Abstract
A bleaching composition comprising a partially saturated carrier and a bleaching agent prepared by first mixing the dry carrier with the dry bleaching agent and then adding water while continuing mixing to produce a moist powder. This powder is used in a tumbler with at least partially non-synthetic dyed fabrics to dry bleach or fade the dye from the fabrics. Specifically, the bleaching composition is a mix of potassium permanganate as the bleaching agent and diatomaceous earth as the carrier and is tumbled with the fabric to remove the dye from the fabric. The tumbling causes repeated contact with the bleaching agent and removes the dye in the fabric.
Claims6
A method for preparing a powdered bleaching composition for fading a dyed denim fabric comprising the steps of:
- first mixing a first batch by combining a first diatomaceous earth powder carrier and a dry potassium permanganate bleaching agent;
- second mixing of the first batch with a liquid, wherein the liquid is water, the liquid of said second mixing being added in an amount not greater than the maximum amount that can be added while still maintaining a powder consistency to the first batch;
- and
- third mixing the first batch after all the liquid has been added, said third mixing continued until the liquid is uniformly distributed throughout the first batch.
A composition for dry bleaching a dye out of denim fabric to produce a faded look, consisting essentially of:
- a diatomaceous earth powder carrier capable of absorbing a liquid;
- 1/2-20% potassium permanganate;
- and water;
- wherein said powder carrier, said potassium permanganate, and water are physically mixed to form the composition, said potassium permanganate being 1/2 to 20% by weight of the composition.
