A method for estimating the fat adsorption rate and a method for estimating the volume after fat adsorption of the nanofiber aggregate for fat adsorption and the nanofiber aggregate for fat adsorption.

摘要

PROBLEM TO BE SOLVED: To provide a nanofiber laminate for oil / fat adsorption in which an oil adsorption rate is secured and an adsorption rate is effectively increased, and a method for estimating the oil / fat adsorption rate and a method for estimating the volume after oil adsorption of the nanofiber aggregate for oil / fat adsorption. To do. SOLUTION: The nanofiber aggregate 1 for adsorbing fats and oils has an average fiber diameter d of 1000 nm or more and 2000 nm or less, and a bulk density ρ _b of 0.01 g / cm ³ or more and 0.2 g / cm ³ or less. is there. The nanofiber aggregate 1 for adsorbing fats and oils can secure the adsorption rate of fats and oils and effectively increase the adsorption rate. [Selection diagram] FIG. 9
