A distinctive absorbent article includes an absorbent core having multiple absorbent layers, wherein the absorbent layers interact in such a manner which preferentially locates absorbed liquid in an appointed, high saturation wicking layer. The localization of the liquid within this wicking layer increases the potential of this layer to move liquid through capillary action due to the higher saturation level and increased amount of liquid available. The intake capability of the absorbent system is maintained or improved over current systems by keeping a second layer of the absorbent system at low saturation levels through as many insults of the product as possible, while providing optimum intake performance through appropriate control of the composite properties. The low saturation in this layer provides void volume for the incoming insult as well, as a high permeability, thus increasing the intake rate of the absorbent system as a whole, but the structure of the low saturation layer is also balanced to provide an appropriately high level of capillary tension to provide enough control of the liquid to stop leakage from occurring. This low saturation layer is used in addition to a surge material and provides intake functionality in addition to that provided by the surge material. In particular aspects of the invention, the body side layer of the absorbent core does not extend over the entire surface of the overall absorbent core, therefore is not used as the high saturation, wicking layer, but as the intake layer. This arrangement also allows the intake layer to be in direct contact with the incoming liquid, therefore allowing for more immediate access and improved intake function.

In this embodiment, the resulting composite member can have a fast intake rate, less leakage, reduced rewetting, and reduced bunching and twisting.

The invention provides a method for treating cow dung with Hermetia illucens to prepare an organic fertilizer. The method comprises the following steps: dehydrating cow dung with a dehydrater; adding swill or kitchen waste of which the addition amount is 10-15% of the mass of dehydrated cow dung; and then adding lactic acid bacteria dry powder for fermentation treatment for 1-2 days, wherein the addition amount of lactic acid bacteria dry powder is 0.1% of the mass of dehydrated cow dung; and finally adding 3-4-day old Hermetia illucens larva, culturing for 5-6 days at 30-35 DEG C under the condition that the air humidity is 75-85%, and separating out mature Hermetia illucens larva, thus obtaining an organic fertilizer. The method has the advantages of high treatment capacity, short cycle and low energy consumption in the treatment process, and can be used for realizing the resource utilization of cow dung and kitchen waste and changing waste material into things of value. In addition, since the nutritional value of cow dung is higher than that of horse dung and lactic acid bacteria are used for fermentation treatment, cow dung becomes loose and is improved in palatability, the intake rate of Hermetia illucens is increased and the yield of mature Hermetia illucens larva can be improved by 50% or above. By virtue of the method, the environment sanitation is improved and moreover organic fertilizer and bioprotein are produced; and thus, the method has a very bright application prospect.
