The Dyeability properties of some yellow Natural Dyes (I) -Extracted from Gardenia-
Textile Coloration and Finishing, volume 10, issue 1, 1998, Pages 1~10
The objectives of this study were to investigate the effects of mordants and dyeing method : on the dyeability and color fastness of the fabrics with the extract from Gardenia. The following results were drawn from the data obtained. 1. The wavelengths of the strongest absolution bands of Amur cork tree, Gardenia extract was 440nm respectively and the wavelengths 440-460nm after the mordants were added in the color extracts(The bands of Gardenia extract shifts to short wavelength side as pH increased.). In all cases, the abosorbancies were increased. 2. The main color substances in extract from Gardenia were expected to be cretin respectively by spectrophotometric and HPLC studies. 3. As to the concentration of color extract for dyeing, about 20g/L was the optimum concentration to dye silk and cotton fabrics with extract. 4. For silk and cotton fabrics dyeing with Gardenia extract,
was the best mordants. The K/S values of dyed fabrics were increased gradually as the concentration of mordants increased, and the highest K/S values were obtained at 5-10%. When using the mordanting methods, silk fabric by premordanting and cotton fabric by synmordanting had a greater effect K/S value. 5. The color fastness of fabrics dyed with Gardenia extract against dry cleaning, washing, rubbing and perpiration was improved 1 level or so but light fastness was remained 1 level showing without any effect.
The Study of Cochineal Dyeing.
Textile Coloration and Finishing, volume 10, issue 1, 1998, Pages 11~19
For the purpose of standardization and practicability of dyeing by natural dyes, the mordanting and dyeing properties of cochineal and carminic acid were studied. Appropriate extraction, dyeing and mordanting condition of cochineal were determined, and the effect of mordanting method on dye uptake and color fastness of dyed fabric was investigated. The maximum absorbance of cochineal solution was 495nm, carminic acid was 533nm and 577nm. The color of carminic acid solution was affected by pH 6~9. The optimum temperature to extract cochineal was
and dyeing solution for 1 hour. And effective dyeing time to silk was 60min. Effective mordanting temperature was
, and its time was 30min. In case mordants concentration, the maximum absorbance of Sn solution was 3%, K, Cu and Cr were in 1%. K/S value of dyeing fabrics was recoginazed by mordant treatment, specially Fe, Sn, Al, Cu. In the case of cochineal light fastness was increased by mordant treatment, specially Fe treatment. Perspiration fastness was good in acidic solution than in alkaline solution and perspiration fastness of cochineal was poor. Fastness of abrasion and dry-cleaning were good and these fastness improvement were generally effective for post-mordanting treatment.

Oligomeric extracts of poly(ethylene terephthalate-co-ethylene isophthalate)s [(PET/EI] are analyzed by high performance liquid chromatography(HPLC) and nuclear magnetic resonance spectroscopy (NMR). Existence of separated peaks for small cyclics of trimer and tetramer gives the existence of structural isomeric forms. NMR confirms that cyclization of PET/EI occurs more easily at the site of isophthaloyl unit.
Organic Solvent Dyeing(II) -The Dyeing of PET by C. I. Disperse Violet 1 in Alkanes as Dyeing Media-
Textile Coloration and Finishing, volume 10, issue 1, 1998, Pages 25~32
In the prior study, we found that the dye uptakes of C. I. Disperse Violet 1 on PET in hexane and cyclohexane were higher than those in the other solvents. Therefore, in this study, the dye uptakes and the partition coefficients in alkanes having different number of carbon atoms were obtained and their relationship to the solubilities of the dye in alkanes was also investigated. As the number of carbon atoms of alkanes increases, solubility of the dye increases but the dye uptake decreases. This is due to the fact that the hydrophobicity of alkanes become relatively strong as increasing the number of carbon atoms. It was also found that the dye uptakes in iso-alkanes were larger than those in normal alkanes. This is because that the branched alkanes(iso-alkanes), judging from the tendency of lowering solubility and increasing dye uptake as decreasing the number of carbon atoms of alkanes, behave like the alkanes with less number of carbon atoms rather than the alkanes with the same number of carbon atoms. The logarithmic plot of the dye uptakes vs. the solubilities of the dye showed that the dye uptakes are linearly and inversely proportional to the solubilities. This is in good accordance with the results of the prior study. The heat of dyeing was also calculated from the equilibrium adsorptions at various temperatures. It seemed that the dyeings of PET by C. I. Disperse Violet 1 in nonane, decane, iso-pentane and iso-octane were rather endothermic processes. Dyeing rates in alkanes were somewhat delayed unlike general appearances in solvent dyeing.
Durable Water and Oil Repellent Finish of Wool Fabric(I)
Textile Coloration and Finishing, volume 10, issue 1, 1998, Pages 33~37
It is rather important in the water and oil repellent finishing for wool fabric what kind of water-repellent agents will be used. In many cases, Fluorocarbon-based water-repellent agents(eg.Oleophobol-S), the surface tensions of which very low, were recom-mended on account of good water and oil repellencies. In repellent finishing, fabrics were padded in a bath which contained aqueous solution of water-repellent agents, and wetting agents, followed by drying and curing. The most suitable treating condition for excellent repellency was as follows Fabrics were padded at liquor pick-up ratio of 50%, with aqueous solution which contained
of water-repellent agents, and
of wetting agents. And the padded fabrics were dried at
for 1 minute, and cured at
for 2 minutes. For the fabrics, water and oil repellencies and durability to repeated dry-cleanings are observed.
Development of Antimicrobial and Deodorizing Cellulose Fiber
Textile Coloration and Finishing, volume 10, issue 1, 1998, Pages 38~42
Both cellulose and chitin together were dissolved in DMAc/LiCl and these solutions were extruded into coagulant of
. Fibers thus obtained were treated in NaOH aqueous solution. Results showed that the fiber surface contains celluose and chitosan. This means that these fibers treated are composed of three components, ie, cellulose, chitin, and chitosan. These fiber showed secure antibacterial and mechanical properties.
The Effects of Impurities of Polyester Fiber Fabric on the Dyeing Property
Textile Coloration and Finishing, volume 10, issue 1, 1998, Pages 43~50
In order to investigate the effect of contained impurities of polyester fiber fabric on the scouring and dyeing property, 3 kinds of polyester fabrics were heat-set treated at
and evaluated its scouring and dyeing property by through with soxhlet extraction and K/S value of the dyed fabric derived from the surface reflectance. The impurities such as oiling and sizing agent are adhered more strongly on the polyester fabric surface by heat setting temperature. In scouring test, the removal of the these re-adhered impurities on the polyester fabric is very difficult in comparing with unheat-set treated polyester fabric. It is also confirmed that the remained impurities on the polyester fiber decreased its dyeing property.
