However, the existing antibacterial cloth generally has the defects of poor antibacterial effect, easy shedding of antibacterial substances, influence on service life and the like. Through a great deal of research, the applicant finds that the reasons are mainly the method problem of the antibacterial cloth in the manufacturing process and the problem of the treatment of the manufactured cloth, so that the existing antibacterial cloth has poor effect.
For example, chinese patent CN202010944701.6 discloses a method for preparing an antibacterial fabric and an antibacterial fabric, in which the antibacterial fabric is prepared by directly soaking the antibacterial agent in the antibacterial agent and then making the fabric, which is easy to cause the antibacterial agent to fall off. The invention adopts a new treatment method, and can effectively overcome the problem that the antibacterial agent is easy to fall off.
Disclosure of Invention
The invention overcomes the defects and provides the antibacterial cloth and the manufacturing process thereof, and the antibacterial cloth has the efficient and lasting antibacterial effect.
The technical scheme of the invention is as follows.
A manufacturing process of antibacterial cloth comprises the following steps:
(1) olefin treatment of organic antibacterial agent: taking an organic antibacterial agent (5-methyl-2-isopropylphenol) to react for 6-7h at the temperature of 500 ℃ and 700 ℃ in the presence of a catalyst to obtain a treated organic antibacterial agent;
(2) adding the organic antibacterial agent obtained in the step (1) and butadiene into a reaction kettle according to the mass ratio of 1-2: 1, adding a catalyst, and reacting at 100-150 ℃ for 5-6h to obtain a master batch A containing the antibacterial agent;
(3) adding the organic antibacterial agent obtained in the step (1) and styrene in a ratio of 1-2: 1 into a reaction kettle, adding a catalyst, and reacting at 100-150 ℃ for 4-7h to obtain a master batch B containing the antibacterial agent;
(4) heating and melting the antibacterial agent-containing base particle A, the antibacterial agent-containing master particle B, the polyhexamethylene guanidine and the n-butyl alcohol obtained in the step (2), and preparing the antibacterial cloth by adopting an electrostatic spinning method;
(5) and (4) carrying out hydrophobic treatment on the antibacterial cloth obtained in the step (3).
In the invention, in the step (1), the catalyst is ferric oxide.
In the present invention, in the step (2) and the step (3), the catalyst is hydrogen peroxide.
In the invention, in the step (3), the addition amount of the antibacterial agent-containing base particle A, the antibacterial agent-containing master particle B, the polyhexamethylene guanidine and the n-butyl alcohol satisfies the mass ratio of 1-2: 3: 2-3: 5.
in the invention, in the step (4), the electrostatic spinning parameter is 8-50 kV.
In the invention, in the step (4), the inner diameter of the electrostatic spinning spinneret is 0.2-1 m.
In the invention, in the step (4), the flow rate of the solution is 5-50 ml/h, the temperature of the molten master batch slurry in the electrostatic spinning nozzle is 120-150 ℃, and the distance between the electrostatic spinning nozzle and the receiving device is controlled to be 15-30 cm.

Figure BDA0003146803990000033
the polymerization degree of all polymers is 100000-500000. In the application, the antibacterial cloth is prepared by adopting two master batches, fusing and then combining the antibacterial agent and adopting an electrostatic spinning method. The master batch prepared from the treated organic antibacterial agent prepared in the step (1) in the application can enable the final antibacterial cloth to have a long-term antibacterial effect, and the antibacterial performance of the product can be obviously improved by the polyhexamethylene guanidine added in the step (4). In addition, the applicant finds out through a large amount of research that the antibacterial cloth is subjected to hydrophobic treatment, so that the antibacterial effect can be further improved, and bacteria are not easy to breed in application. The product of the invention can be loaded on other cloth.
The product of the invention can be applied to medical bedsheets, surgical drapes and surgical table cloths.
In the invention, the adopted electrostatic spinning method is to carry 8-50 kV high-voltage static electricity, and charged polymer liquid drops are accelerated at the Taylor cone vertex of the capillary under the action of an electric field force. The polymer droplets overcome surface tension to form a jet stream. The solvent is evaporated or solidified in the fine flow in the spraying process, and finally the fine flow falls on a receiving device to obtain the antibacterial cloth.
Compared with the prior art, the invention has the advantages that:
according to the invention, the antibacterial agent raw material is modified and then polymerized with butadiene or styrene, so that the antibacterial agent is bonded in the master batch, and the antibacterial cloth prepared by a subsequent method has a long-term antibacterial effect.
