A series of
composite sols have been prepared by the hydrolysis of tetraethyl orthosilicate (TEOS) and titanium (IV) isopropoxide dissolved in isopropanol which was controlled by HCl addition. The maximum amount of
for suitable fiber formation was about 50 mol% in
composite inorganic fibers. The SEM, TEM, and FT-IR results showed that the surface morphology and crystalline phase of the electro spun composite micro/nanoscale
fibers were strongly affected by the content of
and calcination temperature. The SEM and TEM images reveal that the fibers had diameters varying from hundreds of nanometer to 2 micrometer. The photocatalytic activity of composite inorganic fibers was evaluated by decomposition of methylene blue, acetaldehyde, and formaldehyde in waste water which are recognized as volatile organic compounds (VOCs).

In this study, hydroxypropyl methylcellulose (HPMC) filaments were prepared by the wet spinning process, and the coagulation behaviors of HPMC dope and the morphology of wet spun HPMC filaments were investigated. THF, acetone, and iso-propanol showed a partial coagulation strength for HPMC dope though they did not produce a filament form. On the other hand, a high temperature water could coagulate the HPMC dope due to the gelation character of HPMC solution. However, the temporarily coagulated HPMC filament returned to a solution state when it came out of the coagulation bath. This problem, due to the reversible gelation behavior of HPMC, could be solved by adding salts in the water (coagulant). As the salt concentration increased in the coagulant, the coagulation strength was improved resulting in a reduced fiber forming temperature. Furthermore, ammonium sulfate was turned out to be the most effective salt to enhance the coagulation of HPMC in aqueous salt solution. The thermo-rheological measurements revealed that ammonium sulfate was the most effective in reducing the flocculation and the gelation temperatures among salts tested. The HPMC filament could be produced finally with the help of second coagulation bath containing organic solvent. Among the organic solvents, isopropanol was the best coagulant yielding the highest post drawing ratio of HPMC filament. The SEM observation indicated that the wet spun HPMC filament had irregular surface and cross section. The surface of HPMC could be smoother when the salt concentration was reduced to 8%.

Textile Science and Engineering, volume 46, issue 5, 2009, Pages 261~268
The effect of fiber content and fiber length on the tensile and flexural strength of basalt chopped fiber reinforced cement composite was investigated. The tensile and flexural strength of the cement composites were effectively improved by the addition of basalt chopped fiber. The cement composite reinforced with shorter fiber length showed the higher tensile strength. On the contrary, the flexural strength was increased with the increase of fiber length. Also basalt chopped fiber in saturated
solution which is similar to the alkaline environment of cement hydration exhibited very low weight loss and high stability even after 3 months of immersion.

The purpose of this study was to determine the effects of laundering on the shrinkage and elasticity of cotton/spandex fabrics, in which one group was enhanced 5%, the other group was 10%, the third group was 15% during tentering and the final group was not enhanced but dyed with a reactive dye. The laundering conditions were varied in washing temperature, drying methods and number of wash cycles. Shrinkage and elasticity as the extension and elastic recovery after stretching at a force of 15 N for cotton/spandex fabrics were investigated. The fabrics which were treated with greater enhancing during tentering, showed greater shrinkage, lower extension and less elastic recovery after repeated washings and dryings. The cotton/spandex fabric which was enhanced 5% during tentering showed the least amount of deformation after 20 washings. The greatest deformation of the cotton/spandex fabrics occurred after the first wash, but the increases in shrinkage and elasticity were reduced as the number of wash cycles increased. The fabrics which were washed at
and air dried showed lower shrinkage and lower extension with the force of 15 N than the fabrics washed at
and dried in the tumble dryer. This showed that drying temperatures had a greater affect on the deformation of the cotton/spandex fabrics than the washing temperatures.

A drum-type washing machine washes more effectively and consumes less water than the other type washing machines. We need to find the most effective washing conditions to increase the rinsing performance with the reduced amount of rinsing liquid in the drum-type washing machine. In order to determine the most effective washing conditions on the rinsing performance, we have considerd the following factors: main-washing liquid ratio, spin-drying time, spin speed during spin-drying, rinsing liquid ratio, number of rinses, rinsing time, and load of fabric. We also compared the rinsing performance between a controlled wash cycle of the drum-type washing machine and a standard wash cycle of a commercial pulsator-type washing machine. We measured the electrical conductivity of the liquid which was extracted from the fabric after the main-wash and each number of rinse. Increasing the number of rinses was the most important factor in increasing the rinsing performance. Then the rinsing liquor ratio, the main-washing liquid ratio, the load of the fabric, and the spin speed during spin-drying had a decreasing effect on the rinsing performance in that order. In our research the rinsing time and the spin-drying time did not show meaningful difference. The rinsing performance of the drum-type washing machine with a lower rinsing liquor ratio could be the same as or better than that of the pulsator-type washing machine because of the lager drum radius and a much higher spin speed.
Fiber Properties of Needle-punched Nonwoven Fabrics on Air Filter Applications

Various fiber types consisting of a single nonwoven fabric were investigated to provide a combination of good strength and filtration characteristics. Polyester staple fiber (PSF) 3, 6, and 15 denier, low melting PSF (LM-PSF) 4 denier, 3-ball-type, non-circular shaped, PSF 2 denier (NC-PSF), and splittable micro-PSF 2 denier (SM-PSF) that were divided into 8 pieces by needle punching force were used for investigation. The effects of the enormous increase in the surface area and the reduction in pore size due to the use of finer fibers are reported. As the fiber denier size was reduced, the dust arresting efficiency increased and the air permeability decreased. The dust arresting efficiency also increased with increasing SM-PSF content.

The effect of sericin on the crystallization and gelation of fibroin was studied. We used urea-mercaptoethanol for extraction of sericin from silkworm cocoons. The degradation of sericin during extraction could be minimized and the molecular weight of sericin was in the range of 10-400 kDa. Based on the result of time-resolved FTIR-ATR spectra, the crystallization of fibroin was retarded in the presence of urea-mercaptoethanol extracted sericin like as previously reported hot-water extracted sericin. The gelation time of fibroin was also delayed in the presence of sericin. Interestingly same delaying effect could be also observed when fibroin and sericin were immiscible. These results show that sericin might have more active role in the spinning process of silk fiber.

The optimization of the high shrinking process has been performed for the high performance wiping cloth having excellent performance, which is based on the microfiber composed of the nylon and polyester in the TFT-LCD industry. To satisfy the required performance as an industrial wiping cloth in the TFT-LCD area, the wiper has excellent dust removal ability. Oil and water absorbing performance has a less dust particle generated by the solvent and the anti-scratch property on the surface of LCD product. These requirements could be achieved by high shrinking treatment for a microfiber knitted fabric to the selected best conditions. In this study, 10% of benzyl alcohol concentration and
of heating temperature were selected as the best treatment condition through the experiment considering all the related parameters such as temperature, concentration of agent and used fiber type. Then, Shrinking, SEM, and tensile strength performance were analyzed and compared with that commercialized products, being widely used in TFT-LCD area.
