The article takes into account various factors which effect the texture evolution in the Cu lines. We propose here an explanation for the formation of {111}< 110 > and {111}< 112 > texture in the Cu lines. The explicit role of principal stresses, shear stresses and dislocations is discussed. The influence of line spacing on strength of the {111}< 110 > and {111}< 112 > texture components is also demonstrated in relation to the dislocation density.
