Non-woven webs of synthetic fibres consolidated by means of carboxylated styrene-butadiene
latices, and disposable articles made therefrom |
(57) A non-woven web of synthetic fibre(s) is characterised by consolidating (optionally
impregnating) the web (optionally 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.
