Abstract
It is possible to insert a real twist into continuous filament yarn through a false twist mechanism by godet spinning. The secret of this novel method is that not the twist inserted in monofilaments, but only the twist added to the filament bundle is recognized as a real twist. As the defects of this method, large accumulating ratio or overfeed and large loops projecting from the periphery of the yarn were pointed out. In this paper elimination of these defects were attempted by applying two methods of opening a multifilament yarn into monofilaments. Many factors which affected the operating efficiency and yarn properties were described. The yarn thus obtained was found to have much less snarling tendency compared to the conventionally twisted yarn. Properties of the fabric woven from the obtained yarn were similar to those from the spun yarn rather than to those from the texturized yarn.
