Problems solved by technology

[0004] However, due to the graphene fabric prepared by the padding method, the graphene is concentrated on the surface of the fabric, and it is easy to cause wear or fall off of the graphene during use, so its service life is short

Embodiment 1

[0038] Embodiment 1: a kind of antibacterial fabric based on graphene, as attached figure 1As shown, it includes fabric layer 1, adhesive layer 2, graphene layer 3 and protective layer 4 sequentially from inside to outside;

[0039] The fabric layer 1 is woven from cotton fibers; the adhesive layer 2 is a structural layer formed after finishing the surface of the fabric layer with polyethyleneimine; the graphene layer 3 is graphene oxide on the surface of the adhesive layer The main antibacterial structural layer formed after hot pressing; protective layer 4 is the main protective structural layer formed by the cross-linking of epoxy resin glue on the surface of the bonding layer, and the epoxy resin glue is mainly composed of epoxy resin , Polyetheramine and benzyl alcohol mixed.

[0040] The production process is:

[0041] S1: use cotton fibers as warp and weft threads to weave to form a fabric layer to obtain a base fabric, the ratio of the warp density to the weft densit...

Embodiment 2

[0045] Embodiment 2: A graphene-based antibacterial fabric. The difference from Embodiment 1 is that various parameters in the process are different, as shown in Table 1 below.

[0046] The production process is:

[0047] S1: use cotton fibers as warp and weft threads to weave to form a fabric layer to obtain a base fabric, the ratio of the warp density to the weft density of the base fabric is 2:1, and the count of the cotton fibers used is 42s / 3;

[0048] S2: Soak the base fabric in a polyethyleneimine solution with a concentration of 3.5g / L and an average molecular weight of 2500 for 2.5 hours to form an adhesive layer. In the graphene oxide solution, stand at 35°C for 35 minutes to form a graphene layer, take it out, wash it with deionized water and dry it to get a graphene fabric;

[0049] S3: Mix epoxy resin, polyether amine and benzyl alcohol according to the amount to obtain epoxy resin glue. The mass fraction of each component is shown in Table 1. The epoxy value of ...

Embodiment 3-4

[0051] Embodiment 3-4: a kind of antibacterial fabric based on graphene,

[0052] The difference from Example 1 is that the epoxy value of the epoxy resin used is different, and the specific parameters are shown in Table 1 below.

Abstract

The invention relates to the field of fabrics, and particularly discloses a graphene-based antibacterial fabric and a production process thereof. The fabric sequentially comprises a fabric layer, a bonding layer, a graphene layer and a protective layer from inside to outside; the fabric layer is formed by tatting cotton fibers; the bonding layer is a structural layer which is formed after the surface of the fabric layer is finished by polyethyleneimine and plays a role in bonding transition; the graphene layer is a structural layer which is formed by hot-press finishing of graphene oxide on the surface of the bonding layer and plays a main antibacterial role; the protective layer is a structural layer which is formed by crosslinking epoxy resin glue on the surface of the bonding layer and mainly has a protective effect; and the epoxy resin glue is mainly formed by mixing epoxy resin, polyether amine and benzyl alcohol. The graphene antibacterial fabric prepared by the process has good wear resistance on the surface and can be used for a long time, and the graphene layer is not easy to wear or not prone to falling off, so that the graphene antibacterial fabric has more durable antibacterial performance.

Description

technical field [0001] This application relates to the technical field of fabrics, in particular to a graphene-based antibacterial fabric and its production process. Background technique [0002] As a functional fabric, antibacterial fabric has gradually entered people's lives and has been widely used. There are many types of antibacterial fabrics, such as traditional kapok fiber fabrics, chitosan fiber fabrics, hemp fiber fabrics, etc. In recent years, with the development of graphene materials, various unique effects have been gradually applied to different fabrics. Graphene antibacterial fabric is a new type of fabric made by applying the antibacterial ability of graphene. [0003] Graphene fabrics are usually prepared in two ways. The first is to melt and blend the sliced ​​raw materials with graphene in the spinning stage to obtain graphene-containing fibers and then weave them into fabrics; the second is to fabricate fabrics After the textile is formed, it is finishe...
