Definitions

  • wet acting slip agents which reduce the tendency toward the formation or stabilisation and consequently the marking of folds, in particular transport folds, and reduce the substrate/substrate and substrate/metal friction and consequently the tendency toward the formation and marking of chafe points, are employed in the corresponding process steps. It has already been proposed to employ wax dispersions of different types as lubricants (or slip agents) for avoiding the formation of transport folds or creases, e.g. as described in GB-A-2128202 or 2282153.

  • wet-acting slip agents in the treatment of textile piece goods in rope form or tubular form, particularly made from polyester fibres, in jet dyeing machines, where, for example, they do not hinder or impair the dyeing, but act surprisingly well and extremely superficially on the wet substrate as wet-acting lubricants in surprisingly high efficiency and yield, and further with a high degree of constancy and reproducibility of these properties, even if the products employed come from different lots and/or have been stored for a prolonged time.

  • hydrophobic moieties are built up by polyesterification with diols of type (A 1 ), with dicarboxylic acids of type (B 1 ) and/or respectively with hydroxymonocarboxylic acids of type (C 1 ), while hydrophilic moieties are introduced with components of type (A 2 ) or (B 2 ).

  • the esterification can initially be carried out under atmospheric pressure, for example in the presence of inert solvents or preferably in the absence of any solvents, in which case volatile by-products, for example unreacted starting materials and other volatile accompanying substances, can then be removed under reduced pressure.

If higher oligo-functional compounds of type (H) are employed, their molar ratio to the difunctional compounds (D) employed is advantageously kept low. It is in particular advantageous to select the respective molar ratios in such a way that no significant crosslinking takes place, principally in such a way that aqueous dilution of the product does not form gelatinous, irreversible agglomerates, but instead a dispersion or colloidal solution.

  • These molar ratios apply to the specific non-ionic polyesters from the said starting components; if other and/or further components are used for the production of the polyesters or oligoesters, the molar ratios should, if necessary, be adjusted or changed correspondingly in order to obtain the corresponding polyester or oligoester properties.
