Title:
COMPOSITE POLYAMIDE POROUS FINE PARTICLE HAVING MOISTURE RETENTION, AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2009242518
Kind Code:
A
Abstract:
To provide a composite polyamide porous fine particles having both features of a polyamide porous fine particles and a moisture retention compound by an industrially easy method.
In the composite polyamide porous fine particles, the moisture retention compound is carried on the outer surfaces or/and inner parts of the pores of the polyamide porous fine particles having 1 to 30 m number average particle diameter, a ratio (PDI) of a volume average particle diameter to the number average particle diameter of 1.0 to 2.0, 0.01 to 0.5 m average pore diameter, 0.1 to 80 m2/g BET specific surface area and porosity (RI) of 5 to 100.
