In order to test each sample, with each sample place one with the essentially identical Plexiglas's plate of sample size on.In order to proofread and correct the humidity value of each sample, except that the actual humidity curve that in one section previously selected interval, obtains, also obtained dried record value and wet record value simultaneously, described predetermined time interval is 10 minutes herein.

In order to obtain doing value, promptly the lower bound on the figure places pick off on the sample, makes the longitudinal axis of pick off vertical with the longitudinal axis of sample, and the end of optical pickocff and two edges of sample are extended equidistantly.Sample places and makes its lining side be affixed on substrate layer and optical pickocff towards Plexiglas's.From SBR open record instrument, pen is driven, and pen returns zero in 20 case marking districts then, and then monitor recovers SBR again, removes detector from sample.

Then, in the same position of carrying out dried value record, be the center radially with horizontal mid point with sample, place a stainless steel ring, 6 centimetres of described ring internal diameters, high 4 centimetres, heavily about 326 grams.Derive from Baxter Healthcare Corporation to 80 milliliters of the center of stainless steel ring impourings, Scientific Products Division, McGaw Park, the standard blood bank saline of Illinois (catalog number (Cat.No.) B3158-1).This saline solution is that stabilisation of not containing antiseptic etc. is oozed 0.9% saline solution.This saline solution is a room temperature (72～74) (22-23 ℃).This saline solution of 80 milliliters inclines rapidly to ring, promptly inclines on the lining side that absorbs sample.Saline solution is absorbed into the surface following (no unnecessary liquid keeps on the lining) of lining and afterwards, soon removes stainless steel ring, rapidly optical pickocff placed on the sample upper surface by above-mentioned same procedure, and from SBR open record instrument opening entry.It is 1 cm per minute that monitor is adjusted writing speed, and test was carried out 10 minutes altogether.Pen is lifted at end at ten minutes intervals, closes it by monitor is converted to SBR.Then, the sample upper surface put back to ring with preceding identical position, the impouring saline solution is so that sample is saturated fully again, the impouring amount be generally about 100 milliliters so that absorbent cores is saturated fully.Amount of liquid after soaking for the second time in the pad should be enough, so that optical pickocff causes small amount of liquid to be back on the surface.Remove ring again, place pick off by above-mentioned same way as in the same position of sample upper surface, the optical sensing part of pick off no longer includes the salt residue aqueous solution of measuring last time through wiping.Again from SBR open record instrument to recording status, perhaps monitor is by instantaneous driving, perhaps recorder chart moves around, with on profile-paper, stay the record or the position, represent sample fully by saturated measured value.After doing like this, each sample has a null value or does value (V _D), complete saturation value (V _s), and one section time dependent curve, it is from absorbing lighting of 80 initial mL of saline solution, and the point after ten minutes ends.

After collecting these points, apparent surface's humidity value is pressed following Equation for Calculating:

Wherein:

V _TIt is the value on the curve of a certain preset time;

V _DIt is the value on the curve when samples dried.V _DEqual 20 for all tested sample;

V _sBe when sample value on the curve when saturated.

Now referring to the curve in the accompanying drawing 2.As seen Procter and Gamble training pants has about 90% start-up phase to surface moisture.Kept this value at the 1st minute, then this value reduces to about 75% between the 1st minute and the 3rd minute.In ensuing 7 minutes, the percentage humidity value begins to flatten, and becomes 65% at 10 minutes end.So this product begins to wet, and keep continuously soaking.Otherwise the Kimberly-Clark Huggies  Pull-ups  training pants that can buy at present is very wet when beginning, and apparent surface's humidity value is about 94%, drops to 50% at 1 minute end then.In the time of 10 minutes, apparent surface's humidity value reduced to 35% low.So this training pants is in that to soak after drying with saline solution faster.

Training pants of the present invention shows as a kind of balance between other two kinds of products.Can find out that the curve of product of the present invention is between other two curves from the curve of accompanying drawing 2.By using the wet indication of Ahcovel  inorganic agent on lining material, the value on a few minutes of beginning inner curves keeps the much higher value of Kimberly-Clark training pants than at present, and reduces to a more acceptable value at 10 minutes end.In the time of 1 minute, training pants apparent surface humidity value of the present invention is about 80%.But this value has reduced to about 50% in the time of 10 minutes.

So as seen the invention provides a kind of personal care absorbent articles, it kept higher apparent surface's humidity at least in the time of 1 minute, then, in one quite short period, about 10 minutes, have and reduce to apparent surface's humidity value of about 50%, so just invented a kind of product, it has a kind of dry and comfortable sensation, dresses more comfortable in the time may changing the product of making dirty easily always.So the present invention all has practicality for all kinds of personal care absorbent articles.

After like this in detail the present invention being described in detail, under the situation of spirit that does not deviate from following claim of the present invention and scope, multiple change and variation all will be conspicuous.
