Patent

CA 2489288

The invention describes compositions solid at 21 ~C for the finishing of nonwovens, comprising a) 5 to 70 % by weight of a component melting in the range from 25 to 37~C, chosen from the group of synthetic waxes, paraffins, fatty acid esters, polyhydroxy fatty acid esters, fatty alcohols, alkoxylated fatty acid esters, alkoxylated fatty alcohols and mixtures of these compounds and b) 5 to 70 % by weight of a component whose melting point is at least 5 ~C higher than the melting point of component a), and component b) is chosen from the group of polyhydroxy fatty acid esters, C14 fatty alcohols, C12 fatty acids, the alkoxylated derivatives of the fatty alcohols and fatty esters, and mixtures of these components, where the compositions additionally comprise as component. c) 5 to 25 % by weight of a crystallisation accelerator chosen from the group of partial glycerides, ethylene glycol diesters and polymeric waxes, with the proviso, that the crystallisation accelerator has a melting point in the range from 45 to 70 ~C, and the compositions comprise less than 5 % by weight of water.

L'invention concerne des compositions solides à 21 ·C destinées à la finition de non-tissés, qui comprennent: a) entre 5 et 70 % en poids d'un composant qui fond à une température située dans la plage comprise entre 25 et 37 ·C, sélectionné dans le groupe comprenant cires synthétiques, paraffines, esters d'acides gras, esters d'acides gras polyhydroxylés, alcools gras, esters d'acides gras alcoxylés, alcools gras alcoxylés et des mélanges de ces composés; et b) entre 5 et 70 % en poids d'un composant dont le point de fusion est au moins supérieur de 5 ·C à celui du composant a); ledit composant b) étant sélectionné dans le groupe comprenant esters d'acides gras polyhydroxylés, alcools gras C14, acides gras C12, les dérivés alcoxylés des alcools gras et des esters gras, et des mélanges de ces composés; lesdites compositions comprenant en outre c) entre 5 et 25 % en poids d'un composant accélérateur de cristallisation sélectionné dans le groupe comprenant glycérides partiels, diesters d'éthylèneglycol et cires polymères, à condition que l'accélérateur de cristallisation présente un point de fusion situé dans la plage comprise entre 45 et 70 ·C, et que les compositions comprennent moins de 5 % en poids d'eau.
