Low-energy disperse dyes in general are also used in pad/steam applications but do have limitations regarding washfastness as well as lightfastness. The main advantages of disperse dyes are their ease of application and the excellent coverage of yarn irregularities (barre).  This method is best accomplished using multiple-bowl, continuous dye equipment.
