Particle Containment and Immobilization in Roll Good Materials

Integration of functional particles such as superabsorbent or zeolite powders into a roll good provides a way of imparting a virtually unlimited range of desired properties to a two-dimensional structure. This paper examines and compares the efficiency of various powder containment methods and their effect on properties such as absorbent capacity and fluid permeability. Methods of particle containment and/or immobilization include particle-to-particle adhesion, particle-to-fiber adhesion, and powder entrapment between bonded fibers.
