Description
Technical field
The present invention relates to a kind of composite non-woven fabric and method for making thereof, particularly relate to a kind of composite non-woven fabric that the layer of three-layer network at least of one deck air lay stratum reticulare is at least formed that contains.
Adhesive-bonded fabric has been widely used on household supplies and the medical supplies, for example diaper, cotton wool, operating coat or the like.Adhesive-bonded fabric can be by different fixed the forming of multilamellar stratum reticulare, for example, No. the 375664th, TaiWan, China patent gazette disclose a kind of spunbond-melt and spray the MULTILAYER COMPOSITE adhesive-bonded fabric, it comprises the stratum reticulare/spunbond web layer that melts and sprays more than spunbond web layer/one deck in regular turn, and wherein this average diameter that melts and sprays the stratum reticulare fiber far is narrower than the average diameter of this spunbond web layer fiber.This composite non-woven fabric has good effect aspect barrier, then still wait to improve as for other character.
Background technology
Therefore, primary and foremost purpose of the present invention is to provide a kind of composite non-woven fabric of novelty, can make the functional air lay stratum reticulare of apparatus on demand, so that composite non-woven fabric reaches difference in functionality.
Another object of the present invention is to provide a kind of preparation method of described composite non-woven fabric.
To achieve the object of the present invention, composite non-woven fabric of the present invention comprises that the three-layer network layer is fixed at least and forms that wherein one deck stratum reticulare is the air lay stratum reticulare at least, and one deck stratum reticulare is for being selected from spunbond web layer and melting and spraying stratum reticulare at least.
The present invention relates to a kind of composite non-woven fabric, it comprises: the three-layer network layer is fixed at least forms, and wherein one deck stratum reticulare is air lay (air-laid) stratum reticulare at least, and one deck stratum reticulare is selected from spunbond (spunbonded) stratum reticulare and melts and sprays (meltblown) stratum reticulare at least.
Composite non-woven fabric of the present invention can have various compound mode, for example, can comprise that an air lay stratum reticulare (being abbreviated as A), a spunbond web layer (being abbreviated as S) and melt and spray stratum reticulare (being abbreviated as M).One concrete composite non-woven fabric example comprises that in regular turn a spunbond web layer, melts and sprays a stratum reticulare and an air lay stratum reticulare, and forms the SMA adhesive-bonded fabric.Another concrete composite non-woven fabric example comprises a spunbond web layer, an air lay stratum reticulare and a meltblown web stratum reticulare in regular turn, and forms the SAM adhesive-bonded fabric.
Moreover composite non-woven fabric of the present invention also can comprise one deck air lay stratum reticulare and two-layer spunbond web layer.Concrete composite non-woven fabric example comprises a spunbond web layer, an air lay stratum reticulare and a spunbond web layer in regular turn, and forms the SAS adhesive-bonded fabric.
Moreover composite non-woven fabric of the present invention can comprise that also one deck air lay stratum reticulare, one deck melt and spray stratum reticulare and two-layer spunbond web layer.Concrete composite non-woven fabric example comprises that in regular turn a spunbond web layer, melts and sprays stratum reticulare, an air lay stratum reticulare and a spunbond web layer, and forms the SAS adhesive-bonded fabric.
Moreover composite non-woven fabric of the present invention can comprise that also a spunbond web layer, melts and sprays stratum reticulare, an air lay stratum reticulare, melts and sprays a stratum reticulare and a spunbond web layer, can form the SMAMS adhesive-bonded fabric in regular turn.
Air lay stratum reticulare among the present invention can use various fibers or powder to be raw material, gets through the air lay processing procedure.The raw material that is suitable for can be selected from paper pulp (pulp), NACF or granule or powder, surpass absorption macromolecule (superabsorbent polymer; SAP) fiber or powder, PUR fiber or powder, hygroscopicity fibre or powder, oil-absorption fiber or particle or powder, deodorization fiber or powder, and composition thereof.
According to the present invention, can be according to the demand of composite non-woven fabric, and select the functional raw material of tool to carry out the air lay processing procedure and obtain having functional air lay stratum reticulare, thereby it is functional to give composite non-woven fabric.For example, if the employed raw material of air lay stratum reticulare is paper pulp or the super macromolecule that absorbs, then can give the composite non-woven fabric absorbability.If employed raw material comprises the super macromolecule that absorbs of paper pulp simultaneously, then can further promote the absorbability of composite non-woven fabric.If the used raw material of air lay stratum reticulare is NACF (or granule or powder), then can give the composite non-woven fabric chemical adsorptivity.If the used raw material of air lay stratum reticulare is paper pulp and hot-melt adhesive powder, then can give stiffness.If the used raw material of air lay stratum reticulare is adsorbent fibers or particle, then can give chemical adsorptivity.
In the aforementioned SMA adhesive-bonded fabric, if the raw material of air lay stratum reticulare makes the absorbefacient material of apparatus (as the super macromolecule that absorbs), then the air lay stratum reticulare owing to the top layer can provide absorbability, and the stratum reticulare that melts and sprays of nexine has water proofing property, so this kind SMA adhesive-bonded fabric can be used as the cotton wool material.Again, in the aforementioned SAM adhesive-bonded fabric, if the raw material of air lay stratum reticulare makes the absorbefacient material of apparatus (as the super macromolecule that absorbs), then because the air lay stratum reticulare of nexine has absorbability, the stratum reticulare that melts and sprays on top layer has water proofing property, and therefore this kind SAM adhesive-bonded fabric can be used as the operation material.
Used spunbond web layer can be melt spinning macromolecule (melt spinningpolymer) among the present invention single composition fiber or biconstitutent fibre constitute, and melt and spray that stratum reticulare also can be the high molecular single composition fiber of melt spinning or biconstitutent fibre constitutes.
The melt spinning macromolecule that is suitable for is optional from polypropylene (polypropylene; PP), polyethylene (polyethylene; PE), poly terephthalic acid diethylester (PET), polybutyl terapthalate (PBT), polyacrylic copolymer (copolymer of polypropylene; COPP), the copolymer of poly terephthalic acid diethylester (COPET), the copolymer of polybutyl terapthalate (COPBT) and polyamide (polyamide).
When spunbond web layer of the present invention or the fiber that melts and sprays stratum reticulare during for two composition (bicomponent) fiber, this pair composition is optional from polypropylene (PP)/polyethylene (PE), poly terephthalic acid diethylester (PET)/polyethylene (PE), poly terephthalic acid diethylester (PET)/polypropylene (PP), polypropylene (PP)/polyacrylic copolymer (COPP), the copolymer (COPET) of poly terephthalic acid diethylester (PET)/poly terephthalic acid diethylester, and high-melting point polyamide/low melting point polyamide.
Biconstitutent fibre can comprise the composition of a more low-melting composition and a higher melt.At this moment, this fiber can be core-sheath-type (sheath and core type) or parallel type (side by sidetype).
Perhaps, biconstitutent fibre also can be superfine fibre (microfine fiber), as Splittable (split type) superfine fibre or fabric of island-in-sea type (sea and island) superfine fibre.
The invention still further relates to a kind of compound method of not knitting for preparing, it comprises:
Form three-layer network layer at least, wherein one deck stratum reticulare is the air lay stratum reticulare at least, and one deck stratum reticulare is selected from spunbond web layer and melts and sprays stratum reticulare at least.Then, with this fixed composite non-woven fabric that forms of three-layer network layer at least.The fixed processing mode of selecting for use is restriction not, optionally roll (water-jetentangling), ultrasound bonding (ultrasonic bonding), or high disturbance is bonding etc. from hot pressing bonding (thermo-bonding), hot blast adhesion (hot air-through), water.
