Description
Technical field
The present invention relates to a kind of amenities and its manufacturing methods.
Background technique
Amenities designs absorbent core layer as the main absorbent body of product, when wearing after liquid has touched surface layer under
Absorbent core layer is seeped into be absorbed.The product of current routine on the market, can have certain interval, especially between absorbent core layer and skin
It is night product, cannot be completely bonded, leads to the phenomenon that being easy to happen side leakage or front and back leak.
On the basis of this problem, some producers devised on product in male structure, it is real often to pass through following two mode
It is existing:
First way using such as blue chip, thickeies convexities material and the surface layers, absorptive core such as blotting paper, chopped blotting paper
Etc. the superposition of multilayers imbibition material, and the design of middle male structure does not jack up the absorbent core layer of main body imbibition on absorbent core layer
And achieve the purpose that quick imbibition, in addition, multilayer material is bonded by hot melt adhesive from top to bottom in the technique, influence sticky
Seeped under liquid, dry and comfortable performance is bad, and multilayer material bonding between gap or air communication channel it is narrow, be easy to cause product
Air impermeability from top to bottom easily causes sultry moisture in donning process.
The second way adsorbs Time of Fluff Slurry moulding process using mould wheel, forms part after demoulding in absorbent core layer and thickeies
Middle male structure, product made of such mode is not only thick but also hard, influences the comfort of wearing.
Therefore, it is necessary to provide the new amenities of one kind and its manufacturing method solution problem above.
Summary of the invention
The purpose of the present invention is to provide a kind of amenities of convexity layer soft, frivolous, dry and comfortable, comfort is high and its
Manufacturing method is particularly suitable for sanitary napkin.
The technical scheme is that a kind of amenities includes surface layer, bottom, the suction being set between surface layer and bottom
Sandwich layer is received, the absorbent core layer outer surface is coated with wrapping layer, and surface layer can be jacked up by being equipped between absorbent core layer and bottom, from
And form the convexity layer of bulge-structure in the middle part of surface layer.
By convexity layer design structure, in the middle part of absorbent core layer and its top surface layer structure jacks up, can will reduce surface layer with
Gap between skin so that excreta Rapid contact surface layer and be absorbed core absorption.With the middle male structure of routine on the market
It compares, absorbent core layer and skin contact area are bigger in the present invention, and product is more soft, frivolous, personal, and comfort obviously mentions
Rise, and because can sufficiently, quickly absorb excreta due to make product more dry and comfortable, and reduce excreta not in contact with absorber and
Caused leakage.
In a kind of specific scheme, the convexity layer is set between the bottom of wrapping layer and the inner surface of bottom.
In second of specific scheme, the convexity layer is set in wrapping layer, is located at absorbent core layer bottom.
In above-mentioned two kinds of schemes, no matter whether there is or not wrapping layer design, convexity layer is between absorbent core layer and bottom, it is therefore an objective to
By absorbent core layer protrusion.In addition, convexity layer can on-line machining or offline processing.
Preferably, the convexity layer is using soft or fluffy or have elastic material and be made.The non-of softness can be used
Woven cloths, which are made perhaps fluffy hot-wind nonwoven cloth and are made or have elastic PE material, to be made.
Preferably, the cross section of the convexity layer is a folding, eighty percent discount, three foldings or any one more compromised, and it is folded
Mode can be to be in the same direction or reversed, and folding effect can form structure type just or instead.
Eighty percent discount refers to c type structure as shown in Fig. 3 (a), and three foldings are such as 3(c) shown in s type structure.Folding effect can be formed
Structure type just or instead has Zheng Banbao, anti-Ban Bao, is just wrapping and instead wrapping entirely entirely.Wherein, anti-half packet refers to e type as shown in Fig. 3 (d)
Structure, just half packet with instead partly wrap it is contrary, anti-full packet refer to the side on the downside of anti-half packet is extended to it is concordant with cross-section lengths, together
Sample, the direction just wrapped entirely with instead wrap entirely it is contrary.Refer to that two ends folded are located at side in the same direction, reversely refer to two folded in the same direction
End is located at reverse side.
Preferably, the cross section of the convexity layer (5) is in turn connected to form by monomer structure or by multiple monomers.
Monomer structure refers to that as shown in Figure 3 multiple monomers are in turn connected to form can be as shown in Fig. 3 (e) for example by multiple
It is in turn connected to form in the monomer of olive shape.
Preferably, to block structure or continuous single structure.Interval setting can be longitudinally divided at it by referring to block structure
Two sections or multistage.For the longer night product of amenities, it may be designed as two or more part compositions.
Preferably, the longitudinal surface of the convexity layer is equipped with die mould lines or the perforation equipped with perforation, the die mould lines
For consecutive intervals straight line or interruption arrangement straight line or along longitudinal direction central symmetry distribution waveform curve.The die mould line
The longitudinal direction of curb convexity layer is extended.The perforation of perforation can be the equal arrangement form of vertical and horizontal spacing, or staggeredly
Arrangement form.
In addition, the convexity layer is also designed to meet the structure of other wearing comforts of ergonomics.
Preferably, the air hole of perforation is equipped in absorbent core layer；It is formed with and is rolled a little in surface layer, and roll a little battle array along longitudinal direction
Column distribution is at line or at face.
In traditional technology, the ventilative of product can only be played a role by the fiber gap of non-woven cloth, absorption of the invention
The improved air hole scheme of sandwich layer, increase broader gas-permeable channels, passes through the size and quantity of selection control air hole
It is how many to adjust gas permeability.
The lattice array of rolling forms hyperbola, and is symmetrical arranged along the longitudinal centerline.It is described double to meet ergonomics
Curve is the interior curved shape of similar X.
Preferably, three-dimensional shield is equipped in surface layer both lateral sides.
The present invention also provides a kind of manufacturing methods of amenities, comprising the following steps:
A, by convexity layer machine-shaping；
B, the air hole processing in absorbent core layer；
C, convexity manufactured in step A is placed under absorbent core layer, inside or outside wrapping layer；
D, the semi-finished product for forming step C and bottom are compound；
E, by step D-shaped at semi-finished product and surface layer it is compound；
F, finally, completing amenities manufacture.
Compared with the relevant technologies, the invention has the benefit that
One, finally absorbent core layer middle part and its superstructure are jacked up by convexity layer, reduce the gap between surface layer and skin,
So that excreta Rapid contact surface layer and be absorbed sandwich layer absorption,
Two, compared with traditional structure, contact area is bigger, and product is more soft, frivolous, personal, and comfort is obviously improved, and convex
The absorbent core layer risen can sufficiently, quickly absorb excreta, so that it is dry-ness and reduce excreta not in contact with suction to promote product
It is leaked caused by receipts sandwich layer.
