การออกแบบและพัฒนาผลิตภัณฑสิ่งทอด้วยเทคนิคการพิมพ์เส้นด้ายแบบซิลค์สกรีนจากสีธรรมชาติ
The project of design and development of textile product using wrap yarn printing with natural dyes by silk screen technique. The purpose of this study was to find out the silk screen printing technique for patterning on Ikat or Mud Mee textile. Due to the complicated Mud Mee process for patterning the design on Mud Mee textile silk screen printing was chosen because of its convenience and rapidity. Silk screen printed on warp yarn with dyed weft yarn created the plain weave pattern. Pattern design was inspired by the natural form of vortex. Such form was applied with silk screen printing technique with extract of natural dye from jackfruit heartwood. The research showed that the product interested the sample was home textile product by using for bedroom which designed using home textile design principle. Three tone of color were chosen for warp yarn by screen printing technique such as red colour from lac blue colour from natural indigo and yellow colour from jackfruit heartwood . Weft yarn were dyed with lac and natural indigo using cationic agent. The cationic agent using before mordanting along with dying by 5 g/l aluminum potassium sulfate (alum) which is the best result because the outcome colors were intense and bright like vermilion and natural indigo. The color extracted from jackfruit heartwood was used for silk screen printing process. Color extracted from jackfruit heartwoodwas in the form of powder color integrated with 4% sodium alginate. The viscosity was optimize for printing. Printed warp yarn was dried at 120 °C. Weaving in plain weave pattern which created the strength structure of textile. Mordants with alum showed bright and intense color. The fastness tests were at good to excellent level for producing home textile product for bedroom application. From the questionnaire it was found that the satisfaction of the sample were as follows 54% printing fabric by printing of warp yarn is similar to Mud Mee weaving 58% textile made by printed warp yarn showed the identity of Thai color tone using for printing 80% weaving pattern design inspired by the form of vortex was suitable 84 % plain textile was suitable for weaving in the form of vortex 64 % the composition of the whole pattern of the products was suitable 86% the color of the pattern was suitable 70% the color of the weft yarn was suitable with the color of the pattern 76 % the size of the products was fitting and 92 % the products were suitable for the purpose of using.
การออกแบบลวดลายด้วยเทคนิคการพิมพ์ซิลค์สกรีนบนผ้าฝ้ายผสมใยกล้วย สำหรับชุดทำงานสตรี
The objectives of this research are 1) to design pattern by technique of silkscreen on the banana fibers integrated cotton cloth for women’s working dress 2) to design women’s work dress from cotton blended with banana fibers by technique of silkscreen for female workers and 3) to study the satisfaction of female workers for working dress which sewing from the cotton blend with banana fibers for female work uniform by technique of silkscreen. The samples of the study were 399 working females with ages between 21-60 years old in Bangkoks Sathon and Bang Rak district. The research instrument was the questionnaire and 12 prototypes of cotton blend with banana fibers for female work uniform by the technique of silkscreen consist of dress coat and skirt. The questionnaires were randomly distributed. The data was analyzed using statistical percentage mean and standard deviation. The findings indicated that the majority of participants were 21-30 years old with married marital status educated with Bachelor degree working in the position of employees and have the average monthly income of 15000-20000 THB. Most of the participants have never purchased or wore the dresses or attires made from cotton blend with banana fibers. The decisive reasons for purchasing the working uniforms were personal preferences the frequency of purchases was on the monthly basis and the prices of purchased working uniforms were between 500-1000 bath each. The analysis of the satisfaction of participants toward the working females suggested the triangle pattern dresses is at the highest satisfaction rate followed by the circle mixed and square pattern with the means of 4.47 4.42 4.26 and 4.07 respectively. The circle pattern coats is at the highest satisfaction followed by mixed triangle and square pattern with means of 4.314.22 4.21 and 3.87 respectively. The circle pattern skirt is at the highest satisfaction rate followed by the mixed triangle and square pattern with means of 4.18 4.04 4.00 and 3.82 respectively. It was found that every pattern received the high degree of satisfaction.

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.

Development of bone replacement material via nanohydroxyapatite crystal growth on silk fibroin fiber
The objective of this research is to propose a new way to fabricate a composite material for future bone replacement development via growing apatite crystal on silk fibroin fiber. Apatite crystallization on silk fibroin fiber was prepared by precipitation reaction between Ca(NO3)2 solution and (NH4)2HPO4 solution adjusted pH by NH4OH solution. In this work Effect of solution concentration and initial pH values was investigated on apatite crystals. Chicken eggshells were used as calcium source by heating sufficiently powdered eggshells at 1300 °C for 4 h to acquire CaO powders made Ca(NO3)2 solution by dissolving in 65% HNO3 solution. Prepared Ca(NO3)2 solutions were adjusted concentration as 3 levels and were adjusted different pH values of 7 8 and 9 respectively. For processing of apatite crystallization silk fibroin fibers were immersed in Ca(NO3)2 solutions for 30 min. After that (NH4)2HPO4 solutions were added in silk fibroin fibers immersed in Ca(NO3)2 solutions. Reaction time was fixed about 1 min before cleaning to remove impurity precipitates on surface of silk fibroin fiber. Finally apatite crystallization on silk fibroin fibers occurred. The obtained result can conclude morphologies of apatite crystals on silk fibroin fibers was sheets sphere and flower. Solution concentrations and initial pH values directly influenced on Ca/P ratio of obtained apatite crystals by Ca/P ratio increases as increased solution concentrations or increased pH values. Finally research silk fibroin fibers were woven as two patterns of plain weave and twill weave and they were investigated Young’s modulus and tensile strength. The result indicates that Young’s modulus of silk fibroin fiber sheets woven as twill weave and as plain weave were about 616 MPa and 425 Mpa and tensile strengths of them weave were about 40 Mpa and 72 Mpa respectively. The optimum condition of growing apatite crystals on silk fibroin fibers was sample of CP19. Design of silk fibroin fiber with plain weave was an optimum pattern for future biomedical applicaions.
