From Optical Image to Infrared Image of a very fine biodegradable spun yarn in cooling window of designed experiment

Basel Younes

Depending on extensive thermal analysis, a fine multi-filament yarn of 74 filaments, biodegradable aliphatic aromatic co-polyester yarn, are spun at 140 OC in melt spinning process. With original view, IR image illustrates the temperature variation to get the temperature profile scale along or across the fibres in term of investigation of cooling system quality, image colours correspond to the temperature scale on the right.
