초록

There is provided layer for personal care products made from elastic polymers that are extruded and cross-linked to form superabsorbents. Such a layer is useful in personal care products, like diapers, training pants, incontinence garments and feminine hygiene products.

대표청구항 ▼

1. A layer for personal care products comprising a superabsorbent acrylate-containing elastic polymer, which polymer is extruded and is dimensionally stable via an irreversible crosslinking reaction, and wherein such polymer comprises the product of a di or multi-functional hydroxy or amine terminated polyether or polyester polyol, coupled through isocyanates. 2. The layer of claim 1 wherein said elastic polymer is extruded in a form selected from the group consisting of fiber, film, foam, fibrous film and fibrous foam. 3. The layer of claim 2 wherein said form is fiber. 4. The layer of claim 1 wherein said polymer is made by reacting an amine or hydroxy terminated polyether polyol with water and an isocyanate. 5. The layer of claim 1 wherein said polymer is made from an acrylate and an isocyanate. 6. The layer of claim 5 wherein said isocyanate is selected from the group consisting of isophorone di-isocyanate and toluene di-isocyanate. 7. The layer of claim 1 wherein said dimensional stabilization is achieved by cross-linking by the use of a high energy beam. 8. The layer of claim 7 wherein said high energy beam is selected from the group consisting of electron beams and ultra-violet beams. 9. The layer of claim 1 further comprising additives selected from the group consisting of pulp, synthetic fibers, particles and mixtures thereof. 10. A diaper comprising the layer of claim 1. 11. A training pant comprising the fibrous layer of claim 1. 12. An incontinence product comprising the fibrous layer of claim 1. 13. A bandage comprising the fibrous layer of claim 1. 14. A sanitary napkin comprising the fibrous layer of claim 1.
