Abstract

Green technology for eco-friendly dyes in textile industries has been required in recent decades. An innovation was established by producing textile dyes from natural sources. This research aims to identify fine particle powder's characteristics and analyze the color changes applied to the textile. The mechanical thermal was utilized to produce natural dyes. Three main stages were conducted to obtain dye powder: mordant, coloring, and fixation. The dye powder was examined for water content, phytochemical tests, FTIR, SEM-EDX, and color using the Android-based Color Analyzer and Color Grab applications. The results show that the water content of 7.21% meets the SNI 01-3709-1995 standard. So, the powder can be stored for a long time because it does not quickly spoil. In addition, the phytochemical test resulted in alkaloids, flavonoids, and tannins. This revealed that teak leaf powder can be a suitable textile dye. After that, SEM-EDX examination illustrated that the powder had a round, flat, elongated morphology, a sharp edge texture, and an irregular position. Meanwhile, the EDX signified that the recognized chemical elements did not damage the environment, and the powder diameter ranges from 0.5-8.5 μm. The powder size complied with the fine particle powder category. To analyze the color from the dye powder application, there were color changes during each dyeing process. During all stages, from making the powder to applying the powder to the fabric, environmentally friendly technology was utilized. Therefore, this research can promote new opportunities for innovation and development of highly competitive products towards a more environmentally friendly and sustainable textile industry.

Abstract

The Mandalika Central Lombok Special Economic Zone (SEZ) is one of the world-class national priority tourist destinations. However, until now there has been no branding of the village's superior woven products that can contribute significantly to the Mandalika SEZ. So it is important to carry out this service activity, to give birth to entrepreneurial pioneer weaving craftsmen towards "LOMBOK WEANING, LOCAL GOING GLOBAL". To achieve this goal, the craftsmen group experienced several problems (1) limited insight into the importance of developing weaving for the tourism sector towards international tourism and (2) the dyeing process was still using conventional methods which took a long time and was impractical. This problem arose due to a lack of human resources owned by the village, even though the natural resource potential it has really supports the songket weaving industrial center. Therefore, the role of academics is really needed to innovate to provide solutions to problems based on green technology. The solutions to the problems that will be offered are (1) activities to open people's insight into the importance of the tourism sector (2) dissemination of green synthesis technology using a modified steam extraction method to produce natural dye powder accompanied by students of the material characterization method course (3 credits). So that both solutions can be delivered appropriately, a systematic flow of activities needs to be carried out consisting of (a) socialization, training, (c) mentoring, and (d) monitoring and evaluation. A series of activities have been carried out, it is hoped that the craftsmen's skills will increase so that they are able to independently produce coloring powder from various existing local natural resources and be able to compete internationally. In addition, different types of leaves will produce different color pigments. Differences in dyeing processes and techniques will produce cotton threads with different qualities. In general, natural dyes always produce soft colors.

Abstract

In Lombok, the traditional process of dyeing woven fabrics primarily involves the use of synthetic dyes, which can contribute to environmental pollution. This study aimed to identify the characteristics of woven yarn and assess the effect of dye solution pH on yarn properties when using teak leaves (Tectona grandis) to produce dye powder through a mechanical thermal method. The thread coloring process comprised mordanting, coloring, and fixation stages, with the assistance of Android applications for color analysis and a Universal Tensile Machine Type RTG-1310 to assess mechanical properties. The results revealed that dyeing yarn with anthocyanin powder from teak leaves yielded a range of colors, including shades of gray, brown, and red. The highest tensile strength observed was 2,664 cN/dtex, and the solution's pH significantly influenced the dominant color, with red being prominent. Notably, optimal tensile strength (1,649 cN/dtex) was achieved at pH six. These findings highlight the potential for producing high-quality cotton threads using different dyeing processes and techniques. The study's insights contribute to both environmental protection and thread quality enhancement in the textile industry
