This study explored the product attributes Vietnamese mothers consider for the purchase of children's wear, the differences of product attributes between groups with different levels of conspicuous consumption, and the extent to which the Korean wave affects the purchasing behavior of children's wear brands. The results are as follows. First, the product attribute that Vietnamese mothers consider most when purchasing children's clothes is the comfort in physical activities. Fabric type and quality, sizing and fit, durability, color, child suitability, design, cutting and construction, price, fashionability, and maintenance and laundering are the other attributes (respectively) that influence the purchase of children's wear. Second, the high conspicuous consumption group considers brand, maintenance and laundering, durability, the reactions of others, and fashionability significantly more than the low conspicuous consumption group. Third, the purchase intention of Korean children's wear brands is affected by the perception of the Korean wave than the influence of the reference group or the tendency of conspicuous consumption. The results show that low prices and practicality were important considerations for children's clothing purchases by Vietnamese mothers; however, brand name and fashionability were more powerful predictors for the high conspicuous consumption group. Those with a high perception of the Korean wave also had a higher intention of Korean children's wear brand, which is indicative of the halo effect of the Korean wave. Thus, Korean children's wear brands that plan to enter the Vietnamese market should make active use of the Korean wave.

In this study, we reviewed the color changes accompanying the laundering, wash fastness, and abrasion fastness of chitosan-treated cochineal-dyed fabrics. The treatment methods were classified into two based on the chitosan treatment: (Method 1): fabric specimens were pre-treated with chitosan prior to the dyeing procedure in salt form. (Method 2): the state of chitosan acid salt formation, coated on the yarn surface, was destroyed and neutralized prior to the dyeing process. The changes in the chitosan treatment methods bear more important meaning in view of the durability. In Method 1, it is highly likely for the chitosan to be detached from the surface by water during laundering since the chitosan is coated as acid salt state. In Method 2, the resistance d the chitosan to water was supposed to revive since the chitosan would return to its original state. Differences in the resistance of the chitosan treatrrent, however, according to the Method 1 and Method 2, fell short of our expectations. In Method 2, the wash fastness did not improve as we expected since the bond between the fibers comprising fabric specimens and the chitosan is not high even if the chitosan itself has high resistance to water.

Effect of disperse dyeing on flame retardant finishing of PET fabrics via UV curing using three UV curable phosphorous-containing methacrylates and ammonium polyphosphate(APP) was investigated. The dye fixation and flame retardancy of PET fabrics did not change significantly with excellent durability to five laundering cycles irrespective of the dyeing and finishing sequence. However, the flame retardancy of Pekoflam-treated fabrics was lower than that of the UV treated and decreased substantially when heat treatment was carried out before the dyeing. The dyeability of the flame-retardant PET fabrics was not affected in the case of UV curing of the methacrylates alone. However, UV finishing after the dyeing caused significant decrease in K/S and ${\Delta}E$ due to changed refraction and inherent color of surface coating of the UV curable monomers and APP. Whereas the heat treatment with Pekoflam decreased both color fastness to laundering and sublimation, surprisingly the UV finish of PET fabrics before and after the dyeing increased the color fastness probably resulting from the presence of photopolymerized surface layer on the fabrics.

This survey intends to understand the opinion and status on preschool students' uniform wearing for the purpose of new style development. The results from this study will serve as an activator of related industry. The merit of uniform wearing in these students was recognized primarily as: (1) students can have pride in the schools they attend; (2) they need not worry about clothes to wear every morning. The disadvantage of uniform wearing derives from: (1) students' personality is hardly expressed by uniforms; (2) difficulty in uniform selection suitable for varying weather conditions. This disadvantage felt by their parents suggests the lack of personality expression and appropriate body temperature control. The most prevalent opinion for preference and future improvement points was the consideration of physical activity in children. This indicates that they prefer uniforms rendering minimal restriction on body movements. Other Improvement points stress the activity, uniform laundering and care, convenience in on and off, insulation, colors, design and durability.

UV-curable water-repellent finish was carried out to impart one-side repellency to the PET fabrics using a formulation of a UV-active fluorocarbon agent and a water soluble photoinitiator. The aqueous formulation was padded on the PET fabrics and it was subsequently UV-cured. The unirradiated side of the cured fabrics was made to wetteable to water by the prolonged UV/ozone irradiation. The influence of photoinitiator concentration, agent concentration and UV energy for photodegradation on the performance of the finished fabrics were investigated. The difference in the functional property of front and back sides was examined by measuring water repellency at each side of the treated fabrics, which resulted in four rating difference between two-side. The UV-cured and photodegraded PET surfaces were characterized by ATR, ESCA and FE-SEM.

Combat uniforms require higher tensile and tear strength than civilian products, and applied infrared reflectance from the recently developed nighttime fluoroscopy equipment to ensure combatant survival at night. Unlike other uniforms for civilian use, combat uniforms require durability against laundering because they may not be supplied again, once originally provided. Therefore, this study examined the changes in strength and changes in infrared reflectance after multiple washing of combat uniforms. The experiment confirmed that the strength change after the washing of combat uniforms 15 times was maintained in the same manner as the result after washing five times. In the case of infrared reflectance, the difference in reflectance after multiple washing treatments was greater than that in the case where washing was not performed. Therefore, although the durability in the case of combat uniforms is strong, it is necessary to maintain a reflectance higher than a certain level through the development of materials and the development of dyes.

The purpose of this study was to evaluate the effect of various knitted fabrics of sports socks on their properties of hygiene and stability. Seventeen men\`s sports socks to represent five groups with different fiber content, knit structure, yarn fineness, and finishing were used. Properties of hygiene and stability of socks were determined. The results were as follows ; 1. Evaluation of Water, vapor and heat transport properties in socks with varing fiber content showed that cotton 100% socks had the highest drop absorbency, wickability, water absorbency and water retention. Polypropylene 100% socks had an excellent wickability and moisture permeability. Acrylic blend socks had the highest thermal resistance. 2. The greatest knit stretch and knit growth of socks having lower power were found to be with cotton 100% socks had the lowest stretch. Acrylic blend socks had a excellent stretch but low fabric growth, which could give a good fir sensation during wear. 3. The commerical antimicrobial finished socks showed excellent durability after repeated cycles of laundering. 4. Length and width shrinkages were found in all laundered samples during initial cycles due to rearrangement by mechanical relaxation. Shrinkages showed no further changes and reached equilibriums after 5 cycles. Cotton 100% or cotton blend socks showed lower dimensional stability than other socks during fabric care.

The flame-retardant (FR) treatments of wool fibers using Hexafluorozirconate/titanate salts and tetrabromophthalic anhydride can cause skin irritation and gas toxicity due to Zr and Br compounds respectively. A water-soluble polyfunctional cyclophosphazene derivative, synthesized through substitution reaction of Hexachloro cyclophosphazene and N-[3-(Dimethylamino)propyl] metacrylamide, was applied as a durable flame-retardant for wool fabrics. Also, a crosslinked structure was introduced to improve washing durability of the FR-wool, up to 10 laundering cycles, using Acrylamide(AAm) and Triacryloylhexahydrotriazine (TAHT) as a comonomer and a crosslinker respectively. The mole ratios of the TAHT and AAm concentrations compared to the Dichloro tetrakis{N-[3-(Dimethylamino)propyl]methacrylamido} cyclcophosphazene (DCTDCP) were optimized to 1.33 and 7.5 respectively. In addition, the pyrolysis and combustion properties of the FR wool were assessed using LOI, TGA and microcalorimetry suggesting a solid-phase FR mechanism.

In order to reduce the safety risk of forestry operations, this research was conducted to examine the suitability of chainsaw protective pants after repeated laundering, testing four different products that are currently used in hand-held chainsaw operations. Laundering was repeated 10, 20, 30, 40, and 50 times. After washing, we measured the shrinkage ratio of 17 measurement positions mostly affecting the safety of forest operations and suggested the expected safety life cycle of chainsaw protective clothes. The results showed that most of the products have only one measurement position where the standard shrinkage ratio (<6%) was exceeded after 20 washings, and that the lateral direction of measurement positions shrank more than the vertical one. The numbers of repeated launderings and measurement positions were found to be significant factors influencing the shrinkage ratio (p<0.05). In the shrinkage rates for 17 measurement positions, there were significant correlations between five of the measurement positions (a, b, g, j, and n) and the number of repeated launderings (p<0.05). Therefore, the results suggest that about 10 months would be suitable for an adequate safety lifetime for chainsaw protective pants. The relationship between the number of repeated launderings and the measurement positions will be further analyzed in detail to examine the durability of chainsaw protective pants.

This study was conducted to analyze the wearing condition on gloves for pilots and to suggest the developments for pilot gloves design. This survey was performed with 99 pilots and the questionnaires included items about discomfort, materials and problems when wearing pilot gloves. The respondents felt uncomfortable on the finger tip, the hollow area of the hand and the end of thumb when they move their hands with the gloves. They replied that the finger length, palm length, and circumference of the fingers did not match well. Also they complained there was severe abrasion in the tip of the thumb, finger tips and the middle of the palm of the gloves. The result of these analyses supports the following suggestions. It is necessary to improve durability by applying the additional materials to the severely worn parts. Punching on the glove materials could improve sweat rate and ventilation, and careful washing should be accompanied to prevent the occurrence of linters and transformation after laundering. And it is needed to prepare an accurate and more diversified size system and to design the gloves fitted to the individual hands. With these in mind, it is required to propose solutions for pilot gloves with reference to the survey results in order to design appropriate pilot gloves in terms of movement, size and material. It was concluded that an analysis of the wearing condition and developments are useful for ergonomics pilot gloves design.
