  • A new dyeing M/C, called Green-flow was developed in this study. A new M/C was applied to mixed air flow method combined aerodynamic technology to fabric speed power. The polyester fabric was dyed of beige color with a new M/C and Luft-roto dyeing M/C made by Thies Company(German) with the same dyeing condition (liquor ratio=1 : 3.5, Fabric speed = 450yds/min.) for comparision. The results showed that the color fastness to dye and drapability of the fabrics dyed with both M/C were almost the same and the levelness and T.H.V of the fabrics dyed with Greenflow were better than those dyed with Luft-roto M/C. In addition, it is found that the fabric speed of 502yds/min was a suitable for both M/C.

  • Recently, as the demand for masks increases, the use of filter-replaceable cotton masks is increasing. A filter-replaceable cotton mask is one of the ways to solve the environmental problems of a disposable nonwoven mask because only the filter can be replaced after washing. Cotton fiber products are known to be environmentally friendly, but cotton products dyed with general synthetic dyes are not safe for humans. In this study, to prepare of cotton mask applied with natural dyeing, the optimal dyeing conditions are set when dyeing with gallnut extract. A polychromatic natural dye that changes color by mordant, and the functionalities of gallnut dyeing fabrics are evaluated. The experimental method is dyed the gallnut by temperature and time by concentration to set the optimal conditions. The color fastness rating grade of aluminium potassium sulfate dodecahydrate, copper(ll) sulfate pentahydrate, and iron(ll) chloride tetrahydrate were evaluated after the pre/post mordanting.

  • African marigold is a common plant easily available in many flower beds. It has been reported as a practical and prospective resource of dyes since the dyes can be extracted from their bodies as well as petals. In this research, cotton and ramie fabrics which are made from natural cellulose were dyed using the extract of the African Marigold which is a variety of marigold. Dyeing tests were carried out under different pH of the dye solution and mordants. Dyeability was evaluated by examining and measuring surface color, K/S value, and the changes in the maximum absorption wavelength. The probability of improving dyeability was investigated by pre-mordanting with pre-treated chitosan. For the dyeing with marigold extract, the color tone did not differ by pre-mordanting and non-mordanting. Reaction with post-mordanting was excellent, which was colored in various yellow series. The best dyeability was achieved in dye solution of pH 6.5-7.0 which is not conditioned. The largest K/S value and color difference were obtained in tin mordanting. The dye uptake was greatly increased in chitosan pre-treated mordanting compared with the post-mordanting without chitosan pre-treatment. Due to its high heat resistance, African Marigold extract is easy for dye extraction and dyeing, and its dyeability is excellent for natural cellulose fibers. Also, colorfastness was proved to be practically usable.

  • For the efficiency in extracting gromwell colorant, methanol, ethanol and aceton were used as solvents. Also, to compare the results when dyed in various conditions and on various fabrics, the ratio of water-dye mixture, pH, temperature, and varieties of fabrics -wool, silk, cotton, nylon, ramie- were selected. L, a, b, ΔE, munsell and K/S value of each sample was measured and compared for the practical use. Water-dye mixture of 5:5 ratio showed the optimum dyeability. Not to mention wool and silk, but also cotton showed a satisfying dying result at the acidity of pH4. As the temperature increased, the dyeability of all three fabrics improved greatly. Especially, wool showed the highest improvement in terms of dyeability as the temperature increased. K/S values for wool and nylon showed superior results to the others in the gromwell colorant. The resulting color turned out somewhat different depending on the solvents used and the sort of fabric that was tested on. When the gromwell colorant extracted with methanol or ethanol was applied, the color of fabrics came out as purple or purpleblue. When the colorant extracted with acetone was used, the color of fabrics came out to be redpurple. The colorfastness to light showed low glades regardless to whichever solvents were used. The grades of colorfastness to laundering were recorded low numerical values, and its record became even lower when the gromwell colorant extracted with aceton was applied. The staining grade of the colorfastness to laundering showed a good grade in the range of 4 to 5. All the dyed fabrics showed a excellent drycleaning fastness.

  • The natural dyeing industry has been faced with increasing demands of constant needs for environmentally and body friendly clothing products among modern consumers. Natural dyeing has attracted attention as a next-generation technology in green textiles. Dyestuffs need to be diversified for technological development activation in order to meet the increasing demands for natural dyeing. This study extracted dyeing solutions from the leaves of the Rose of Sharon (the national flower of South Korea) and investigated its dyeing properties for the development of various natural dyestuffs. This study investigates the dyeability of silk fabrics with Rose of Sharon leaves extract. Optimal conditions for dyeing of silk fabrics with the extract of Rose of Sharon were $40^{\circ}C/80min$ and $90^{\circ}C/60min$ with 100% concentration. Looking at the results, it showed the best K/S value at pH3, Sn pre-mordanting and Fe post-mordanting. Color fastness to washing, dry cleaning, rubbing and perspiration was good at grade 4-5 or 4. However, light fastness was observed in grade 2. In aspect of functional property, it showed an excellent result of 90% deodorization rate. In addition, its proven functionalities (deodorant properties) will help to produce high value added environment-friendly products. Those findings demonstrate the possibilities of the Rose of Sharon as an environment-friendly dye.
