| titleOfInvention | Method of preparing hydrogel structure |
| abstract | A method of preparing hydrogel structure, wherein the hydrogel structure comprises: (a) a one way penetrating polyurethane film layer, (b) a hydrophobic pressure sensitive adhesive layer, (c) a multi-directional elastic meltblown nonwoven, (d) an interpenetrating polymer network, and (e) a hydrophilic hydrogel; and the method comprises: (i) coating the hydrogel in a form of solution on the meltblown non-woven to form a product 1 , (ii) UV curing the product 1 in step (i), forming a composite comprising a hydrogel layer on the top, an interpenetrating polymer network in the middle, and a meltblown non-woven layer on the bottom, wherein the interpenetrating polymer network is a mixture of the hydrogel and the meltblown non-woven, (iii) providing polyurethane film layer coated with pressure sensitive adhesive layer, and (iv) laminating part of exposed fibers of meltblown non-woven with the pressure sensitive adhesive layer, forming a hydrogel structure. |
