One exception is with spandex. As little as 3 percent spandex will provide additional elasticity in a fabric. This required manufacturers and importers to attach care instructions to garments and to fabrics by the yard. The Rule was revised and clarified on January 2, 1984. As a result, consumers benefit from clearer and more complete care instructions required by this revision.
Common terms are to be used by the manufacturers.
The manufacturer is required to list only one method of safe care for the garment, even if other safe methods may also be used. The manufacturer does not have to warn you about other care methods that may not be safe. Some labels give both fiber content and care. It is important to read and follow the label. If no ironing instructions are given, it should not be necessary to iron the garment.
