Polyester articles

A nonwoven fabric formed according to the following method;

• melting a generally hydrophobic polyester to form a molten polyester;
• extruding fibers of said molten polyester under a pressure sufficient to cause the molten polyester fibers to undergo die swell immediately after extrusion;
• and
• applying a copolymeric material to said molten polyester fibers immediately after extrusion such that the molten polyester fibers are undergoing die swell at the time of application of said copolymeric material, said copolymeric material comprising a generally hydrophobic moiety soluble in said molten polyester and a generally hydrophilic moiety insoluble ins aid molten polyester.

A polyester article having a generally hydrophilic surface, said article comprising:

• a base polyester article formed from a generally hydrophobic polyester;
• and
• a copolymeric material melt fused to said base polyester article, said copolymeric material comprising a generally hydrophobic moiety and a generally hydrophilic moiety, said generally hydrophobic moiety being soluble in said polyester, said hydrophilic moiety being generally insoluble in said polyester;
• wherein said copolymeric material melt fused to said polyester is less fugitive compared to the same copolymeric material applied to the same polyester wherein the copolymeric material and the base polyester are not melt fused.
