Non-Woven Fabric and Food Casing Which is Produced Therefrom and Which is Based on Cellulose Hydrate

Abstract

The invention relates to a viscose and resin-bound non-woven fabric based on cellulose fibres, which is cross-linked to a urea methoylol having a low-molecular weight and which does not react with itself, which has, preferably, a cyclic structure. The urea methylol is preferably, dimethylol-ethylene-urea, substituted, optionally, in 4- and/or 5-positions, more preferably, dimethylol-dihydroxy-ethylene-urea, a 1,3-bis-hydroxymethyl-5-(C1-C6)alkyl-tetrahydro-1H-[1,3,5]triazine-2-one, preferably, dimethylol-ethyl-triazinone, dimethylol-propylene urea, dimethylol-hydroxy-propylene urea or tetramethylol-acetylene urea. The humidity-resistant non-woven fabric can be used as a reinforcer in food casings based on regenerated or precipitated cellulose, in particular in cellulose fibre skins.
