US 2025/0066965 A1 · POLYESTER NONWOVEN FABRIC WITH SUPPRESSED REDUCTION IN PHYSICAL PROPERTIES BY TUFTING PROCESS, METHOD FOR MANUFACTURING SAME, AND BACKING FABRIC FOR CARPET COMPRISING SAME

Abstract

The present invention relates to a polyester nonwoven fabric with suppressed reduction in physical properties by a tufting process, a method for manufacturing same, and a backing fabric for a carpet, comprising same and, in particular, to: a polyester nonwoven fabric in which, by controlling the physical properties of fibers of a first component filament and a second filament, a reduction in physical properties is remarkably suppressed before/after a tufting process, thus enabling the manufacture of a carpet backing fabric with excellent mechanical properties; a method for manufacturing same; and a backing fabric for a carpet, manufactured thereby.

Dependent claims

A polyester-based nonwoven fabric comprising:

a first component filament containing a first polyester having a melting point of 250° C. to 300° C.;
and
a second component filament containing a second polyester having a melting point of 160° C. to 220° C.,
wherein the stiffness before tufting process measured by the measurement method specified in ASTM D 6125-97 is 100 mg to 300 mg in both the machine direction (MD) and the cross direction (CD).
