Description
Technical Field
The invention belongs to the technical field of spinning, and particularly relates to a preparation method of a cuprous oxide antibacterial textile.
Background
With the improvement of living standard, the health consciousness of people is increased day by day. The porous textile fiber is easy to absorb sweat glands of a human body, and microorganisms are easy to grow and breed under proper temperature and humidity. The presence of microorganisms on textiles not only causes the textiles to mildew, but also can be harmful to the health of the user. Therefore, it is necessary to perform an antibacterial finishing of the fabric.
The antibacterial finishing agent can be divided into an inorganic antibacterial finishing agent, an organic antibacterial finishing agent and a natural antibacterial finishing agent. The inorganic antibacterial finishing agent has broad-spectrum antibacterial property and strong bactericidal capability. Research shows that the nano cuprous oxide can be adsorbed to the cell surface, and the permeability of cell membranes is increased and the viability of bacteria is reduced by destroying cell walls. However, cuprous oxide has poor binding fastness to the textile and the resulting antimicrobial textile is not resistant to washing.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a preparation method of a cuprous oxide antibacterial textile, which comprises the steps of firstly adopting low-temperature plasma to pretreat a cellulose fiber fabric, and then coating a silk peptide solution; and then cuprous oxide is formed in situ on the textile to obtain the antibacterial textile. The obtained fabric has good antibacterial property and is washable.
The invention provides a preparation method of an antibacterial textile, which comprises the following steps:
(1) placing the cellulose fiber fabric on a frame in a cavity of a DT-01 low-temperature plasma treatment instrument produced by Oppu plasma science and technology Limited, Suzhou, starting a vacuum pump, introducing nitrogen into the plasma cavity when the vacuum degree in the reaction cavity is 5Pa, and adjusting the gas flow until the vacuum degree in the reaction cavity is 20-50 Pa; stabilizing glow discharge after 3-5min, and immediately taking out the fabric after the discharge is finished and entering the next operation;
(2) immersing the cellulose fiber fabric treated in the step (1) into a silk peptide solution, treating for a certain time at a certain temperature, drying at 80-85 ℃ after the treatment is finished, then drying at 130-145 ℃ for 3-5min, finally washing for 3-5 times by deionized water, and drying at 60-80 ℃ for later use;
(3) dissolving copper acetate in deionized water to prepare a copper acetate solution, padding the cellulose fiber fabric treated in the step (2) with the copper acetate solution, and padding for two times, wherein the padding allowance is 70-100%; drying at 80-90 deg.C, soaking in dihydric alcohol, reacting at a certain temperature for a certain time, taking out the fabric after the reaction is finished, washing with deionized water for 3-5 times, and drying at 60-80 deg.C.
Wherein, the glow discharge power in the step (1) is 50-150W, and the discharge time is 5-15 min.
Wherein, the silk peptide in the step (2) is commercially available silk peptide powder with the molecular weight of 500-5000, and the silk peptide solution takes deionized water as a solvent, wherein the mass fraction of the silk peptide powder is 1-10%; the silk peptide solution treatment temperature is 30-50 deg.C, and the treatment time is 30-60 min.
Wherein the mass concentration of the copper acetate solution in the step (3) is 10-20 g/L.
Wherein the dihydric alcohol in the step (3) is one of 1, 4-butanediol, 1, 2-propanediol and 1, 3-propanediol, the reaction temperature is 160-180 ℃, and the reaction time is 2-4 h.
The method firstly utilizes low-temperature plasma treatment to introduce amino on the surface of the fabric and simultaneously etches the surface of the cellulose fiber fabric. The silk peptide is silkThe protein degradation product is obtained by hydrolyzing natural silk under proper conditions. The silk peptide has many hydrophilic groups (such as-OH, -COOH, -NH) on its molecular structure2NH-, etc.), and the silk peptide itself has a certain antibacterial property, but the binding fastness with the textile is poor due to its excellent water solubility. There are studies showing that: the copper ions can coordinate with carboxyl and amino on the amino acid to form a coordination polymer. The fabric is treated by silk peptide and then dipped into copper acetate solution, copper ions pass through-COOH and-NH on silk peptide molecules2The coordination forms a coordination polymer, which reduces the water solubility of the silk peptide. And finally, under the reduction action of the dihydric alcohol, copper ions adsorbed on the textile form cuprous oxide in situ, so that the textile is endowed with excellent antibacterial performance.
The invention has the beneficial effects that:
(1) the fabric is pretreated by low-temperature plasma, so that amino groups are introduced to the surface of the fabric while the roughness of the fabric is improved.
(2) The silk peptide with certain antibacterial activity is adopted to pretreat the textile, and the copper ions and the silk peptide molecules form coordination polymers, so that the loading capacity of the copper ions on the textile can be improved, and the binding fastness of the copper ions and the textile can be improved.
(3) And the in-situ generation of cuprous oxide is realized by using dihydric alcohol as a solvent and a reducing agent.

Example 5
20944.2-2007 evaluation of antibacterial Properties of textiles part 2: absorption method determines the antibacterial properties of finished fabrics. antibacterial property test: according to GB/T
Antibacterial effect wash resistance test: the fabric antibacterial effect water washing resistance test is carried out according to the test condition A1M in GB/T12490-. And after the specified washing times are reached, fully washing the sample by using water, and airing.
The antibacterial property test results of the fabric are as follows:
TABLE 1 antibacterial Properties of the fabrics
As can be seen from Table 1, the fabrics obtained in examples 1-4 have excellent antibacterial properties against Escherichia coli, Staphylococcus aureus, Bacillus subtilis, and the finished fabric has excellent wash fastness. In comparative example 1-1, the amount of silk peptide coated on the fabric without low temperature plasma treatment was small and the amount of cuprous oxide finally attached to the fabric was small, and thus the antibacterial activity of the resulting fabric was inferior, and the fabric also had good washing fastness because the silk peptide and cuprous oxide formed a coordination polymer on the fabric, and the cuprous oxide and silk peptide eluted from the fabric during washing were mechanically hindered more. In comparative examples 1-2, the fabric was not treated with silk peptide, which resulted in a decrease in the amount of copper ions adsorbed on the fabric, a decrease in the amount of cuprous oxide generated in situ, and no synergistic antibacterial effect of silk peptide, and thus, the antibacterial activity of the finished fabric was poor. Because no coordination between copper ions and silk peptide exists, the generated cuprous oxide is only attached by machinery, and therefore, the obtained fabric has poor antibacterial effect and poor water washing resistance. In comparative examples 1 to 3, since the fabric was not treated with cuprous oxide, the antibacterial property of the fabric was provided only by the silk peptide, and since the silk peptide had excellent water solubility, the obtained fabric was inferior in both antibacterial property and antibacterial effect and water-washing resistance. In comparative examples 1 to 4, since pentanediol is poor in reducibility and copper ions cannot be reduced to cuprous oxide, the antibacterial performance of the obtained fabric is mainly provided by silk peptide, and since a small amount of copper ions are adsorbed on the fabric, the antibacterial performance of the obtained fabric is superior to that of comparative examples 1 to 3.
