Characteristics Development of Rice Straw Paper as a Raw Material for Community enterprise Products, Kra-chang Sub District, Samkhok District, Pathum Thani Province

Abstract

The rice straw paper sheets that are produced using traditional methods with weak properties for creating and designing various products. Adding binders such as rice flour, glutinous rice flour, and tapioca starch in the ratio 6% per fresh weigh will have positive effect on the rice straw paper in terms of color values, tensile strength and tear strength values, puncture pressure, and bond strength the results of the study were as follows; the color values measured by the L* a* and b* systems found that the rice straw paper using glutinous rice starch binder the L* value was 84.83±0.02, the a* color value was -0.11±0.02, indicating different greener characteristic than other paper. The yellow color, which is the basic color characteristic of rice straw, paper using binder that is tapioca starch has a color b* value of 18.69±0.01 and also gives a brightness value of 48.9%, which gives the highest value. The strength properties of the paper show that paper made from randomly shredded straw pulp has higher characteristics than other rice straw paper. The tensile strength and tear strength values were 21.27 Nm/g and 4.7 mN.m²/g, but rice straw paper mixed with rice flour showed higher values for resistance to puncture pressure and bond strength within the maximum is 1.5 kPa.m²/g and 266.29 J/m². The satisfaction results for rice straw paper that received the highest overall satisfaction score were paper made from randomly shredded straw pulp than other rice straw paper, which received high overall liking score got score of 4.16, the rice straw paper with addition of rice flour which is the binder received an overall accepted score of 3.33. Such characteristics that paper has whiteness and brightness can be used as a material for drawing and the strength of paper is a guideline for community product development.
