I work with a fibers of wild silk, fineness 1,07dtex, strength 26,90cN/tex, elongation at break 34,25 CN/tex. In hot water fibers are melt.
My problem: 200 caterpillar working nest, I need to make insulation of fibers.
Manual isolation is uncertain because it destroys the fiber.
Is there any chemicals (aqueous or oily base) that the fibers would not melt and allowed me the insulation fibers?
