สมบัติการดูดซับน้ำมันทอดอาหารของนอนวูฟเวนจากเส้นใยเซลลูโลสฟางข้าว
The objectives of this research were to study cellulose fiber extraction from rice straw with sodium hydroxide in various conditions (with 5 1 0 and 1 0 % of sodium hydroxide at room temperature 60ºC and 90 ºC for 0.5 1 2 and 3 hours) and to study rice straw nonwovens preparation by the wet-laid process. Oil wicking ability oil absorption ability air permeability morphology and physical properties of prepared nonwovens were investigated. It was found that the optimal condition for cellulose fiber extraction from rice straw was 5% of sodium hydroxide at 90 ºC for 2 hours. At this condition the cellulose fiber yield of 2 2% and the fiber length of 1 . 9 6 cm were obtained. The oil wicking ability and oil absorption ability of rice straw nonwovens increased when weight per unit area increased. Therefore oil absorbed into gaps between fibers of the nonwovens by capillary effect. Moreover the nonwovens could wick and absorb virgin palm oil better than fried palm oil because virgin palm oil has a lower viscosity than fried palm oil. The viscosity increased from derived lipid and other substances which dissolve and disperse increasing after frying food. The results indicated that the rice straw nonwovens had oil absorption ability.

This research is Yarn Development from Rice straw to commercial. It aims to study the process of seperating fibers from rice straw. To study the physical properties of fibers from rice straw and to study the process of manufacturing yarn from rice straw fibers. The research material is rice straw fibers after that data was analyzed byphysical textile testing laboratory. The result of the first year’s research was the rice straw yarn has been developed as woven and develop into commercial products to promote. The process of separating fibers from rice straw which dried the sun for a few days. Selecting the rice straw fiber length at least 30 cm. to subtract the joints of the lower end of the stem by hand. peel off the rice straw fiber and place flat on a horizontal line. Then Rice straw fiber were tested in the physical laboratory was found that it is cellulose fibers tensile strength (Newton) at 28.18 elongation (percent) is at 2.01. The amounts of metals has plenty of CADMIUM at 0.1 mg/kg CHROMIUM (TOTAL) / (VI) at 0.5 mg/kg COPPER at 0.5 mg/kg and LEAD at 0.1 mg/kg which was not found to be risk for using. The fiber cross-section of rice straw fiber were found to be oval the middle is clearly. The fiber length is smooth and transparent when viewed from the side to see the clarity of the fiber. Rice straw fiber was weave in plain structure. Warp yarn uses a special brown cream and brown flat yarns. We use rice straw fiber with the same type of yarn. There are 2 warp yarn and using natural color without blench. Rice straw fabric was dyeing with dried hibiscus flowers (Kaa-Jeab herb) and mordant as ashes. The result is red light because of rice straw fiber surface is smooth and lustrous.
