Abstract:The changs of stress state in cold rolled aluminium sheet with large pass reduction, the combining activation process of slip systems as well as the formation mechanism of corresponding shear textures were investigated. It is shown that the rolling deformation with large pass reduction produces not only the general rolling stresses but also a strong shear stress in aluminium sheet. With increasing additional shear stress the general rolling textures, i. e. {112}<111>，{123}<634>,  {110}<112 >  and  { 110} < 001 > decrease,and the shear  texture, i.e. {001}<110> as well as{111}fibre texture become stronger. The internal relation of these two kinds of textures was also discussed.
