Provided is a polyester binder fiber which contributes to produce a liber structure having a high strength. The polyester binder fiber may have a ΔH of 30 J/g or less which is calculated as a difference between a melting endothermic amount ΔHm and a crystallization exothermic amount ΔHc in a temperature elevation phase as recorded by differential scanning calorimetry (DSC) curve. The polyester binder fiber may have a ratio (a.sub.1:(a.sub.2+a.sub.3)) between a crystalline component fraction (a.sub.1) and a total amount of a constrained amorphous component fraction (a.sub.2) and an amorphous component fraction (a.sub.3) in the range of from 98.0:2.0 to 50.0:50.0 in which the crystalline component fraction (a.sub.1), the constrained amorphous component fraction (a.sub.2), and the amorphous component fraction (a.sub.3) are calculated from a spin-spin relaxation time T.sub.2 at 140° C. obtained by pulsed nuclear magnetic resonance (NMR) spectroscopy.

A thermally bonded filtration media that can be used in high temperature conditions in the absence of any loss of fiber through thermal effects or mechanical impact on the fiber components is disclosed. The filter media can be manufactured and used in a filter unit or structure, can be placed in a stream of removable fluid, and can remove a particulate load from the mobile stream at an increased temperature range. The combination of bi-component fiber, other filter media fiber, and other filtration additives provides an improved filtration media having unique properties in high temperature, high performance applications.
