High Fastness Dyeing Technology of Polyester Microfiber with Several Disperse Dyes and Vat dye
Textile Coloration and Finishing, volume 15, issue 6, 2003, Pages 1~7
Polyester microfiber has usually greater dye uptake than normal denier polyester fiber in same dyeing condition. In spite of this high dye uptake dyed microfiber fabric has not only low visual colour depth but also poor washing fastness property. In order to study high colouring dyeing technology and high washing fastness of polyester microfiber, dyeing property of polyester microfiber was investigated according to the dye solubility and particle size of used disperse dyes in aqueous dye solution. After disperse dyeing, dyed fabric with disperse dye was redyed with a vat dye without reduction clearing in order to obtain a high washing fastness property. The result were as followings ; A small particle sized disperse dyes such as C. I. Disperse Blue 56 and Red 60 showed high rate of initial exhaution compared with a large particle sized disperse dyes like C. I. Disperse Blue 165 and Red 343. In study of dyeing property of polyester microfiber with C. I. Vat Blue 1, polyester microfiber could achieve high dye uptake at a given optimum vatting process conditions. On the other hand, in consecutive dyeing with disperse and vat dye, K/S value of polyester microfiber with a small particle sized disperse dye increased without reduction clearings, but K/S value of polyester microfiber with a large particle sized disperse dye decreased with reduction clearings.
A Study on the PVA Particle Manufacturing for Polymerization Type Fine Toner
Textile Coloration and Finishing, volume 15, issue 6, 2003, Pages 8~17
In order to investigate the possibility of PVA particle as toner, PVA/PVAc particle was manufactured. Fine spherical PVAc particle with emulsifier SDS(sodium Dodecyl Sulfate) and initiator V-50(2,2'- azo bis(2-amidinopropane) dihydrochloride) was manufactured by emulsion polymerization. And then, the PVAc was carried with surface saponification. PVA/PVAc skin core structured particle was obtained under optimum saponification condition. PVA skin side in manufactured PVA/PVAc particles was dyed with 1:2 metal complex type C. I. Acid Yellow 235 and then the dyed PVA particles were observed with a optical microscope. Under given polymerization condition such as SDS concentration,
, V-50 concetration,
, the high molecular weight of PVAc with Pn 13,900 and PVA with Pn 3,400 was produced. The particle distribution of obtained PVAc microspheres was appeared highly at 60 and
Application of an Anionic Syntan on Nylon 6.6 Fibers: Exhaustion Properties and Staining Resistance
Textile Coloration and Finishing, volume 15, issue 6, 2003, Pages 18~26
Nylon 6.6 was treated with anionic synthetic tanning agent at different pH values, temperatures and liquor ratios to determine exhaustion properties. Treatments using syntan were conducted to the undyed nylon 6.6 fiber and three acid dyeings and then samples of the bath solution were subjected to HPLC analysis. Mass analysis was considered to determine the syntan components. In addition, the effect of applications using syntan and syntan/cation in improving the stain resistance was observed. The optimum treatment condition of syntan was achieved and the major component of syntan, being exhausted to the nylon substrates, was determined. In terms of stain blocking effect, a significant improvement was achieved by the syntan and syntan/cation treatments.
Antimicrobial Finishing of Cotton Fabrics Using Gallnut Extracts
Textile Coloration and Finishing, volume 15, issue 6, 2003, Pages 27~32
As a natural antimicrobial agent, gallnut extract was examined. The extract was separated and analyzed by LC/MS to assign the components, gallic acid, digallic acid, trigallic acid, mono-galloyl glucose, penta-galloyl glucose, etc. Minimum inhibitory concentration of gallnut extract was about 10ppm. Cotton fabrics treated with 10% owf of gallnut extracts had antimicrobial activity showing the reduction of bacteria 99.9% for both Staphylococcus aureus and Klebsiella pneumoniae.
Effect of False Twist Processing Conditions on the Physical Properties of PET DTY
Textile Coloration and Finishing, volume 15, issue 6, 2003, Pages 33~38
This study surveys the effects of POY physical properties and processing conditions of belt texturing machine to the textured yarns. The various textured yarns are made with the variations of 1st heater temperature, draw ratio, velocity ratio, and the physical properties of these specimens such as yam linear density, tenacity, breaking strain, and wet and dry thermal shrinkages are measured and analysed with the various processing conditions of texturing machine. Especially, the thermal characteristics of the textured yarns, which are affected at the fabric hands and the determination of the processing conditions in the dyeing and finishing processes, are investigated through the thermal stress analyser and DSC experiments.
A Study on the Dyeing according to Kinds of Loess
Textile Coloration and Finishing, volume 15, issue 6, 2003, Pages 39~46
The experiments about dyeing concentration, temperature and time were done using yellow, red and purple loess as natural inorganic dyes in order to verify a degree of dyeing, characteristics of color and fastness. The results were as following; 1. As a result of analyzing components of loess, purple loess was much than other loess in quartz component and coarse particles contained. This affected to the degree of dyeing. 2. The stronger dyeing concentration was, the more the degree of dyeing was improved, and yellow loess containing fine particles was the best in the degree of dyeing. 3. When it was dyed with raising up to
for 10 minutes after stirring for 20 minutes at
, was better than on starting at
in the degree of dyeing. Also yellow loess was the best in these experiments. 4. Washing fastness of loess was low such as other natural dyes, but dyeing wasn't transferred to other textiles. On the other hand, light fastness of it was very excellent and rubbing fastness was relatively good as 3~3.5.
Dyeability Improvement of Berberine Colorant by Electrostatic Attractive Force of a Reactive Anionic Agent
Textile Coloration and Finishing, volume 15, issue 6, 2003, Pages 47~54
To be dyed with cationic Berberine, the cotton fiber was modified with reactive anionic agent. The Berberine, a natural cationic colorant of pure yellow, is the major component of Amur Cork tree extract and also can be employed as a natural antimicrobial agent due to its characteristic of cationic quaternary ammonium salt. By LC/MS analysis, it became obvious that the Berberine was contained in Amur Cork tree extract as a major color component. The adsorption of the Berberine on the cotton fabrics pretreated with the anionic agent was greatly increased comparing to that of untreated fabric. Because the anionic agent was colorless, it did not cause unintended color change of the dyeings. The dyed fabric with the Berberine has strong antimicrobial activity showing 99.5% of reduction of bacteria against Staphylococcu aureus.
Dyeing of Wool at Low Temperature - focusing on solubility parameter
Textile Coloration and Finishing, volume 15, issue 6, 2003, Pages 55~62
Wool fabrics were dyed with the aqueous solution of C. I. Red Acid 114 mixed with methanol dissolving three kinds of barely water soluble ketones, acetophenone, 2-pentanone, and 3-pentanone. The steric hinderance and the orientation of the bigger hydrophobic part of the solvated dye molecules to the fiber slowed down the dying rate, however, loosening the wool molecule, say a little swelling, disaggeregating the dye molecules, and attaining the higher dye concentration on the fiber surface by the added solvents increased the amount of dye on the fabric. The higher concentration or/and the higher dyeing temperature helped loosen fiber molecules and made it easier for the solvated dye molecules to penetrate into the inside of the fiber. Acetophenone, the most influential solvent used, showed that the ability to loosen fiber molecules was the most important of all the three positive solvent actions mentioned above. The considered mechanism provided before reflected the fact that the dye uptake on the fabric dyed with the solvents included, except for 0.034M and 0.051M of acetophenone, was even lower than that without any solvents at
, but all the solvents added to the dye bath increased the dye uptake on the fiber at
