Description
Technical field
The utility model relates to non-woven fabrics, more particularly to applied to the nothing with transparent liquid function of personal hygiene nursing materials
Woven fabric.
Background technique
In all kinds of personal hygiene nursing materials such as sanitary napkin, paper diaper, often need to use the cloth with transparent liquid function.
For this kind of cloth, people not only require it with good transparent liquid performance, and it is desirable that its pro-skin face be able to maintain it is dry and comfortable.Mesh
Before, the cloth that can reach this effect is all that can not reach this effect still using textile cloth made of Weaving method
And it is suitable for the non-woven fabrics of personal hygiene nursing materials.
The Chinese patent literature of Patent No. 201220103217.1 provides a kind of long fine spun-bonded non-woven fabrics, its main feature is that
Hydrophilic aids particle is buried in the single side fibrous layer of non-woven fabrics, is formed hydrophilic layer, is allowed the liquid to spread apart in hydrophilic layer
It goes, so that the fibrous layer for making the another side of non-woven fabrics not have builder granule is relatively dry and comfortable.However, this bury in fibrous layer is helped
The non-woven fabrics of agent particle can not accomplish lesser thickness, and the builder granule being otherwise embedded in fibrous layer is easy to fall off.Furthermore this
There are certain defects for the reliability of kind particle fixed form, are actually not particularly suited for personal nursing amenities.
Utility model content
The purpose of the utility model is to provide a kind of dry-touch type transparent liquid non-woven fabrics, which can reach good transparent liquid
Effect, and one side surface be still able to maintain after liquid penetrates it is dry and comfortable.
The utility model is realized in this way: a kind of dry-touch type transparent liquid non-woven fabrics, including by hydrophilic hot melt staple fiber group
At hydrophilic layer, by hydrophobic hot melt staple fiber group at hydrophobic layer, hydrophilic layer and hydrophobic layer stackup and be thermally bonded together,
The unilateral surface layer of hydrophobic layer composition non-woven fabrics.
The fibre length of one of embodiment, the hydrophilic hot melt staple fiber and the hydrophobic hot melt staple fiber is
10-100mm, fiber number are -15 denier of 0.5 denier.
One of embodiment, the hydrophobic layer with a thickness of 0.1-0.2mm, the hydrophilic layer with a thickness of 0.2-
0.4mm。
One of embodiment, every square metre 5-10 grams of the hydrophobic layer, every square metre 10-15 grams of the hydrophilic layer.
One of embodiment, the hydrophilic hot melt staple fiber are the hydrophilic hot melt staple fibers that contact angle is greater than 90 °,
The hydrophobic hot melt staple fiber is hydrophobic hot melt staple fiber of the contact angle less than 90 °.
The composition of one of embodiment, the hydrophilic hot melt staple fiber and the hydrophobic hot melt staple fiber is hot melt
Property plastics.
One of embodiment, the hydrophilic hot melt staple fiber and the hydrophobic hot melt staple fiber are skin-core structures
Low melting point composite short fiber.
One of embodiment, the core-skin composition of the skin-core structure are PE/PET or PE/PP.
The utility model has the advantages that having two kinds of fibrous layers of different nature of hydrophobic layer and hydrophilic layer, fall on hydrophobic layer
Liquid can penetrate hydrophobic layer under its self weight and guiding after spread by hydrophilic layer rapidly, in the single side surface of non-woven fabrics,
It is exactly that the surface of hydrophobic layer will not retain liquid, dry condition can be kept.On the other hand, the liquid spread in hydrophilic layer is still
It can so be detached from another side surface of non-woven fabrics, will not influence the transparent liquid performance of non-woven fabrics.The utility model does not need
Builder granule is buried in non-woven fabrics, particularly useful as baby paper diaper, adult diaper, sanltary towel and various absorption pads
Pro-skin fabric cloth.
Detailed description of the invention
Fig. 1 is the section structure exemplary diagram of non-woven fabrics described in the utility model.
Specific embodiment
The utility model is more fully retouched below with reference to relevant drawings for the ease of understanding the utility model,
It states.The better embodiment of the utility model is given in attached drawing.But the utility model can come in many different forms
It realizes, however it is not limited to embodiments described herein.On the contrary, the purpose of providing these embodiments is that making practical new to this
The disclosure of type understands more thorough and comprehensive.
One embodiment of non-woven fabrics described in the utility model as shown in Figure 1, the dry-touch type transparent liquid non-woven fabrics by hydrophilic layer 1
Formed with hydrophobic layer 2, hydrophilic layer 1 by hydrophilic hot melt staple fiber group at, hydrophobic layer 2 by hydrophobic hot melt staple fiber group at.Parent
Water layer 1 and hydrophobic layer 2 are laminated and are thermally bonded together.Hydrophobic layer 2 constitutes the unilateral surface layer of non-woven fabrics, and hydrophilic layer 1 constitutes nothing
The other side surface layer of woven fabric.As preferred forms, hydrophobic layer 2 with a thickness of 0.1-0.2mm, hydrophilic layer 1 with a thickness of
0.2-0.4mm。
The fibre length for constituting the hydrophilic hot melt staple fiber of hydrophilic layer 1 is preferably 10-100mm, and fiber number is preferably 0.5
- 15 denier of denier.The fibre length for constituting the hydrophobic hot melt staple fiber of hydrophobic layer 2 is preferably 10-100mm, and fiber number is preferably 0.5
- 15 denier of denier.The mass area ratio of hydrophobic layer 2 is preferably every square metre 5-10 grams, and the mass area ratio of hydrophilic layer 1 is often flat
10-15 grams of square rice.In hydrophilic layer 1, hydrophilic hot melt staple fiber is the hydrophilic hot melt staple fiber that contact angle is greater than 90 °.?
In hydrophobic layer 2, hydrophobic hot melt staple fiber is hydrophobic hot melt staple fiber of the contact angle less than 90 °.
The composition for constituting the hydrophilic hot melt staple fiber of hydrophilic layer 1 is hot-melt plastic.Constitute the hydrophobicity heat of hydrophobic layer 2
