The purpose of research is to study the carbon footprint evaluation of products for thread turned Tungsten Carbide 16ER60 of production. To assess amount of greenhouse gas emissions that affect the environment. The key component in the calculation include raw material production material energy and waste January 2018 and March 2019. The scope of the study is the assessment of Business-to-Business (B2B). From the assessment of the carbon footprint it was total of greenhouse gas was about 1.1559 Kg CO2e which was divided from raw material about 0.0118 Kg CO2e and production process about 1.1441 Kg CO2e. From the improvement reducing electricity of sintering furnaces machine and lighting system was reduce greenhouse gas emissions about 0.3249 Kg CO2e or decrease percent 71.88 CT

This study was an aim to apply lacing technique to produce yarn accessories for value added and developing the new products. It was a survey research by questionnaires tool. The study was divided into 2 steps. The first was collected the basis data for product analyzed and appropriate design to produce the prototype products. Thai traditional design was chosen to master design prototype as kanok naree kacha and krabi traceries. All of these traceries are gentle and shown as the Thai design. Kanok is a thai traditional style that it was chosen for a represent design and combine together with product design and decoration trend on 2013-2014 in Formal & Sugary style. The prototype products 7 collections: necklace earring and brooch. The prototype products were accepted from the sample group which they were very good in the factors of the beautiful technique the utilization and the quality of products. The prototype had price in range 801 – 1 300 Bath. The prototypes were adequate detail. From these results the prototypes were response with customer and make an alternative choice to increase the household income.

The purpose of this research was to design and develop products from polyester yarn scraps according to an eco-economic design concept. The workpiece is formed by the compression molding machine used in the industrial system. Researchers studied the waste materials used in various processes of manufacturing in textile establishments to increase their value by designing a new product or by developing polyester yarn scraps. According to the research process with the upcycle method that focuses on using resources for maximum value by turning the scarps into new products and eco-design concepts to increase the value of plastic polymer waste one of the concepts of resource efficiency (4Rs) by recycling and design process. The research focuses on the process of polyester yarn scrap forming especially from the textile industry with the potential to be re formed to create new products with beautiful shapes and unique patterns. From polyester yarn scarps through the extrusion process. By using the compression molding machine with a compression force of 80 tons the temperature range and the time are controlled appropriately. Under the mold prototype hat from or flash mold.

The objective of this study is to explore a method to improve UV protection and antibacterial properties of the cotton yarn surface to produce high-quality textile products. Cotton yarns were coated with sodium hydrogen phosphate magnesium chloride softener solution and 0 to 0.54 M of polyvinyl alcohol to hold surface yarns to the yarn body using the winding machine. The coated yarns were analyzed using Field emission scanning electron microscope Fourier transform infrared spectroscopy and UV-Vis spectrophotometer. Optimal results were achieved when coating with 0.45 M PVA exhibited UV protection was excellent protection. The cotton yarn coated 0.45 M polyvinyl alcohol displayed the antibacterial activity in the presence of Staphylococcus aureus and Escherichia coli was 87 and 91% respectively. The expected overall properties may open the way towards new applications of high performance fabrics leading to an innovative product development in the textile industry
