Abstract

A non-woven web of synthetic fibre(s) is characterized by consolidating (optionally impregnating) the web (option­ ally a dry web) with a binder (optionally a sole binder) substantially comprising a polymer or a latex, provided by polymerizing:
from about 42 to about 68 parts by weight of a monoaromatic vinyl or vinylidene monomer which may be unsubstituted or substituted by a C₁₋₄ alkyl radical, or a chlorine or bromine atom;
from about 30 to about 58 parts by weight of a C₄₋₈ conjugated diolefin (preferably a C₄₋₆ conjugated diolefin); and
from about 0.5 to about 8.0 parts by weight of a C₃₋₆ ethylenically unsaturated monocarboxylic acid. The resultant web can have improved tensile strength in a cross machine direction.
