Abstract

The invention provides a preparation method of a graphene antibacterial fabric. The method comprises the following steps that S1, an antibacterial agent and a binder are uniformly mixed and then applied to the surface of a fabric, and then drying is conducted; S2, the dried fabric is put into a mixed solution of a reducing agent and deionized water, and then the fabric is taken out and dried, wherein the antibacterial agent is one or multiple of graphene, graphene oxide and amino-modified graphene. Accordingly, a novel graphene antibacterial raw material is combined with bonding and chemical bonding modes to achieve the antibacterial function on a single layer fabric, not only are the antibacterial property and the washing fastness of the fabric ensured, but also the antibacterial water washing resistance of the fabric is improved.

Example Embodiment

[0028] Examples 1-5

[0029] Embodiment 1-5 relate to a kind of preparation method of graphene antibacterial fabric respectively, and concrete operation steps are as follows:

[0030] S1. Mix the antibacterial agent and the adhesive according to the mass fraction in Table 1. After mixing evenly, evenly coat the fabric surface by means of coating, and take it out after drying at 60° for 30min;

[0031] S2, configure the reducing agent solution according to the type and mass fraction in Table 1, put the dried cloth into the reducing agent at 80° for water bath reduction for 60min, and dry. The structural schematic diagram of the printed pattern of the obtained graphene antibacterial fabric is as follows figure 1 shown.

[0032] The types and contents of raw materials involved in Examples 1-5 are shown in Table 1 below:

[0033] Table 1

[0034]

[0035] In the above table 1, the preparation steps of monoquaternary ammonium salt modified graphene and double quaternary ammonium salt modified graphene are: by graphene oxide and quaternary ammonium salt 336 or dimethyl dioctadecyl ammonium chloride by 0.05 Mixing in a ratio of 1-2°C/min, heated to 90°C-100°C in a 1-2°C/min water bath, and then kept at a constant temperature for 60-90min to obtain mono-quaternary ammonium salt-modified graphene and double-quaternary ammonium salt-modified graphene, respectively.

Example Embodiment

[0036] Example 6

[0037] The present embodiment provides a preparation method of graphene antibacterial fabric, and the specific operation steps are basically the same as those in embodiment 2, except that: in this comparative example, polyquaternium-11 is used to modify graphene oxide to Preparation of amino-modified graphene.
