Architectural fabrics were continuously developed on their unique performance. Architects and Engineers designed them for the application of important buildings around the world despite the symptom that Architectural fabric sizes from manufactures are smaller than the application sizes. Recently although the well-known method used to weld Architectural fabrics to enlarge their size is the high frequency welding there were some application issues. To mitigate those issues the researcher created the hot air welding to replace the high frequency welding in consideration on the failing loads of welded seams which are variable factors of the failing loads to indicate the weld strength and it is crucial for the Architectural fabric application. This research presents the comparison of failing load of weld seams between the hot air welding and high frequency welding by the test of Taguchis Orthogonal arrays L25 method. The test results demonstrated that Architectural fabrics welded by the hot air welding has the highest failing loads of wrap equal to 95.38 kN/m and the highest failing loads of weft at 86.17 kN/m. Conversely Architectural fabrics welded by the high frequency welding has the highest failing loads of wrap equal to 101.37 kN/m and the highest failing loads of weft at 97.78 kN/m. Based on a forementioned results there is no significant difference from both welding methods and thus concluded that the hot air welding could be used to replace the high frequency welding method.

The objectives of this study and product development of Thai Song Dam fabric womens bags were to study the cultural identity of the Thai Song Dam people to develop womens bags made from Thai Song Dam fabric and to study the satisfaction with the development of Thai Song Dam women bags products. The research instruments were an interview and a questionnaire for 80 women who were interested in Thai Song Dam fabric bags. The data were analyzed using a statistical package program such as frequency percentage mean and standard deviation. The results of the study on cultural identity of the Thai Song Dam people found that the dresses and souvenir products of the Thai Song Dam people have the most unique patterns to decorate the fabric which is embroidered with Piao flowers pattern. As for the development of bags made from Thai Song Dam fabric it was found that Thai Song Dam women’s bag are not produced. The researcher therefore studied by applying the patterns of womens bags that are popular today and applying the embroidered with Piao flowers patterns that are the identity of the Thai Song Dam people. As for the satisfaction towards the product development of Thai Song Dam womens bags it was found that overall product development satisfaction was at the highest level (x = 4.75 S.D. = 0.90). The overall satisfaction in sewing products was at the highest level (x = 4.64 S.D. = 0.39) and the overall bag product satisfaction was also at the highest level (x = 4.88 S.D. =0.32).

Native leftovers from tailoring that are unique create value and add commercial value. From the study of rags from local woven cloth left over from sewing Weaving indigenous fabrics which are local wisdom. Has been used to process various products such as clothing bags guards there will be a discarded part that is not used Therefore in this research the rag was used to develop the design of products for the elderly. There is a worthwhile use of local fabric scraps. focus on style Techniques for creating curved surfaces Embossed into a ball to create a texture and pressure. In terms of shape design it can be used with the elderly. can help and promote health in life Characteristics of the product is a product that can be administered to muscles. parts of the body of the elderly. The results of the experiment by bringing innovative products for the elderly from the waste of local woven cloth were tested on 22 elderly people in terms of form beauty function use. It was found that the elderly were satisfied with the innovative products for the elderly. with an average of 4.51 is the most innovative product for the elderly from various forms of local woven fabrics It is designed to be a guideline for application. production for sale This will result in the community learning to design products related to the elderly. Community can develop potential Community products and products for the elderly resulting in the creation of local product identity It is a process of creating a body of knowledge and extending local wisdom for benefits.

The attempt to fabricate gold films on glass slide (Au/glass) and silicon wafer (Au/Si) with gold leaf was unsuccessful due to poor adhesion between the gold leaf and substrates. Alternatively Au/glass and Au/Si films were fabricated by placing the substrate into the free space within sputtering chamber to collect the access Au vapor during the typical sputtering process for other samples. In this study the physical changes were observed in both Au/glass and Au/Si film under the film annealing from 300⁰C-700⁰C. The visual inspection via cell phone camera the micrograph via Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS) revealed the morphological changes with respect the annealing temperature in Au films due to solid state dewetting mechanism. The changes were more pronounce in Au/glass films than Au/Si films at the same annealing temperature. The X-ray diffraction measurement three phases of Au including Au(111) Au(200) and Au(220) in Au/glass films and one phase of Au(111) in Au/silicon films. The concentration and single crystallinity of Au(111) were increased with respect to annealing temperature in Au/glass film. For Au/Si films the concentration and single crystallinity of Au(111) were decreased at 300⁰C and then were increased at 700⁰C respectively. The physical changes of Au films are likely due to the movement of Au atoms via solid state dewetting and recrystallization. The heat intake from annealing process is likely induced the dewetting process by increasing the kinetic energy of Au atoms. While the recrystallization process is likely occur during the cooling period of the samples. Finally another factor that can affects the physical changes of Au films is the interface interaction between Au films and substrates.
