New development fiber material : use DoE approach to determine the best formula for blended fiber silk (Samiya Cynthia Riccini and Semi-Natural Fiber)

摘要

Many research studied the silk with the filament fiber, which mean if the cocoon broke due to the larva become butterfly earlier, the cocoon will become waste. This paper studied with the broken cocoon and show to spin and become more value-added products. The broken cocoon will be processed with mechanical spinning method in order to become more value-added product, the product is Silk Yarn Blended. The objective of this paper is to determine factor and find the best blend material formula to make a new development of yarn from the broken cocoon of Samia Cynthia Riccini worm, and make a qualified yarn. From the three experiment it appears that the unevenness and strength are increasing. Unevenness and strength have the highest frequency of occurrence so that it becomes a priority for completion. Quality of the yarn from experiment 3.1, 3.2, and 3.3 increase for strength which is good, and decrease for the unevenness which is also good, and the both of unevenness and strength, can meet with the standard requirement. The best formula of this research paper can be applied in the Textile Industry, and combined between silk and semi-natural fiber will be the best choice for production in the future.
