Description
Technical field
The present invention relates to disposable sanitary articles technical fields, absorb more particularly to a kind of fast guiding and return infiltration with anti-
Disposable absorbent article.
Background technique
Infant and other people that can't take care of oneself usually need to wear disposable absorbent article, such as paper diaper, paper
Trousers etc. are drawn in diaper, sanitary napkin, drawing, its object is to be storage excreta, and make the body of these excretas and wearer, clothing
Clothes, bedding etc. are kept apart, and the absorbing medium of disposable absorbent article is absorptive core, and conventional suction core is by Time of Fluff Slurry fibre
Dimension is blended with Super Absorbent Polymer Particles.Although however, due to conventional suction core have the advantages that quickly absorb,
It is returned simultaneously there is also liquid and seeps serious problem, therefore, gradually replaced with the excellent composite absorbent core for returning infiltration performance.
Currently, compound composite absorbent core has become the core material of the Chinese paper diaper market mainstream, almost instead of biography
Unite wood pulp core, drop resistant, not discontinue, do not rise stick together, ultimate attainment ultra-thin and favor by Chinese Consumer's.Current compound suction
Receiving core is largely 5 layers of structure: upper covering layer, lower covering layer and intermediate fluffy cotton, wherein the two sides of fluffy cotton accompany height
Molecule water-absorption particle, high molecular material main body are distributed between fluffy cotton fibre web, and outermost layer generally has nonwoven layer to carry out bound edge.
Optimization of each paper diaper manufacturer to composite absorbent core, predominantly the replacement Layer assignment up and down of high molecular material, fluting, in replacement
Lower caldding layer material, the fluffy cotton three-dimensional sense of fine tuning and gap size.And on the other hand, in overseas markets such as America and Europe, Japan and Korea S, because of tool
Having advantages, the conventional suction cores such as soft, quick liquid storage, low drain urine risk is still mainstream core.
As previously mentioned, although there is composite water absorbing core excellent returning to seep performance by there is also the technologies of high leakage of urine rate
Problem.The reason is that lacking a kind of medium-Time of Fluff Slurry fibre for playing absorption, temporary storage function in composite water absorbing core
Dimension.
Based on aforementioned reason, the comprehensive composite water absorbing core of the present invention, the respective advantage of traditional Time of Fluff Slurry core provide one kind
Fast guiding absorbs and the anti-disposable absorbent article for returning infiltration.
Summary of the invention
The present invention for existing disposable absorbent article due to using ultra-thin absorbent core existing for the technology of high leakage of urine rate ask
Topic provides a kind of fast guiding absorption and the anti-disposable absorbent article for returning infiltration.For this purpose, the present invention uses following technology
Scheme:
Fast guiding of the present invention absorb with the anti-disposable absorbent article for returning infiltration, including it is permeable top layer, impermeable
Fluidity lateral leakage protection layer, opaque liquid bottom, and the absorbent cores being set between permeable top layer and opaque liquid bottom, it is described
Absorbent cores by super absorbent resin layer, fluffy cotton layer, super absorbent resin layer by being formed by connecting under upper respectively, in the absorption
It is equipped with the villus pulp layer with a thickness of 0.2-5mm on core, and is connected as one by helical form hot melt adhesive layer with absorbent cores；It is described
Fluffy cotton layer is wavy fluffy cotton layer.
Preferably, herein in connection with by super absorbent resin between the fluff pulp fibers in villus pulp layer.
Preferably, the one or both sides of the villus pulp layer are provided with diamond shaped embossing, with a thickness of 0.5-1.5mm.
Preferably, further include clad, the clad from side circumferentially cladding by villus pulp layer and absorbent cores from up to
The composite absorbent core of lower overlapping connection, and be formed by connecting by helical form hot melt adhesive layer.
Preferably, the clad circumferentially folded from top to bottom by villus pulp layer, absorbent cores, villus pulp layer, absorbent cores by cladding
Close the composite absorbent core of connection.
Preferably, the conical through-hole on surface layer through the clad, bottom, the cone are provided on the clad
The cone bottom opening of shape through-hole is far from the villus pulp layer；It is provided in the clad close to the medial surface of the villus pulp layer thin
Water coating.
Preferably, between the every four adjacent conical through-holes be matrix arrangement, the hydrophobic coating with strip along
The longitudinal direction of clad extends, and is open circumferentially around the vertex of a cone of conical through-hole.
Preferably, the aperture of the vertex of a cone opening is 0.5-5mm.
Preferably, the helical form hot melt adhesive layer is made of the helical form hot melt adhesive tape of plural item, and every two adjacent
Interval width, which is provided with, between helical form hot melt adhesive tape is not glued area for 3-100mm.
The invention has the benefit that firstly, villus pulp layer have quickly absorb, interim liquid storage, and quickly lower can seep, energy
The phenomenon that enough leakages of urine for effectively avoiding existing disposable absorbent article from often occurring, red hip.Secondly, the taper being arranged on wrapping layer
Through-hole further improves the rate of Liquid Penetrant to villus pulp layer, and is absorbed by villus pulp layer and temporarily store immediately, avoids
Disposable absorbent article in use return milliosmolarity, improve dry-ness, improve the usage experience of disposable absorbent article.
