Abstract

The present invention relates to polymer latex composition for fibre binding comprising: a) 50 to 98 wt.-% based on the total weight of latex particles in the composition of first latex particles having a volume average particle size of 80 to 1000 nm, wherein the first latex particles optionally bear functional groups and if functional groups are present they are selected from functional groups consisting of acid functional groups and salts, amides or anhydrides thereof, silane functional groups, and combinations thereof; b) 2 to 50 wt.-% based on the total weight of latex particles in the composition of second latex particles having a volume average particle size of 5 to 70 nm bearing epoxy functional groups, to the use of that composition for fibre binding, to a fibre structure comprising the dried residue of that composition and to a method for increasing the strength of a fibre structure.
