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.

Shaoya Hao,Qin Chen,Tao Zhao 한국섬유공학회 2019 Fibers and polymers Vol.20 No.7

In this study, the influences of the temperature and pH value on the breaking strength of Polyoxymethylene fibers(POM) are studied. POM fibers and regular polyester (PET) fibers are dyed with twenty-three regular disperse dyes, and theirdyeing properties are compared by measuring their dyeing uptake, K/S values and colorfastness. Based on the dyesexamination, POM has relatively lower dyeability than PET in terms of dye uptake and colorfastness. 15 out of twenty-threedisperse dyes on POM fibers have exhaustion higher than 75 % at 1 % o.w.f, whereas 22 disperse dyes on PET fibers hadexhaustion higher 90 % at 1 % o.w.f. Further study shows that the apparent shade depth (K/S) on POM is three times higherthan that on PET when their dye uptake is the same. The dying heat-rate curve of 9 disperse dyes (exhaustion over 70 %) onPOM fibers is also investigated.

벤조피란계 천연색소의 금속착염을 이용한 흑색 모발염색

정찬희,신윤숙,유동일 한국섬유공학회 2017 한국섬유공학회지 Vol.54 No.6

As the substitute of synthetic black hair coloring materials, we focused on benzopyran natural colorants as known as a pleochroism dyes which forms coordination complexes with metal ion. We selected sappan wood(brazilin) and logwood(hematoxyilin) to represent benzopyran-based colorants. Ferrous sulfate and the extract of alder tree or tannic acid were used for mordanting. Wool was applied as the reference for hair dyeing to improve the color properties. By using both of metallic- and bio-mordants, we obtained the dyed hair of deep black color and high color strength with less than 8% of the surface reflectance. Light colorfastness of the dyed hair was relatively good and the rating 4-5 was obtained up to 100 hrs. And the rating to washing of the dyed hair was maintained 5 up to 30 cycles for the evaluation of colorfastness.

면섬유에 대한 홍차색소의 염색성

신윤숙,서명희 한국의류학회 2000 한국의류학회지 Vol.24 No.1

The colorants from black tea infusion were applied to cotton fabric. Dyeing properties were investigated in terms of dye uptakes at various dyeing conditions and the effect of mordants on color change and colorfastness. Cotton showed low affinity to black tea colorants. Effect of mordants on dye uptake was not significant except Sn. Irrespective of mordant type, color of cotton dyed with black tea colorants was brownish and colorfastness was generally good. In order to improve dye uptake, cotton was cationized by treating with Cationon UKt (tertiary ammonium salt) and chitosan. Dye uptake of cotton was remarkably increased by cationizing. Cationon UK was more effective than chitosan.

Dyeability and Colorfastness of Knitted Fabrics with Natural Dye PinuxTM (Part 2) -Improvement of Colorfastness Using Cationizing Agent and Smectite-

( Jong Sun Jung ),( Kyung Hun Song ) 한국의류학회 2012 한국의류학회지 Vol.36 No.12

This study examines the possibilities to improve natural dyestuff`s (PinuxTM) dyeability and colorfastness for C/R (Cotton/Rayon (40/60)) and W/T (Wool/Tencel (10/90)) knitted fabrics in cationizing and smectiting for pre-treatment, simultaneous-treatment and post-treatment process sequences; as well as various other treatment methods. The sample dyeability showed the strongest K/S value in the order of smectite (S) < cationization + smectite (C+S) < cationization (C); however, the K/S value showed a low level in the simultaneoustreatment method of smectite. Colorfastness to washing improved in the order of C < C+S < S, and after thes mectite post-treatment process, C/R improved from Grade 1 to Grade 4 and W/T improved from Grade 1-2 to Grade 4. Colorfastness to perspiration generally improved in the same order as the colorfastness to washing and after the smectite post-treatment process C/R, W/T sample`s acidic and alkaline colorfastness to perspiration improved greatly. As for the colorfastness to rubbing, the addition of smectite in the simultaneous-treatment and post-treatment processes resulted in improved wet-colorfastness; however, smectite showed less effect on the colorfastness to light compared to other colorfastness ratings.

연구논문 : 소목(Caesalpinia sappan L.) 열수 추출물을 이용한 모발염색 및 견뢰도 분석

김수영 ( Su Young Kim ),정원지 ( Won Ji Jung ),나명석 ( Myung Suk Na ) 한국미용학회 2013 한국미용학회지 Vol.19 No.4

본 연구는 모발 천연 염료 개발을 위한 기초 연구를 위해 식물인 소목에서 염료를 열수 추출하여 탈색모발에 처리온도와 시간 조건을 달리하여 염색을 실시한 후 염색 모발에 대한 염색성과 염착량, 견뢰도를 조사하여 다음과 같은 결론을 얻었다. 소목 열수 추출물은 탈색 모발에 염색할 경우 처리 온도와 시간 변화에 관계없이 모두 붉은 색 계열로 염색되는 염색성을 보였다. 특히 모발 염색성은 30oC에서 10분 동안 염색 처리한 경우가 가장 좋은 염색성을 나타내었고, 처리온도와 처리시간 모두 유사한 결과를 보였다. 염색 모발의 염착량(K/S값)은 처리 온도와 시간에 따라 모두 유사한 경향을 나타났으나 처리 온도가 증가될수록 염착량은 감소되었고, 20oC에서 가장 높은 염착량을 나타내었다. 증류수, 일반 샴푸제, 칼라 전용 샴푸제를 이용한 세정 견뢰도는 반복적으로 세정 횟수가 증가할수록 색의 물 빠짐이 크게 나타나 추출물의 유지력이 낮아진다는 것을 확인할 수 있었다. 그러나 칼라 전용 샴푸제로 세정 했을 때는 염료의 물 빠짐이 지연되는 것으로 나타났다. 일광 견뢰도는 햇빛에 대한 노출 빈도가 증가할수록 염색의 색바램이 증가되는 것으로 나타났다. 이상의 결과로 볼 때 소목 열수 추출물의 염료는 모발 염색성은 있으나 견뢰도에 따른 염료의 지속성 유지에는 문제가 있어 모발 염료로 활용하기 위해서는 보다 다양한 연구가 필요하며, 견뢰도를 해결할 경우 새로운 천염 염료의 소재로 이용은 있을 것으로 사료된다. This study was to examine the effect of color and colorfastness depended on temperature and dyeing time by using hot water extract form Caesalpinia sappan L. The dyeing temperature was 20oC, 30oC, 50oC, and 70oC and dyeing time was respectively 10, 20, 30, and 50 minutes. The colorfastness was measured by the washing with distilled water, plain shampoo, color shampoo and daylight. As the result, dyed hair color was red and dependant of dyeing time and temperature. The effect of dyed hair which appeared at 30oC for 10 minutes was higher than others. The value of lightness(L*), redness(a*), yellowness(b*) and color difference(E) was measured 47.22, 43.53, 43.78 and 48.06 respectively. The rate of washing colorfastness was decreased with repeated washing distilled water, plain and color shampoo. The daylight colorfastness was largely decreasing as washing. From these results, we can confirm that the hot water extracts from Caesalpinia sappan L. may be useful in the materials of hair coloring dye.
