Abstract
Aqueous wax dispersions (G) comprising (A) a wax mixture of (A.sub.1) at least one non-oxidized paraffin wax with needle penetration (according to ASTM-D 1321).ltoreq.20 dmm and melting range above 65.degree. C. and (A.sub.2) at least one oxidized hydrocarbon wax with needle penetration (according to ASTM-D 1321).ltoreq.4 dmm and optionally (A.sub.3) at least one non-oxidized paraffin wax with needle penetration (according to ASTM-D 1321).ltoreq.55 dmm and melting range below or up to 65.degree. C. and/or (A.sub.4) at least one cationically modified oxidized hydrocarbon wax and (B) a cationic dispersant system and optionally (C) at least one softening and/or antistatic adjuvant and/or (D) a preserving agent or/and a defoamer. and/or (E) at least one amphoteric surfactant, are eminently suitable as finishing agents, in particular for yarns, in order to provide good slippage properties to the yarns finished therewith.
