The invention discloses a
nursing pad with a gradient absorption structure and a compounding process thereof, and relates to the field of
nursing pads, the
nursing pad comprises a flow guide
surface layer, an
absorption layer, a water locking support layer, a micro-channel layer and a PE film bottom layer which are sequentially compounded from top to bottom; the
absorption layer comprises low-crosslinking SAP and
fluff pulp, and the thickness of the
absorption layer is 3-4 mm; the water-locking supporting layer comprises highly crosslinked SAP, PVA fibers and
hot melt adhesive powder, and the thickness of the water-locking supporting layer is 2-3 mm; the density of the absorbing layer is 0.1-0.15 g / cm < 3 >, the density of the water locking supporting layer is 0.3-0.4 g / cm < 3 >, and the absorbing layer and the water locking supporting layer are used for forming a
density gradient structure from the absorbing layer to the water locking supporting layer. A gradient density structure of a
soft core and a hard shell is formed by constructing the rapid water absorption characteristic of low cross-linked SAP of the absorption layer and combining a rigid network of high cross-linked SAP of the water locking supporting layer and PVA fibers, the problem that the thickness of a traditional homogeneous structure is not uniform due to disordered accumulation of SAP is solved, and therefore the fitting performance of the nursing pad and the
skin is further improved; and the
pressure sore risk caused by
local pressure concentration is reduced.
