|UNDERSTANDING THE CARE LABEL SYMBOL
The entire care label symbol system, as designed by the ASTM and approved by the FTC, is based upon five basic symbols which represent five basic care operations. These are: a washtub with a water wave for the washing process; a triangle for bleaching; a square for dying; an iron for ironing; and a circle for dry cleaning. Only one safe method of care is required on the label - usually either laundering or dry cleaning.
In addition, the "X" symbol can be superimposed on any of the symbols whenever there is evidence to support that using that process could damage the apparel.
