Absorbent Article Comprising Topsheet, Backsheet And Absorbent Core With Liquid Transferring Layer Near Backsheet.Absorbent absorbent /ab·sor·bent/ (-sor´bent) 1. able to take in, or suck up and incorporate. 2. a tissue structure involved in absorption. 3. a substance that absorbs or promotes absorption. Article Comprising Topsheet, Backsheet And Absorbent Core With Liquid Transferring Layer Near Backsheet: No. 5,891,120; Harry Chmielewski, assignor ASSIGNOR. One who makes an assignment; one who transfers property to another. 2. In general the assignor can limit the operation of his assignment, and impose whatever condition he may think proper, but when he makes a general assignment in trust for the use of to Paragon Trade Brands. Norcross, GA. Filed 6/9/97. Issued 5/6/99. An absorbent article having a liquid permeable topsheet, a liquid impermeable impermeable /im·per·me·a·ble/ (-per´me-ah-b'l) not permitting passage, as of fluid. im·per·me·a·ble adj. Impossible to permeate; not permitting passage. backsheet and an absorbent structure between them was recently patented. The absorbent structure includes a lower layer near the backsheet and an absorbent core positioned above the lower layer. The absorbent core, which is formed by cellulosic fibers from distributed particles of superabsorbent polymer Superabsorbent polymers (SAP) are polymers that can absorb and retain extremely large amounts of a liquid relative to its own mass. [1] Water absorbing polymers, classified as hydrogels, absorb aqueous solutions through hydrogen bonding with the water molecule. (SAP), has an elongated e·lon·gate tr. & intr.v. e·lon·gat·ed, e·lon·gat·ing, e·lon·gates To make or grow longer. adj. or elongated 1. Made longer; extended. 2. Having more length than width; slender. central portion with an absorbency under load (AUL) not less than about 12 grams. The absorbent core has an upper surface that faces the topsheet and a lower surface that faces the backsheet. The lower layer provides a means for transferring a liquid permeating the lower layer from the absorbent core to the lower surface of the absorbent core. The lower layer has a basis weight of not more than about 150 gpsm and has an AUL of not more than about 6 grams. |
