The creation of nightgown decorated by woven silk yarn scrap from Baan Krua Cottage Industrial Village in Ratchathewi Bangkok Thailand. Objectives are: 1) to study the weaving technique using the silk yarn scrap 2) to design a nightgown decorated with woven silk yarn scrap and 3) to study the overall satisfaction of nightgown designs which utilize silk yarn scrap. The sample population in this research is 250 women found on Silom Road central Bangkok. The research instrument is a questionnaire with 9 prototype nightgowns decorated with woven silk yarn scrap. The collection consists of 3 sets one set with 3 short nightgowns another set with 3 long nightgowns and the last set with 3 short nightgowns with long tails. The research methodology is to hand out the questionnaire to 250 non-specific women on Silom Road. Data analysis is done by statistic percentage average and standard deviation. Results of studying the survey show that most of the sample populations are women age between 31 -35 years old with bachelor degrees or the equivalent. Most are married and work as state enterprise officers. Incomes are between 20001 - 30000 baht. Most of them have bought a silk nightgown before and chosen to buy at department stores. The reason that they do not prefer silk nightgowns is because most in the current market are not innovative enough. Most of the sample populations have never seen a nightgown decorated with woven silk yarn scrap before. The results of studying the satisfaction of the sample population found that for the short nightgown set most of the sample population prefer number 2 standard deviation is 4.48. For the long nightgown set most of the sample populations prefer number 2 standard deviation is 4.44. And for the short nightgown with long tail set most of the sample populations prefer number 2 standard deviation is 4.46.

This research studies the development of fabric garland with fragrance addition technology by investigating the method of covering microcapsule fragrance on fabric which is the material of making garland. The result of the study shows that: The study of covering gelatin on polyester fabric shows that the small amounts of gelatin applied on polyester lower the strength of the fabric which is not suitable for marking garland. Due to the requirement of the strength in making garland by folding fabrics and passing them through thread into round shape lacking of the strength causes the difficulty for the making process. Gelatin provides stiffness and hardness to the fabric which is easy to form into various shapes. Before adding fragrance the result of stiffness test shows that the fabric has bending length of warp yarn at 5.9 centimeters and weft yarn at 4.1 centimeters; however after adding fragrance bending length of warp yarn is at 2.7 centimeters and weft yarn is at 1.9 respectively. Then the efficiency of covering microcapsule fragrance on fabric is tested by Scanning Electron Microscope (SEA). After adding fragrance the result shows that: (1) the numbers of microcapsule are higher (2) microcapsules form in round shape and (3) the size of microcapsules are similar. However after 30 day of applying microcapsule to the fabric it shows that (1) the numbers of microcapsule are lower and (2) microcapsules are not in complete round shape due to the deterioration. For the process of making garland with nonmicrocapsule and microcapsule fabric it demonstrates that microcapsule fabric does not impact the process of making garland but it adds the value for fragrance addition which is able to be considered as added value.

This research aims at studying the product development from Cattail flower paper for community economy by (1) studying the paper making process from Cattail flower (2) testing the efficiency of the paper made of Cattail flower (3) studying the product development process of Cattail flower paper and (4) propagating the knowledge on product made of Cattail flower paper for the community economy to the Women Group for Basketry Product Development in Laem Phak Bia sub-district Ban Laem district Phetchcburi province. The process of paper making from Cattail flower in its mature stage uses soda method in pulping process and hydrogen peroxide in bleaching process. Paper formation process has to be done on grate by (1) using 38 kilograms of fresh Cattail flower which requires pulp separation from the core of Cattail flower providing; 34.2 kilograms of fresh pulp considered as 90%—its average humidity at 51.04%; 3.8 kilograms of fresh core considered as 10% of the total weight (2) boiling in open system at 100 ºC for 3 hours with sodium hydroxide with the intensity at 4% 6% and 8% of its weight (3) bleaching with hydrogen peroxide with the intensity at 10% 20% and 30% of the weight of dried pulp; 2% of sodium silicate; 0.05% of magnesium sulfate; and 1.5% of sodium hydroxide at 100 ºC for 2 hours with the ratio of pulp and water at 1:15 (4) making paper with Thai traditional handmade method with the size of 72×84 centimeters then drying paper in indoor place in order to prevent paper contraction due to short pulp. The efficiency of the paper made of Cattail flower shows that the paper has average standard weight at 168.88 g2/m; average tensile strength at 26.40 N.m/g2; average tearing strength at 3.14 mN.m2/g; average bursting strength at 1.37 kPa.m2/g; average folding strength at 605; average luminance at 39.05%; average water holding capacity of dry weight at 395.65%; and total used bleach pulp at 69.90% of the bleached amount. The product development from Cattail flower paper has 3 types which are designed evaluated and suggested by the experts in accordance with the requirement of community on product development as follows: (1) Paper made of Cattail flower with various patterns; (2) Multi-purpose box made of Cattail flower and; (3) Flower made of Cattail flower paper. During 2 days of the training program the satisfaction of the 30 participants concerning the knowledge on product made of Cattail flower paper for the community economy of the Women Group for Basketry Product Development in Laem Phak Bia sub-district Ban Laem district Phetchaburi province shows that the participants who answer the questionnaire are extremely satisfied.

This thesis presents a method of compare the reducing high voltage source more than necessary to the pilot study two plants in case of load near power station the same distance but different. There are 2 methods first method reducing the voltage by adjusting tap transformer. Other method installed by voltage equipment. Regulator in a factory used 2 methods for measured the value of voltage before&after and continued to reduce the voltage until minimum loading that this factory can normal operate. From two trials we found that reducing the voltage by installation voltage regulator/voltage equipment can save more energy cost 10.23% than adjusting tap transformer that can save only 4.66%. And analysis of Specific Energy Consumption (SEC) by reducing the voltage level of the industry. Energy consumption kWh per 1 output (plastic bottles) Then lower from 0.119 kWh per 1 bottle remaining 0.089 kWh per 1 bottle This is in line with the energy analysis that main control electric power.
