Textile Fiber Materials

“…tearing, pressing) can release latent, time-dependent tensions in connection with moisture effects, causing changes in length. For further processing, especially in secondary spinning, knowledge of fiber length distribution is crucial to achieve high-quality fiber cohesion in the spun yarn [5].…”

“…If the regeneration is performed after coagulation, more rounded and less overlapped fiber cross-sections, as well as fibers (e.g. modal fibers) with a relatively homogeneous supramolecular structure across the fiber cross-section are created [5].…”

“…The bundle has a length between 200 and 1,400 mm, and a fineness of 1-4 tex. This technical fiber is extracted by means of a number of subsequent process steps removing vegetable glue, ligneous components, short fibers, and the marrow from inside the stem [1,3,5,7,57,72].…”

“…Fiber cross-sections are preferably created with a microtome and viewed microscopically under polarized light. The cross-section shapes of textile fibers are extremely varied and influence the processing behavior (primarily in secondary spinning) and application characteristics [2,5].…”

Modelling method based on idealised fibre bundles

“…In Fig. 10, the normalised result of the flat bundle test of cotton fibres (mean linear density of cotton fibres q f 51?9 dtex, 15 Upper Half Mean length5UHM5 27?2 mm) carried out by a SpinLab 900 HVI Fibrograph 16 is depicted (see the dotted line). The gauge length was l o 5(1/8)'53?175 mm.…”
