การใช้ประโยชน์จากน้ำแช่เมล็ดถั่วดำแห้งในกระบวนการย้อมสีสิ่งทอ
The purpose of this research was to investigate the use of soaked black bean water and to add value to it otherwise it is considered as colored waste water. The soaked black bean water was analyzed for phytochemicals and dyeing process was carried out silk cotton and polyester fibers. Dried black beans were soaked in water ratio 1:1 for at least 12 hours. The dyeing process involved soaking the fiber in soaked black bean water at 100o for 30 min. to determine the type of fiber staining and color fastness. Results showed presence of Anthocyanin Anthraquinonoid Terpenoid Saponin Tannin and Flavonoids in soaked black bean water. It was found that dye could be absorbed by silk fabric in an acidic condition. The shade appeared red-brown at L*44.17 a*16.88 and b*20.13 color strength was 6.19 and ultraviolet protection was blocked more than 97.5 percentages as UPF 50+. Moreover the color fastness grading in crocking property was very good to excellent (CF 4-5) good washing fastness (WF4) and moderate fastness in the presence of light (LF 4). In conclusion soaked black bean water can be used for dyeing for silk fabric and enhance UV protection.
การควบคุมคุณภาพการย้อมสีและตกแต่งสำเร็จเส้นด้ายผักตบชวาและวัสดุประกอบเพื่อการแปรรูปผลิตภัณฑ์เชิงพาณิชย์
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”. 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.

This research had an aim for studying the printing process of LACCIFER LACCA KERR. (LAC) on cotton and polyester fabric. The Lac dye was extracted by using Sodium hypochlorite solution Sodium hydroxide Hydrogen peroxide and diethyl ether then Acetic acid was used for dye sedimentation. Thenthe printing condition and color fastness to washing crocking and light were examined. The efficiency of solution for extraction process were found Diethyl ether > Sodium hypochlorite solution > Sodium hydroxide > Hydrogen peroxide respectively. The hot air was suitable fixation process for cotton and polyester printing. The cotton fixation was 150oC for 5 minutes it is 11.87 in color strength. And the polyester fabric was fixed at 220oC for 3 minutes the 8.27 color strength was shown. The both of cotton and polyester were printed with Lac dye had the good color fastness to crocking and light and moderate in washing fastness. This study can apply the Lac dye on cotton and polyester fabric by a printing technique without mordanting. Then it can reduce some chemicals in the textile printing industry. This process can applied and transfer for small enterprise for Lac value added appication.

This research had a main purpose for studying the utilization of water hyacinth as the key component of paper production mixed with the agricultural waste as pineapple leaves and leaf sheath of banana tree. The paper pulps were prepared from 5 g/l NaOH at 90-95oC for 3 hours then bleaching with 5 g/l Hydrogen peroxide at 90-95oC for 30 minutes. The whole pulps were detached improvement with 5g/l Acramine 3187 before paper establishment production. Finally the strength of obtaining papers was consideration and competition to any craft paper type. As the results the appropriate ratio of paper was 70% water hyacinth (stem) 10% pineapple leaves and 20% leaf sheath of banana tree. It had 31.19 kN/m2 for bursting strength tearing strength as 309.17 mN and 0.49 mm thickness. The basis weight was 183±5 g/m2. The achieved paper was equivalent as KI craft paper. It was presented for packaging boxes and other procedures.
การพัฒนาการเตรียมสีผงจากสีย้อมธรรมชาติ
The objective of this research is to preparation of dye powder from natural dyes. The conditions of preparation of dye powder and properties of natural dye powder were studied. The natural dyes were used in this research containing of Lac Ebony heart wood Sappan heart wood Turmeric and dried Butterfly pea. The natural dyes powder were prepared by three methods; oven drying salt adsorption and salting out. The natural dyes powder were dyed on silk fabric and then characterized by colour strength (K/S) washing fastness and light fastness. The results showed that the dye powder from dried Butterfly pea could not be prepared by dye powder preparation used in this research because of the dye power was not stable. The dyes powder from Lac Ebony heart wood Sappan heart wood and Turmeric were prepared by all three methods. The oven drying and salting out methods showed higher K/S than salt adsorption method. And the K/S of dyes powder from oven drying and salting out methods were not significant. In the oven drying method showed good K/S on silk fabric dyed from the turmeric dye powder. And salting out method showed good K/S on silk fabrics dyed from Lac Ebony heart wood and Sappan heart wood dyes powder. The different dye powder preparation methods did not effect on the colour appearance. The washing fastness of dyed silk fabric from different preparation methods were not significant. The dye powder of Lac Ebony heart wood Sappan heart wood showed good light fastness and the Turmeric dye powder showed poor light fastness on silk fabric.
