A multi-structural filament comprises a single ingredient having two or more morphologies after extrusion through a die pack wherein one discrete region of the filament comprises one morphology of the ingredient and at least another discrete region of the filament comprises another morphology of the same ingredient, and wherein each region of the filament comprises at least about 7 percent of the filament. A process for the production of the filament is also described.

Single ingredient, multi-structural filaments

A polyester monofilament is formed from a high temperature polyester resin, a PET resin and a hydrolyric stabilizing agent, and exhibits increased resistance to hydrolytic and thermal degradation. The high temperature polyester resin can be blended with from 0 to about 5 percent by weight of a thermal stabilizing agent. In addition, a masterbatch including the PET resin and hydrolytic stabilizing agent may be compounded prior to blending with the high temperature polyester resin. A fabric may be produced having increased resistance to hydrolytic and thermal degradation and includes a plurality of woven polyester monofilaments, comprising a high temperature polyester resin, a PET resin and a hydrolytic stabilizing agent. Such fabrics have utility as fabrics for the dryer sections of paper making machines.
