The Guidelines of Product Design from the Vetivers Grass Fiber Innovation (Case Study of the Handicraft Product Group, Phayao Province)

This research aims to study the process and the physical property of the vitiate grass fiber by spinning vetiver grass with other natural fibers such as cotton, SamiaRicini, silk and plastic fiber such as plastic rope, wire rope and straw rope. The exploration was conducted by Ban KoSoa women group cooperative settlement, Ban Kae Mai handicraft product group and Ban Don Chai handicraft product group in Pusang District, Phayao Province. The physical properties examination, namely- ASTMD 1059-2001 Standard Test Method for Fiber Size, ASTM D 2256- 2002 Standard Test Method for Fiber Toughness with Hardness and Flexibility fiber Equipment, the results of examination would be brought to determinate for the handicraft product development design. The results from this exploration revealed that the fiber size was 0.73-0.15Ne, the tenacity (toughness) as maximum tensile strength was 4.75-9.97 kgf and the elongation at break was 7.73-11.48 percentages. The vetiver grass fiber mixed with straw rope had the tenacity as maximum tensile strength with differently at the statistically significant level of .05, the tenacity as maximum tensile strength average at 9.9 kgf, the vetiver grass fiber mixed with cotton fiber had the tenacity as maximum tensile strength with differently at the statistically significant level of .05, the tenacity as maximum tensile strength average at 6.60 kgf. The vetiver grass fiber mixed with wire rope had the highest elongation at break with differently at the statistically significant level of .05 by with the elongation break was 11.48 percentage. The vetiver grass fiber mixed with SamiaRicini fiber had the elongation break point with differently at the statistically significant level at .05, the elongation at break was 11.6 percentage. According to the handicraft product development guideline from the physical property of the vetiver grass fiber on the basis of this finding, the strength fiber as the vetiver grass fiber mixed with straw rope fiber or cotton fiber could be used for supporting weight product requirement, the elasticity fiber as the vetiver grass fiber mixed with straw rope fiber or SamiaRicini could be used for product which soft and flexibility requirement, the utility from using fiber color that spinning for beauty could be used the vetiver grass fiber that spinning and mixed with other fiber.Â
