The existing paper diapers are more and more commonly used, the usage amount of the paper diapers is increased year by year, the paper diapers are a common disposable sanitary product particularly for the infants and the old people just after birth, the technical indexes of the paper diaper absorption performance assessment mainly comprise multiple absorption speed, slip and seepage time (rapid absorption capacity), seepage return amount, seepage amount and the like, and paper diaper manufacturers have strict requirements on the indexes, and adverse reactions such as red buttocks or eczema and the like of the infants can be caused because the indexes do not reach the standard.

At present, different measurement methods are used for measuring the technical indexes, the measurement of the absorption speed of the paper diapers is to lay the paper diapers on a flat plate, then a 1.2kg cylindrical barrel with the inner diameter of 45mm is placed at the central position of the paper diapers, a certain amount of physiological saline is measured by the cylindrical barrel and is put into the cylindrical barrel for timing, the timing is stopped after the liquid is observed to be absorbed, the same operation timing for the second time is started after waiting for a time interval, the method ignores the state of the paper diapers in normal use, and does not consider the arc state of the paper diapers in the test process. The indexes of the back seepage amount and the seepage amount of the paper diaper are that after a certain amount of normal saline is poured into the surface of the paper diaper, a certain amount of filter paper with certain mass is padded at the bottom and the absorption surface of the paper diaper, then a weight of 1.2kg and the diameter of 120mm is pressed on the paper diaper for a certain time, the mass of the filter paper is weighed after the time, the front and back mass difference is the back seepage amount and the seepage amount, and the real practical condition of the paper diaper is not considered. In the two methods, the state of the paper diaper in the actual use process is not considered in the measuring process, and the shape of the paper diaper when the paper diaper is contacted with the buttocks is not considered, the absorption time and the rewet amount of the paper diaper tested by the two methods do not consider the arc state of the paper diaper in the practical process, and the values of the absorption time and the rewet amount of the paper diaper when the paper diaper is flatly laid and unfolded are small, so that the error of the test result is large.
