Technical Field

The invention relates to the field of hygienic products, in particular to a universal diversion absorption core and a preparation method thereof.

Background

The paper diaper is a disposable sanitary product mainly formed by combining non-woven fabrics and an absorption core body, and the infant paper diaper is mainly used for absorbing urine of infants of 0-3 years old. Paper diaper generally comprises surface course, water conservancy diversion layer, core layer, ventilated membrane and bottom, wherein excision bar water conservancy diversion recess or water conservancy diversion indentation on the water conservancy diversion layer carry out the water conservancy diversion, and core layer itself does not possess the water conservancy diversion ability, and such finished product paper diaper, if too urgent or the urine volume of baby urine is too big, the water conservancy diversion is untimely, just has to play the risk of sticking together or even leaking urine, and the result of use is not good.

Disclosure of Invention

The embodiment of the invention aims to provide a universal flow-guiding absorption core and a preparation method thereof, which are used for solving the problem that the existing paper diaper is easy to cause lump formation and even urine leakage under the condition that the baby urinates too urgently or the urine volume is too large.
