Autoclave development for using in natural dyes extraction and dyeing process under project plan textiles knowledge management for researching and local wisdom conservation: a case study of karen woven fabric

Abstract

This research had an aim to develop an autoclave for using in natural dyes extraction and dyeing process. The autoclave used the stainless steel as the major material what it was a noble durable material and good resistance for the chemical used in the processes. The achievement results showed by the comparison data between the conventional process and the development using autoclave in term of extraction efficiency, deep of shade (K/S), time equivalent, process time and amount of gas consumption saver. The knowledge from the research would transfer to the target group at Bann Yang Nam Klad Tai, Phetchaburi province. The results were following as 1. For the extraction process: the extraction process using 100oC for 45 min. They obtained product was the same dye quality but the autoclave process was smaller water evaporation as 26.71% whereas the conventional process was 41.99%. 2. For the dyeing process: All condition from the autoclave using make a deeper dye shade (K/S) than conventional process. The dyeing time equivalent as 15 minutes to make the depth shape via autoclave process as alike the conventional process for 45 min. 3. Saving time and gas consumption: the autoclave process could save 66.67% time process and 88.99% amount of gas consumption. 4. The Complacency for knowledge assignment: the satisfaction level in the content, time, and period was good. Furthermore, the utilization, the instructors, and the value obtained were excellent. This research accomplished the study objectives. The results were not only corresponding to energy conservation but them also reducing the chemical toxic and pollutant vapor inhalant to the worker.
