การถ่ายทอดเทคโนโลยีการสร้างตราสินค้าและบรรจุภัณฑ์เพื่อเพิ่มมูลค่าผลิตภัณฑ์จากเศษวัสดุสิ่งทอเหลือทิ้ง
The research aimed to Technology transfer of fancy yarn production for producing fabric from textile material waste. The purpose is to technology transfer of fancy yarn production for producing fabric to people and community and to evaluate of technology transfer of fancy yarn production for producing fabric. The procedures were as follows target population for the transfer of knowledge and technology as Small and Micro community Enterprise--SMCE and individuals interested in Dang Dong sub-district Bang Bon district at Roi-Ed province. A total of 34 peoples and two days on 20 - 21 June 2557 and a satisfaction survey with a questionnaire after training. The data were analyzed using frequency percentage and mean. The results that general Information are female and younger than 21 years of education in elementary education as a student. A question that asking about their satisfaction with the course and to divide into three aspects: the purpose of the project The course structure and the contents of the course. The majority were satisfied with the very best. The purpose and the content are high level of satisfaction. In relation to technology transfer of fancy yarn production for producing fabric from textile material waste divided into three aspects: the process provides trainers and facilities was found that were satisfied at all of the 3 parts. The participants are mainly used to provide benefits to themselves for one month to apply the knowledge gained after the training. The participants modified using a new material and used local materials applied accordingly. Moreover a focus will be capped by the school to take courses and workshops and to teach another one for working out or as part of the courses taught at the school. Satisfaction with the benefits of technology transfer and utilization. Satisfaction at the highest level. The comments and suggestions of the participants found that they need for re-training again. They would like to have a longer period of training in order to gain more knowledge. All lecturer can transfer knowledge during the training as well.
Study of a small vacuum coating system for thermal evaporation
In this research we studied and fabricated a small vacuum coating system which is suitable for small pieces of the samples. It can help us to save in both cost and time for coating materials in each run. The home-built system consists of (1) a two-stage rotary pump used as a roughing and backing pump for a vacuum chamber and (2) a diffusion pump. The ultimate pressure of this diffusion pump is about 10-7 torr. From the result of testing the fabricated vacuum system it is found that the chamber pressure under the atmosphere can get down to 2.2 x 10-2 torr in 6 minutes by the rotary pump. The pressure inside the chamber is continuously lower to achieve 4.5 x 10-5torr in 30 minutes by the diffusion pump. Moreover we did further testing the system by coating pure aluminum (99.999%) on a Si (100) substrate using a resistive heater source made of tungsten with applied voltage and current of about 2.19 V and 110 A respectively. The aluminum surface has been investigated by SEM and AFM.
