Method of making an absorbent laminate structure
摘要:
The present invention provides a layered absorbent structure, the structure having an upper surface and a lower surface. The structure comprises:(a) n webs of fibrous material, n being an integer of two or more. The webs are layered such that there is an uppermost web, a lowermost web, n-2 intermediate webs, and n-1 interfaces of two opposed adjacent contacting surfaces of adjacent webs. Each of the interfaces has a surface area.(b) Absorbent particles forming a discontinuous layer at one or more of the interfaces.The opposed adjacent contacting surfaces at each interface where particles are present are substantially entirely frangibly bonded by fiber entanglement between the contacting surfaces. The particles are immobilized at said interface(s) substantially entirely by fiber entrapment.
