PURPOSE:To produce the title material which has a freely controllable water content and a large cold-reserving capacity and is flexible even at a temp. of refrigeration room and suitable for cooling a human body, etc., by mixing a highly water-absorbing resin with water and then with a water-insol. solvent contg. a surfactant. CONSTITUTION:The title material is produced by mixing 100 pts.wt. highly water-absorbing resin with 100-50,000 pts.wt. water and then with 10-300 pts.wt. water-insol. solvent contg. a surfactant in an amt. of 0.01-20 pts.wt. based on 100 pts.wt. water. Such two-step mixing enables the water content of the material to be freely controlled and gives rise to a cold reserving material which has a large cold-reserving capacity, is flexible even at-18 deg.C, and is suitable for cooling a human body, etc. |
