The purposes of research are 1) to study the best rice straw pulp process; 2) to study the balance portion between the rice straw and the natural indigo for paper production; and 3) To study the UV protection property of 3 types of rice straw papers which are pure rice straw paper, natural indigo mixed with rice straw paper, and the twist rice straw paper covered with natural indigo.

     The study of three sizes of rice straw for 2, 4, and 6 centimeter long in Effective Microgranisms for 5, 10, and 15 days showed that the best rice straw pulp came from the rice straw in 4 centimetres long with 5 days of fermentation. It created the delicated rice straw pulp for the suitable paper thickness. Then, the balance portion from mixed the rice straw pulp with the natural indigo in 3 levels: 1:1, 1:2, and 1:3 (weight-to-weight) belonged to 1:3 as it revealed the strongest navy shade for a paper production. Lastly, the UV protection property of 3 types of rice straw papers showed that every types were able to absorb UV rays and equally contained UV protection property (p>0.05). Therefore, the recommended rice straw paper would be the twist rice straw paper covered with natural indigo for UV protection hat according to its durability.
