Investigations into the dimensional properties of knitted structures began with experimental works. Doyle [1], Munden [2], Knapton et al. [3,4] and Kurbak [5][6][7] gave some empirical formulas by conducting experimental works. At the same time, researchers also tried to create some geometrical and physical models for knitted fabric structures. Previously created geometrical models for plain knitted fabric include those of Chamberlain [8], Peirce [9], Leaf and Glaskin [10], Leaf [11], Munden [12], Postle [13], Kurbak [14, 15] and Demiroz [16].One of the most important extensions of a plain knitted fabric model is the application of the model to complex fabric structures which have miss and/or tuck stitches in their structures, as pointed out by Demiroz and Dias [17] and Kyosev [18]. Pioneering work to extend the model of plain knit to complex structures with tuck or miss stitches would be to have a miss or tuck stitch in a plain knit structure and to model the structural changes in these fabric regions. Thus, these basic works are the subject of parts IV and V of our work. This, the fourth part deals with miss stitch and part V deals with tuck stitch.During the work, we examined previous work on the geometrical modeling of plain knitted fabric to see whether one of these models could be used as a basis for our purpose. It is seen that Kurbak's 1998 model [15] is suitable.
Materials and MethodsIn this work, samples which included miss stitches were knitted on a manually operated 10 gauge Stoll V-bed knitting machine using 100% cotton yarn. After taking the samples from the machine, they were laid on a flat and smooth surface for 1 week in standard atmospheric conditions for dry relaxation. 1 After this period the photographs of the samples were taken to analyze the structure of miss stitches and their effects on surrounding plain knitted fabric loops (Figure 1).
AssumptionsIn this knit and miss model it was assumed that an area of eight courses by three wales of the plain knitted fabric part was affected by a miss stitch (Figure 2). There were seven courses at miss stitch wale that were assumed to be affected by the miss stitch and the wale spacings of these loops were taken to be equal to each other. The total fabric length of the seven loops of miss stitch wale must be equal to the total fabric length of the Abstract In this work a model of miss stitch and its effect on the plain knitted fabric structure are introduced for the first time, thus we present a pioneering basic work on knit and miss combinations. Photographs of knitted samples were taken and the assumptions of the model are based on these photographs. A geometrical model of this knit and miss combination is created and the model is drawn to scale. We show that these shapes are found to be exactly the same shapes as observed in real fabrics.
