Heavy enzyme or vintage wash is used to get the old or used appearance. Garments are washed inside a washing machine with enzymes. Fleece sweatshirts are washed with a heavy enzyme. Enzyme wash is performed with a kind of live cell, which can break some of the fibers of fabric and can give the fabric a special effect, desired on the garment. Enzyme wash provides the fabric a soft, sanded or ‘peached’ effect that is very desirable on many garments. Enzyme wash is also useful for indigo denims. In this case, enzyme can replace stone but gives denim a stone-wash look, with a better and nicer blue and white contrast on the fabric. Enzyme wash is, however, costlier than stone wash.
