POLYESTER FABRIC FOR WATERMARK FORMATION PROCESSING

摘要

PROBLEM TO BE SOLVED: To obtain a polyester fabric for watermark formation processing to which is stuck a sizing agent containing an adduct of ethylene oxide to a polyhydric alcohol and a quaternary ammonium salt by dissolving only the objective part printed with the sizing agent for watermark formation processing by alkali weight reduction to give a fabric having formed a sharp watermark. SOLUTION: The polyester fabric for watermark formation processing to which is stuck the sizing agent containing the adduct of ethylene oxide to the polyhydric alcohol obtained by adding≥2 mols of ethylene oxide to the polyhydric alcohol and the quaternary ammonium salt.
