Lectures: 1. Basic terms, characteristics and the four primary base weft knitted structures, threads used in knitting technology. 2. Basic parameters of knitted fabrics according the type and machine parameters. 3. Basic weft knitted fabrics - single-faced, double-faced and purl structures. Patterning with using the CAD software in knitting laboratory. 4. Other weft knitted fabrics - single-faced, double-faced and purl structures. Patterning with using the CAD software. 5. Weft knitting - patterning principles (needles partly out of action) with the CAD software 6. Weft knitting - patterning principles (float stitch) with the CAD software 7. Weft knitting - patterning principles (tuck stitch) with the CAD software 8. Influence of the patterning principle with miss stitch on the construction of the single and double-faced structures. 9. Influence of the patterning principle with tuck stitch on the construction of the single and double-faced structures. 10. Knitted patterning with the racking, loop transfer stitches, etc. in the CAD systems. 11. Principles of jacquard patterning with handle of V-bed rib flat machines, structures and their production. 12. Influence of the loop fabric construction on their knitted fabric properties. 13. Knitting to shape (fashioning), principles, possibilities and rules with using the CAD software. 14.

Learning outcomes
|
This subject follows on the subject Knitting. In the course the student obtains knowledge about the possibility of construction of threads in the weft knitting fabrics, the structure and patterning. Gradually, the structural and geometric characteristics of knitted fabrics are analyzed with regard to patterning with the needle function (miss, float and tuck) including the jacquard knitted patterning using CAD systems, and the effect of this patterning on the properties of the knitted fabrics. Furthermore, the possibility of producing knitted goods (products), special - fast starting courses and finishing (linking) directly in the machine for knitting machines with individual needle selection.
Basic orientation in the area of weft knitted patterning for clothing and technical applications. Specification and analysis of knitting structures, possibility of their production on the V-bed rib flat machines. Basic knowledge of design and pattern creation and patterning in CAD system for V-bed rib flat machines (patterning possibilities, shaping (fashioning) and production of knitted goods).
