  • Physicochemical properties of a polymer surface significantly affect adhesion, wetting, and dyeing properties. In recent years, low temperature plasma technology has been widely used for surface modification of polymers. Surface fluorination by low temperature plasma treatment has been employed to improve the water and oily repellency of textile fabrics. However, very few results have been reported on soil release properties of the oxygen plasma treated textile fabrics. (omitted)

  • Shrink resist finishing of wool fabric was carried out with Monoethanol aminesulphite (MONAMIN BTN) shrink resist agent after chlorination with Dichloro isocyanuric acid (DCCA). The purpose of this study is to investigate the effect of treating conditions, such as concentrations of DCCA and MONAMIN BTN, pH of treating bath, dyeing times, curing times and temperatures, on dyeing property of wool fabrics. K/S values and fastness properties of dyed wool fabrics were measured. The K/S values of dyed fabrics were increased gradually with increasing concentration, and decreased with increasing curing time. The optimum dyeing time and curing temperature were 60 min and $140^{\circ}C$, respectively. Also it seems likely that the shrink resist finishing carried out at 3% (o.w.f.) of MONAMIN BTN and pH 7 of resin treating bath is effective in increasing K/S values. Light fastness of fabric dyed was very poor and the fastness of fabric dyed was not influenced by the treatment conditions.

  • Self-cleaning fabric is a fabric having a function of decotamination via photodecomposition of photocatalyst or wash-off of contaminants on the superhydrophobic surface. TiO2 is the main photocatalyst for this purpose, but it only functions under UV light which is only a little portion of sunlight, compared to visible light. In this regard, this study aims to investigate Fe-doped TiO2 for improved photodecomposition from visible light sensitization to apply self-cleaning finishing of PET fabrics. Moreover, the Fe-doped TiO2 treated PET fabric was further treated with hexadecyltrimethoxysilane to provide superhydrophobicity on the PET fabrics. As a result of this dual treatment, the prepared fabric exhibited excellent photodecomposition of methylene blue with 96.96% in 12h under sunlight and superhydrophobicity with water contact angle of 166.5° and roll-off angle of 7°. This suggested that the excellent self-cleaning functions can be privided to PET fabric via Fe-doped TiO2 and hexadecyltrimethoxysilane treatment.

  • This study aims to establish the optimal environmental conditions for storing textile products. Four textile products (cotton, wool, nylon, cotton/polyurethane) were used to produce experimental fabrics according to artificial contamination and washing conditions. Each fabric was subjected to three environmental conditions (A: 20-25℃/20% RH, B: 20-25℃/50% RH, C: 30-35℃/65% RH) for 4-12 weeks. Changes in textile characteristics include tensile strength, wrinkle recovery rate, and odor intensity. Results show that the change in tensile strength for the four test fabrics slightly decreased with a storage time of 4 to 12 weeks. The wrinkle recovery rate of the fabrics was the lowest under the C condition. UV exposure causes a substantial decrease in the tensile strength of the textiles. The change in odor characteristics was the highest for the odor intensity in the C condition. For storing textile products for sustainable management, it is desirable to maintain a temperature of 20 to 25℃ with a relative humidity of 50% RH or less and to provide ventilation in an enclosed storage space that can also block UV rays.

  • Recently, eco-friendly processing has been focused in the textile industry in order to reduce environmental pollutions. Applications of enzyme technology to the textile industry are an example of more environmentally compatible processes. However, there is not enough quantity of referring to denim fabric subjected to enzymatic treatment. In this study, depending on pH, temperature, cellulase concentration, and treatment time, the weight loss of denim fabrics was examined. Characteristics of enzyme-treated fabrics were measured by tearing strength, stiffness, and K/S values. The effect of a non-ionic surfactant (Triton X-100) on characteristics of the enzyme-treated fabrics was evaluated. The cellulase treatment condition on the cotton fabric were optimized to pH 6.0, $50^{\circ}C$, 1%(o.w.f.), and 60minutes. Characteristics of denim fabrics by cellulase treatment in the presence of Triton X-100 did not improve because Triton-X inhibited the activity of enzyme.

  • This study examines the scouring effect of pectinase on ramie fabric and influence of sodium sulfate as an activator for pectinase. The scouring effects were measured by the weight loss and pectin contents. SEM, weight loss, stiffness, moisture regain and dye ability of ramie fabric teated with pectinase/sodium sulfate were also measured. When ramie fabrics were desized with $\alpha$-amylase, the optimum conditions were pH 6.5 at $60^{\circ}C$ for 80 min with 1%(o.w.f) $\alpha$-amylase concentration. When ramie fabrics were scoured with pectinase, the optimum conditions were pH 8.5 at $55^{\circ}C$ for 30 min with 10%(o.w.f) pectinase concentration. Addition of sodium sulfate improved enzyme activity significantly, which increased proportionally with increasing sodium sulfate concentration. When 50 g/l of sodium sulfate was added, the surface became cleaner compared to the enzyme treatment without salt: weight and tensile loss, moisture regain and dyeability of the treated fabrics increased, while pectin contents and stiffness decreased. Therfore, sodium sulfate was effective activator for the pectinase treatment of flax fiber.

  • The object of this study is to develop textile designs and fashion products based on the cultural resource of Jeju Bangsatop, which means a stone tower preventing misfortune and driving out evil spirits. The field surveys of 32 Bangsatops located at 17 villages in Jeju were conducted. As a result, unlike stone towers located in other regions, Jeju Bangsatops made with basalt. In addition, wood and stone birds, Dolhareungbang, and other sculptures are built on the tops. Jeju Bangsatops were classified into four types based on the body form of the tops: Conical, truncated conical, trapezoid, and irregular shaped Bangsatops. Jeju Bangsatops located in a area or a village are symmetrically arranged in direction of south and north, left and right, east and west, or face to face. The conical, truncated conical, and irregular shaped Jeju Bangsatops which are designated as folk cultural properties or which have the unique sculptures of stone birds and the statues of Dolhareungbang built on the tops were selected as motifs for textile pattern design. The 4 basic patterns of Jeju Bangstops were designed. The six creative textile designs were developed by the various repeat arrangements of the basic patterns and were printed on oxford cotton fabrics by digital textile printing (DTP) method. The sixteen products of wallets, bags, hats and shoes were actually made with the DTP fabrics, the DTP fabrics which were naturally dyed in gray and blue colors, or the DTP fabrics which were redesigned with textile crayon. Therefore, it is confirmed that Jeju Bangsatop could be very useful as a motif for the development of cultural products focusing on Jeju tourism souvenir market.

  • The electrolytic water(EW) has been used in agriculture, medical, semiconductor, and household fields. However there has been no use of EW in the textile process so far, because the application in the textile industry has been needed a large amount of EW in real process conditions. Recently, we have got electrolytic oxidation water(EOW) and electrolytic reduction water(ERW) by development of a electricity electron technology. And, the productivity of EW manufacture apparatus is arrived to large capacity. As a result, the application of EW could be possible in the textile industry. In this study, to confirm the possibility of application of EW, we scoured and hydrolyzed PET fabric using the EW. It was possible that the application of ERW for the scouring and hydrolysis of PET fabrics in the textile process.

  • The results of the analysis of dyed rayon fabrics treated with persimmon juice by padding are as follows. Rayon fabrics were dyed repeatedly with persimmon juice by a padding mangle for the development of dyeability. The merits of padding-based dyeing were easier color reproduction (versus traditional hand dyeing) of hard to obtain colors and color fastness to light and laundering. The add on weight increased with the number of padding times, and the color of the dyed fabrics had red-yellow colors with low brightness and high chromatic colors. Properties of fabrics treated with persimmon juice were: $2^{nd}$ level of light resistance, $4^{th}-5^{th}$ perspiration fastness levels, rubbing fastness, and $3^{rd}-4^{th}$ washing fastness levels. Dyed fabrics exposed to UV light have a deep yellow-red color that increased lightness and darken when exposed to sunlight. Rayon fabrics of a treated premordant indicated strong yellow colors, especially fabrics with Fe mordant indicated greenish red-yellow colors. The direction of the weft and warp increased and improved water-repellent qualities that increased with the number of dyeing padding times and persimmon juice; however, there was less anti-crease resistance. In addition, fabrics had good antibacterial activity and deodorization.

  • This study was carried out to investigate on the removal of oily and particulate soils from silk fabrics. Various kinds of solvents were used on the removal of two kinds of soils treated into the silk fabrics. The removal of oily soil was analyzed by liquid scintillation counting method, and the removal of oil and carbon particulate mixed soils was evaluated by measuring of reflectance on the surface of soiled fabrics with/without drysoap in solvent washing by Terg-o-tometer. The surfaces of fabrics were also observed by SEM before and after washing. The results obtained were as follows : oily soils were removed efficiently by various kinds of solvents regardless of kinds of silk fabrics in short washing time. The removal effect of solvents from the soiled silk fabrics were high in the order of isopropyl alcohol>trichloroethane>monochlorobenzene>ethylether>perchloroethylene. Oil and carbon particulate mixed soils could be efficiently removed by adding of drysoap in solvent washing. The removal of mixed soils were increased drastically with rinsing and increased drysoap. The removal of soils was more efficiently removed from degummed silk fabrics than from the raw silk fabrics.
