Description
Technical field
The present invention relates to a kind of manufacturing method and apparatus of functional spunbond non-woven fiber network, belong to spunbond non-woven fiber network manufacturing technology field.
Background technology
Spunbonded nonwoven technology is a kind of take polymer chips as the technology that raw material makes nonwoven fibrous web material.This technology web material product has wide range of application because intensity is higher, permeability is better and cost of manufacture is cheap.Because polymeric material polypropylene has the performance such as good heat endurance and narrower molten limit, polypropylene PP is made to become the most frequently used polymeric material of spunbonded nonwoven technology.
This web material generally needs to be endowed that some are functional in the fabrication process, such as hydrophily, antibiotic property etc.This is the difficult point that spunbond non-woven fiber network manufactures, if can improve the hydrophily of spunbonded nonwoven PP web material by distinct methods or increase that other is functional, the Application Areas of so spunbond PP nonwoven fibrous web material finished product will significantly expand.
At present, conventional functional method of giving spunbonded nonwoven PP web material mainly contains two kinds, a kind of is be immersed in the solution of functional material by making spunbonded nonwoven PP web material finished product, after a period of time, web material is taken out, adopt drying mode to be removed by solvent again, the material obtained will have functional, as hydrophily etc.The advantage of this method is that method is simple, and with low cost, its shortcoming is functional is temporary transient; Another kind is by functional material and polymer P P sliced materials from the most head end feeding of spunbond process, and the final web material product manufactured like this has lasting functional.But the at high temperature sex change of some functional material, also some functional material can not melting, makes this technical approach there is larger limitation.
Summary of the invention
The technical issues that need to address of the present invention are: for giving spunbonded nonwoven PP functional method of web material in prior art, or functional persistence is lower, and product quality is poor; Or functional material at high temperature sex change, also some functional material can not melting, has very large limitation.
The present invention takes following technical scheme:
A manufacturing installation for functional spunbond non-woven fiber network, comprises spunbonded nonwoven filature fleece formation part 1, electrostatic spinning part 2; Described spunbonded nonwoven filature fleece formation part 1 comprises polymer chips material feeding part 1a connected successively, screw extruder 1b, melt flowmeter 1c, die-head combination part 1d, fiber draw unit 1g, spunbond final fiber accepts and output precision 1h; Described electrostatic spinning part 2 comprises the extrusion device 2a of functional material, spinneret orifice part 2b, positive electrode 2c, electrostatic generator 2d; Described extrusion device 2a is connected with spinneret orifice part 2b, and positive electrode 2c is relative with spinneret orifice part 2b, and electrostatic generator 2d is for providing voltage with spinneret orifice part 2b; By electrostatic spinning and spunbond melt, compound is carried out in the region between die-head combination part 1d and fiber draw unit 1g, and functional electrospun fibers looping, in the outside of spun-bonded fibre, reticulates looping.
Further, described fiber draw unit 1g is traction roller or air stretching device.
Further, described spinneret orifice part 2b comprises bull spinneret orifice.
Further, described positive electrode 2c ground connection.
Above-mentioned manufacturing installation carries out a manufacture method for spunbond non-woven fiber net,

After reaching stable spinning etc. spunbond spinning process, first open electrostatic generator 2d, then open extrusion device 2a and start from spinneret orifice part 2b extrusion solution, solution is drawn into nanofiber after being subject to high-voltage electrostatic field, looping, on spun-bonded fibre, forms netted looping compound;
Deng wrapper fibre after fiber draw unit 1g, on spunbond final fiber accepts and output precision 1h, form composite fiber web form be output, obtain functional spun-bonded fibre net materials.
The present invention adopts process complex method and unique consolidation method, those can not be compound in spunbond non-woven fiber network material by the functional material of mutability under melting or high temperature, web material is had durable functional, thus the shortcoming of two kinds of modes in avoidance prior art, obtain both advantages.Specific practice is, functional material is made nano-scale fiber state by electrostatic spinning technique, be compound in melt fiber in the melt refinement section of spunbond process, nanometer shape fiber is allowed to combine with netted looping form and spun-bonded fibre, form combination closely, enter in spunbond non-woven fiber network material product.
Beneficial effect of the present invention is:
1) functional material is dispersed in web material;
2) do not need by means of other intermediary, both adhesions are larger;
3) functional characteristic of web material is more durable;
4) the adding of functional material, the transparent performance of material can not be affected completely.
5) implementation method is easy, and web product function is lasting, and especially adapting to those can not the imparting of the functional material of mutability under melting or high temperature.
