Description
Technical Field
The invention belongs to the technical field of textile manufacturing, relates to a textile fabric processing technology with a protection function, and particularly relates to a preparation method of an antibacterial fabric based on graphene.
Background
With the increasing demand of people on environmental sanitation, the application of antibacterial materials is concerned more widely. Bacteria can rapidly grow and reproduce under proper environmental conditions, and diseases are transmitted through contact with human bodies, so that the health of people is influenced. The textile fabric composed of the fibers is favorable for the attachment of microorganisms due to the porous object shape and the chemical structure of the high molecular polymer, and becomes a good parasite for the survival and propagation of the microorganisms such as bacteria, fungi and the like. Textiles that come into contact with people in daily life are the place where these microorganisms live well and are also important sources of transmission of various diseases, so the development of textiles with antibacterial properties is of great importance.
At present, most of textiles with antibacterial function are subjected to after-treatment by using an antibacterial finishing agent to obtain the textiles with antibacterial property. Common antibacterial finishing agents are classified into three major classes, namely inorganic antibacterial finishing agents, organic antibacterial finishing agents and natural biological antibacterial finishing agents. The inorganic antibacterial agent mainly comprises an inorganic metal antibacterial agent, a photocatalytic antibacterial agent and a nano-particle antibacterial agent; the organic antibacterial agent is a compound which bonds molecules with antibacterial activity with a carrier through covalent bonds, and mainly comprises a quaternary ammonium salt antibacterial agent, a quaternary phosphonium salt antibacterial agent, an alcohol antibacterial agent, a phenol antibacterial agent and the like; the natural biological antibacterial agent is an antibacterial agent composed of organic high molecular substances extracted from natural organisms and having antibacterial function, and commonly used chitosan, garlicin and the like.
Graphene Oxide (GO) is an important derivative in graphene family, has basically the same structure as graphene, and only has a large number of oxygen-containing functional groups such as hydroxyl, carboxyl, epoxy and the like on the surface, and the functional groups endow the graphene oxide with a plurality of unique properties such as good wetting property and surface activity, compatibility with some polymers and the like, so that the graphene oxide can endow materials with more chemical reaction performance, and can also form a network structure by crosslinking to improve the interaction force between single sheets, thereby improving the physical properties of the materials. With the development of GO functionalization methods, oxygen-containing groups with different functions offer more potential advantages to GO, and the application of GO in the aspect of antibiosis is also increased.
At present, two preparation methods of the graphene-based antibacterial polyester fabric are mainly used, one is to add graphene in the stage of preparing polyester chips to prepare graphene polyester yarns, and the other is to combine graphene on the fabric by finishing through a padding method. The addition of graphene at the slicing stage easily causes the agglomeration of graphene, the process is complex, and the dispersion uniformity of the graphene cannot be guaranteed. In the post-finishing stage, finishing is performed through a padding method, an organic cross-linking agent needs to be added, the amount of graphene combined on the fabric is small, and the binding force is weak; according to the high-temperature high-pressure dyeing method, under the condition that high-temperature baking is not carried out, the binding force between graphene and the fabric is weak, and the washing fastness cannot meet the requirement.

The graphene antibacterial fabric prepared in examples 1 to 5 is evaluated according to the evaluation part 3 of GB/T20944.3-2008 GBT20944.3-2008 textile antibacterial performance: the standard test of the oscillatory method shows that the antibacterial agent has excellent antibacterial effect on staphylococcus aureus, escherichia coli and candida albicans; the bacteriostasis rate gradually increases along with the increase of the GO content in the dye liquor, and the highest bacteriostasis rate is more than 99 percent; the antimicrobial performance test report (ex-commission test) of example 4 is shown in fig. 1. The laboratory test data for the antibacterial ratio of examples 1, 2, 4 and comparative example are shown in table 1.
Table 1 laboratory test of bacteriostasis rate of polyester fabric prepared from graphene oxide bath solution with different concentrations
| Sample name | 3# (embodiment 4) | 8# (embodiment 2) | 11# (embodiment 1) | B # (comparative example) |
| Rate of inhibition of bacteria | 95.5％ | 88.8％ | 52.0％ | 86.6％ |
Remarking: in the table, the concentration of the graphene oxide dispersion used in the preparation of sample No. 3 is 0.25 g/L;
the concentration of the graphene oxide dispersion used in the preparation of sample No. 8 was 0.1 g/L;
the concentration of the graphene oxide dispersion used in the preparation of sample No. 11 was 0.05 g/L;
the graphene oxide dispersion solution with the concentration of 0.10g/L is used for preparing the sample B #, and the prepared functional fabric is reduced.
From table 1, it can be seen that the antibacterial performance of the fabric is improved with the increase of GO concentration in the dye liquor for preparing the graphene antibacterial fabric, and from example 2 and the comparative example, it can be seen that whether the fabric is subjected to reduction treatment after drying and baking has little influence on the antibacterial performance of the fabric, and in terms of example 2 and the comparative example, the antibacterial rate of the fabric which is not subjected to reduction treatment in example 2 is higher than that of the comparative example.
2. Ultraviolet ray resistance
The graphene antibacterial fabric prepared in the embodiments 1-5 is subjected to ultraviolet resistance performance test according to the GB/T18830-2009 evaluation on ultraviolet resistance performance of textiles, and the ultraviolet protection coefficient of the fabric is larger than 2000. The report of the test of the ultraviolet resistance of the example 1 is shown in fig. 3, and the report of the test of the ultraviolet resistance of the example 4 is shown in fig. 2. According to the graph 2 and the graph 3, the ultraviolet resistance of the fabric is improved along with the increase of the GO concentration in the dye liquor for preparing the graphene antibacterial fabric.
3. Instant cool feeling performance
The graphene antibacterial fabrics prepared in the embodiments 1 and 4 are subjected to detection of the contact instant cooling performance according to the standard of GB/T35263 plus 2017 detection and evaluation of textile contact instant cooling performance (the detection reports of the embodiments 1 and 4 are respectively shown in FIGS. 3 and 4), and the contact instant cooling coefficients of the fabrics are respectively 0.18 and 0.17, which are higher than the technical requirements. Therefore, the polyester fabric finished by the preparation method of the graphene-based antibacterial fabric has cool feeling, and the comfort level in summer can be improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
