Scientific paper

Cosmological textures are known from numerical experiments to isotropise as they collapse. This article studies general energy configurations having the same form of energy density as do textures. Straightforward arguments based on an extension of Derrick's theorem lead to the conclusion that textures isotropise because they lose energy in doing so. The energy fraction lost in isotropisation is calculated. Since it is possible that some of the energy lost by macroscopic textures could be radiated as gravitational waves, this fractional energy loss estimates the maximal energy fraction which could be produced as gravitational radiation during texture isotropisation.
