NATURAL-COLOR CREATION FOR DYEING CALATHEA STRIPS FORCLEAN TECHNOLOGY APPROACH

Abstract

This study examines the properties of Calathea in basketwork and the process of dyeing Calathea strips with natural materials.It adapts clean technology principles to reduce energy consumption and waste in the production process.Further, it evaluates the community’s product designs to test the market by consumer groups and area, which is a group of farmer housewives living in Thung Fon District, Udon Thani Province,thatuse Calathea for basketwork. The data were collected through surveys observation, test materials, publicized design works in exhibitions, and designs evaluated by 1,000 selected tourists.The results indicate that strips from Calathea barks are shiny. When woven as a food container, they can be used and cleaned with no weevils, termites, and molds
infestations. Natural color from wood vinegar can be dyed faster, whichreducesthe duration by up to 60 hours. Clean technology principles in the production process dependon a management system that the community can practice by complying with three principles,which are saving, waste reduction, and reuse;these principlesfocus on pollution reduction at source. Wicker is used for products in the traditional way of the community, such as for woven bags and key chains, emphasizing simplicity and minimalism. Theevaluation of product designof1,000 tourists revealed that they were satisfied with the design work for whichthe overall satisfaction level was the highest (average = 4.69), whereasthe satisfactiontoward the beauty of natural-colored wicker products or wood vinegarhad the highest opinion level (mean = 4.72).
