Abstract
Non-woven fabrics of fibers, at least 50% by weight of which are hydrophobic, impregnated with a water-insoluble binder of a polymer derived from a monomer mixture of at least one mono-ethylenically unsaturated monomer selected from the group of acrylic and methacrylic acids and ester and amide and nitrile derivatives thereof, vinyl aromatic compounds, vinyl and vinylidine halides, vinyl esters of saturated carboxylic acids, polymerizable ethylenically unsaturated carboxylic acids and esters thereof, alpha-olefins, and diene monomers are disclosed. Optionally, the binder can contain a photosensitive compound of either or both the polymerizable and non-polymerizable types. The polymers are sensitive to radiation, such as electron beam and ultraviolet radiation, and readily cure to a crosslinked condition upon exposure to such radiation. The cured non-woven fabrics have sufficient wet strength and wet abrasion resistance for a variety of uses, for example, use as a durable or permanent fabric for covering mattresses and use as a non-durable or disposable fabric as is used in disposable diapers.
