การพัฒนากระดาษจากเส้นใยทะลายปาล์มน้ำมันเปลือกหุ้มผลปาล์มน้ำมันและเปลือกปอสา และสารเคลือบไคโตซาน
This research aimed to develop paper from oil palm empty fruit bunch (Fb) oil palm mesocarp (M) and paper mulberry (P) with chitosan coating to be used as single-use paper bag for dry food products. The optimal pulp preparation conditions for Fb M and P fibers were boiling in 25 25 and 15% NaOH solution at 170 170 and 100°C for 3 hours respectively. The optimal H2O2 concentrations for bleaching of Fb M and P pulps were 40% 40% and 0.2% respectively. The obtained pulps were used to prepare papers with the basis weight of 109 g/m2 . The papers consisted of Fb M and P pulps at ratios of 70:0:30 (FbP) 0:70:30 (MP) and 35:35:30 (FbMP). It was found that FbP paper showed superior physical and/or mechanical characteristics than those of MP and FbMP. FbP papers were then coated with chitosan solutions (0.2-0.6%) to further improve their mechanical properties and reduce their water absorption characteristics. The optimal concentration of chitosan was 0.4%. This study showed that all three types of pulps could be used to produce papers that had equal or superior mechanical- and water adsorption properties as compared to those of commercially available paper bags made from wood pulp.

The project Development of Thai hand made paper from sugar cane leaves for handicraft and package aims to study the technique of making paper from sugar cane leaves to make the prototype products made from the developed paper and then transfer the technology to the selected groups. The study included 5 steps: (1) select the target group of 60 people from sugar cane fanners community enterprise group and general public in Lopburi province (2) make the prototype products and present to public (3) prepare the tools for transferring the technology (4) transfer the developed technology and (5) evaluation and statistical analysis including frequency percentage mean and standard deviation. The general infonnation of the 60 trained people can be summarized as follows: 80.00 % is female 26.67 % is 31-40 years old and 40.00 % is sugar cane fanner. The objectives content activities and training method were evaluated to be the best suitable. The structure of the course was found to be the most suitable. More over the materials training documents and place were rated to be the most suitable to the best suitable.
