Abstract:
The invention relates to a method for producing multi-layered surface structures, particles or fibres. Said method comprises the following steps: the reactive polycarboxylic acid or a derivative thereof is applied to a flat, particle or fibre-shaped support material which already contains the groups which can react with polycarboxylic acid or a derivative thereof, in order to form a covalent connection or is initially provided with said groups; (b) the carrier material treated in step a is, optionally, heated to between 60 °C to 130 °C, preferably to 80 °C to 120 °C due to acceleration, completion or additional optimisation of the covalent connections; (c) cellulose is applied to the carrier material which can form a covalent connection with the polycarboxylic acid or the derivatives thereof. The invention also relates to the use of the inventive method for producing multi-layered surface structures, particles or fibres for hydrophilizing surfaces, in particular for promoting adhesion between hydrophobic and hydrophilic materials and to improve the washability of synthetic fibres. The surfaces which are hydrophilizied by said method form the flat, particle or fibre-shaped carrier material.

Abstract:
The process for producing multilayered sheetlike structures, particles or fibers comprises the steps of (a) applying a reactive polycarboxylic acid or one of its derivatives atop a sheetlike, particulate or fibrous carrier material already comprising, or previously provided with, groups reactive toward, capable of covalent bonding with, the polycarboxylic acid or one of its derivatives, (b) if appropriate heating the carrier material treated in step (a) to a temperature in the range from 60° C. to 130° C. and preferably to a temperature in the range from 80° C. to 120° C. to hasten, complete or further optimize the covalent bonds, (c) applying atop the carrier material a cellulose capable of covalent bonding with the polycarboxylic acid or its derivatives. The present invention further relates to the use of the present invention's process for production of multilayered sheetlike structures, particles or fibers for hydrophilicizing surfaces, in particular for adhesion promotion between hydrophobic and hydrophilic materials and for improving the washability of synthetic fibers, the surfaces which are hydrophilicized by the process forming the sheetlike, particulate or fibrous carrier material.
