This research was concerned with the fiber separation and non-woven preparation form sugar canes leaves. The separation process was carried out by chemical pulping method at 100 degree Celsius. In order to study the suitable condition for separation process the concentration of sodium hydroxide ranging from 0 -20 grams per liter and boiling time 15 30 45 60 75 90 105 and 120 minutes were performed. Web formation process was performed by wet laid method and polyvinyl alcohol was selected as binder in web bonding process. in order to study the suitable amount of binder in bonding process concentration of polyvinyl alcohol ranging from 1 2 4 6 8 and 10 % w/v coated on web surface and cured at 120 degree Celsius. Bursting strength as well as physical properties evaluation of non-woven fabrics was performed. For antimicrobial finishing process was performed by spray method and pad method. The finishing result was evaluated by MTCC test method 147-1998 (Qualitative) and 100 -1999 (Quantitative) The result was found that appropriate condition for fiber separation was recommended as follows: the amount of sodium hydroxide of 10 grams per liter and boiling time 60 minutes. The suitable amount of polyvinyl alcohol for web bonding process was 2 % w/v. Bursting strength of non-woven fabric was 53 kN/m 3 and padding method was a suitable method for antimicrobial finishing (antimicrobial area 0.3 millimeters )

The objective of this paper was to study and development of rice straw paper and development of rice straw paper products-making. Part I. Rice straw paper-making. The bleached and unbleached with 2% HP2(aqJform rice straw fiber was boiled with 2% and 4% NaOH(aq) The 4 treatment was take out container and spread in to thin piece of paper. The 4 treatment were conducted to test physical properties and strength properties on rice straw paper. Part II Rice straw paper products-making. The populations in this research were 16 students and 16 teachers on RIT. Chotiwet Campus to making and evaluate the rice straw paper products. The instrument used in this research were questionnaires about the admission on specifics properties of rice straw paper products and satisfaction to rice straw paper products. The data were analyzed by SPSS program. The statistic used that mean standard deviation one way ANOVA and two way ANOVA. Differences between various groups were tested by Scheffs method.

The objective of this research project is to develop an effectively applicable prevention of heat for concrete masonry unit wall. By using kaolin mixture coir rice straw and husk as a major ingredient in concrete to replacing usual stone dust the hollow non-load-bearing concrete masonry units obtained had the size of 70 X 190 X 390 mm. The test results showed that the reliably ideal ratio of these mixture materials had to be from the combination of kaolin coir rice straw and husk by replacing them at 5%: 5%: 15% and 50/0. The block obtained also had other certain qualifications such as Weight at 6.08 kg. water absorption at 7.96% and compressive strength at 65.4 ksc. Moreover these combined materials harbored heat capacity less than the standard concrete masonry units with the weight not more than 29%.

In this paper silica-based geopolymer matrix reinforced composites containing approximately 35 50 or 55 wt.% of carbon (HTS 5631 1600tex 24K TohoTenax) advanced basalt (BCF13-2520tex KV12 Int Basaltex) or electrical grade glass (E-glass: E2400P192 Saint-Gobain Vetrotex) roving fibers respectively were synthesized and fabricated at ambient conditions. The flexural properties of the resulting composites which are high toughness: the shear stress plays here a greater role in compared with other ceramic matrix composites were determined on a universal testing machine under three-point bending mode in accordance with novel size-independent method which based on testing specimens at different scale of sample height (H) to span length (L) ratios; The basic principles of the new size-independent approach are presented as well. Microstructures of composites were analyzed by means of scanning electron microscope (SEM) on perpendicular sections the images show the adhesion between the fibers and geopolymer matrix are very good and micro-cracks on both cross-sections and surfaces of geocomposites are determined as inborn defects of inorganic matrix composites.

This industrial research was studied an improvement of efficiency in natural fiber production plant. The objective was improvement process by using IE techniques which this method was once green technology for industrial problems solving. Now process had build-up in process (WIP) due to unbalance times between trimming station and visual inspection of station. Therefore the research studied work of staffs; time study and data analysis through 5W1H were used for analysis of WIP root cause. The cause of problems founded were the transportation loss of between section had over necessity and loss of visual inspection for repair. Therefore it had bottleneck in process. Consequently the researchers applied ECRS in each working processed by separation of repair station. Repairs of items were isolated from the main flow path of the process. Calculating of work flow rate was used for identified operator for repair station. As a result of the above production improvement Times of visual inspection in a lot was decrease from 283.84 hrs to 160.19 hrs. It was decreased in 43.56%. In addition the effect of separation from the repair process made the total times of all process was decreased from 792.78 hrs/lot to 669.14 hrs/lot. It was decreased in 15.60% and decreased work in process had from 17 lots/day to no work in process.
