And secondly, adding the copper ammonia spinning solution into a second stirring container, adding the additive solution prepared in the step one, uniformly stirring (the rotating speed is between 75rpm and 150 rpm) to obtain a spinning solution, and spinning the uniformly stirred spinning solution.
The invention also relates to a preparation method of the bacteriostatic copper ammonia fabric, which comprises a spinning preparation process, wherein the spinning solution adopted in the spinning preparation process is the spinning solution.
The invention also relates to an antibacterial copper ammonia fabric which is prepared by the preparation method.
Graphene bacteriostasis principle: the graphite with 1 mm contains 300 ten thousand layers of single-layer graphene, the smallest bacterium is 0.2 mm which is about 600 times of graphene, and the bacterium can be cut through cell walls to die when walking on the sharp nanoscale two-dimensional material. The graphene bacteriostatic application can cut the bacterial cell membrane by inserting the bacterial cell membrane, and can destroy the cell membrane by directly extracting phospholipid molecules on the bacterial cell membrane in a large scale so as to kill bacteria, thereby further enhancing the bactericidal capacity and achieving an excellent antibacterial effect.
The 1, 3-propylene glycol is mainly used for improving the hand feeling, but in the technical development of the invention, the addition of the 1, 3-propylene glycol can not only improve the softness of the fabric, but also obviously improve the breaking strength of the fabric within a certain dosage range, and can prepare the high-strength cuprammonium fabric.
The present invention will be described in further detail with reference to specific examples and comparative examples.
Example 1:
graphene fluffy powder (accounting for 0.015% of the mass of the spinning solution), 1, 3-propylene glycol (accounting for 6% of the mass of the spinning solution), and a cuprammonium spinning solution (accounting for 93.985% of the mass of the spinning solution);
the bacteriostatic high-strength copper ammonia fabric (86) is provided.5g/m2) The bacteriostatic, breaking strength and softness (total average bending length, lower and softer) effects are shown in the table below

The antibacterial high-strength copper ammonia fabric prepared in the embodiment has higher breaking strength, better softness than that of a common copper ammonia fabric, excellent antibacterial performance, excellent antibacterial effect after being washed by water for many times, and no obvious reduction of breaking strength. The reason is that the fixation fastness of the copper ammonia fiber prepared by dispersing the graphene with the bacteriostatic action in the spinning solution is excellent. 1, 3-propanediol is used as another main component in the spinning solution, the strength of the fabric is greatly improved due to the inherent characteristics and hydrogen bond crosslinking with cuprammonium molecules, but the influence of the formed crosslinking structure on the stiffness of the fabric is very small due to the relatively small molecules, so that the softness of the fabric is excellent.
Example 2:
graphene fluffy powder (accounting for 0.025 percent of the mass of the spinning solution), 1, 3-propylene glycol (accounting for 12 percent of the mass of the spinning solution), and cuprammonium spinning solution (accounting for 87.975 percent of the mass of the spinning solution);
the bacteriostatic high-strength cuprammonium fabric of the embodiment (87.4 g/m)2) The bacteriostatic, breaking strength and softness (total average bending length, lower and softer) effects are shown in the table below
Table 2 example 2 bacteriostatic high-strength cuprammonium fabric performance test
The antibacterial high-strength copper ammonia fabric prepared in the embodiment has higher breaking strength, better softness than that of a common copper ammonia fabric, excellent antibacterial performance, excellent antibacterial effect after being washed by water for many times, and no obvious reduction of breaking strength. The usage amount of the graphene fluffy powder accounting for 0.025% of the mass of the spinning solution is higher than that of example 1, the antibacterial effect is slightly better than that of example 1, but is not obvious, the usage amount of the 1, 3-propylene glycol is higher than that of example 1, the softness is not greatly influenced, and the breaking strength of the fabric is improved to a certain extent.
Example 3:
graphene fluffy powder (accounting for 0.032 mass of the spinning solution), 1, 3-propylene glycol (accounting for 18 mass of the spinning solution), and cuprammonium spinning solution (accounting for 81.968 mass percent of the spinning solution);
the bacteriostatic high-strength cuprammonium fabric of the embodiment (87.9 g/m)2) The bacteriostatic, breaking strength and softness (total average bending length, lower and softer) effects are shown in the table below
Table 3 example 3 bacteriostatic high strength cuprammonium fabric performance test
The antibacterial high-strength copper ammonia fabric prepared in the embodiment has higher breaking strength, better softness than that of a common copper ammonia fabric, excellent antibacterial performance, excellent antibacterial effect after being washed by water for many times, and no obvious reduction of breaking strength. The usage amount of the graphene fluffy powder accounting for 0.032% of the mass of the spinning solution is higher than that of example 1, the antibacterial effect is slightly better than that of example 1, but is not obvious, the usage amount of the 1, 3-propylene glycol is higher than that of example 1, the influence on softness is little, and the breaking strength of the fabric is improved to a certain extent.
Example 4:
graphene fluffy powder (accounting for 0.012 mass of the spinning solution), 1, 3-propylene glycol (accounting for 12 mass of the spinning solution), and a cuprammonium spinning solution (accounting for 87.988 mass percent of the spinning solution);
the bacteriostatic high-strength cuprammonium fabric of the embodiment (86.9 g/m)2) The bacteriostatic, breaking strength and softness (total average bending length, lower and softer) effects are shown in the table below
Table 4 example 4 bacteriostatic high strength cuprammonium fabric performance test
In the embodiment, the dosage of graphene fluffy powder accounting for 0.012 percent of the mass of the spinning solution is lower than that in the embodiment 1, the antibacterial effect is obviously lower than that in the embodiments 1-3, 1, 3-propylene glycol and the embodiment 2, the softness is better, the breaking strength of the fabric is similar to that in the embodiment 2, and the increase of the dosage of the 1, 3-propylene glycol in a certain range is proved to improve the breaking strength of the fabric to a certain extent. The antibacterial performance of the graphene fluffy powder is obviously reduced when the content of the graphene fluffy powder is lower than 0.015% of that of example 1, so that the antibacterial effect can be ensured only by adding 0.015% of the graphene fluffy powder.
Example 5:
graphene fluffy powder (accounting for 0.024 mass percent of the spinning solution), 1, 3-propylene glycol (accounting for 5 mass percent of the spinning solution), and cuprammonium spinning solution (accounting for 84.976 mass percent of the spinning solution);
the bacteriostatic high-strength cuprammonium fabric of the embodiment (86.9 g/m)2) The bacteriostatic, breaking strength and softness (total average bending length, lower and softer) effects are shown in the table below
Table 5 example 5 performance test of bacteriostatic high-strength cuprammonium fabric
In the embodiment, the graphene fluffy powder accounts for 0.024% of the mass of the spinning solution, and has good antibacterial performance, but when the 1, 3-propylene glycol accounts for 5% of the mass of the spinning solution, the breaking strength and softness are obviously reduced, so that at least 6% of the graphene fluffy powder is added to ensure good breaking strength and softness.
Example 6:
graphene fluffy powder (accounting for 0.040% of the mass of the spinning solution), 1, 3-propylene glycol (accounting for 5% of the mass of the spinning solution), and cuprammonium spinning solution (accounting for 84.976% of the mass of the spinning solution);
the bacteriostatic high-strength cuprammonium fabric of the embodiment (87.9 g/m)2) Bacteriostasis, breaking strength and softness (total average bending length, lower and lower)Soft) effect as shown in the following table
Table 6 example 6 bacteriostatic high strength cuprammonium fabric performance test
The graphene fluffy powder accounts for 0.040% of the mass of the spinning solution in the example, and the breaking strength of the fabric is obviously reduced due to the increase of the graphene consumption, the bending length is higher than that of the fabric in the example 1, and the softness of the fabric is also reduced. The antibacterial performance is not obviously changed due to the increase of the using amount of the graphene, so that the graphene fluffy powder accounts for 0.015-0.032% of the mass of the spinning solution better.
Example 7:
graphene fluffy powder (accounting for 0.032 mass of the spinning solution), 1, 3-propylene glycol (accounting for 19 mass of the spinning solution), and cuprammonium spinning solution (accounting for 80.968 mass percent of the spinning solution);
the bacteriostatic high-strength cuprammonium fabric of the embodiment (87.9 g/m)2) The bacteriostatic, breaking strength and softness (total average bending length, lower and softer) effects are shown in the table below
Table 7 example 7 bacteriostatic high strength cuprammonium fabric performance test
In the example, 1, 3-propylene glycol (accounting for 19% of the mass of the spinning solution) is better than the common cuprammonium fabric in softness, but the breaking strength is obviously reduced, which shows that the breaking strength of the fabric is reduced due to excessive use amount. Due to the addition of the graphene, the antibacterial performance of the fabric is excellent, the fabric still has excellent antibacterial effect after being washed for many times, and the breaking strength is not obviously reduced.
Comparative example 1
1, 3-propylene glycol (accounting for 6% of the mass of the spinning solution) and a cuprammonium spinning solution (accounting for 94% of the mass of the spinning solution);
the cuprammonium fabric of this example (86.5 g/m)2) Bacteriostasis, breaking strength and softness (total average bending length, lower and softer) The effects are as follows
Table 8 comparative example 1 bacteriostatic high-strength cuprammonium fabric performance test
In the example, graphene fluffy powder is not added, only 1, 3-propylene glycol (accounting for 6% of the spinning solution) is added, and the breaking strength of the obtained copper ammonia fabric is slightly improved, but no bacteriostatic performance is provided, which indicates that the graphene mainly plays a role in bacteriostasis.
Comparative example 2
Graphene fluffy powder (accounting for 0.015 wt% of the spinning solution), and a cuprammonium spinning solution (accounting for 99.985 wt% of the spinning solution);
the cuprammonium fabric of this example (86.5 g/m)2) The bacteriostatic, breaking strength and softness (total average bending length, lower and softer) effects are shown in the table below
TABLE 9 COMPARATIVE EXAMPLE 2 PERFORMANCE TEST OF BACTERIAL HIGH-STRENGTH COPPER AMMONIA FABRIC
In the example, the performance test effect of the spinning solution without adding 1, 3-propylene glycol (accounting for 6% of the mass of the spinning solution) is that the breaking strength is obviously not high, and the breaking strength is close to that of a common cuprammonium fabric, and the softness is close to that of the common cuprammonium fabric. The antibacterial performance is greatly improved, which shows that the graphene fluffy powder has a good antibacterial effect under the dosage.
Comparative example 3:
graphene fluffy powder (accounting for 0.012 mass of the spinning solution), and a cuprammonium spinning solution (accounting for 99.988 mass of the spinning solution);
copper ammonia fabric of this example (87.2 g/m)2) The bacteriostatic, breaking strength and softness (total average bending length, lower and softer) effects are shown in the table below
TABLE 10 COMPARATIVE EXAMPLE 3 PERFORMANCE TEST OF BACTERIAL HIGH-STRENGTH COPPER AMMONIA FABRIC
The sample has no performance test effect of 1, 3-propylene glycol, the breaking strength and the softness of the sample are close to those of a common cuprammonium fabric, and the antibacterial performance is not ideal and is only about 88% because graphene fluffy powder (accounting for 0.012% of the mass of the spinning solution) is less than 0.015%.
Comparative example 4:
1, 3-propylene glycol (accounting for 19% of the mass of the spinning solution) and a cuprammonium spinning solution (accounting for 81% of the mass of the spinning solution);
the cuprammonium fabric of this example (86.9 g/m)2) The bacteriostatic, breaking strength and softness (total average bending length, lower and softer) effects are shown in the table below
Table 4 comparative example 4 bacteriostatic high-strength cuprammonium fabric performance test
In the example, 1, 3-propylene glycol (accounting for 19% of the mass of the spinning solution) is more than 18% of the dosage range protected by the invention, and data show that the breaking strength of the fabric is obviously reduced, and the fabric does not have antibacterial performance because graphene is not added, so that the dosage of 1, 3-propylene glycol accounts for 6% -18% of the mass of the spinning solution better.
