Kim, S. J. ; G. D. Yeo ;
Textile Coloration and Finishing, volume 12, issue 1, 2000, Pages 1~11
This paper surveys the fabric weavability and machine efficiency in the various weaving looms such as Projectile, Rapiers, and Air-jet. Used projectile loom was Sulzer-PU, and FAST-R, THEMA-11E, and Picanol-GTX were used for Rapier looms, as the Air-Jet looms, Picanol PAT and OMNI types were used. Using these looms, 5 harness worsted satin fabrics were woven for surveying the fabric weavability and machine efficiency. Warp yam count of fabric is 1/40Nm, Sirofil, and filling is 1/30 Nm, worsted. End breaks of warp and filling directions for the various types of looms are measured and discussed with the mechanism of each loom. Warp and filling yam tensions are also measured and analysed with open width of shedding motion of each weaving machine. And various warp yam tensions with open width of shedding are measured and analysed according to the warp yam in various heald frame. These results fire also discussed with temples such as bar and ring. Warp yam tensions at the various positions on the fabric with various looms are measured and discussed with fabric mechanical properties such as tensile, bending, shear and surface.
Dyeability of Fabrics in Lichen Dyebath
Textile Coloration and Finishing, volume 12, issue 1, 2000, Pages 12~16
Silk and cotton fabrics were dyed with Parmelia tinctorium that is a kind of lichen. Dyeing solution was prepared by fermentation in aqueous ammonia solution. The effects of pH and temperature in dyebath on dyeability were investigated. The maximum K/S value of each dyed fabrics was showed in 480nm. Silk fabrics showed better dyeability than cotton. Silk fabrics dyed well in acidic or neutral dyebath at
and cotton fabrics in neutral dyebath at
. Both of silk and cotton fabrics showed poor dyeability in basic dyebath because of colouring anionic groups in lichen. The Munsell values of dyed silk fabrics were appeared in R(red) range, and them of cotton fabrics in YR(yellow-red) range. Light fastnesses of dyed fabrics were as poor as 2 or 2-3 grades. Also, Laundering fastnesses of dyed silk fabrics were as poor as 2 grade and those of cotton fabrics were 3 or 3-4 grades. But dry-cleaning fastnesses of all dyed fabrics were good.
A Study on the Tensile Properties of Polyester Warp Knitted Fabrics
Textile Coloration and Finishing, volume 12, issue 1, 2000, Pages 17~24
The tensile properties of polyester warp knitted fabrics of satin and reverse satin structure with various lengths of underlap were studied. In the range of low tension, the satin warp knitted fabric showed larger tensile energy and elongation in the direction of
and larger tensile linearity, tensile resilience and initial modulus in
. Meanwhile, reverse satin one showed larger initial moduli in 0
and larger the others in
. In the range of high tension, the tendencies of both fabrics in
direction were almost the same as those in all direction. As the under laps were shorter for both fabrics, tensile linearity, tensile energy and elongation increased, but tensile resilience decreased in all directions. However initial moduli were changed little.
Isolation and Culture Characteristics of Strains for Color Removal of Disperse Dyes
Textile Coloration and Finishing, volume 12, issue 1, 2000, Pages 25~31
In order to decolorize disperse dyes by using biological treatment process, a strain which has potential ability to degrade disperse dyes was isolated from natural system. To increase the removal efficiency of decolorization in the aqueous solutions, the optimal condition of decolorization by this strain was investigated, and continuous plant test was also developed. The optimal culture conditions of temperature and pH were found to be 4
and 8.5~9, respectively. When yeast extract was mixed with polypeptone at the mixing ratio of 1:1 as a nitrogen source, decolorization efficiency was highest(93%) among the nitrogen sources. The strain to be screened was excellent to adjust to pH, and it seems to be have ability to control pH needed to growth. The optimal culture conditions in concentration of
were 0.1%(w/v) and 0.2%(w/v). The result of continuous plant process using wastewater was as following :
removal efficiency was over than 50%, and this strain was very excellent in decolorization-efficiency for the wastewater of Taegu dyeing complex.
Color Removal from Disperse Dye Solution Using White Rot Fungi
Textile Coloration and Finishing, volume 12, issue 1, 2000, Pages 32~43
Batch culture system and continuous culture systems were used to investigate the removal of disperse dye using white rot fungi. White rot fungi used in the study were Coriolus hirsutus IFO 4917, Lenzites betulina IFO 6266, Coriolus versicolor IFO 30340 and Phanerochaete chrysosporium IFO 31249. The results of the batch culture experiment showed that white rot fungi used in this study had excellent dye removal abilities. Phnerochete chrysosporium IFO 31249 was especially effective on the removal of disperse dyes. And continuous treatment of disperse red 60 was studied under two type of reactor using Phanerochaete chrysosporium IFO 31249. The removal efficiency of disperse red 60 for immobilized Phanerochaete chrysosporium IFO 31249 in continuous reactor with vertical matrix was increased 1.3 fold in
dilution rate when compared with continuous reactor without vertical matrix.
A Study on the One Bath Two Step Dyeing of Nylon/ Cationized Cotton Blends with Acid Dye/Direct Dye
Textile Coloration and Finishing, volume 12, issue 1, 2000, Pages 44~51
The conventional one bath exhaust dyeing system of nylon]/cotton blends with acid dye/direct dye involves a lot of neutral salt which affect dyeability of acid dyes. Because of conventional one bath exhaust dyeing system of nylonl/cotton blends with acid dye/direct dye needs acid dyes adjusted at a neutral liquor, suitable acid dye is limited. To improve dyeing property of nylon/cotton blends, cotton component was pretreated with cationizing agent containing chlorohydrine group in aqueous solution of sodium hydroxide. This study was carried out to investigate dyeing possibilities of nylon/cationized cotton blends with acid dye/direct dye in a non-neutral salt dyebath by one bath two step method. The concentration of direct dye was 1.0%, 0.7%, 0.3%o.w.f. respectively at a non, 1%, 3%owf of reserving agent for being almost equal color strength between nylon and 3% cationized cotton when nylon/3% cationized cotton blends was dyed with acid dye/direct dye at concentration of acid dye(1%o.w.f.) by one bath two step method.
Organic Solvent Dyeing(III) -The Interpretation of Dyeing Behavior by Thermodynamic Parameters on Dyeing of Polyester Fiber in Alkanes as Dyeing Media-
Textile Coloration and Finishing, volume 12, issue 1, 2000, Pages 52~60
In the prior studies, we reported that the dye uptakes of C. I. Disperse Violet 1 on polyester fiber in hexane and cyclohexane were higher than those in the other solvents, as the number of carbon atoms of alkanes decreased, the dye uptake increased, and the logarithmic plot of the dye uptakes vs. the solubilities of the dye showed that the dye uptakes are inversely proportional to the solubilities. In this study, for Interpretation of dyeing behavior of C. I. Disperse Violet 1 on polyester in alkanes, the thremodynamic parameters of dyeing, such as standard affnity, heat of dyeing(enthalpy change), entropy change, diffusion coefficient, and activation energy of diffusion, were obtained from isotherms and dyeing rates at different temperature. As the number of carbon atoms of alkanes increased, the standard affinity decreased, but the heat of dyeing(enthalpy change) and the entropy change showed larger negative values. These results mean that as the number of carbon atoms of alkanes increases, the dye uptake decreases, but both the fraction of the dye molecules dyed at relatively highly aligned or compact region of polyester fiber and the regularity of dye aggregates in the fiber become increased. As the number of carbon atoms of alkanes increased, the diffusion coefficient decreased, but the activation energy of diffusion increased. In the alkane of larger number of carbon atoms, because the solubility of the dye is higher, the desorption rate of the dye is faster and the diffusion coefficient is smaller than those in the smaller alkanes. But the energy required to separate the dye molecules from the alkane molecules is much higher because the interaction between the alkane molecule and the dye molecule become strong with the number of carbon atoms.
A Study on the Antimicrobial Finishing of Artificial Suede by Allylamine Copolymers
Textile Coloration and Finishing, volume 12, issue 1, 2000, Pages 61~67
This study was carried out to develope antimicrobial artificial suede by coating with water soluble polyurethane resin and the copolymer of N,N'-dialkyl-N,N'-dialkyl ammonium chloride (DADAAC) and acrylamide as a antimicrobial additve. The copolymer of DADAAC and acrylamide was synthesized by free radical initiation and intra-intermolecular propagation, and the prepared copolymers had sufficient compatibility with water soluble polyurethane resin. The MIC values of the prepared copolymers and antimicrobial characteristics of the artificial suede coated by polyurethane were evaluated. With the increase in the proportion of DADAAC, which is antimicrobially active part in the DADAAC/acrylamide copolymers, the MIC value becomes lower. The MIC value of DADAAC-AA (1 : 1) copolymer is below 30 ppm against S. aureus, and below 90 ppm against K pneumoniae. The artificial suede coated by water soluble polyurethane resin with 1.0% owl concentration of DADAAC/acrylamide copolymer has good antimicrobial fastness as to show colony reduction of above 90% and 80% against S. aureus and K. pneumoniae respectively in the shake flask test after 10 times of washing, and above 95% and 85% after 10 times of dry-cleaning. The elastic recovery of coated suede fabric is not affected up to 1.0% owf concentration of DADAAC-AA copolymer in the polyurethane coating.

Textile Coloration and Finishing, volume 12, issue 1, 2000, Pages 68~75
In this study, polyester DTY faille(yoryu) and N/NP microfiber fabrics were pretreated (desizing, scouring and shrinking) by Continuous Scouring and Shringking Equipment with rota-drum and conveyor type in which types were different with retaining method. The results were as follows. The shrinkage ratio of wp/wf direction of DTY fabrics scoured by conveyor type was 1.5/23% higher than those by rota-drum type at
with 10min. treatment. In this case, The shrinkage ratio of wp/wf direction by those types was about 15/27%, respectively. The shrinkage ratio of wp/wf direction of N/NP microfiber fabrics scoured by conveyor type was 1.5/23% higher than that by rota-drum type at
with 10min. treatment. The size add-on of DTY fabrics scoured at
with 10min. treatment by conveyor type and by rota-drum type were 0.15% and 0.42%, respectively. The size add-on of DTY fabric treated by rota-drum type decreased until 9min. of treated time, but increased after 9min. The size add-on of N/NP microfiber fabrics treated by conveyor type was decreased by increasing temperature and treated time, while the size add-on of that treated by rota-drum type was decreased until 6min. treated time and increased after 6min. The size add-on of N/NP microfiber fabrics treated by conveyor type at
for 10min. was 0.3% lower than that by rota-drum type.
