Abstract (en)
[origin: EP3476991A1] The present invention relates to a method of preparing non-woven fabric for base cloth of carpet, which has an improved fixability of BCF yarn inserted on a base cloth in a tufting process by crimp processing a web with a stretched polyester filament and needle punching the web. The residual stress of the stretched polyester filament is eliminated and the formability of the non-woven fabric for base cloth of carpet is improved, and the fixability of the BCF yarn in the carpet can be improved by interlacing of polyester filament.
