Description
Technical field
The utility model belongs to personal hygiene article field, and in particular to a kind of sanitary napkin.
Background technique
The sanitary napkin of existing ordinary construction is as shown in Figure 1, from top to bottom mainly including hydrophilic surface layer 1, absorbent core layer 2, preventing
The three-dimensional shield 5 of water layer 3, release paper 4 and the setting of 1 two sides of hydrophilic surface layer, 5 lower end of three-dimensional shield are indulged towards far from absorbent core layer
The direction of axis is laterally extended, and the part extended and waterproof layer are compound, most cuts pressing and forming through one afterwards.It, will when wearing
Release paper 4 is torn, and waterproof layer lower surface and underpants are pasted, and two sides bending is then coated underpants.Compound is the profession of the industry
Term can be the techniques such as hot rolling, heat bonding, gluing.
It is primarily present following defect in use:
1. in order to guarantee that sanitary napkin accomplishes that non-leakage menses, waterproof layer often select the air impermeability material of high grammes per square metre, and
The sanitary napkin of the prior art in terms of considering comfort level primary concern is that the comfort level of hydrophilic surface layer side, and the material of waterproof layer
Comfort level is poor, and water-resisting property also determines that waterproof layer is difficult to be prepared with flexible material.Waterproof layer be directly with underpants contact layer,
For women during wearing is walked about, the corner that waterproof layer generates after folding directly for a long time with skin of buttock friction, leads to skin
Skin rubs red and generates discomfort.When long-time is dressed, generated not since such airtight waterproof layer causes buttocks sultry
Comfort.
2. the existing usual hot rolling processing of sanitary napkin hydrophilic surface layer forms various thickly dotted bundle hole flower type structures, high temperature
It tends to occur melt at hot rolling point, so that hydrophilic surface layer feel obviously substantially reduces.Therefore, hot rolling surface layer is directly and skin contact
Pliability substantially reduces afterwards, and wearing comfort degree weakens.
3. conventional sanitary napkin absorbent core layer width is 65~85mm, panty crotch width is 65~85mm.In order to enable
The absorption area of sanitary napkin increases, and improves the leak resistance of sanitary napkin, first it is also contemplated that absorbent core layer is widened, once
Widening will be more wider than panty crotch.Since 5 lower end of three-dimensional shield extends outwardly, then bonded with waterproof layer, two sides bending packet
When covering underpants, two sides can be made to pull absorbent core layer, but since there are certain stiffness for absorbent core layer, it is tired just to will appear bending
Difficult problem.Therefore, widen absorbent core layer under the fault of construction of the prior art there are problems, so absorption area is small, leakproof
Performance cannot enhance.
Utility model content
In view of the above-mentioned problems, the utility model is intended to provide, a kind of soft comfortable, absorbent properties are good, leak resistance is good defends
Raw towel.
The technical solution that the utility model solves the problems, such as is: a kind of sanitary napkin, hydrophilic including what is set gradually from top to bottom
Surface layer, absorbent core layer, waterproof layer, and be set to the three-dimensional shield of hydrophilic surface layer two sides, the waterproof layer lower surface are equipped with the
One soft material layer, at least provided with hollowed out area at one on the first soft material layer；
The waterproof layer lower surface and the first soft material layer are compound, and waterproof layer lower surface is exposed from hollowed out area, are engraving
Empty region is equipped with the release paper with viscose glue, and release paper is bonded with the waterproof layer lower surface of mucilage glue surface and hollowed out area.
Above scheme adds additional the first flexible material to solve the problems, such as that prior art sanitary napkin is not soft enough
Layer, but flexible material is not easy to cut in processing, so to pass through hot rolling treatment, is more conducive to cut after hot rolling, cutting
Shi Buyi has fluffed silk.
In addition, general flexible material is made of staple fiber, if the viscose glue in release paper is transferred to the first soft material
On the bed of material, on the one hand it is difficult to be adhered to above flexible material；On the other hand, release paper being torn when use, it is interior to paste glue surface
After on trousers, staple fiber is easy to remain on underpants when removing.Therefore, in order to avoid both of these problems, by the first soft material
The bed of material passes through hollow processing, and waterproof layer partial region can be exposed after hollow out, may make the release paper with viscose glue in this way and prevents
The partial denudation region composite of water layer, the glue in release paper be transferred on waterproof layer and it is traditional release paper is compounded in it is anti-
The effect of water layer is identical.Moreover, hollow out position removes the puddle at hot rolling position in this way, overcomes newly-increased just at hot rolling position
The new defect of structure bring removes not soft position, guarantees its completely flexible performance.
Further, the second soft material layer is equipped between the absorbent core layer and waterproof layer.In sanitary napkin use process
In, both wings need bending down to coat underpants side.The design of second soft material layer so that after bending with skin contact
Face is flexible material, and comfort is stronger.
Further, the three-dimensional shield lower end has been laterally extended base portion, the base towards absorbent core layer longitudinal axis
Portion and the second soft material layer are compound, and compound position and the vertical range of three-dimensional shield lateral wall are X.
Preferably, the X is 5~20 millimeters.
In above-mentioned further improved plan, if widened absorbent core layer, so that in absorbent core layer width ratio
Crotch part is wide, and when wearing only needs the second soft material layer of bending and its following some materials.Due to three-dimensional shield and
The corner of two soft material layers would not pull absorbent core layer part, perfectly solving can not there is no bonding in bending
The problem of increasing absorption area, enhancing anti-leakage.
Specifically, first soft material layer and the second soft material layer be by least one layer of hot-wind nonwoven cloth, or add soft
Spun-bonded non-woven fabrics or spunlace non-woven cloth are constituted.
Preferably, the hydrophilic surface layer upper surface is smooth soft plane.That is hydrophilic surface layer is not needed as traditional work
Skill rolls conjunction or ultrasonic wave post-processing through any like that, can keep the pliability of original surface layer and core in this way, and enhancing is whole to wear
Wear comfort level.
Preferably, the waterproof layer is ventilative PE film or non-woven fabrics.Wearing can be can be greatly reduced using poromeric material
Feeling of oppression and heat in the process moisture can be discharged by gas permeability duct.
Preferably, guide layer is equipped between the hydrophilic surface layer and absorbent core layer.
The remarkable result of the utility model is:
1. add additional soft material layer, as long as keeping away so that the region with skin contact is wrapped up by soft material layer
Exempt from skin to rub red and generate discomfort.It is sultry and generate discomfort to avoid buttocks for waterproof layer good permeability.
2. the structure design of the utility model allows to increase the width of absorbent core layer, the absorbability of sanitary napkin is improved
Energy and leak resistance.
3. hydrophilic surface layer does not have hard to roll a little, soft comfortable degree is further improved.
