성우경 ( Woo Kyung Sung ) 한국의류산업학회 2011 한국의류산업학회지 Vol.13 No.5

This study was carried out to investigate dyeing characteristics of CDP(cation dyeable polyester)/silk knitted fabrics with disperse type cation dyes/acid dyes by one bath dyeing method in comparison with two bath dyeing method in the interests for rationalization of the dyeing process. The apparent color depth(K/S) of the disperse type cation dyes with CDP and that of acid dyes with silk decreased slowly with increasing pH values of dyebath with the exception of sharp decrease at alkali region for CDP. The contamination behavior of CDP by the acid dyes and that of silk by the disperse type cation dyes decreased with progressing of dyeing. The migration ratio(%) of the disperse type cation dyes with CDP is low compared with that of acid dyes with silk. The sediment in mixed dying solution of disperse type cation dyes and acid dyes remarkably less compared with that of regular type cation dyes and acid dyes at 100˚C regardless applying of preventer agent of precipitation. When CDP/silk knitted fabrics was dyed with by with mixtures of disperse type cation dyes/acid dyes one bath or two bath dyeing method, the characteristic of reflectance spectra of CDP components were greatly influenced by disperse type cation dyes and that of silk components by acid dyes. It was confirmed that K/S values of each components of CDP/silk knitted fabrics dyed by one bath dyeing method decreased slightly compared with two bath dyeing method.

정의정,허정록 국제보건미용학회 2022 국제보건미용학회지 Vol.16 No.2

With the diversification and popularity of hair dyes, the alkali ingredient in hair dyes has caused hair damage, having a negative impact on hair color retention. According to studies on organic acid perms, organic acid inhibited alkali activity and reduced hair damage, enhancing wave formation and durability. Based on such results, this study attempted to investigate the influence of organic acids such as succinic acid and tartaric acid on color retention after dyeing by applying them as post treatment. The alkali substance in hair dyes accelerates their absorption into hair, but its residue can also cause hair damage. Since the dyes absorbed into hair cortex are easily leaked out, organic acids were used as post treatment, and the results found the followings: First, after coloring the bleached hair cherry red and blue silver, it was post-treated with succinic acid and tartaric acid. When changes in hair color were measured through repetitive shampooing, the experimental group (succinic acid/tartaric acid group) was better than a control group in terms of hair dye retention. Second, in terms of hair damage after hair dyeing, the experimental group was lower than a control group with high tensile strength, narrow pores and smooth hair texture. In other words, the post treatments ‘succinic acid’ and ‘tartaric acid’ prevented protein extraction by inhibiting hair swelling after neutralizing alkali on the hair. In other words, organic acids reduce hair damage and have a positive effect on hair color retention. The above results confirm that the development of post-dye treatments using organic acids reveal a positive influence on hair.

Two novel perylene-based acid dyes were synthesized to produce fluorescent polyamide fabrics. The dyes were made by reactingperylene-3,4,9,10-tetracarboxylic acid dianhydride (PTCA) with sulfanilic acid and 1-amino-8-hydroxy-3,6-naphthalenedisulfonic acid (H-acid) in imidazole as a solvent. FTIR, 1HNMR, UV–Vis, elemental analysis, and spectro-luminescencewere used to characterize the synthesized dyes. Dyes with approximately similar maximum wavelengths had molar absorptioncoefficients of 42,996 and 8636 l mol-1 cm-11 in water. The dyes showed a negative solvatochromism effect with changing thepolarity of solvents from water to methanol. Also, the sulfanilic acid-based dye had a higher quantum efficiency (φ = 0.79)and stokes shift (1999 cm-1) than the H-acid-based dye in water. The DFT method analyzed the synthesized dyes' HOMO,LUMO, bandgap, dihedral angles, and angle of substitution. Both dyes had the same bandgap and dihedral angles. Substitutedsulfanilic acid derivative had more planar structure than H-acid derivative. The synthesized molecules were used to dyepolyamide fabrics. Dyeing kinetics were based on pseudo-second-order and Langmuir isotherms. Also, the sulfanilic-acidderivative had more build-up on polyamide fabrics. According to fabric fastness tests, synthetic dyes had excellent washingand rubbing stability but weak to moderate light fastness. Finally, the fluorescent properties of dyed fabrics were obtained.

Azo Acid Dyes Based on 2H-Pyrido[1,2-a]Pyrimidine-2,4(3H)-Dione with Good Tinctorial Power and Wetfastness - Synthesis, Photophysical Properties, and Dyeing Studies

Yogesh Gawale,Amol Jadhav,Nagaiyan Sekar 한국섬유공학회 2018 Fibers and polymers Vol.19 No.8

A series of five azo acid dyes were synthesized using different diazotized aromatic amine sulfonic and carboxylic acids followed by coupling with 2H-pyrido[1,2-a]pyrimidine-2,4(3H)-dione. The dyes were characterized by 1H-NMR, 13CNMR, FTIR, and elemental analysis. They were applied on nylon, silk, and wool. Their fastness properties were evaluated and color on the fabric was assessed. Yellow, brown, and crimson dyeings with good fastness properties were obtained. The dyes are water soluble and showed absorption from 380 nm to 550 nm. Acid dyes from diazo component 4- aminonaphthalene-1-sulfonic acid (naphthionic acid) and 4-amino-5-hydroxynaphthalene-2,7-disulfonic acid (H-Acid) were found to be more red shifted as compared to the other dyes. More red shifted absorption maximum was observed in acidic pH than in alkaline pH. The trends in vertical excitations obtained from Time Dependent Density Functional Theory calculations are in good agreement with the experimental absorptions.

Two acid dyes having excellent antimicrobial activity were synthesized by using silver sulfadiazine, a well-known antibiotic, and 8-amino-1-naphthol-3,6-disulfonic acid (H-acid). The diazonium salt of silver sulfadiazine (S1) and the acetylated H-acid (H1) were prepared first, and then an antimicrobial red acid dye (Acid-Red) was synthesized via a coupling reaction of S1 and H1. An antimicrobial blue acid dye (Acid-Blue) was also synthesized by the successive coupling reactions of H-acid with the diazonium salt of aniline-2,5-disulfonic acid (B1) and the diazonium salt of sliver sulfadiazine (S1). Two colorless antimicrobial additives for disperse dyeing, Disperse-ES and Disperse-AS, were also synthesized by reacting silver sulfadiazine with diethyl sulfate and acetic anhydride, respectively. The synthesized antimicrobial dyes and additives were characterized by Fourier transform infrared (FT-IR), UV-vis, and energy dispersive X-ray (EDX) analyses. Although the nylon fabric dyed with either Acid-Red or Acid-Blue showed poor light fastness, it had good washing and crocking fastness. The nylon fabrics dyed with Acid-Red and Acid-Blue and polyethylene terephthalate (PET) fabrics treated with Disperse-ES or Disperse-AS showed excellent antimicrobial activities after 10 repeated launderings.

Although permanent hair dyeing gives an advantage to wash fastness, it may introduce damages on hair skin from the oxidant used. On the contrary, when acid dyes are used for semi permanent hair dyeing, they show poor wash fastness in the absence of damages on the hair. In the present study, the milling acid dyes, such as C.I. Acid Red 114 was chosen to approach the appropriate conditions for semi-permanent hair dyeing. The chemical structures of dyestuffs were characterized by UV and FT-IR analysis. The maximum absorption wavelength determined by the UV-visible spectrum were 620㎚ for the respective dyestuff of C.I. Acid Red 114. the dyeing solution containing solvents such as acetophenone(C6H5COCH3), benzyl alcohol(C6H5CH2OH), ethyl alcohol(C2H5OH), propyl alcohol(CH3CH2CH2OH) and tributylphosphate. In this work, we investigated the effects of benzyl alcohol in hair dyeing with C.I. Acid Red 114 acid dye. When benzyl alcohol was added in the bath, the uptake of C.I. Acid Red 114 was increased dramatically. Dyeability of hair increased significantly by adding benzyl alcohol in C.I. Acid Red 114 . Neverthless the hair was slightly damaged during dyeing, the dyed hair showed a good wash fastness.

정의정,이상현 중소기업융합학회 2021 융합정보논문지 Vol.11 No.12

In this work, the post-treatment using organic acids during hair dyeing process was used to maintain hair color and to decrease hair damage. The effect of post-treatment using succinic acid and tartaric acid during hair dyeing process with cherry red and blue silver color on the persistence of hair color, tensile strength of hair, hair porosity, and surface characteristics of hair was investigated. After the repeated shampooing process, the experimental group with succinic acid and tartaric acid could more efficiently maintain the hair color than control group. The experimental group with succinic acid and tartaric acid could also increase the tensile strength of hair, decrease the hair porosity, and smoothen the hair surface, compared with control group. Particularly, tartaric acid was able to maintain the color of the dyed hair and protect the hair with higher efficiency than succinic acid. 본 연구는 염색 과정에 유기산을 이용한 후처리를 적용하여 염색의 지속성을 높이고 모발의 손상을 억제하고자 하였다. 체리레드와 블루실버 색상으로 탈색모를 염색하는 과정에 succinic acid와 tartaric acid를 이용하여 후처리 하고 염색된 모발의 색 지속성, 인장강도, 기공, 표면 특성을 알아보았다. 반복적인 샴푸 세척을 진행한 후 모발의 색상변화를 측정한 결과 succinic acid와 tartaric acid 실험군은 대조군 보다 효율적으로 모발의 색상을 유지할 수 있었다. 염색 후 모발의 손상도를 측정한 결과, succinic acid와 tartaric acid 실험군은 대조군 보다 높은 인장강도, 낮은 기공도, 매끄러운 표면 특성을 나타내어 모발 보호 효과를 나타냈다. 특히, tartaric acid는 succinic acid 보다 높은 효율로 염색모의 색을 지속시키고, 모발을 보호할 수 있었다.

Although permanent hair dyeing gives an advantage to wash fastness, it may introduce damages on hair skin from the oxidant used. On the contrary, when acid dyes are used for semi permanent hair dyeing, they show poor wash fastness in the absence of damages on the hair. In the present study, the milling acid dyes, such as C.I. Acid Blue 90 were chosen to approach the appropriate conditions for semi permanent hair dyeing. The chemical structures of dyestuffs were characterized by UV and FT-IR analysis. The maximum absorption wavelength determined by the UV-visible spectrum were 520㎚ for the respective dyestuff of C.I. Acid Blue 90. The milling type acid dyes showed good affinity to hair. As the concentration of acid dyes increased from 0.1% up to 1.0%, the dye adsorption to hair was sharply increased at relatively lower concentration and reached saturation at above 0.3 - 0.4% showing almost Langmuir type isotherm. Therefore, the dyeing process can be explained as ionic bonding of the dye molecules on the positive site in the hair. The dyeing mechanism can be confirmed by the effects of pH on dye exhaustion shown as dye uptake increase at lower pH and higher K/S value obtained at higher temperature and longer dyeing time.

계면활성제가 모발 염모제의 산성 염료에 미치는 영향

김란(Ran Kim),장미화(Mi Haw Chang) 한국디자인문화학회 2015 한국디자인문화학회지 Vol.21 No.2

국내시장에서 국산제품보다 외국 브랜드 염모제의 판매량이 더 높아 현실적으로 화학적 염모제를 사용할 수밖에 없는 상황이다. 이 상황에서 모발 염모제 제형화시 화학 성분 함유량을 낮게 낮추고, 여러 가지 화학 첨가물을 최소화하는 것이 필요하다. 또한 유해 성분 사용을 금지하고, 염색성을 향상시키는 방법을 연구해서 모발 염모제의 안정성을 높이는 것이 바람직하다고 생각한다. 본 연구는 밀링형 산성 염료 중에서 Disazo계 산성염료인 C.I. Acid Red 114을 선정한 후 모발 염모제인 산성 염모제를 제형화 하려고 한다. 산성 염모제를 제형화 시킬 때 다양한 첨가물이 들어가는데 그 중에서 계면활성제에 대한 효과를 검토하고자 한다. 가장 우선적으로 산성 염료로 모발 염모제 제형화시 사용된 염료의 최대흡수파장 λmax과 구조를 확인하기 위해서 FT-IR분석, UV-Vis 흡수스펙트럼 분석을 해보았다. FT-IR분석에 의해 염료의 구조를 확인 하였으며 용매로는 benzyl alcohol (C6H5CH2OH)를 사용하였다. 계면활성제의 종류에는 양이온 계면활성제, 음이온 계면활성제, 비이온 계면활성제를 첨가하여 모발의 염색성을 검토하였다. 실험 결과 산성 염료에서는 양이온 계면활성제가 염색성이 우수하였다. 또한 양이온 계면활성제를 농도 별로 염색을 실시하여 농도가 0.15%∼0.2% 첨가하였을 때 가장 염색성이 우수함을 알았다. 산성 염료는 염료분자가 커서 모발 깊숙이 침투하지 못하고 모발 표면에 흡착하여 세정 견뢰도가 낮아서 여러 가지 계면활성제를 가지고 세정 견뢰도를 실험한 결과 양이온 계면활성제가 다른 계면활성제 보다 우수하였다. 그 이유는 양이온 계면활성제가 염료와 반응하여 모발의 표면에 염착되어 모발과의 염착력을 증가시키고 모발과 염료간의 이온 결합력을 증가시키기 때문이라고 추측할 수 있다. Because foreign brands hair dyes outsell domestic products in the domestic market. so we cannot help using chemical hair dyes. Therefore, when hair dyes is formulated, it is required that content of chemical composition lower its content and minimize many chemical additives. Also, harmful ingredients are prevented and it is desirable that stability of hair dyes become high through improving dyeing property. In the present study, the milling acid dyes, such as C.I. Acid Red 114 was chosen to approach the appropriate conditions for Acid Dyes. When surfactants was added in the bath, the uptake of C.I. Acid Red 114 was increased dramatically. the surfactant was used as a cationic surfactant, an anionic surfactant, a noninoic surfactant. The chemical structures of dyestuffs were characterized by UV and FT-IR analysis. The maximum absorption wavelength determined by the UV-visible spectrum were 620㎚ for the respective dyestuff of C.I. Acid Red 114. Dyeing is a cationic surfactant was the most effective. As the concentration of cationic surfactant increased from 0.15% up to 0.2% the dye adsorption. Acid dyes low in washing fastness of the dye molecule cursor, as a result of the washing fastness test with a surfactant, the cationic surfactant is a high fastness. The behaviour is explained by the cationic surfactant access to the hair surface in advance of the dye molecules which then improve affinity of the dye molecules in hair surface.

Union dyeing of cotton/nylon blended fabric by plasma-nano chitosan treatment

Karthikeyan Kaliyamoorthi,Ramachandran Thangavelu 한국의류학회 2015 Fashion and Textiles Vol.2 No.1

Current union dyeing processes rely on one or two dye baths with one or two dyes for cotton/nylon blend fabrics. For 50:50 cotton/nylon fabrics, cotton is dyed first under alkaline condition with reactive dyes and then the nylon is dyed with acid dyes under acidic condition. Atmospheric plasma- nano Chitosan treatment as an environmentally friendly method was employed to modify surface properties of cotton/nylon blend fabrics to develop union dyeing with acid dyes. Cellulose fibers when immersed in water produce a negative electro-kinetic potential. The negative charge on the fiber repels the anionic dye ions and consequently the exhaustion of the dye bath is limited. When the fabric is treated with chitosan, the primary hydroxyl groups of cellulose is partially modified into amide groups, which intern leads the cellulose to act like as polyamide fiber. Experimental work was carried out on finding the possibility of one bath dyeing of plasma- chitosan pretreated cotton/nylon fabric with acid dyes. Plasma treated cotton/nylon surface characteristics were evaluated using FTIR. The surface activation using air plasma introduces different functional groups in cotton/nylon blend fabric. The effect of plasma-nano chitosan pretreatment on dye ability, fastness, and few physicochemical properties has been investigated, and results are presented. The cotton/nylon sample treated with 0.3% of chitosan nanoparticles had higher K/S values, washing, and crocking fastness. New method of union dyeing showed good fastness properties and offers the option of eco-friendly.
