The anisotropy of wrinkling of polyester, polyester@mdash;linen, and linen fabrics in standard conditions and in a maximally humid environment was investigated. It was shown that wrinkling of polyester fabric is close to isotropic, whilie polyester@mdash;linen and linen fabric exhibits anisotropy to a greater degree the higher the linen content is. An incrasei n the humidity increases wrinkling of the fabrics in all directions, the difference in comparison to the standard state is insignificant for polyester fabric, but is very pronounced for linen, and the blended fabrics fall in the middle.
