This research studies dyeing with Thai herbs for UV protection properties in textile products applications and aimed to: study procedures and techniques for this; investigate the use of herbal plant for UV protection; study UV protection properties in fabrics dyed with Thai herbs that can protect against UV rays. The process involved dyeing from natural surplus materials (militia kityana leaves lemongrass leaves and areca palm seeds) extracting the dyes for use in silk dyeing with a mordant to increase the affinity of the dye and fiber then rating the percentage of UV light blocked. Finally the fabric was used to design clothes as a prototype for five Muslim outfits. The research team chose dyed silk fabric with the percentage of UV light blocked are 95.67 – 96.24 which is in good to excellent protection level. Five outfits were designed for this study: 1) Silk dyeing with dyes extracted from the lemongrass leaves – using the first method of fabric dyeing with clear muddy water 1% as mordant 2) Silk dyeing with dyes extracted from lemongrass leaves – using the fourth method of fabric dyeing with the fabric fermented for 30 minutes in mud before dyeing 3) Silk dyed with dyes extracted from areca palm seeds – using the first method of fabric dyeing with 3% tamarind water as mordant 4) Silk dyed with dyes extracted from areca palm seeds – using the fourth method of fabric dyeing with the fabric fermented for 30 minutes in mud before dyeing and 5) Silk dyed with natural dyes extracted from militia kityana leaves – using the first method of fabric dyeing with 1% tamarind water as mordant.

Water Hyacinth Yarns and Their Transformed Materials Dyeing Machine for Developing Small and Medium-Sized Enterprises was a research project what an aim for producing a prototype dyeing machine. The machine was used at the small enterprise in Nakhon Prathom province. The dyeing machine was contributed by stainless steel. The outer dimension was 100 centimeters in height 130 centimeters in length and 90 centi-meters in width. The inner structure contains with perforate stainless steel drum. It had diameter as 80 centimeters with 90 centimeters length. The container capacity was 27 liters for the raw material as 10 kg of the dry Water Hyacinth Yarns or 5 kg of the dry Water Hyacinth roots. The machine was running test for reactive dyeing process at 80oC for 30 minutes. The machine was achieved for reduce time operation as 5 times and gas consumption as 2.38 times. The break-even point was 1.09 year and B/C as 2.22. Moreover it can solve the fuzzy yarns problem and the volatile smoke during the tradition dyeing. The knowledge was transferred to the stakeholders at the target area as “Chumchonjaksanpaktobchawha Bann klongnokkratum” enterprise in Nakhon Pra thom province. They were satisfied in this benefit in good to very good level.

The purposes of this special project were 1) to study dying process of canvas fabric from dried teak leaves 2) to design women’s bags with dyed canvas fabric from dried Teak leaves and 3) to study satisfaction of respondents towards women’s bags with dyed canvas fabric from dried Teak leaves. The procedures has 4 stages follows as; dyed canvas fabric from dried Teak leaves designed women’s bags made prototype product and survey satisfaction of respondents towards bags. Data collected from sample of 120 women by questionnaire. Analyses of the data were performed with frequencies percentage and mean. The results showed that most of the respondents were age below 25 years (92.50%) status of single (93.33%) bachelor degree education level (80.00%) monthly income 5000 baht or less (57.50%) place of questionnaire response at Ruenpanya Building RMUTP (83.33%). The respondents satisfied to women’s bags overall was very satisfied level (4.46). Mean of each bag was extremely satisfied level and sorted from the high mean as follows; bag style 4(4.53) bag style 3 and bag style 5 (4.51 as equal). More suggestion to product prototype was more decoration and had a small bag inside for keep coins.

This special project aimed to determine the appropriate procedure for extending carved dye radish (CDR) and study the type for coating CDR. From the results radish was carved become to rose shape and immersed in peroxyacetic acid 0.08% and calcium choride 1.5% after that was immersed in food dye solution such as blue 0.01% 0.05% and pink 0.01% 0.05%. Then CDR was coated in three types of coating namely xanthangum gelatin and agar. From the result xanthangum has weight loss yield% firmness and color value more than galatin and agar. CDR with blue 0.01% has weight loss yield% 3.24 firmness 3.12 N color value L* 55.09±0.04 a* -20.52±0.07 b* -15.93±0.57 blue 0.05% has weight loss yield% 3.24 firmness 26.01 N color value L* 45.54±0.03 a* -25.70±0.20 b* -26.85±-0.29 pink 0.01% has weight loss yield% 3.09 firmness 23.99 N color value L* 55.03±0.11 a* 29.42±0.05 b* -0.39±0.24 and pink 0.05% has weight loss yield% 3.27 firmness 24.41 N color value L* 45.08±0.07 a* 39.75±0.27 b* 0.30±0.16. The carved radish with blue and pink storage in plastic box stored in aluminum foil at 3-4 ๐C were during 5 days. Microorganism indicated that there were no more than 1×106 colonies per 1 g of sample.

The purposes of this research were1) to study the process of dried banana leaves’ dyeing with natural dye and scientific dye and 2) to study the results of dried banana leaves’ dyeing with natural dye and scientific dye. Dried banana leaves were bleached by using three formulas as follows: 1. Mix Haiter with water in the ratio 1:1 2. Mix Haiter with water in the ratio 2:1 and 3. Mix Haiter with water in the ratio 3:1. Soak 300 grams of the dried banana leaves for 5 days and record the results. The result of this experiment indicated that the third formula wassuitable to whiten and toughen dried banana leaves. After choosing the suitable formula for bleaching
