| Background Recently, interest in art movements such as eco-friendly arts and eco-design has been continuously increasing. Eco-printing is a method in which leaves and flowers, roots and seeds are pressed directly onto the fiber by heating or steaming treatment, so that the pigment of the plant is dyed on the fiber. The purpose of this study was to analyze the dyeability of eco-printing by examining the fastness to four dyed samples with onion peels and eucalyptus leaves on wool and silk fibers.
Methods Eucalyptus leaves, which are most often used for eco-printing, and onion peels, which can be easily obtained from the surroundings, were subjected to high-temperature steaming treatment at 100°C for 2 hours at 100% wool and 100% silk. After staining, it was treated with mordant. The soaking ratio was 1:50 and treated with a mordant for 15 minutes at 30°C with 5 g of aluminum, 3 g of copper salt, and 2 g of iron salt per 100 g of fiber weight. The fastness (6 tests) of eco-printing dyeing of silk and wool was tested.
Result The color fastness to sunlight was best at 4 (good) grade or higher in 2 hours steaming of silk dyed with onion peels. Washing fastness showed results of 4 (good) to 5 (excellent) in all four samples. The color fastness of silk dyed by steaming treatment with eucalyptus leaves for 2 hours was 4 grade. The color fading of water fastness showed results of 4 to 5 grade, and both the silk treated with eucalyptus leaves and wool dyed by steaming for 2 hours with onion peels was 3 (fair) to 4 grade. The color fading of the fastness to sweat also showed 4 to 5 grade. Under the acidic and alkaline condition, both the wool dyed with onion peels for 2 hours and the silk dyed with eucalyptus leaves for 2 hours showed results of 3 to 4 grade. The friction fastness was tested by dividing it ten times and dividing it into warp and weft, drying and wetting. It was found that the silk dyed with onion peels was increased for 2 hours and the wool dyed with eucalyptus leaves for 2 hours was highest. The dry cleaning fastness showed 4 to 5 grade results for both discoloration and contamination..
Conclusion As a result of eco-printing on wool and silk with onion peels and eucalyptus leaves, it was confirmed that the sun-fastness, wash-fastness, water-fastness, sweat-fastness, friction fastness and dry-cleaning fastness were all good. It is expected that eco-printing using materials of various plants, which can be easily obtained in the surroundings, can be widely used as a variety of living products, while being eco-friendly and sustainable. |
