Embodiment 1-5

[0029] Embodiment 1-5 relates 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, apply the coating to the surface of the fabric evenly, and then take it out after drying at 60° for 30 minutes;

[0031] S2. Prepare 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 60 minutes, and dry. The structural representation of the printing pattern of gained graphene antibacterial fabric is as figure 1 shown.

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

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.

Description

technical field [0001] The invention relates to the field of antibacterial coatings, in particular to a graphene antibacterial fabric and a preparation method thereof. Background technique [0002] Antibacterial fabric has good safety, it can effectively and completely remove bacteria, fungus and mildew on the fabric, keep the fabric clean, and prevent bacteria from regenerating and multiplying. [0003] Traditional antibacterial fabrics are finished with antibacterial agents on the surface of the fabric. The disadvantage is that the use of silver ions and other antibacterial agents has been completely banned, while organic antibacterial agents have poor effect, poor fastness, and poor washability. At present, the antibacterial problems on fabrics mainly need to be solved: 1. The antibacterial agents used in fabrics have poor fastness and washability; 2. The problem of poor air permeability of coatings. Therefore, how to obtain a fabric with high antibacterial properties, g...
