2 yarns and is essentially flat and smooth it defines the external surface 14 of the fabric strip 10 fig5 also illustrates the bar 6 yarns and their overlap portions 46 as well as segments of their underlaps 40 it should be noted that in fig5 the appearance of the bar 6 underlaps 40 is somewhat distorted from the appearance they would have in the composite fabric thus fig5 is somewhat diagrammatic and is intended primarily to illustrate the stitch pattern for the primary bar 1 and bar 2 yarns of the front panel the stitch configuration for the back panel may be seen from fig6 and 8 in which fig6 illustrates the back panel as seen from its underlap side from the left in fig7 in the back panel the bar 6 yarn 48 formed a continuous chain stitch along each wale for clarity of illustration the back panel the bar 6 yarn is illustrated in a manner which omits the connection of the underlaps of the bar 6 yarn to the front panel it will be understood that in the actual knitted fabric the underlaps of the bar 6 yarn in the back panel will have been drawn toward and knitted in.
