US 5433715 A
water-sensitive attaching means for securing together said carrier layers at substantially attached first zones thereof, said carrier layers having substantially unattached zones providing a plurality of pocket regions with said substantially attached first zones located between said pocket regions;
high-absorbency material located within said pocket regions to provide an absorbent laminate; and
secondary attaching means for securing together said carrier layers along selected secondary attachment regions and providing a substantially water-insensitive connection therebetween, said secondary attachment regions substantially restricted to locations spaced from said pocket regions;
wherein, said water-sensitive attachment means in said substantially attached first zones provides a wet strength adequate to hold said carrier layers together when wet, and wherein said wet strength is less than a separating force imparted by a swelling of said high-absorbency material when said high-absorbency material is exposed to an aqueous liquid.
2. An absorbent article as recited in claim 1, wherein said secondary attaching means is substantially restricted to an outer periphery of said absorbent laminate.
EXAMPLES Delamination Testing Procedure
______________________________________§ 4.1.1  Some of the specimens had a maximum load less than  15% of the upper limit of the loading range.§§ 4.2 & 6.1  Materials were conditioned for at least 2 days under  the conditions specified; however, they were tested at  laboratory conditions of 22 ± 2° C. and a relative  humidity of 50 ± 20%. Materials were tested within  2 hours of being removed from the conditioning room.§ 5.2  Unless otherwise specified, samples were cut into  102 mm wide test specimens, consistent with Note 6 in  the ASTM procedure.§ 5.3  The number of samples for each code is as given in the  data tables.§ 7.1  Head speed of 300 mm/minute was used.§ 7.3  Testing was done to a 60 mm length. The peak force  was recorded in Newtons. The peak force is then  divided by the width of the test sample to provide  force per unit width (N/cm).Note 10  Peak strength, energy, and average load were all  recorded. Note that average peel strength will have  little meaning in cases where the sample tears rather  than delaminates.______________________________________
