การพัฒนากระบวนการเชื่อมท่อทองแดงระบบสารทาความเย็นเครื่องปรับอากาศโดยใช้โต๊ะเชื่อมแบบหมุน
The objectives of this research are to develop the welding process of copper tube for refrigeration in air conditioner by using rotation brazing table. The key design is the use of rotary head for nitrogen and rotary head for cooling water in assembly jig nitrogen discharge to prevent the internal welding soot to remove the soot that may occur during welding from piping system and to cool down the profile quickly. The result of water cooling to prevent that damage due to the heat of welding. The result from designing and creating of rotation brazing table to substitute stationary welding found that there is the reduction of machine cost by 11.61% or 46000 Baht/machine reduction of usage space 8.75 square meters or 74375 Baht increase of productivity by 93.48% reduction of nitrogen consumption by 98.20% or 2593 Baht/month reduction of support tool in production 75000 Baht per one rotation brazing table reduction of tiredness from working by 30.24% or equal to 137 manual works per day and reduction of usage of consumable material that can cause of greenhouse gas in form of trash such as cloth glove 1.40 KgCo2 per year leather glove 12.5216 KgCo2 per year nitrogen gas 0.1784 TonCo2 per year and water 0.54 KgCo2 per year. All of these can support the competition and dynamic change of industrial air conditioner in the future sustainably.

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.

การพัฒนาลวดลายผ้าฝ้ายมัดหมี่ย้อมครามด้วยเทคนิคคณิตศิลป์ ประเภท Tessellation เพื่อออกแบบชุดโอกาสพิเศษ
The objectives of this research of 1) to develop weaving Indigo-Dyed mudmee cotton pattern with tricks Tessellation 2) to design special occasion dresses 3) to study the satisfactions of women in Bangkok with special occasion dresses by using weaving Indigo-Dyed mudmee cotton pattern with tricks Tessellation. Actions are carried out by studying concept from tricks Tessellation in order to design mudmee patterns in 3 patterns consisting triangle pattern square pattern and hexagon pattern and take them to natural indigo dye. Then woven fabrics for cutting special occasion dresses consisting cocktail dress formal evening dresses and informal evening dresses in number of 9 models. To study the satisfactions of women’s work in the age of 25-35 years old in Bangkok in number of 399 persons. Instruments for using are Questionnaires data analysis statistics percentage average and standard deviation The result found that the most of the samples reply to the questionnaires are in the ages ranging from 25-35 years being single working in private business enterprises earning from 15000 baht to 25000 baht per month holding bachelor degree being used or buy clothing from weaving Indigo-Dyed mudmee cotton. The points on the consideration for deciding to buy dresses are modernity pattern and the beauty.

การพัฒนามาลัยจากผ้าด้วยเทคโนโลยีการตกแต่งกลิ่น
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.
