POLYESTER BINDER FIBER HAVING HIGH ADHESIVE FORCE
20230357961 · 2023-11-09 · ·

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.
