Abstract: The reed is among the necessary elements to complete the weaving process, due to which the interlocking angle between all warp and weft threads is 90 degrees in case of not changing denting throughout the weaving process. The aim of using the reed in the weaving machine has been to be a guide for passing the weft by shed in addition to beating up latter wefts to the former, as well as to maintain the width and keep woven warp density in lease rods. Hence the idea of research depends on the use of open reed, which is a comb with fixed lower (bottom) and an open upper part which can be opened and closed when changing denting during the weaving process. Several experiments have been carried out on the loom table equipped with four healds by using one warp, and the experiments have also been applied using plain weave 1/1 and twill weave 1/3. Experiments have shown that the change of denting during the weaving process makes it possible to change the interlocking angle between the warp and weft yarns to be less or greater than 90 degrees. New textile effects in a single sample design have also been obtained by making all factors invariable except the change of denting during the weaving process which was difficult to obtain by using the usual (closed) reeds. It was also possible to change the twill lines angle in a single sample of the twill fabric, and thus the open reed helps to get multiple textile and aesthetic effects.
