Description
Technical Field
The utility model relates to a non-woven fabrics specifically is a novel ventilative, antistatic, antibacterial composite nonwoven fabric.
Background
The melt blown process is one of the polymer extrusion nonwoven processes, originated in the early 50's of the 20 th century. In the beginning of the 50 s of the 20 th century, the U.S. naval laboratory began to develop a filter material with a superfine filtration effect for collecting radioactive particles generated in a nuclear test, and the research result was published in 1953. In the mid-60's of the 20 th century, Exxon, Inc. further studied this process and worked with Accurate (Accurate) corporation to create the first meltblown equipment prototype and applied for patent. At present, in addition to the Exxon proprietary technology, other companies (e.g., 3M in the United states, Freudenberg, Germany, etc.) have also successfully developed their own melt blown nonwoven technology.
The existing melt-blown non-woven fabric has single function, and the existing non-woven fabric needs to be researched, developed and improved to meet the market demand.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel ventilative, antistatic, antibacterial composite nonwoven to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel ventilative, antistatic, antibacterial composite nonwoven fabric, includes melt-blown nonwoven layer (1), its characterized in that: the upper portion of the melt-blown non-woven fabric layer (1) is provided with a first PP spunbonded non-woven fabric layer (3), the upper portion of the first PP spunbonded non-woven fabric layer (3) is coated with a breathable film (2), the bottom of the melt-blown non-woven fabric layer (1) is provided with a second PP spunbonded non-woven fabric layer (31), and the bottom of the second PP spunbonded non-woven fabric layer (31) is coated with an antibacterial layer (5).
Preferably, a metal mesh layer (7) is arranged between the first PP spunbonded nonwoven fabric layer (3) and the second PP spunbonded nonwoven fabric layer (31).
Preferably, the melt-blown non-woven fabric layer (1) is formed by compounding two melt-blown superfine fiber layers (11, 12).
Preferably, the antibacterial layer (5) is formed by solidifying a fabric antibacterial finishing agent directly sprayed on the bottom of the melt-blown non-woven fabric layer (1).
The utility model has the advantages of air permeability, static electricity prevention, bacteriostasis, etc. The breathable film layer is arranged, so that good breathability is ensured; through being equipped with metal mesh layer, can control electrostatic interference, play the effect of protecting against radiation, through coating antibiotic layer, be favorable to preventing breeding of the inside bacterium of fibre, make people's life convenient and health, be applicable to very much the production of medical clothing cloth.
Drawings
Fig. 1 is a schematic view of the structure of the present invention in partial section.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the utility model provides a novel ventilative, antistatic, antibacterial composite nonwoven fabric: a novel breathable, antistatic and antibacterial composite non-woven fabric comprises a melt-blown non-woven fabric layer 1, wherein the melt-blown non-woven fabric layer 1 is formed by compounding two polypropylene melt-blown superfine fiber layers 11 and 12. The non-woven fabric layer 1 subjected to electret treatment has lasting static electricity and can trap fine dust by virtue of the static effect, so that the non-woven fabric layer has the advantages of high filtering efficiency, low filtering resistance and the like. The polypropylene has high resistivity (7 multiplied by 1010 omega cm) and large capacity of injecting charges, and is an ideal material for manufacturing electret fibers. Experiments show that the filtration efficiency of the electret-finished polypropylene melt-blown non-woven fabric is basically unchanged after the electret-finished polypropylene melt-blown non-woven fabric is stored for 1500 hours in a natural state.
The upper part of the melt-blown non-woven fabric layer 1 is provided with a first PP (polypropylene) spun-bonded non-woven fabric layer 3, the upper part of the first PP spun-bonded non-woven fabric layer 3 is coated with a breathable film 2, and the bottom of the melt-blown non-woven fabric layer 1 is provided with a second PP spun-bonded non-woven fabric layer 31. The extruder die temperature of the first PP spunbond nonwoven layer 3 was set to 221 ℃ -225 ℃.
Preferably, the metal mesh layer 7 is arranged between the first PP spunbonded nonwoven fabric layer 3 and the second PP spunbonded nonwoven fabric layer 31, so that the antistatic property and the radiation intensity can be well reduced.
The bottom of the second PP spunbonded nonwoven 31 is coated with an antibacterial layer 5. The antibacterial layer 5 is formed by solidifying a fabric antibacterial finishing agent directly sprayed on the bottom of the melt-blown non-woven fabric layer 1. The method for treating the fabric by using the fabric antibacterial finishing agent can adopt padding, dipping, spraying and the like, the general dosage is 2-4%, and the specific dosage and the usage are determined according to the application, the type and the composition of a treated object and processing equipment.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
