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.

This study was conducted to make help an environment-friendly dyeing method for natural indigo. In this study, glucose was used as a reducing agent for indigo. Four kind of fabrics composed of cotton fiber and flax fiber were used for this study. Dyeing with natural indigo was done under four different dyeing conditions having different pH levels and dyeing temperatures. Dyeing characteristics (color characteristics and color strength) and colorfastness were also measured. The dyeing differences in characteristics and colorfastness were analyzed based on the fiber type and dyeing condition. There were significant differences in color characteristics and color strength (K/S value) of fabrics dyed with natural indigo using glucose reduction based on the fiber type and dyeing condition. The K/S value of the fabric dyed with natural indigo through glucose reduction was the highest at 660nm. The colorfastness of the four fabrics dyed using natural indigo had a rate of 4 to 5 with the exception of rubbing fastness, which indicated good colorfastness.

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.

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.
