The purposes of this research were to study the properties of Tei Panan Root suitable for the development of home decor products inspired by Koh Yo woven fabric patterns to conduct the development of home decor from Tei Panan material and to study the satisfaction of experts with home decoration products from Tei Panan root material inspired by the Koh Yo woven fabric patterns. The research began by studying the properties of Tei Panan root material and developing Tei Panan root materials. The most suitable formula was selected. The properties of Tei Panan root material were evaluated to select the most suitable pattern. The researcher designed the home decoration from Tei Panan material inspired by Koh Yo woven fabric pattern dividing to 3 types of lamps including hanging lamps wall lamps and table lamps (3 forms for each type). Five experts were appointed to select the most suitable form for each type. Then home decoration products were created from Tei Panan root material inspired by Koh Yo woven fabric pattern by assigning 10 experts consisting of 5 textile experts and 5 design experts and the product satisfaction was inquired about. The results showed that in the development of properties of Tei Panan root material the most suitable formula was formula 3 and the most suitable pattern was Su Ban Ni Ka pattern (n= 3 60%). The result of the development of home decoration from Panan material inspired by Koh Yo woven fabric pattern classifying hanging lamp form 3 (n=4 80%) wall lamp form 2 (n= 3 60%)and table lamp form 3 (n=3 60%). All 10 experts were satisfied with the home decoration products from Tei Panan root material inspired by Koh Yo woven fabric pattern with highest level in all aspects of satisfaction such as materials design product usability and overall satisfaction with a mean score of 4.56.

Developing women’s clothing design from marigold-dyed linen. The objectives of the project were : 1) to study about linen dying technique with marigold with various kinds of mordant 2) to design and develop women’s clothing from marigold-dyed linen 3) to study the satisfaction of representative samples for the women’s clothing design from marigold-dyed linen. Using simple random sampling method analyzing the data with statistics percentage mean and deviation standard. The sample groups are selected from working women in Dusit District Suan Chitlada Subdistrict and students from Rajamangala University of Technology Phra Nakhon in total 100 participants. Research instruments are questionnaire and 2 women’s clothing prototypes one was dyed with natural mordant and the other chemical mordant. The results indicated that most of the samples aged from 25 and above single graduated with bachelor degree are general office workers and students and earn less than 15000 baht. The result also revealed the satisfaction for the women’s clothing design from marigold-dyed linen a design which was dyed with both natural and chemical mordant. The participants are satisfied with the modern design suited for working age and very useful at a high level with means of 4.07 and 4.05 natural and chemical mordant respectively. Considering the overall result the participant tended to be satisfied with natural mordant dyed dress more with a mean of 4.07

The purpose of this research was to study the dyeing polyamide/elastane fabric with natural indigo using exhaustion dyeing process. The effects from the concentration of the natural indigo dye thiourea dioxide and sodium hydroxide were investigated. The colour of each dyed material was investigated in term of the CIELAB (L* a* and b*) and K/S value. The color fastness to washing rubbing perspirdation light water sea water and chlorinated water of the dyed samples was determined. The bursting strengrh of dyed polyamide/elastane was evaluated. The best vatting condition was at 50 ̊C for 30 minutes. The optimal formula of dyeing polyamide/elastane fabric using natural indigo was prepared by mixing 200 g/L natural indigo paste 60 g/L thiourea dioxide 1 g/L sodium hydroxide. The fabric dyed in the solution of indigo vatting a shade of dark blue colour. The color fastness to light washing water sea water perspiration and chlorinated water were good to very good. However the rubbing fastness results showed fair level. The bursting strength of dyed fabrics is less than the undyed fabric 3.1%. The optimal ratio of discharge printing on polyamide/elastane fabric were compose of 70 % starch print paste and 30 % discharging agent (KMnO4). The pattern design produced from these combinations in the printing areas on fabrics showed an excellent standard of printing quality. The results confirmed that natural indigo dyes have potential applications in polyamide/elastane fabric dyeing and the dyed fabric can be used produce women’s intimate apparel.
