Abstract

The present invention relates to a recording fabric comprising a substrate layer, and an ink receiving layer formed on one or both surfaces of the substrate layer and containing glycol-modified polyethylene terephthalate, and a manufacturing method of the recording fabric. A recording fabric according to the present invention does not require an additional printing layer and is excellent in chemical properties, mechanical properties and flatness, thereby preventing a spreading or breaking phenomenon of the recording fabric from occurring when using the recording fabric. Furthermore, a recording fabric according to the present invention is characterized in that the recording fabric does not emit endocrine disruptor and harmful gases during use, incineration or fire.
