Formaldehyde in Textiles Formaldehyde is released from some textile finishes, such as those conferring crease resistance, while the garment is new. These finishes are most likely to be used on fabrics that otherwise crease easily, such as cotton or wool. Formaldehyde is very water soluble, and washing the new garments before wearing will generally reduce the amount of formaldehyde released from the fabric.
