It is provided with guide layer non-woven fabrics, as shown in figure 1, the general surface of existing liquid permeability surface layer can be provided with raised 11 ' between absorber
So that this liquid permeability surface layer 1 ' can be preferably fitted human body skin, also can increase the contact area of liquid permeability surface layer 1 ' and liquid, carry
High imbibition utilization rate, in addition, can also accumulate Excreta between adjacent each raised 11 ', reduces the machine of Excreta and human contact
Rate, improves comfort.As Fig. 2, this is mainly become by each raised 11 ' molding in this liquid permeability surface layer 1 ' in prior art
The hot-pressing roller 2 ' that liquid permeability surface layer 1 ' lower surface after type is evenly equipped with raised 21 ' through a surface is hot-forming from the bottom up, adopts
This kind of technique obtains the projection 1 ' on liquid permeability surface layer 1 ' surface, its liquid permeability surface layer basal surface can have pit 12 ' that is to say, that
This projection is hollow, and hollow projection anti-reverse osmosis effect is bad, and by flexible type after human body lower compression, impact is using comfortable
Degree.
As Fig. 3, those skilled in the art in order to obtain above-mentioned solid projection, using surface uniformly dimpled pressure roller pair
The liquid permeability surface layer of forming is suppressed from top to bottom, and after making liquid permeability facing surface be subject to pressure roller extruding, the pit in pressure roller 3 ' becomes
The corresponding projection of type, although the projection of this kind of mode energy shaping solid, after the liquid permeability surface layer 1 ' outside projection is squeezed
Density can affect imbibition effect and rate of liquid aspiration, reduce the quality of disposable sanitary articles.
Content of the invention
For the problems referred to above, the present invention propose a kind of can on liquid permeability surface layer the above-mentioned solid projection of direct forming health
The forming method of articles for use liquid permeability surface layer, improves the yields of disposable sanitary articles, increased its market share.
For solving this technical problem, the present invention takes below scheme: the molding side of disposable sanitary articles liquid permeability surface layer
Method, including liquid permeability surface layer molding procedure, described liquid permeability surface layer molding procedure includes for fine fiber material passing through blowing device
Uniformly blow to the blows material process on forming bin from top to bottom and by negative-pressure adsorption roller, the fibrous material in forming bin is adsorbed
The fine fibre film molding procedure of molding, the roller surface of described negative-pressure adsorption roller is provided with forming cavity, and described forming cavity is provided with correspondence
The each raised attraction grooves of liquid permeability facing surface, the lower section side of described negative-pressure adsorption roller is provided with guiding output press roll.
Further improved it is: on described forming bin, the roller surface of corresponding negative-pressure adsorption roller is provided with and leads cotton wool brush.
Further improved it is: described blowing device includes hydroscopic high-molecular resin storage bin hopper, blows hopper and blow expects pipe cylinder,
Described storage bin hopper and blow and be provided with screw conveying device between hopper, expects pipe cylinder is blown in the described lower end connection blowing hopper, described blows material
Socket is provided with hot blast gas entrance, and the described axially free end blowing expects pipe cylinder is provided with least two blowing in ladder distribution
Material mouth.
Further improved it is: described liquid permeability surface layer molding procedure also includes superfine fibre film film formation process and should
Superfine fibre film is compounded in the liquid permeability surface layer compound working procedure of fine fibre film lower surface.
By adopting preceding solution, the invention has the beneficial effects as follows: the present invention is in the forming cavity table of negative-pressure adsorption roller
Face is provided with raised attraction grooves each for molding liquid permeability facing surface, and by the negative pressure of negative-pressure adsorption roller by each fiber
It is adsorbed in roller surface thus molding liquid permeability surface layer, this kind of forming method uniformly can form solid in liquid permeability facing surface
The projection of body, and the degree of compaction of liquid permeability surface layer is uniformly, imbibition effect is good, it is to avoid hollow projection anti-reverse osmosis effect is bad,
By flexible type after human body lower compression, the defect of comfort difference, increased the occupation rate in its market.
