รายงานวิจัย -- มหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร, 2560Quality control of dyeing and finishing of Water Hyacinth yarns and their transformed materials for commercial was a main objective to establish the dye database of synthetic dye and natural dye. The dye database was a data for quality control in dyeing process of raw material as Water Hyacinth yarns, also it resolved the un-repeatability dyeing problem.
Reactive dye was used for synthetic dye database creation on dry Water Hyacinth yarns at 80oC for 30 minutes. Red as Hicion Red He-3B, yellow as Hicion Yellow HE-4RN, Blue as Hicion Navy Blue HER 150%, and black as Hifix Black KNN were the represent synthetic dye and Sodim sulphate 20 g/l and sodium carbo nate 20 g/l were used as auxiliaries. The other hands, the natural dye database was forming from Ebony tree, Caesalpinia sappan and Turmeric. They were dye on dry Water Hyacinth yarns at 80oC for 30 minutes and Sodim sulphate 20 g/l was the auxiliary. Whereas, Butterfly pea were dye at 80oC for 30 minutes by Sodim sulphate 20 g/l and sodium carbonate 20 g/l were the auxiliaries. The whole dye database was defined the totally in Primary, Secondary and ternary dye cycle. The transfer knowledge was distributed to the enterprise at Nakhon Prathom Provincd as “Chumchonjaksanpaktobchawha Bann klongnokkratum”. The topics were “How to establish the synthetic and natural dye database”, “Water repel lent finishing”, and “developed and transformed the Water Hyacinth to products”. The target group was very satisfied in this topic as 4.39. In the result, the proportion between economic and social factor by the income increasing in 1 year was 5.04. So, the research project was achievement.Rajamangala University of Technology Phra Nakho
