Abstract
The utility model discloses a three -dimensional non -woven fabrics of trompil has four planes, and first plane comprises bulge's top, and the second plane is the plane of recess branch department, the recessed portion distribute around bulge, bulge's bottom and the bottom of the recessed portion continuous third plane of formation the second plane on have from the second plane to the three -dimensional trompil of the 3rd plane extend's infundibulate, the bottom of the three -dimensional trompil of infundibulate constitute the fourth plane. The third plane for continuous plane and be located bulge's the bottom and the bottom of recessed portion, both can have effectual supporting role to bulge, also can increase the area of contact volume with lower floor water conservancy diversion layer or absorbent simultaneously when processing absorbent article to the increase adhesion strength is difficult for causing the surface course to drop or shift when using.
Description
Technical field
The utility model is related to non-woven fabrics field, and more particularly to one kind keeps when in use three-dimensional shape, increases bonding strong
The perforate three-dimensional non-woven fabric of degree.
Background technology
With growth in the living standard, non-woven fabrics is widely used in the hygienic absorbent products such as physiological napkin or paper diaper
In.To improve the comfortableness of non-woven fabrics and skin contact, the contact area with wearer's skin is effectively reduced, increase body fluid pervious
Speed, reduces tide adhesion sense, accordingly, it would be desirable to carry out oozing raising passage under perforate is formed in non-woven fabrics, increases the concavo-convex knot of non-woven fabrics
Structure, reduces contact area, so as to occur in that the non-woven fabrics with concaveconvex structure and perforated non-woven fabric.The non-woven fabrics with wearer
The face of skin contact is embossed or perforate is processed and forms concaveconvex structure and perforate.China Patent Publication No.
CN103908376A, publication date on July 9th, 2014, entitled a kind of solid nothing with open-celled structure that utility model is created
Cloth is spun, this application case discloses a kind of three-dimensional non-woven fabric, elevated regions and sunk area and open-celled structure is distributed with, it is described each convex
Play region and there is fibre density gradient to sunk area, by the compressive property in high-density fiber region, maintain three-dimensional nonwoven
The obvious concave-convex effect of cloth, it is disadvantageous in that:Elevated regions rely solely on the high-density fiber of elevated regions lateral margin and carry out
Support, the 3D effect for keeping three-dimensional non-woven fabric, and the bottom of elevated regions when finished product is made are difficult under a certain pressure
Marginal portion and recessed area at grade, therefore when boning with guide layer or absorbed layer, due to bond area it is less,
Cause to be difficult bonding, easily come off when in use, shift, so as to affect assimilation effect.
Utility model content
The purpose of this utility model is to overcome prior art defect, there is provided a kind of three-dimensional concavo-convex holding effect is good, absorbs
Return soon and ooze low, the perforate three-dimensional non-woven fabric of displacement difficult for drop-off.
For achieving the above object, solution of the present utility model is:
A kind of perforate three-dimensional non-woven fabric, it has four planes, and the first plane at the top of bossing by constituting, and second is flat
Face is the plane residing for recessed portion, and described recessed portion is distributed in around bossing;The bottom of bossing and recessed
Continuous 3rd plane is formed on the bottom for entering part, is had in the second described plane and is extended to the 3rd plane from the second plane
Infundibulate solid perforate, the bottom of described infundibulate solid perforate constitutes fourth plane;Described the first plane and the 3rd
Fibre density between plane is less than the fibre density between the second plane and the 3rd plane.
Described the first plane and the second plane is hydrophobic plane.
The 3rd described plane is hydrophilic plane.
The first described plane is 0.2-5.0mm with the difference in height of the second plane.
The first described plane is 0.8-3.0mm with the difference in height of the second plane.
The described perforated area of infundibulate solid perforate and the gross area ratio of the second plane is less than 70 %.
The second described plane is 0.1-5.0mm with the difference in height of fourth plane.
The second described plane is 0.5- 3.0mm with the difference in height of fourth plane.
After such scheme, the beneficial effects of the utility model are:
Fibre density between first plane of the present utility model and the 3rd plane less than the second plane and the 3rd plane it
Between fibre density, both can ensure that the more fluffy softness of the bossing to be formed, when in use with contact human skin more
Comfortably, the easy sizing of recessed portion can be caused again and liquid is easier to be penetrated into up to absorbed layer;3rd plane is continuous flat
Face and positioned at the bottom of bossing and the bottom of recessed portion, both can have effective supporting role, together to bossing
When can also increase contact area with lower floor's guide layer or absorber when absorbent article is processed, so as to increase adhesion strength,
Do not easily cause surface layer when in use to come off or shift.And the infundibulate perforate for being located at the second plane both can be penetrated into accelerating liquid
Absorbed layer, can further increase the thickness of non-woven fabrics again, and serving prevents from returning the purpose oozed.

Side, opens light source, and adjusting light source to histogram during threshold values 95 has two crests to occur;
2nd, " collection image " icon is clicked on, focusing makes image reach most clearly effect, clicks on " freeze frame " figure
Mark, carries out picture collection.
3rd, " lasso trick Object selection instrument " icon is clicked on, chooses the bossing in analyzed area, then click on " analysis target
Choose and colour " icon, there is the dialog box of " analysis target determine ", adjust threshold values to 95, click on and determine.Click on " target
The icon of analysis ", the dialog box for " analysis result-visualization processing " occur clicks on " analysis " button, " individual event parameter point occurs
The dialog box of analysis ", selects " analyzed area area " as current computing option in computing option, clicks on " calculating " button,
Analysis result A can be shown in dialog box, A is analyzed area area;
Select " algebraical sum " as current computing option in computing option, click on " calculating " button, meeting in dialog box
Analysis result B is shown, B is the area of bossing.
4th, with step 3, the area of infundibulate aperture segment is chosen, and is selecting " algebraical sum " conduct to work as in computing option
Front computing option, clicks on " calculating " button, and analysis result C can be shown in dialog box, and C is the area of infundibulate solid perforate.
5th, the area and the gross area ratio=C/ (A-B) of the second plane of infundibulate solid perforate.
Fibre density size judges:
Because the fleece that perforate three-dimensional non-woven fabric A1 is consolidation is stood by the engagement porcupine roller and recessed roller of a pair of heating
Body formed processing and formed, it is believed that the fiber number gone up everywhere and fibre density before perforate three-dimensional non-woven fabric A1 is formed
All same, and formed after perforate three-dimensional non-woven fabric A1, the fibre density between the first plane 11 and the 3rd plane 13, second is flat
Fibre density between the plane 13 of face 12 and the 3rd changes before being relatively molded.Therefore it is fine in the case of fiber number identical
The size of dimension density depends on the size of thickness
Measured respectively between the first plane 11 and the 3rd plane 13 using the rectangular XTL-200 electron microscopes of model
Vertical range between vertical range and the second plane 12 and the 3rd plane 13, you can judge fibre density size.
