ABSORBENT MATERIALS HAVING IMPROVED STRUCTURAL STABILITY IN DRY AND WET STATES AND MAKING METHODS THEREFOR

摘要

PURPOSE: An absorbent material having improved structural stability in the dry and wet states is provided, which is not subject to shifting of the absorbent gelling particles during or after swelling by fluids. Also provided are a manufacturing method of the absorbent materials, and the absorbent products comprising the absorbent materials. CONSTITUTION: The absorbent material is comprised of:(a) absorbent gelling particles comprising a water-insoluble absorbent hydrogel-forming polymer(WAHP; 50-90wt.%); (b) a polycationic polymer bonded to the absorbent gelling particles at the surface thereof(0.1-10wt.%); (c) glue microfibers dispersed in the absorbent gelling particles(1-10wt.%); and (d) a carrier layer bonded to the absorbent gelling particles through the glue microfibers(5-50wt.%); which is manufactured by apparatus of drawing 1.
