  • Recently, problems related to the natural dyeing have been addressed. Severer problems have been posed by the elution at metallic ions and dyestuff tram dyed fabrics. In order to prevent the elution tram the dyed fabrics, it is needed to improve the fastness. Especially, it is the most important measure to improve the fastness to perspiration in terms at human body safety. In this study, we employed chitosan pretreatment method bet ore the dyeing process, anticipating that the pretreatment might improve the fastness. We used Al, Sn, and Cu as mordants and investigated the fastness to light and perspiration of the chitosan treated and dyed fabric specimens. By the chitosan pretreatment, the fastness to perspiration improved, while the fastness to light did not.

  • Dyeing properties using natural material named Sasa quelpaertensis Nakai were investigated under various conditions such as fabric type, pH, concentration, temperature, dyeing time and dipping count. Sasa quelpaertensis Nakai is a unique material in that it is raised only at Halla mountain in Jeju island and is known to have healing effect. Overall, wool fabrics were better than cotton fabrics in all aspects of the dyeing properties showing reddish yellow. For the fastness properties, robbins washing and perspiration fastness were excellent but lightfastness was poor as expected.

  • 직물의 소리에 의해 유발되는 감성을 토대로 직물의 소리를 색채와 매치시키는 실험을 실시하여 직물의 소리를 색으로 변환해 봄으로써 시각과 생각에 의한 복합감성을 활용한 직물 디자인을 제안해 보고자 하였다. 의류소재 30개의 소리를 녹음하여 군집분석한 후 각 군집별로 섬유의 종류를 고려하여 총 6개의 소리를 선택하여 주관적 감성평가와 색 변환실험에 사용하였다. 직물의 소리는 섬유의 조성에 관계없이 주로 Blue, Purple Blue 그리고 무채색으로 표현되었다. 그런, wool은 Gr(grayish), silk는 Dk(dark), polyester는 Dl(dull), nylon은 Dk(dark)등의 차분하고, 안정되고, 점잖은 느낌의 색조로, cotton과 flax는 P(pale)와 Vp(very pale) 같은 부드럽고 가벼운 느낌의 색조로 표현되었다. 따라서 직물의 소리 감성을 설명하는 요소는 색상보다는 색조에 있음을 알 수 있었다.

  • In cotton fabric sizing the domestic material is normally starch finds itself more frequent uses than the PVA size does. In this study we have examined the effects of ironing temperature and washing temperature on the removal of sized PVA by washing and have got following temperature on the removal of sized PVA by washing and have got following results: 1. the removal of PVA is related approximately to the reciprodal of the ironing temperature. 2. the higher the ironing temperature, the lower is the removal of PVA; and if the ironing temperature is higher than 140C the removal of PVA decreases abruptly even if the washing temperature were still high. 3. The most appropriate washing temperature should be at least 75Cwhen the ironing is carried out at 100C the same holds for 80Cto 120Cand 90Cto 120C, respectively.

  • The purpose of this study is to investigate the preference and the use of the bedclothes. The data were obtained from market research of 12 department stores which were located in Seoul, Daegu and Busan, and from questionnaires completed by 356 women in Daegu area whose age was 20 years and older. The SPSS package was used for data analysis which includes frequency, percentage, X2test, ANOVA, and Scheffe test. Cotton was the most popular fiber for coverings and fillings. Color preference was in the order of pastel, non-chromatic, vivid, and white color and pattern preference was in order of floral, check, and stripe pattern. Practicality, color and fabric were the most important factors and price was the most unsatisfied factor when bedclothes were purchased. Also, information for bedclothes was obtained mainly through internet shopping, home shopping or catalog shopping.

  • The natural dyestuff, grape skin dye was manufactured from grape skin by boiling in 0.1% HCI solution, eliminating the sugar and powdering in freeze dryer. Cotton, wool, silk and nylon fabrics were dyed under several conditions using the manufactured grape skin dye to investigate the dyeability and color fastness. Dyeing was operated in acidic dyebath of pH 4 because the grape skin is anionic. The color of dyed fabrics were affected on temperature of dyeing solution. Under 80\^C, the color of dyed fabrics were red or violet, but changed to brown in laundering. Above 100\^C, the color were brown and safe in laundering. Dyeabilities on wool, silk, and nylon fabrics were good, especially silk fabrics were dyed deeper than others. Dyeability was developed with concenturation of dyeing solution. All the dyed fabrics were excellent in color fastness to crocking and laundering. Light fastness was low to moderate. The light fastness of dyed nylon fabrics were as poor as grade 1, but they could be improved to grade 3∼4 by aftertreatment with gallic acid.

  • Optimum dyeing conditions of green tea extracts were investigated toward nylon, cotton, rayon, and tencel fabrics. Affinity of green tea extracts was exhibited much higher onto nylon fabric than the other cellulosics. As for nylon, the adsorption was increased with the increase of dyeing temperature and optimum dyeing pH was around 4~6. Buildup property of green tea extract was good showing a linear relationship between concentration of the extracts and color strength of dyed fabrics within experimental range. Color fastnesses were good to excellent in general except to light.

  • Currently, as mordants, heavy metals are being used in dyeing process in order to improve dye uptake and dye fastness. These chemicals, however, are mostly harmful to human body and the environment along with the pollution by effluent. Traditionally, rice straw ash solution, lime, etc. have been used as mordants in order to improve the effects on dye uptake and color fastness of dyestuffs. The study of natural mordants would, therefore, be vital to the development and succession of our traditional dyeing methods. In this study, as a preliminary step toward the use of rice straw ash solution for the nautral dyeing using Caesalpinia sappan, several aluminum compounds were employed as mordants. When the purified aluminum compounds were used, on the basis of unmordanted cotton fabric, the K/S values of the pre-mordanted and simultaneously mordanted fabrics increased by 2 or 3 times, while those of the post-mordanted fabrics decreased.

  • The purpose of this study was to identify the utility value with material of natural dyeing and to examine the dyeability and antibiosis of fabrics dyed with Solanum nigrum extract. The results obtained are as follows. First, the color tone of dyed fabrics was tinged with from yellow series to green series, in the chrominance the fabric dyed with Fe mordant was showed the highest value. Second, colorfastness to dyeing showed difference as to mordants, but colorfastness to dyeing except for sunlight colorfastness showed the good colorfastness result on the whole. Third, in the test results of antibiosis, the dyed both cotton and silk fabrics showed the very excellent antibiosis effect for bacteria but showed the insignificant effect for fungus.

  • This study was designed to obtain the basic data developing the UV ray protective garments for the plastichouse workers. Two subjects were volunteered for 1hr. wear test in plastic house, and the ensembles was composed of one of three kinds blouse (UV blocking blouse, polyester/cotton 47/53 blouse, and polyester blouse), shorts, sleeveless undershirts, pants and socks. The measurements were rectal temperature, skin temperature, microclimate inside clothing, subjective sensation, and the colour difference of UV sensor. The results were as follows: 1. Microclimate especially, temperature inside clothing of polyester blouse was the highest among the garments. And UV-proof polyester blouse showed the lower mean skin temperature and microclimate than others. Showing the highest sweat volume. 2. No significant difference on UV ray blocking function among 3 kinds of garment was shown. 3. We could conform that in spring for the plastic house wぉw s garment low thermal insulating value and wide covering area were more important factors than UV blocking function of fabric.
