Example 5
Embodiment 5 is basically the same as embodiment 1, and the description of the same parts is omitted, except that:
the flow guide layer is made of spun-bonded non-woven fabric.
In the invention, the performance test is carried out on the quick-absorption dry and comfortable absorbent articles of the embodiments 1 to 5, and the performance test results are shown in tables 1 and 2.
The test method comprises the following steps: taking animal blood for 2 times, each time is 5mL, the interval of 2 times is 10 minutes, and recording the time for completing each absorption as the absorption speed in unit of s; after 5 minutes of absorbing animal blood, a 1.2kg weight is pressed on 10g of filter paper and placed on an absorbing article (sanitary towel) for 1min, and the gram weight increased by the filter paper is weighed to be the reverse osmosis amount, unit g.
Test method two (bacteriostasis and odor removal test): and randomly finding 30 people to carry out bacteriostasis and odor removal effect test, and counting data results, wherein the results are shown in a table 2.
TABLE 1 results of the Performance test of the examples
Figure BDA0003243540890000191
The absorption rate and the reverse osmosis amount in table 1 were measured by test method one.
TABLE 2 results of the bacteriostatic and deodorant effects test of each example
Figure BDA0003243540890000192
As can be seen from the data in tables 1 and 2, the rapid absorption dry absorbent article of example 1 has a rapid absorption of animal blood, a good dryness, and a good bacteriostatic and odor-removing effect.
The invention has not been described in detail and is in part known to those of skill in the art.
