 Full text | Abstract: This article presents a geometrical model of three – and five–layer 3D distance knitted fabric which characterises the structural features of the fabric in a spatial Cartesian xyz system. New notions (technical terms) of ‘spatial a – jours’ and ‘spatial reliefs’ are introduced. Spatial a – jours are channelled layer structures inside knitted fabrics, whereas spatial reliefs are characterised by a different structure of the internal, as well as external layers, which are the result of a different thickness of the fabric layer’s segements. A hybrid model was developed of the graphical description of a 3D distance knitted fabric. This model includes a description of the thread continuum in the fabric stitch using of the 2D system. Whereas considered a solid, it presents the spatial architecture of the knitted fabric. The model composition was verified by an analysis of the real structures of twenty stitch variants. |
