การพัฒนาคุณภาพเส้นใยไหมด้วยนาโนเทคโนโลยี เพื่อกลุ่มธุรกิจเกษตรกรเลี้ยงหนอนไหมจังหวัดสุรินทร์

รายงานวิจัย -- มหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร, 2562This research is to study the quality development of silk fibers by nanotechnology for the Silkworm farmer business groups of Surin Province. The research purposes are to study the efficiency and process of silkworm rearing using nanotechnology. To test the quality of silk fibers obtained from raising silkworms using nanotechnology. To compare of silkworm rearing results using nanotechnology and to transfer technology to improve silk quality with nanotechnology for silkworm farming business group in Surin Province. The results are as follows, 1. The researchers designed the recording schedule which the party can record the changes easily of silk worm development during each day. This research allows the researchers to collect data from the farmer is more easily and finely into 4 groups of experiments with 3 nanotechnology formulas: 1. ZINC OXIDE 2. SILVER NANO and 3. ZINC OXIDE and SILVER NANO with 50:50 percentages each. The silk used in the experiment was “Nang Noi” which is popularly silkworm variety in every household in Surin province.When experimenting must clean the house and rinsing the container with DI WATER for aperiod of 7 months 2. This research is divided into 4 groups. Group 1: Silkworm feed normal methods without the use of nanotechnology. Group 2 silkworms feed with Nano substances such as ZINC OXIDE, SILVER NANO, ZINC OXIDE and SILVER NANO in 15 percentage concentration. Group 3 silkworms feed with Nano substances are ZINC OXIDE, SILVER NANO, ZINC OXIDE and SILVER NANO with 30 percentage concentration. Group 4 silkworms feed with Nano substances are ZINC OXIDE, SILVER NANO, ZINC OXIDE and SILVER NANO with 45 percentage concentration 3. The Results and comparison of silkworm rearing using nanotechnology, the best formula feed is formula 1. When feeding Nano-sprayed on mulberry leaves using 3% 15% zinc, silver and silver zinc, it is found that the growth of worms in each age was good growth and not being a disease. Moreover, Silkworms are slightly better and more alert than normal farming. The length in ages 3 - 4 - 5 is going in a better direction. Amount of eating mulberry leaves in each age. As usually eating more in ages 2 and 3, after passing the silk production process and testing the quality of silk fibers in the laboratory were found that the silk fibers are smooth, not lacking toughness: Tenacity at 3.06 4.60 and 4.60, respectively, and also result in fiber amount increase, and also the color of the silk fibers is golden, quite clear, beautiful and consistent color. 4. When technology transfer to the Silkworm farmer business groups of Surin Province as workshop for 3 days. Most participants are satisfied with the highest levels in all questions.Rajamangala University of Technology Phra Nakho
