protein fiber, were dyed under the same conditions to compare dyeability and color. The study results are as follows. It was found that smartcell had superior dyeability compared to rayon and wool in gardenia dye and showed lower dyeability than wool when dyeing turmeric, sappan wood, and lac dyes, but showed superior or similar dyeability than rayon. In case of indigo dyeing, the dyeability of smartcell was the best when dyed once, but it was found that smartcell had a lower effect on repeated dyeing compared to wool or rayon. Therefore, smartcell has superior dyeability compared to rayon fiber in gardenia, turmeric, sappan wood, and lac dyeing, and in case of indigo dyeing, it is suitable for light dyeing. When smartcell is produced as textile fashion products, natural dyeing is actively introduced and commercialized, and it is hoped that this study can be a reference material.
