Description
Technical field
The utility model belongs to property fibre and field of compound material, and in particular to a kind of fixed point absorption diamond shape
3D non-woven fabrics.
Background technique
It is continuous the problem of consumer feedback in use with being continuously increased for paper diaper popularity rate, it is most common
One of problem is exactly red hip, thus product further subtracts mainly around dry-ness and functional continuous upgrading
The contact area of paper diaper and time and affine skin after few skin and imbibition.Therefore can develop has fixed point assimilation effect
Nonwoven cloth cover, so that urine is only permeated and is absorbed in a region of paper diaper, reduce contact of the moist surface layer with skin
Area and time, and then reduce the possibility of red hip.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of fixed point absorption diamond shape 3D non-woven fabrics, the reality
With it is novel using diamond shape 3D it is compound can be further reduced liquid surface layer diffusion area and improve paper diaper it is dry-ness, can
The surface layer of amenities is disposably absorbed for paper diaper, sanitary napkin etc., adjustable point absorbs urine and quickly lower infiltration, keeps surface layer
It is dry and comfortable.
In order to realize above-mentioned purpose of utility model, the utility model uses following technical scheme:
A kind of fixed point absorbs diamond shape 3D non-woven fabrics, the non-woven fabrics include the non-woven fabrics upper layer stacked gradually from top to bottom and
Non-woven fabrics lower layer；The non-woven fabrics upper layer is weak close fibrous layer, and the non-woven fabrics lower layer is single parent's fibrous layer.
Further, the non-woven fabrics includes hollow structure and rolls point structure；The point structure of rolling assumes diamond in shape distribution.
Further, the weak close fibre fineness of the weak close fibrous layer is 2.0D, single parent's fiber of single parent's fibrous layer
Fineness is 2.0D.
Further, weak close 70-90 ° of water droplet contact angle of the fiber of the weak close fibrous layer, the list of single parent's fibrous layer
Close 40-70 ° of fiber water droplet contact angle, weak parent's fiber and single parent's fiber are hydrophilic fibre.
Further, the weak close fiber layer thickness is 0.41mm, and weak parent's fibrous layer grammes per square metre is 24.79g/m2, weak parent's fibre
The aspect ratio for tieing up layer is 3.4；Single parent's fiber layer thickness is 0.37mm, and single parent's fibrous layer grammes per square metre is 16.97g/m2, single parent's fiber
Layer aspect ratio is 5.58.
Further, the aspect ratio of the weak close fibrous layer is greater than 3.4, and single parent's fibrous layer aspect ratio is greater than 5.58；And it is weak
Thickness > 0.4mm of close fibrous layer.
Further, the non-woven fabrics passes through heat bonding, chemical adhesion and ultrasound by weak close fibrous layer and single parent's fibrous layer
The modes such as wave are combined with each other.
The utility model compared with prior art, has the following beneficial effects:
1. the non-woven fabrics that the utility model uses is two fibrous layer 3D composite embossed structures, upper layer is weak close fibrous layer,
Lower layer is single parent's fibrous layer, and vertically and horizontally strength is more larger than difference between two fibrous layers.The mixed and disorderly degree of top fiber is high, whole fluffy
Pine, interfiber pore is uniformly fine and closely woven, is conducive to liquid quickly lower infiltration, and due to the weak close property of fibrous layer, water droplet is on surface
Certain hydrophobic property is presented when first contacts, is seeped under can accelerating when liquid measure is big, so a zonule when liquid contacts upper layer
Inside continue lower infiltration, is not easy to spread on surface layer.Lowermost fibre is bigger in length and breadth, and thickness is smaller, and more fiber is arranged in the vertical direction,
The effect that water conservancy diversion is also played during seeping under liquid, enables absorptive core to fully absorb, and lower layer's single parent's fiber passes through
After crossing multiple liquid feeding, surface hydrophilic finish is washed, and hydrophobicity improves, and has certain barrier action when bleeding back for liquid, because
This, which bleeds back, to be greatly reduced；
2. two fibrous layer of the utility model is embossed compound preparation absorbability surface layer through diamond shape 3D, rolling in diamond shape has sky in a little
Heart bulge structure reduces surface layer and the whole contact area of skin, and contact liq can be made because its gravity is through hollow bulge
It is quickly lower to seep.Since the convex-concave structure of embossing can will fail directly to absorb the lower liquid importing seeped at the salient point of contact liq at first
Surrounding recessed channel, liquid are reduced in the diffusion area of surface layer, and the contact area of liquid is increased, under liquid can be made quick in part
It seeps；
3. the utility model is directly compound by the 3D surface layer and absorptive core, to be embossed lower layer's substitution guide layer, it is conducive to paper
The lightweight of urine pants, and it is excellent dry-ness to have paper diaper, it can also be used to sanitary napkin or other disposable absorbent articles.
