  • The purpose of this study was to examine the outdoor sportswear purchase behavior, outdoorwear sportswear brand preference, functional fabric awareness, and benefits sought. The research was performed through in-depth interview during February to March 2011. Data were collected from 10 consumers who had purchased outdoor sportswear and experienced camping in 6 months. First, the results from study showed that functionality/comfortability, design, color, and brand name were important factors in selecting outdoor sportswear. Offline stores were the main place to purchase, however, internet shopping mall and portal online community were another shopping channel as well. Second, respondents preferred imported outdoor sportswear brand to national brand. According to the study, the respondents trusted the imported outdoor sportswear quality based on the brand name, value, and brand history more than national brand. Third, consumers who had low functional fabric awareness were more likely to evaluate apparel products based on the brand name. Knowledge levels for textile functions were high in elastic, UV protection, air permeable, and antibacterial properties. The essential features for camping were water absorbing and quick dry, water resistance, wind proof, UV protection, and fire retardant properties. Finally the results showed that there were two sportswear benefit soughts: functionality and status ostentation.

  • Effect of fixation methods and relaxation treatment on the flame retardant(FR) and physical properties of MDPP/HMM treated cotton weft-knitted fabrics were studied. Combination of four different fixation methods - relaxation, swelling agent treatment, pad dry cure fixation, and wet fixation - were applied to flame retardant finish of cotton weft-knitted fabric with MDPP/HMM. As the results, 1. Swelling agent and wet fixation method helps FR agent penetrate the fiber efficiently. Interlock showed relatively higher values of LOI than single jersey. 2. Interlock showed relatively higher values of bending rigidity(B), shear rigidity(G) and coefficient of friction(MIU) than those of single jersey before and after flame resistant treatment. 3. An increase in internal volume of cotton fiber by relaxation treatment increased the bending rigidity(B), shear rigidity(G) and compressional energy(WC). 4. The cotton weft-knitted fabric treated wet fixation, which crossliked FR agent efficiently, showed higher bending rigidity, shear rigidity(G) and lower compressional energy(WC). Retention of swelling ability of cotton weft-knitted fabrics treated with MDPP/HMM, which increased the internal volume of cotton weft-knitted fabric, showed lower bending rigidity.

  • This study examined the use of cutinase and lipase to process cotton/polyester blend fabric. Optimum treatment conditions for cutinase and lipase were investigated for cotton/polyester blend fabric. The properties of enzyme-treated fabrics were evaluated and compared in optimal treatment conditions. In addition, the possibility to provide an enzymatic finishing on blend fabrics using mixed enzymes in a two-step process were studied. The weight loss of cotton/polyester blend fabrics with Triton X-100 was 0.8% and the dyeing property of blend fabrics with calcium chloride increased by a factor of 1.2. The use of two enzymes in combination with cutinase and lipase in the presence of auxiliaries resulted in a cotton/polyester blend fabric weight loss of 0.8%. In addition, the dyeing properties of cotton/polyester blend fabrics improved by a factor of 1.5 and the moisture regain of cotton/polyester blend fabrics improved by a factor of 1.16. However, no marked loss was observed in tensile strength. The surface morphology of cotton/polyester blend fabrics is modified through a two-enzyme treatment. The treatment of cotton/polyester blend fabrics with cutinase and lipase maintains cotton strength and improves the moisture regain of polyester fabrics.

  • In this study, we investigated the dyeing properties of the ultra-fine nylon suede non-woven fabric with Sulphur black dye regarding to the effect of dye concentrations, reducing agent contents, sodium carbonate contents, antioxidant contents, immersion temperature and exposure time in air by pad-steam process. The optimal conditions of dyeing for the ultra-fine nylon suede non-woven fabric were determined with dye concentration of 30% o.w.f., reducing agent content of $9{\sim}13g/{\ell}$, sodium carbonate content of $1{\sim}4g/{\ell}$, antioxidant content of $1{\sim}5g/{\ell}$, immersion temperature of $70^{\circ}C$, exposure time of 20 minutes in air and immersion time of 1 minute, respectively. Meanwhile, the colorfastness to washing, the colorfastness to light, and the colorfastness to perspiration for dyed ultra-fine nylon suede non-woven fabric were achieved in the range of 4-5 grades. The formaldehyde and arylamine were not detected on the ultra-fine nylon suede non-woven fabric by KC tests.

  • Even though corrugated boards are the most common packaging materials for agricultural products, conventional corrugated boards are not able to maintain the freshness of agricultural products. In order to overcome the limitations of conventional corrugated boards, a new hybrid corrugated board-composed of linerboard, a corrugating medium, and non-woven fabric-was designed to possess antibacterial, high porous and shock-absorbing properties. In this study, we compared the physical properties of non-woven fabric to those of the base papers of conventional corrugated boards and developed a new adhesive system as a first step toward manufacturing the hybrid corrugated board. We found that the non-woven fabric, which had relatively high elongation, was applicable in the corrugated board process, and that the manufacturing conditions must be controlled in order to prevent the break of the non-woven fabric. The mixture of starch and styrene-butadiene (SB) latex showed high adhesive strength, but the addition level of SB latex should not exceed 30% in starch solution.

  • A new textile material, poly(trimethylene terephthalate) polymer, has been introduced to the textile industry. The structure of PTT is similar to the PET, while the tensile deformation and subsequent recovery property is better than that of PET. In this study, the physical and mechanical properties of textile woven fabrics made of PTT, PET, and nylon 6 yarns as the filling yarn were determined using the Kawabata Evaluation System (KES), including tensile, bending, shearing, compression, and surface related parameters. On top of these measurements, the subjective ratings by evaluators were performed on the fabric samples. From the examination of the stress-strain behavior of the yarn specimens focused on the recovery mode, it was evident that the PTT specimen developed lower stress at 3% elongation. The subsequent recovery curve showed that the PTT has less stress-decay rate than the other specimens, implying that the recovery behavior of the PTT is recommendable for the end-uses including stretchable textile materials, sports wears, etc. The KES bending rigidity(B) value of the PTT sample fabric was lower than that of the PET sample fabric. Subjective evaluation of the fabric samples by the evaluators on the descriptive word pair "soft - not soft" showed similar tendency with the KES B determination of the fabric samples.

  • Tactel(Nylon66) union fabrics were woven with the specification of 70d/34f nylon as warp for sport wear jacket. Weft yarn has three types; 100% cotton yarn, nylon core-spun yarn and nylon-polyurethane covering yarn as weft. Fabric structers were plain, twill and satin weave structure with the air jet loom. The mechanical properties of 8 fabrics were measured with KES-F and primary Hand Values and Total Hand Values were calculated. The results of the study were as follows: 1) There was little difference among LTs of N/CM fabric groups. RT of the fabrics with CM100's was bigger than that of fabrics with CM80's, resulting that the fabrics with CM100's have better formability. In terms of weaving structure, twill fabrics have shape deformation. 2) In comparison of RTs with weft yarn type, RT of N-PU covering yarn was the highest, followed by Nylon core-spun yarn and cotton yarn. Thus, the fabric with N-PU covering yarn has better stability of shape deformation. 3) Stretch yarn could express an excellent silhouette formation and twill and satin structures were better structure to make curvature on human form. 4) 2HG/G value of nylon core-spun fabrics was larger than that of N/C fabrics, but the silhouette formation of N/C fabrics was excellent. 5) The RC of N/PU was the highest, followed by N/P, and N/CM. 6) Koski of N/PU fabrics was the highest, Numeri of N/PU and N/Co-I were relatively higher than the others. THVs of N/CM-IV and N/CO-II were lower than the others, resulting that, twill structure was better than plain structure for a sport wear uses.

  • The purpose of this study was to obtain drape information and objective texture of fabrics easily and quickly by using a constructed fabric database. For the construction of the fabric database, 287 woven fabrics were examined by using the CLO fabric kit, KES-FB system, and drape test system. The k-means cluster analysis method was used to classify the fabrics into 7 grades. After correlation analysis of the fabric properties for each experiment, similar properties of the CLO fabric kit and KES-FB system were chosen, which were then designed to extract similar fabrics from the database. It was confirmed that inferring the drape information and objective hand feeling of fabrics was to some extent possible by extracting similar fabrics from the database. In this study, the primary hand and total hand value(THV) of KES-FB system, which was constructed by Kawabata and other experiments, were used to quantify the objective hand feeling, because they are the most widely used. However, these standards can be changed over time; in order to be applied within the clothing industry, these standards may have to be changed to some extent. Moreover, it is notable that although objective hand feeling cannot be expressed in the 3D virtual costume program, it can be easily derived from the constructed database. Additionally, it is expected that the existing 3D virtual costume program will express the costumes more realistically by improving these results.

  • In this study, a cotton knit was dyed with elm bark extract; subsequently, the dyed fabric was measured according to the types of mordants and the preprocessing cationizers used. Additionally, antibiosis against super bacteria was examined. The results follow. First, the color of the dyed cotton knit appeared reddish and yellowish for fabrics treated with non-mordants and mordants. When preprocessing with a cationizer was conducted, the dyeing properties were the best. Second. even when mordants were not used for dyeing, color fastness after washing, sweating, and rubbing was generally good Grade 4 and 5. Color fastness after exposure to sunlight was the best Grade 4 for fabric prepared with ferrous sulfate as the mordant. Third. as for antimicrobial properties, or resistance to super bacteria, the growth of bacteria was suppressed in a meaningful way for fabrics treated with non-mordants and mordants, compared to the control group fabric. The dyeing methods with the most powerful antimicrobial effects were dyeing after preprocessing with a cationizer and preparing fabric with copper sulfate as the mordant. The results stated above show that in case of dyeing with elm bark extract, preprocessing of the cotton knit with a cationizer and dying with copper mordant displayed high levels of antimicrobial properties that were useful for resisting super bacteria. Of these the dyeing properties were the best when preprocessing with a cationizer.
