[0343] Example 1: Breathable Dry Molding
[0344] A 175 gsm airlaid compact web (as described in Table 1) was used as the lower layer of the absorbent core. The 175 gsm airlaid lower absorbent member was cut into a dumbbell shape having a length of about 21.5 cm and a width at the transverse centerline of about 6 cm. The dumbbell lower absorbent member was placed on a backsheet (as described in Table 1) comprising a polymeric film provided with a contact adhesive. A molded rectangular rounded center strip of solid airlaid web having dimensions 18.7 cm by 3.7 cm was placed over the lower layer. The dense airlaid sheet is as described in the table and has a density of about 0.1 g / cc and a basis weight of about 175 gsm. Pull the sheet against it with vacuum pressure Figure 16 Molding was performed while hot air was applied to the web from a Variable Temperature Air Heat Gun No. 8977 manufactured by Milwaukee Electric Tool Corp. of Brookfield, WI. Vacuum w...
example 2
[0347] An absorbent article was made similar to Example 1 except that two molded airlaid webs were used to form the absorbent core. The upper layer has a basis weight of 225 gsm, and a density of 0.12 g / cc, while the lower layer has a basis weight of 175 gsm, and the same density of 0.12 g / cc. As described in Example 1, two webs were used Figure 16 The hot air unit is initially molded. The surface height of the molded airlaid web was about 6.5 mm and the thickness of the web was about 1.5 mm. After moulding, the upper layer was cut into a racetrack shape (rectangular with semi-circular ends) 202mm long and 54mm wide. The lower deck is cut in an hourglass shape 226mm long, it has end petals with a maximum width of 74mm, and a narrow midsection with a width of 64mm. The upper layer is centered over the lower layer, and the transport delay layer is placed between two airlaid layers. As listed in Table 1, the transfer delay layer was a 27.13 g / m 2 basis weight pink spunbond w...
example 3
[0350] The article was made according to Example 2, except that wadding cut from a layer of air felting was inserted between the upper absorbent layer and the transfer delay layer. The airfelted layer (comminuted bleached softwood kraft fibers deposited by air after hammering to form a layer of unbonded fluff) had a basis weight of 340 gsm and a calendered density of 0.17 g / cc.
