摘要

PROCESS FOR OPTICAL OPENING OF SYNTHETIC FIBERS OR NATURAL FIBER SYNTHETIC FIBERS, USE OF A TREATMENT BATH, TREATMENT BATH, AND USE OF A MICROEMULSION The invention relates to a method of optical fiber brightening or from synthetic fibers mixed with natural fibers by treatment in a treatment bath to which a microemulsion was added containing the brightening components in addition to water. The microemulsion contains nonionogenic detergents, ionic detergents, organic solubilizing agents and water.
