Morfologi dan Sifat Mekanis Kain Rami (Boehmeria nivea (L.) Gaud.) Sebelum dan Sesudah Ecoprinting

Abstract

Each type of fabric has different properties and characteristics, so that washing, drying in UV sunlight and ironing can cause changes in the color of the fabric. For this reason, it is necessary to conduct fastness tests through washing and drying tests, weather resistance through ironing and ultraviolet on sustainable fashion. The research method uses a completely randomized design with a treatment factor of fabric type consisting of A1 = Bandung 1, A2 = Bandung 2, A3 = Bandung 3, A4 = Korea and A5 = Wonosobo. The second factor is the type of Mordan consisting of M1 = Tanpa mordan, M2 = Mordan Al, M3 = Mordan Fe, Al, M4 = Mordan Ca, Al and M5 = Mordan Al, Fe, Ca. Data analysis was carried out using the analysis of variance and Duncan's test. The results showed that different types of fabric can give different results in terms of fastness and color intensity. Different types of mordants can give different results in terms of fastness and color intensity. The interaction of fabric type and mordant type has a very significant effect on color fastness and intensity. Bandung 4 fabric with Mordant 1 has the highest L* value with treatment after washing and ironing. Wonosobo fabric with Mordant 4 has the highest a* value in the treatment before washing, followed by UV sunlight and after washing. Wonosobo fabric with Mordant 4 has the highest a* value in the treatment before washing, followed by UV sunlight and after washing. The findings of this research provide both scientific and practical insights for the development of environmentally friendly textile products using natural dyeing techniques (ecoprint).
