Behind the Scenes: Getting to Know Combers and Their Importance in the Textile Process

‘Yarn structure’ is an undefined idea, and can only be described with difficulties. An extraordinary good visual impression of the yarn structure is obtained by electron microscopy (SEM). The photo below shows a small piece of yarn appearing almost three-dimensional. The yarn structure is extremely impressively visualized. Comparison immediately reveals the clearer fibre arrangement at compact yarns, a distinct twist spiral and a small number of fibre elements which haven’t been sufficiently integrated. With a more orderly arrangement, a specific quality improvement is obtained which also occurs in staple fibre spinning. Fig. 4 demonstrates the two yarn structures according to SEM.
