Further, the three-dimensional raised textural structure wave-shaped of the composite intermediate layer web the upper surface and the lower surface,
In, the three-dimensional raised textural of composite intermediate layer web upper surface or lower surface by several along its length it is equidistant simultaneously
The striped set of arranging is raised, and any one of striped protrusion is to extend along composite intermediate layer web width direction.
Further, multiple striped protrusions of multiple striped protrusions and lower surface of composite intermediate layer web upper surface
Between be staggeredly arranged.
Further, the top end of any one of striped protrusion as with the first surface layer web or the second surface layer fiber
The binding site that the inner surface of net is mutually combined closely.
The utility model uses above-mentioned scheme, the beneficial effect is that: the upper surface of composite intermediate layer web and following table
Face is respectively formed presetting three-dimensional raised textural, and reinforces composite intermediate layer web using the first spunbond layer and the second spunbond layer
Stereochemical structure so that obtained non-woven cloth products have the characteristics that three-dimensional sense is good and fluffy degree is high.

Specific embodiment
The utility model is further described combined with specific embodiments below.
Referring to shown in attached drawing *, in the present embodiment, a kind of spunbond hot-wind nonwoven cloth with stereochemical structure includes
One surface layer web a1, composite intermediate layer web a2 and the second surface layer web a3, wherein first surface layer of the present embodiment is fine
Dimension net a1 and the second surface layer web a3 is that lapper is formed by spunbond web with spunbond machine.
The composite intermediate layer web a2 of the present embodiment is combined by least two layers of spunbond web, in order to make it easy to understand, this
Embodiment is made of two layers of spunbond web, wherein two layers of spunbond web layer be by two groups of spunbond machines successively on same lapper
It is formed, to make two layers of spunbond web that compound arrangement up and down be presented, and two layers of spunbond web at this time is formation state.Pass through
Two layers spunbond web is imported in the thermoplastic baking apparatus being preset with, thus make the upper surface and the lower surface of two layers of spunbond web according to
The secondary thermoplastic by thermoplastic baking apparatus is formed, to enable two layers of spunbond web after hot wind penetrates sizing, surface on it
And lower surface forms scheduled cubic texture protrusion.The obtained upper surface composite intermediate layer web a2 of this implementation and following table
The cubic texture protrusion structure wave-shaped in face, if the three-dimensional raised textural of the composite intermediate layer upper surface web a2 or lower surface by
The dry striped being equidistantly arranged side by side along its length protrusion, any one of striped protrusion are along composite intermediate layer fibre
Dimension net a2 width direction extends, secondly, the band of position of any face cubic texture protrusion is opposite in composite intermediate layer web a2
Should be recessed on another side, so that multiple striped protrusions of the upper surface composite intermediate layer web a2 and its lower surface
It is staggeredly arranged between multiple striped protrusions.By the obtained composite intermediate layer web a2 of thermal finalization, the first surface layer fiber
Net a1 and the second surface layer web a3 three import the plain weave baking apparatus being preset with together and carry out hot consolidation.In addition, any
Inner surface phase of the top end of one striped protrusion as binding site and the first surface layer web a1 or the second surface layer web a3
It combines closely, that is, mutually smart by the multiple binding sites and the first surface layer web a1 inner surface of multiple stripeds protrusion of upper surface
It is intensive to close, it is tied by the way that the inner surface of multiple binding sites the second surface layer web a3 of multiple stripeds protrusion of lower surface is mutually close
It closes, is sandwiched between the first surface layer web a1 and the second surface layer web a3 to realize composite intermediate layer web a2, and
And in plain weave baking apparatus in such a way that hot wind penetrates, so that three's hot consolidation obtains required compound nonwoven cloth together.
Due to the compound nonwoven cloth prepared during whole thermal consolidating not by mechanical presses, be located in the middle
Composite intermediate layer web stereoscopic effect is maintained, and can be consolidated using the first surface layer web a1 and the second surface layer web a3
The stereochemical structure of clamp layer nonwoven layers, to allow product to keep fluffy sense and be unlikely to deform.
The present embodiment is the prior art in above-mentioned used spunbond machine and lapper, and structural principle belongs to this field
Technical staff's common knowledge, is no longer repeated here.
In addition, understanding of the those skilled in the art to thermoplastic baking apparatus and plain weave baking apparatus in order to facilitate understanding, special
Relevant embodiment is enumerated to be further illustrated.
Thermoplastic baking apparatus: including thermoplastic cabinet and is set at least one intracorporal burr rotary drum of thermoplastic case, thus
It enables the spunbond web layer that is preset with pass through the fabric guide roll traction being preset with to import in thermoplastic cabinet and around wearing burr rotary drum.In order into
One step promotes the effect of thermoplastic shaping, and two burr rotary drums can be arrangeds in thermoplastic cabinet, make the upper surface of spunbond web layer with
Lower surface is successively in contact with the roll surface of two burr rotary drums respectively, thus using two burr rotary drums successively to composite intermediate layer web
The upper and lower surfaces of a2 carry out thermoplastic shaping to form presetting grain effect.The burr rotary drum circumferential surface of the present embodiment
Cross section is wavy.
Plain weave baking apparatus: by the applied Chinese patent 201620893049.9 of such as the applicant,
Baking apparatus disclosed in 201621220982.6, and the present embodiment is in order to further enhance the effect of drying, by drying
Two plain weave rotary drums are provided in case, in order to which spunbond layer is successively worn around the hot wind for wearing two plain weave rotary drums realization the upper surface and the lower surface
Saturating consolidation process, principle construction belong to conventional technical means, are no longer repeated here.
