  • Three fabrics, 100% silk, nylon and cotton each, were dyed with a lichen dye solution prepared by a fermentation method under conditions of varying dyebath pH and temperature. To verify the effect of chitosan on fabric dyeing, the 100% cotton fabric was treated with a chitosan solution before dyeing. The K/S, CIE $L^*$, $a^*$, $b^*$, ${\Delta}E$ and Munsell values of the dyed samples were measured. Colorfastness of each sample was also investigated. The maximum K/S value was measured at 520nm wavelength for the dyed silk fabric and at 480nm for the dyed cotton and nylon. The K/S values for the dyed silk fabric were much greater than those of the other fabrics. The dyed silk fabric showed a red tone on the Munsell color system, and the dyed nylon and cotton fabrics a yellowish red tone. Dye affinity to fabrics was better in a neutral or acidic dyebath. As dyeing temperature increased, K/S values increased for the dyed nylon and cotton fabrics but not for the silk. Dyeability of cotton fabrics could improve by Chitosan treatment. As for most natural dyes, colorfastness of all dyed samples was poor. The silk fabric showed an excellent dry cleaning fastness of Grade 5.

  • 현재 다운방한 용도에 사용되는 직물 트랜드는 경량화 및 박지화 추세에 있으며, 국내외 유명 브랜드에서 사용되는 스포츠웨어 직물소재의 대부분이 이러한 제품으로 판매가 이루어지고 있다. 현재, 국내외 다운방한용에 사용되는 원단은 겉감이외에 다운 세기방지용 안감직물을 사용하여 다운이 빠져나오지 않도록 하고 있음. 그러나, 최근 겉감으로 사용하여 다운이 세지 않고 매우 가벼우면서 Packable 원단개발이 요구되고 있을 뿐만 아니라, 다운방한직물에 요구되는 성능에 만족하거나 성능이 향상된 고기능 원단개발이 요구되고 있다. 이러한 다운방한용 직물은 다운의 내구성 및 지속성 측면에서 매우 많은 기능이 요구되고 있으며 현재 국내에서 사용하고 있는 다운방한용 직물은 다운커버직물을 사용하거나 코팅에 의해 다운세기 방지기능을 강제로 발현시키고 있다. 그러나 그 직물은 경량화 되어가고 있기 때문에 다운커버 직물을 사용하지 않으면서부터 다운이 세는 문제점, 그리고 공기투과 및 투습이 제대로 되지 못하는 기능성의 문제점, 경량화와 더불어 인열강력이 약하여 잘 찢어지는 문제점, 인열강력의 물리적 특성을 높이고자 코팅을 하게되면 기능성 및 감성이 더욱 나빠지는 문제점이 나타나게 되어 다운 방한용 직물은 큰 문제점이 되고 있다. 이에 겉감만으로도 다운방한용도에 적합한 고감성 및 기능성을 가진 경량직물 개발을 위해 고밀도 제직 및 설계 기술, 최종 염색가공 및 후가공 공정까지의 공정내(內) 간(間)연계기술을 연구하였다.

  • This study examined non-destructive UV-Vis spectrophotometry as well as 3-D fluorescence spectrophotometry of textile that made use of red dye such as Sappan wood, madder, Safflower, Gromwell. The authors produced two textile specimen that were dyed by not only two kinds of textile (cotton and silk) but also three kinds of mordanting (no-mordanting, alumen and iron), and they investigated effects of each dye material upon investigation results. At analysis with UV-Vis spectrophotometry of dyed textile specimen, dyeing made by sappan wood, madder and gromwell had significant difference depending upon mardant regardless of kinds of textile, and safflower had no significant difference depending upon textile and mordant. At analysis with 3D-fluorescence spectrophotometry, specimen dyed with sappan wood had difference with mordants, and with madder, there were difference with textiles, and safflower had inherent fluorescence spectrum regardless of textiles and mordants, while gromwell had no fluorescence spectrum.

  • This study concerns UV-Vis spectrophotometry and 3D-fluorescence spectrophotometry analysis of textile parts of blue and green tones dyed with indigo of blue tone and turmeric, gardenia, goldthread and amur cork tree of yellow tone. In order to verify whether the kinds of textiles affected analysis result of each dye, silk and cotton textile samples were produced. According to the analysis of the degree of reflection of UV-Vis spectrophotometry, unique reflection spectrum of indigo appeared regardless of the kinds of textiles when they were dyed with indigo. As for textiles of green tone, the 3D-fluorescence spectroscopic analysis result showed that unique spectrums of yellow dyes, turmeric, goldthread and amur cork tree appeared regardless of the kinds of textiles but the fluorescence spectrums of gardenia and indigo did not appear.

  • 본 연구는 노멕스 직물과 일반 방염직물의 쾌적성에 영향을 주는 중요한 인자를 찾기 위하여 직물의 열적 성질과 역학 성질에 관하여 연구한 것이다. 사용된 직물은 재해를 일으킬 수 있는 환경에서 방호용 의복으로 사용되는 노멕스 직물이 주를 이루며, 비교를 위하여 방염직물과 쾌적성이 좋은 일반직물을 포함시켰다. 직물의 물리적 성질과 열 특성을 측정하였으며, 역학 성질을 측정하여 노멕스 직물과 다른 직물을 서로 비교 분석하였다. 노멕스 직물은 파이버 자체가 뻣뻣하기 때문에 쾌적성을 향상시키기 위해서는 소프트감을 높이는 것이 중요한 요소라는 것을 확인할 수 있었다. 같은 노멕스 직물이라도 쾌적성 면에서 서로 차이를 보여주므로 직물의 구조적 성질이 직물을 구성하고 있는 파이버 성질보다 쾌적성에 더 영향을 미치는 것을 알 수 있었다.

  • This study dyed rayon fabric using loess as a natural colorant. To obtain the optimal dyeing conditions, various dyeing conditions were examined (temperature, pH, time, and concentration). The color fastness was evaluated using standard washing and rubbing fastness tests. The results were as follows: The loess powder particle size ranged from 0.4 to $1.7{\mu}m$ with a distribution range of 1.1 to $1.4{\mu}m$, representing a fine and uniform manufactured loess powder. The loess component analysis showed a large amount of silicon dioxide and aluminum oxide. TheFT-IR spectra showed that the ammonium group in the rayon fabric produced N-H banding at $1,540cm^{-1}$. The highest K/S value for the rayon fabric was obtained when the pH was 8.0, and this value increased rapidly with a longer dyeing time and when increasing the loess concentration to 30% (w/v). Pre-treatment with a soybean solution produced the highest K/S value for the rayon fabric with a loess concentration of 30% (w/v). The SEM analysis showed a higher amount of loess adhered to the rayon fabric surface when increasing the loess concentration. However, pre-treatment with a cationic agent and soybean solution resulted in a much higher attachment of loess to the fabric surface. Thus, the experimental results showed that using a cationized fabric and pre-treatment with a soybean solution are more effective when dyeing rayon fabric with loess than when using only loess.

  • This is the analysis of material dyed with Korean yellow dyes such as tumeric, amur cork tree, goldthread, gardenia, and the flowers of sophora japonica using nondestructive ultraviolet-visible and fluorescence spectrophotometry. In order to find out whether type of fabric or mordant influences analysis results, test fabrics were made using two types of fabric(silk and cotton) and dyed using three different mordants(no mordant, alum, iron). After analysis with UV-Vis reflectance spectrum on the dyed fabric, when the fabric was dyed with tumeric, amur cork tree and goldthread, the results were similar with no mordant and alum mordant, whereas there was a difference with an iron mordant. Also when the fabric was dyed using gardenia, different fabrics brought different results but there was no difference in results with mordants. On the other hand, when the fabric was dyed using the flowers of sophora japonica, there was no difference with fabrics but with mordants. After analysis with 3D-fluorescence spectrum, fabrics dyed with tumeric, amur cork tree and goldthread showed their own fluorescent spectrum with no regard to fabric and mordant; but with gardenia, there were differences with different fabrics whereas with the flowers of sophora japonica, there were differences with mordants.
