Point, it is conceivable that waist elastic 15 can also be located at outside egative film, or, waist elastic 15 can also be single
Only elongated member is also connected on two longitudinal ends 9,10 of absorption pad 2 by conventional methods such as stitching, heat fuseds, this waist
The two ends of portion's elastic component 15 are equipped with connecting element 6 ', 6 ' or 6 ", 6 ".
The preferred embodiments of the present invention will be as a example by wherein belt and pad be bonded into hook-loop connection by hook element and loop member
It is described in detail, but, it is only exemplary that hook-loop connects, merely to the convenience described, should not be considered as this
The restriction of invention.It is true that hook element can be replaced by adhesive tab, and loop member is replaced with can tie with adhesive tab accordingly
The attaching surface closed.It addition, hook element and loop member setting on absorption pad and belt can also be exchanged.
The most illustratively describe and wherein there is hook element on absorption pad and belt self is constituted as integral loop element
The wearing process of the absorbent commodity that hook-loop connects.
First, first end (such as longitudinal end 9) of absorption pad is connected to belt.
Specifically, the waist elastic 15 on anterior 3 or rear portion 4 is the most manually stretched to a certain degree, so
After by hook element 6 ", 6 " be connected to belt 1, will hook element against belt.But, must when absorption pad is connected to wearer
Must carefully not want the health too extruding wearer.
When being discharged from pad by hands after the first end of absorption pad is connected to belt, the flexible member of stretching can produce one
The individual counteracting force acted on hook element, i.e. acts on the shearing force on each hook element.This shearing force enhances hook-loop even
The bonding strength (peel strength) connect.
Next the other end or the free end (being not attached to one end of belt, such as longitudinal end 10) of pad are moved through
Between two lower limbs of wearer.When carrying out this operation, in addition to the shearing force from above-mentioned waist elastic, there is no other masterpieces
The hook-loop being used in the first end connected connects.
This shearing force if from waist elastic is the lowest, then the bonding strength that hook-loop connects is the lowest, thus also exists
Connect the risk being disconnected, particularly when applying peeling force.
When the free end of pad moves between wearer two lower limb, peeling force is easy to be applied to hook-loop and connects, and makes hook unit
Part and loop member disengage.It addition, during the use of absorbent commodity, because the motion of the change of its weight and wearer is also
The disengaging of hook element and loop member may be led.
On the other hand, if waist elastic 15 stretches oversize the most by force and, then act on hook-loop connect on anti-
Active force also can be too big, and hook-loop can be made to connect disconnect because of the counteracting force of waist elastic 15 generation itself.
Final step is that the second end i.e. free end of pad is connected to belt 1.
Specifically, because the second end of pad include too being positioned at each corner hook element and be positioned at hook element it
Between waist elastic 15.This end connect by be connected to the first end belt identical in the way of carry out, i.e. by hook element even
Also will be by manual for waist elastic 15 horizontal stretch before receiving on ring material.Identical with the mode of the first end, by waist elasticity
The counteracting force acted in shackle connection of part 15 generation enhances these hook-loop and connects.
Preferably but not necessarily, the hook material during the hook-loop of the present invention connects for example, from Velcro " molding
Hook fastener " (seehttp://www.fasteningsystems.com/ultra_mate_ hth_hook.html), its thing
Product code is " ULTRA-MATE HTH847", wherein the density of each hook is 140 ± 14/cm2, and hitcher has so-called

Specifically describe below in conjunction with Fig. 4-8 how to carry out obtain waist elastic stretching produce shearing force and hook-
The method of testing of the relation between the peeling force that ring connects, the present invention obtains many concrete data by following test process.
The first step is to be connected to as shown in Figure 4 on loading material 22 by a piece of hook material 21.
Loading material 22 can be PE film, non-woven fabrics, cotton paper etc., and its intensity is sufficiently strong.Hook material 21 is by from hook material
Cut out 25x20cm size on volume to prepare, wherein a length of 25mm on longitudinal MD.Then by glued, double by using
Hook material 21 is connected on loading material 22 by face adhesive tape (such as Avery Dennison FT324) etc., and makes hook material 21 hold
It is oriented on carrier material 22 and makes it the most as shown in Figure 4.
It follows that prepare ring material 23 by cutting one section on ring material volume, then ring material 23 is placed on hook
On material 21, and ring material 23 is made to be oriented its horizontal CD and longitudinal MD as shown in Figure 5.
Just complete now a hook-loop and connect sample.
In a subsequent step, by weight 2kg, diameter phi be 95mm, length w be that the cylindrical weight 24 of 50mm is right
Hook-loop connects sample and applies pressure, and as shown in Figure 6, the surface of weight 24 is made up of rubber, and its hardness is 80 Shore A levels.
Cylindrical weight 24 connects on sample rolls forward the most again with the rolling speed of 300mm/min in hook-loop
Roll backward once, to obtain firm shackle connection sample.
Fig. 6 b is the sectional view along Fig. 6 a center line A-A, and as shown in Figure 6 b, hook element 21 (20mm width) has certain altitude H.
This means that whole weight 2kg of cylindrical weight 24 all concentrates on when cylindrical weight 24 rolls on hook material 21
On hook material 21 wide for 20mm.
By said method, the different samples representing different waist elastic force can be prepared.
In a subsequent step, the hook-loop of above-mentioned structure is connected sample applying shearing force, as illustrated in figs. 7 a and 7b.
Shearing force is applied perpendicularly to hook-loop by two clips and connects on sample, and first clamp 25 is connected to from above
Loading material 22, second clamp 26 is connected to ring material 23 from below.Weight 27 is applied vertical to second clamp 26 upper 60 second,
Then weight 27 is removed.In the present invention, the different samples representing different waist elastic force are applied different weights.In the present invention
In, it is preferable that sample is prepared as five groups, respectively to the shearing force often organizing sample applying 0g, 200g, 300g, 600g, 1000g.
Finally, hook-loop is connected sample and apply peeling force, as shown in Figure 8.Measure and hook material and ring material are divided by record
Open required power F (i.e. the peel strength of sample).In peel test force, use Instron, Lloyd extension test
Machine, its crosshead speed is 300mm/min.
Peel test force result under different shearing forces is listed in table 1-table 5.
