However, it should not be washed at too high a temperature to maintain its quality. Bourette silk is best washed by hand or in the wool or delicates programme of the washing machine. Silk should also only be spun lightly so that the delicate fibres are not damaged. Like all silk fabrics, bourette is sensitive to alkali. Special silk detergents, on the other hand, are free of alkali as well as optical brighteners and enzymes, which can also damage the silk proteins.
