In this paper, the specimens woven by the same weaver with identical materials but with four different types of knots, i.e., symmetrical, asymmetrical, jufti and U knots, which their details are given in a previous paper by these authors, are used. The effect of these knots on such physical properties as width of the weave, length of the motifs, length of yarn in a knot and the carpet weight are measured. The woven samples are produced in two different methods. Resulrs show that the width of jufti and U knot samples were reduced after cutting off the loom, while the change in the width of the other two is little. The change in the length of motifs depends on the change in the carpet length, i.e., in samples with change in carpet length, the motifs length change as well and in cases that there are little change or no change in the carpet length, accordingly no change or little change is observed in the motifs. In the meantime, by subjective investigation of shapes of motifs in the four different knots, the change in their details and the sharpness of the lines and curves in them are studied. The results of computation of the ratio of the wool yarn to cotton yarn demonstrates that in symmetric and asymmetric samples more than two third of the carpet weight is built up by wool yarns, so that it is predicted that they have better mechanical function compared with other knots. Jufti sample has the lowest ratio of wool to cotton yarn, so it would show the worst mechanical performance.
