Jeon, Han-Yong ; Chung, Youn-In ;
Textile Science and Engineering, volume 43, issue 4, 2006, Pages 153~158
Long-term performance of geogrid should be dependent on the mechanical behaviors during the service periods. Mechanical properties of geogrids are mainly influenced by not only creep deformation behaviors at the constant confining load and temperature but also stress relaxation behaviors at the constant strain and temperature as viscoelastic deformation. In this study, new concept mechanical model was suggested and applied to analyze the long-term performance of geogrid with instantaneous and asymptotic responses. Experimental results of creep and stress relaxation tests of geogrids were compared each other to verify this suggested mechanical model.

Textile Science and Engineering, volume 43, issue 4, 2006, Pages 159~165
Strain compatibility was applied to examine the limit of long-term allowable strength determination for geostrip as geosynthetic reinforcement. Creep test was performed for geostrip reinforcements according to SIM(step isothermal method) to obtain isochronous curve. Through the isochronous curve of geostrip reinforcements, the long-term allowable tensile properties of geostrip reinforcements was interpreted and analyzed.

Polyaniline(PANI)/pelyacrylronitrile(PAN) nanoweb was obtained by electrospinning and in situ polymerization. The electrospinning dope was prepared through dissolving purified PAN in dimethylsulfoxide. To obtain PAN nanoweb of the proper morphology for PANI in situ polymerization, the dopes were electrospun with varying voltage, tip-to-collector distance(TCD) and dope concentration. Then, PANI, one of the conductive polymers, was polymerized on the surface of PAN nanoweb by in situ polymerization. The relationship between the electrical conductivity of PANI/PAN nanoweb and several polymerization variables was investigated. Aniline concentration, diffusion time, polymerization time, and molar ratio of aniline to oxidant (ammonium persulfate) were handled. The electrical conductivity was measured by 4-point probe method.

When glyoxal was used as a crosslinking agent and aluminium ammonium sulfate as a catalyst for durable-press finishing, coreactants and additives to minimize the decrease of physical properties of durable-press finished cotton fabrics were studied. Also, optimum conditions such as coreactant/glyoxal mole ratio, the concentration of additives and the effects of one-bath and two-bath were investigated. Under the optimum concentration of DEG, the whiteness and strength retention of the fabrics treated with glyoxal/DEG/additive mixtures were increased while wrinkle recovery angles were decreased significantly. Under the optimum concentration of each additive, cotton fabrics were treated with various impregnation time in order to find the effect of two-bath method. The whiteness of cotton fabrics was increased by two-bath method, and wrinkle recovery angles were decreased either slightly or unchanged while the strength retention was not affected.

This study was performed to determine the feasibility of electrolytically produced NaOCl solution for the treatment of dyeing wastewater discharged from textile industry. Industrial dyeing wastewater was pre-treated by PAC coagulant and the optimal pH and dosage for coagulation were 6.5 and 0.05 v/v%, respectively In this pre-treatment process
, color and suspended solids removal efficiency were 66%, 91% and 85%, respectively. After pre-treatment by coagulation, NaOCl solution made by electrolysis was used for the treatment of industrial wastewater. The optimal mixing ratio with NaOCl solution and dyeing wastewater was determined to be 1:5 at pH 5.0 and in these conditions, color and removal efficiency were 99% and 88%, respectively. From these results, we can expect that NaOCl solution produced by electrolysis with salt of a lower price can be used for the treatment of industrial dyeing wastewater conveniently and effectively, and can overcome disadvantage of a commercial NaOCl solution with a bad storage and delivery properties to decreas oxidation ability.

Hydrophobic surfaces of cellulose acetate(CA) fabrics were modified to give more hydrophilicity via
irradiation. The surface change of chemical structure and composition were investigated by ATR and ESCA analysis. The UV irradiation treatment caused ester linkage of the acetyl groups to break down and new photo-oxidated products were generated as indicated in subtracted ATR spectra and
. Also degree of acetylation of the irradiated CA fabrics decreased with increasing UV energy. It was found that the dyeability of the modified acetate remarkably improved particularly toward cationic and reactive dyes, while disperse dyeability of the modified fabrics decreased noticeably at the irradiated surface. Effect of change in various dyeing conditions including dye concentration, dyeing time and temperature on cationic dyeing were assessed to find optimal dyeing condition. The colorfastness of the acetate fabrics to laundering and rubbing was good enough in spite of surface coloration of the acetate fabrics inevitable in the UV treatment and subsequent dyeing.

Growing drop technique has been developed for measuring the dynamic behavior of drop at the exit of a fine capillary where a drop grows. In this study, the system was designed to simulate the electrospinning process without applying a high voltage to understand the dynamic behavior of PVA solution before ejecting a fluid jet. The system associated with Image analysis technique and numerical analysis method has been developed. Important parameters of the drop formation were extracted by programming image analysis techniques such as fill boundary method and chain cord algorithm. To obtain statistically meaningful data, numerical analysis techniques were programmed. The diameter, volume, contact angle and velocity of fluid head of PVA solution at the exit of a fine capillary have been measured and calculated with various hydrostatic pressures. The integrated system of image analysis and numerical analysis methods has been successfully used to investigate the effect of the hydrostatic force on drop formation.
Change in Physical Properties of PTT and PET Filament Yarns Due to Heat Treatment
Kim, Il-Rae ;
Textile Science and Engineering, volume 43, issue 4, 2006, Pages 196~200
Change of physical property for dry heat treated DTY filament yarns was studied by investigating the change of molecular structure. Tensile strength, elastic recovery, and relaxation time roughly decreased with increase of heat treatment temperature. On the other hand, elongation and crystallinity increased with heat treatment temperature. PTT showed relatively high increase of crystallinity compared to PET. Minor increase of tenacity was found near
of PTT. It was found that the elastic recovery is closely related to the number of Gaussian chain segment for rubber-like deformation. The relaxation time for U near 79 showed higher inclose than that of PET. In the estimation of relaxation time, fractional Maxwell model rather than Maxwell model simulated more reasonable value. Based on these results, it was deduced that physical cross-links such as entanglements of polymer chains formed when crystal is newly formed by the rearrangement of polymer chains.

Polyester microfiber has usually greater dye uptake than normal denier polyester fiber at the same dyeing condition. Though polyester has high dye uptake, dyed microfiber fabric has not only low visual colour depth but also poor washing fastness property. In order to improve this dyeing property, poly(ethylene terephthalate/trimethylene terephthalate)(ET/TT) was synthesized with various TT content using DMT process. The feed ratio of TT was varied from 5-30 mol%. The content of TT unit in P(ET/TT) was higher than the feed ratio of TT. The physical properties, dyeing properties, and wet fastness of P(ET/TT) were investigated. Melting
and glass transition
of P(ET/TT) decreased with increasing content of TT unit. P(ET/TT) could be dyed at lower temperature than homo PET with increasing TT feeding content. Alkaline dissolution behavior of P(ET/TT) was also examined as a function of TT content.
