A support comprising synthetic fibers; And a three-dimensional network interwoven with at least a portion of the fibers contained within the support. The three-dimensional network comprises a first polymer cross-linked by a second polymer; The first polymer is a polyamine comprising a primary amine group, the first polymer is water soluble and cationic; The second polymer is a water-soluble polymer different from the first polymer. The second polymer comprises repeating units comprising halohydrin and / or epoxide groups capable of forming covalent crosslinks with the primary amine groups of the first polymer. A low amount of crosslinking component is needed for high dye pick-up efficiency.
