PROTEIN ADSORPTIVE CELLULOSE NONWOVEN FABRIC

摘要

PROBLEM TO BE SOLVED: To provide a porous cellulose nonwoven fabric having high protein adsorption power and made of micro cellulose fiber.;SOLUTION: A protein adsorptive cellulose nonwoven fabric satisfies the following conditions (1) to (3): (1) An average fiber diameter is 10 nm or more and 500 nm or less; (2) porosity P_av is 40% or more and 99% or less {where the porosity P_av means an average value of porosities P_i of equally divided 16 parts of a cellulose nonwoven fabric 20 cm square}; and (3) a water absorption rate W_av is 150% or more and 650% or less {where the water absorption rate W_av means an average value of water absorption rates W_i of equally divided 16 parts of a cellulose nonwoven fabric 20 cm square}.;COPYRIGHT: (C)2012,JPO&INPIT
