Effect of the Processing Condition to the Yarn Tension on the Belt-type Texturing m/c
Textile Coloration and Finishing, volume 16, issue 1, 2004, Pages 1~4
This research surveys the twisting and untwisting tensions according to the various processing conditions of belt type texturing such as draw ratio, 1st heater temperature and velocity ratio. The 1st heater temperature was changed from
, draw ratio was changed from 1.6 to 1.9 and velocity ratio was changed from 1.4 to 1.8. The twisting and untwisting tensions are measured with the variation of these processing conditions, in addition, the untwisting tension(T2) and tension ratio(T2/Tl) according to the various processing conditions are analysed with the false twist mechanism which is affected to the physical properties of draw textured yams.
A Study on the Threadline Instability on the Belt-type Texturing Process
Textile Coloration and Finishing, volume 16, issue 1, 2004, Pages 5~9
This research surveys the threadline instability on the belt texturing machine according to the 1st heater temperature, draw ratio and velocity ratio. the threadline instability to the time, which is called surging phenomena, is analysed with variations of draw ratio and velocity ratio. In addiction, the surging phenomena is investigated with the variation of the untwisting tension and false twist mechanism on the belt texturing machine. The breaking strain, modulus and yam unevenness of the DTY along the yarn length are measured and analysed with the surging phenomena which is due to untwisting tension variation on the threadline according to the draw ratio, 1st heater temperature and velocity ratio.
Modification of Dyeing Property of Wool Fabrics by UV Irradiation
Textile Coloration and Finishing, volume 16, issue 1, 2004, Pages 10~17
Wool fabrics were treated with deep UV for 10 to 30min and then dyed with C.I. Acid Yellow 99, C.I, Acid Red 57 and C.I. Acid Blue 62. FT-IR and XPS have been used to prove the chemical composition of wool fiber surfaces. The mechanical property and colorfastness were also studied. The intencities of the peaks of C=O group at
were increased with increasing irradiation time. Relative
intensities increased considerably and oxygen was incorporated in the form of CO and COO on the fiber surface. The dye uptakes of wool fabrics dyed with three acid dyes were proportional to irradiation times and in inversely proportional to irradiation distances. It was found that the tensile strength of wool fabrics were gradually deteriorated with the UV irradiation times. The colorfastness, such as washing, light and rubbing, of UV irradiated wool fabrics dyed with acid dyes were good.
Carrier Dyeing of Polyester Fabrics in Alkaline Dyebath Using Microwave
Textile Coloration and Finishing, volume 16, issue 1, 2004, Pages 18~25
In this study, the effect of microwave which can increase temperature rapidly on polyester alkaline dyeing was investigated. The final K/S values of polyester fabrics dyed by microwave lower than those of atmospheric dyeing because of the evaporation loss of dyeing solution. If the dyeing time makes longer as much as that in atmospheric dyeing, the K/S values of polyester fabrics dyed under microwave were similar to those of atmospheric dyeing. The K/S values of polyester fabrics dyed in pH 9.5 were higher than those in pH 5.5 in case of aliphatic carriers. The K/S values of organic reagent pretreated polyester fabrics dyed by use of aromatic carriers were not higher than those of non-treated polyester fabrics. But the K/S values of polyester fabrics dyed by use of aliphatic carriers were higher than those of non-treated polyester fabrics. The tensile strength were decreased with increasing of dyebath pH because the polyester fabrics were easily decomposed by high alkali.
Dyeing of N/P Union Fabric with Reactive Disperse Dyes
Textile Coloration and Finishing, volume 16, issue 1, 2004, Pages 26~33
Two reactive disperse dyes having
-bromoacrylamide or acrylamide group were synthesized and their dyeing properties were compared with a disperse dye. Dyeing properties of reactive disperse dyes were strongly influenced by the chemical structure of reactive group. The amount of absorbed reactive disperse dye containing
-bromoacrylamide group on polyester fiber was less than the disperse dye, and that on nylon fiber was much higher. When polyester and nylon fiber were simultaneously dyed in a dye pot, nylon fiber absorbed the reactive disperse dye more than polyester fiber. The reactive disperse dye having acrylamide group could reduces difference in color depth to a large extent, but the application of carrier or variation of dyebath pH were not sufficient for giving the same color depth to both fibers. The N/P union fabric could be dyed with the reactive disperse dye and its wash fastness were good to excellent.
The Dyeing Properties of Silk Fabrics of Glycyrrhizae Radix Extract
Textile Coloration and Finishing, volume 16, issue 1, 2004, Pages 34~39
Dyeing properties of Glycyrrhizae Radix was investigated with silk fabrics. Dyeing water is a type of chalcone, it showed yellow in IR spectrum. K/S value showed high in following conditions; Glycyrrhizae Radix
of dyeing temperature, 90 minute of dyeing time. Glycyrrhizae Radix dyeing water has higher K/S value in alkalinity(pH9) than in neutrality(pH7) or acidity(pH3) conditions. K/S value showed highest in pH5 premordant method of alkalinity dyeing water condition. The color of silk fabric dyed with Glycyrrhizae Radix is yellow. The change of color did not show by mordant treatment. K/S value showed higher in mordant treatment than nonmordant. Light fastness showed over 3 degree in nonmordant, premordant, simmordant(Al,Cu,Fe) and postmordant(Cu). Water fastness showed over 3 degree in dyeing water(pH3, pH5, pH7). Dry cleaning fastness showed over 3 degree in all dyeing methods. Washing fastness is showed in 2-3 degree; Al in nonmordant, premordant, simmordant and Cu in simmordant are 2-3 degree. Perspiration fastness is nearly 3-4 degree in premordant and simmordant. Perspiration fastness shows high in premordant, simmordant than postmordant. The fastness of light, water, dry cleaning, washing, perspiration shows better nonmordant, premordant, simmordant than postmordant method.
A Study on the Weight Loss of Island-in-a Sea Fabrics by Ultrasonic
Textile Coloration and Finishing, volume 16, issue 1, 2004, Pages 40~47
Alkaline treatment gives Sea-Island type yam to produce microfiber and silk-like touch. But this treatment have some problems in dyeing and finishing process. To solve some problem occurred in dyeing and finishing of polyester fabric, the ultrasonic treatment technique was used recently. This study was carried out to confirm the effect of the ultrasonic treatment on alkaline weight loss finishing of polyester fiber under general alkaline treatment conditions; NaOH concentration 2, 3, 4, and 5％, treatment time 5, 10, 15, and 20 minutes, treatment temperature 70, 80, 90, and 99'E, respectively. On the other hand, the three way lay out method was used to test of significant obtained data from alkaline treatment. It was found that weight loss increased with increasing the NaOH concentration, temperature, and time. Also, in case of PET/Co-PET fabrics by ultrasonic, weight loss and dissolution of microfiber were superior to PET/Co-PET fabrics without ultrasonic. Tensile strength and modulus decreased with increasing NaOH concentrations and hydrolysis time. Therefore, the effect of alkali hydrolysis by ultrasonic application was better than that of the conventional method.
The Effect of the Molecular Weight of Poly(ethylene glycol) on Diffusion through Cellulose
Textile Coloration and Finishing, volume 16, issue 1, 2004, Pages 48~52
Diffusion/penetration rates of finishing agents are not a major criterion in the design of low molecular weight finishing agents. However, in the case of polymeric finishing agents, high molecular weights result in large hydrodynamic volumes and diffusion/penetration of the finishing agent into the substrate may become a critical factor in the design of textile finishing agents. Thus the effect of the molecular weight of a model compound, polyethylene glycol, on its diffusion through a cellulose membrane or cotton fabric is studied. Diffusion experiments of polyethylene glycol of molecular weight 400, 1000, 2000, 4600, 8000, and 10000 through cellulose membrane or fabric was carried out in a glass U-tube diffusion apparatus and the half penetration times and the penetration coefficients were determined. Both the half penetration times and the penetration coefficients exhibited a significant change between molecular weight 2000 and 2500 as the molecular weight of polyethylene glycol increased, suggesting that there is a critical molecular weight above which diffusion/penetration becomes difficult. Based on this study on a model compound, it is suggested that polymeric textile finishing agents can be expected to exhibit similar behavior.
Responsive fibers from Modification of Acrylic Fibers
Textile Coloration and Finishing, volume 16, issue 1, 2004, Pages 53~58
The preparation of responsive fibers from acrylic fibers is studied. Various responsive fibers, such as fibers which change their color on exposure to light or with change in temperature, have been developed and are used commercially However, the responsive material in these fibers are not the fiber itself but chemicals in microcapsules attached to the fibers by finishing, and few fibers exhibit responsive properties by itself. The partial hydrolysis of polyacrylonitrile fibers to obtain pH responsive fibers is presented in this paper. Partial hydrolysis was effected by control of the concentration of the sodium hydroxide used in the hydrolysis, hydrolysis temperature and time. The degree of hydrolysis was evaluated by nitrogen content of the hydrolyzed fibers and their response, change in length, to aqueous solutions of varying pH was studied by continually changing the pH. Significant changes in lengths with pH were observed and the gel transition behavior varied with the conditions of hydrolysis. The hysteresis of the length change was also studied to evaluate the possibilities of using hydrolyzed acrylic fibers as pH sensors.
A Studies on the Surface Morphology and Fine Structure of PET Film Treated by DMF
Textile Coloration and Finishing, volume 16, issue 1, 2004, Pages 59~64
As a simulation of solvent-assisted dyeing, the solvent effects on the structure of polyethylene terephthalate(PET) film treated by dimethylformamide(DMF) were investigated. The effects were evaluated by the atomic force microscopy(AFM) topographical changes and FT-IR spectrum analysis. PET films treated with DMF at
for several different treatment time(20, 40, and 60 min). AFM topography showed that, with increasing treatment time by DMF, PET surfaces became smooth due to the swelling phenomenon and the rigid structure changed into flexible state which was contributed to increase the surface area of PET films. FT-IR spectrum analysis showed that DMF and molecular chains of PET interacted each other via their polar carbonyl groups and that DMF also affected the out-of-plane bending vibration mode of phenyl ring of PET.
