<p>PROBLEM TO BE SOLVED: To provide a cold reserving pillow capable of preventing dew condensation water generated on the cold insulator surface from oozing out of the pillow surface, even when a cold insulator is stored inside a pillow cover.SOLUTION: The material of a pillow cover including a storage part which a cold insulator can be taken out from and can be received into is formed as a three-dimensional knitted fabric. Especially, the distance between knitting yarns of a back knitted fabric constituting the three-dimensional knitted fabric, the thickness of a connection layer, a connection layer porosity and the aperture part ratio of a front knitted fabric are set within each specific range, to thereby suppress oozing of dew condensation water more effectively.</p> |
