Quality 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”.

Sweet tamarind is a unique and economic plant of Phetchaboon province and it has already been geographical indication (GI) registered. One of its main problems is fungal degeneration which cannot be physically visible. This causes the consumer’s uncertainty on its quality especially sweet tamarind from small communities. This led to the study on the use of household heat to reduce fungal degeneration by steaming at 100oC for 50 60 70 and 80 minutes and drying in the hot air oven at 70oC for 3 hours. It was found that increasing the heat resulted in darkening the sweet tamarind color and heightening up its content moisture (p<0.05) statistical significance. Drying temperature at 60 70 and 80oC revealed the higher the heat the shorter the drying time and the sweet tamarind content was darker. In addition drying significantly decreased the moisture and preference score of sweet tamarind (p<0.05). The storage of sweet tamarind in mesh bag at ambient temperature revealed that the increase of the storage time resulted in a significant increase in the moisture of the sweet tamarind shell (p<0.05) and could preserve the tamarind for at least 12 weeks without the deterioration from the fungus.
