As can be seen from Table 2, the dye uptake of the linen fabrics obtained in examples 1-3 is greater than 90%, and the dye uptake of the linen fabrics in comparative examples 1-4 is reduced to different degrees compared with the examples, because the linen fabric does not contain chitosan in comparative example 1, the amount of dye molecules adsorbed by linen fibers is lower than that of the examples, the linen fabric does not contain a graphene self-assembly layer in comparative example 2, the adsorption rate of the linen fabric on the dye molecules is reduced, the dye molecules adsorbed by the linen fabric are greatly less than that of the examples in the same dyeing time, and rare earth GdCl is not added in comparative example 33And the combination amount of dye molecules is reduced, and the conventional dyeing process is adopted in the comparative example 4, so that the linen fabric has low dye-uptake due to the existence of impurities in the linen fiber and the characteristics of microstructure.
3 color fastness test
The soaping resistance and the rubbing color fastness are respectively tested according to GB/T3921-2008 'soaping color fastness resistance of textile color fastness test' and GB/T3920-2008 'rubbing color fastness of textile color fastness test' and the results are shown in Table 3.

As can be seen from Table 3, the linen fabrics obtained in examples 1-3 have higher color fastness, and the linen fabrics in comparative examples 1-4 have lower color fastness than the examples, because the linen fabric in comparative example 1 does not contain chitosan, the binding fastness of the linen fiber dye molecules is inferior to that of the examples, the linen fabric in comparative example 2 does not contain the graphene self-assembly layer, the adsorption capacity of the linen fabric on the dye molecules is reduced, and the rare earth GdCl is not added in comparative example 33And the complex effect with dye molecules does not exist, the bonding force with the dye molecules is poor, the conventional dyeing process is adopted in the comparative example 4, and the color fastness of the linen fabric is low due to the existence of impurities in the linen fiber and the characteristics of the microstructure.
4 ultraviolet resistance
The UPF value of the obtained fabric was measured using a textile uv protection tester, each sample was measured 8 times, and the results are averaged and shown in table 4.

Comparative example 1 62 70 37
Comparative example 2 26 86 42
Comparative example 3 55 42 23
Comparative example 4 23 89 30
As can be seen from table 4, the linen fabrics obtained in examples 1 to 3 have better ultraviolet resistance, and the linen fabrics in comparative examples 1, 2 and 4 have different degrees of ultraviolet resistance reduction compared with the examples, because the linen fabrics in comparative example 1 do not contain chitosan, the bonding fastness of the graphene self-assembly layer is inferior to that of the examples, the linen fabrics in comparative example 2 do not contain the graphene self-assembly layer, the ultraviolet absorption capacity is reduced, the linen fabrics in comparative example 4 adopt a conventional dyeing process, the graphene falling possibly caused by the dyeing process can cause the ultraviolet resistance reduction, and the linen fabric in comparative example 3 does not contain rare earth GdCl3And has little influence on the ultraviolet absorption capability.
5 bacteriostatic rate
GB/T20944.3-2008, evaluation of antibacterial performance of textiles part 3: the quantitative test of the bacteriostasis rate is carried out in the oscillation method, a washing method of a washing fastness tester is adopted to test the bacteriostasis rate of the linen fabric after being washed for 5 times, and the test results are shown in the table 5.

Comparative example 2 63.5 34.6
Comparative example 3 99.2 64.7
Comparative example 4 73.9 49.1
As can be seen from table 5, the linen fabrics obtained in examples 1 to 3 have better antibacterial rate and washability, and the ultraviolet resistance of the linen fabrics in comparative examples 1, 2 and 4 are reduced in different degrees compared with the examples, because the comparative example 1 does not contain chitosan, the antibacterial rate is obviously reduced, and the bonding fastness of the graphene self-assembled layer is not as good as the examples, the antibacterial rate is reduced by a larger extent, the comparative example 2 does not contain the graphene self-assembled layer, the antibacterial rate and washability are obviously reduced, the comparative example 4 adopts a conventional dyeing process, the graphene may fall off during the dyeing process, the antibacterial rate is obviously reduced, and the rare earth GdCl is not added in the comparative example 33The effect on the bacteriostatic ability is not great, the bacteriostatic rate is equivalent to that of the example, but the washability is poor due to the lack of complexation, and the washing 1 isThe bacteriostasis rate is reduced by 34.8 percent after 0 time.
In conclusion, the method for dyeing the linen fabric provided by the invention is simple to operate, mild in condition, low in energy consumption, low in pollution, wide in applicable dye range and high in dye uptake, and the obtained linen fabric is bright in color, good in hand feeling, high in strength and color fastness, good in flame retardant property and ultraviolet resistance, and the antibacterial rate is more than 99%.
