Switzerland-based Ciba Specialty Chemicals Inc. has developed Irgasurf HL 560, a hydrophilic
additive for polyolefin fibers and nonwovens, as an alternative to a topical finish.When added to
the polymer during extrusion, Irgasurf modifies the surface of the extruded polymer to give a
durable, wettable surface. Such a surface results in a more absorbent fiber, increases antistatic
properties and reduces friction, according to Ciba.
