Abstract [en]

Knitting is a class of techniques for production of textile fabrics by inter-looping yarns with the use of hooked needles. The new loops are created when the yarns drawn through the previously formed loops. An apparatus for two needles with adjustable geometry resembling the knitting process in weft knitting machines has been constructed and mounted in an ordinary tensile testing machine in order to study stress build-up, fibre damage, needle wear etc. The merits of the knittability test-rig set-up are the possibilities to test the performance of the yarns with the geometry of the machine and to simulate and identify some of the problems that can occur between needles and yarn in the knitting process. Well-defined mechanical conditions with the static pre-load weight and the possibilities to identify the location of the events of damage on the fibres during the testing of the specimens and to do further examination before knitting are some obvious merits. The knittability of some extreme yarns, PET-monofilaments, carbon fibre roving and aramid yarn has been studied with respect to friction and bending stiffness. Friction and bending characteristics exhibit viscoellastic features. The needles have diameters of the same order of magnitude as the diameters of monofilaments for example for use in knitted spacer fabrics and the results of this work illustrate strong influence of the fibre diameter on the knittability.
