Description
Technical field
The invention belongs to technical field of textile manufacture, are related to a kind of textile fabric processing technology with safeguard function,
Especially a kind of antibacterial fabric preparation method based on graphene.
Background technique
As people require increasingly to improve to environmental sanitation, the application of anti-biotic material is by more extensive concern.Bacterium
Breeding can be mushroomed out in suitable environmental conditions, and by spreading the disease with human contact, the body for influencing people is strong.
The textile fabric consisted of fibers, since the chemical structure of its porous type body form and high molecular polymer is conducive to micro- life
Object attachment, becomes the good parasitic body of the microbe survivals such as bacterium, fungi, breeding.The textile that people contact in daily life
It is the ground of the good existence of these microorganisms and the important propagating source of various diseases, so exploitation has the weaving of antibacterial row
Product have extremely important meaning.
Currently, most of the textile with antibacterial functions is to carry out final finishing to textile with antibacterial finishing agent agent, with
Obtain the textile with anti-microbial property.Reason agent is divided into inorganic antibacterial finishing agent, organic anti-bacterial finishing agent after common antibacterial is whole
With natural biological antibacterial finishing agent three categories.Inorganic antiseptic is with inorganic metal class antibacterial agent, photocatalysis antibacterial agent and nanoparticle
Based on sub- antibacterial agent；Organic antibacterial agent is then a kind of the molecule with antibacterial activity to be bonded in one with carrier by covalent bond
It rises, mainly includes quaternary ammonium salt antibacterial agent, quaternary phosphonium salt antibacterial agent, alcohols antibacterial agent, phenolic antiseptic etc.；Natural biological is anti-
Microbial inoculum is the antibacterial agent of the polymer composition with antibacterial functions extracted in natural biological, and there are commonly shells
Glycan, allicin etc..
Graphene oxide (GO) is an important derivative in graphene family, essentially identical with the structure of graphene,
Only there is the oxygen containing functional group such as a large amount of hydroxyl, carboxyl, epoxy group on its surface, these functional groups impart graphite oxide
The many unique properties of alkene, such as good wettability and surface-active, can be with the compatibility of some polymer etc., this can
To assign material more chemical reactivities, adjacent layer can also be made to form network structure raising monolithic interlayer by being crosslinked
Interaction force, so as to improve the physical property of material.With the development of GO functional method, the oxygen-containing collection of different function
Group assigns GO more potential advantage, also starts to increase in the application of antibiosis.
Currently based on graphene antibacterial dacron fabric preparation method there are mainly two types of, one is preparing polyester slice
Stage adds graphene, prepares graphene dacron thread, and one is be organized in by padding method combining graphene on fabric.
It is easy to cause the reunion of graphene in dicing phase addition graphene, and complex process, graphene dispersion uniformity cannot get
Guarantee.It is arranged in the final finishing stage by padding method, the graphene amount for needing to add organic crosslinking agent, and being combined on fabric
Less, binding force is weaker；High-temperature and high pressure dyeing process, in the case where being baked without high temperature, the binding force of graphene and fabric
Weaker, fastness to washing does not reach requirement.

Polyester fabric after dry bakes 3 minutes in 189-191 DEG C, as based on the antibacterial fabric of graphene described in the present embodiment.
Comparative example
A kind of preparation method of Graphene antibiosis fabric, it is substantially same as Example 2, the difference is that: it is dried in drying
After roasting step, also need to carry out antibacterial fabric special reduction treatment, reduction treatment is with sodium hydrosulfite 5g/L, hydrogen specifically
Polyester fabric after the solution of sodium oxide molybdena 1.2g/L bakes drying restores under conditions of 85 DEG C of temperature, the recovery time
30 minutes.
Three, the performance test of embodiment 1-5 and comparative example
1, antibacterial effect
Graphene antibiosis fabric prepared by embodiment 1-5 is according to GB/T 20944.3-2008 " GBT 20944.3-2008
The evaluation third portion of antibacterial textile performance: succusion " standard testing, to staphylococcus aureus, Escherichia coli and white
Candida albicans has excellent antibacterial effect；Bacteriostasis rate is stepped up with the raising of GO content in dye liquor, is up to greater than
99%；The anti-microbial property examining report (the outer detection of committee) of embodiment 4 is shown in Fig. 1.The antibiotic rate of embodiment 1,2,4 and comparative example is real
It tests room detection data and is shown in Table 1.
The polyester fabric bacteriostasis rate of 1 laboratory test various concentration graphene oxide bath foam of table preparation
| Sample ID | 3# (embodiment 4) | 8# (embodiment 2) | 11# (embodiment 1) | B# (comparative example) |
| Bacteriostasis rate | 95.5% | 88.8% | 52.0% | 86.6% |
Remarks: it is 0.25g/L that graphene oxide dispersion concentration is used when in table prepared by sample 3#；
The graphene oxide dispersion concentration that sample 8# is used when preparing is 0.1g/L；
The graphene oxide dispersion concentration that sample 11# is used when preparing is 0.05g/L；
It is 0.10g/L that graphene oxide dispersion concentration is used when prepared by sample B#, by the functional surfaces of reduction after preparation
Material.
As it can be seen from table 1 with the increase for preparing GO concentration in Graphene antibiosis fabric dye liquor, the antibiotic property of fabric
It can be promoted, and can be seen that whether reduction treatment is carried out to fabric after drying bakes from embodiment 2 and comparative example, to fabric
Anti-microbial property influence less, and for embodiment 2 and comparative example, embodiment 2 without reduction treatment fabric it is anti-
Bacterium rate will also rate be higher than comparative example.
2, ultraviolet resistance
Graphene antibiosis fabric prepared by embodiment 1-5 is according to GB/T18830-2009 " ultraviolet resistance of fabric
Evaluation " standard carries out ultraviolet resistance test, the UV protection factor of fabric is greater than 2000.The UV resistance of embodiment 1
Performance detection report is shown in that Fig. 3, the uv resistance energy examining report of embodiment 4 are shown in Fig. 2.Can be seen that according to fig. 2 with Fig. 3 with
The increase of GO concentration in Graphene antibiosis fabric dye liquor is prepared, the ultraviolet resistance of fabric is promoted.
3, moment cool feeling performance
" textile Contact is cool according to GB/T 35263-2017 for Graphene antibiosis fabric prepared by embodiment 1 and 4
It is perceptual can detection and evaluation " standard carries out the detection (examining report of embodiment 1 and embodiment 4 of Contact cool feeling performance
Fig. 3 and Fig. 4 are seen respectively), the Contact cool feeling coefficient of fabric is respectively 0.18 and 0.17, is above technical requirements.As it can be seen that
There is cool feeling by the polyester fabric that the antibacterial fabric preparation method of the present invention based on graphene arranges, the summer can be improved
Season comforts of use.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
