[0098] (3) After the constant temperature stirring is completed, the temperature of the reaction solution is slowly adjusted to 10° C., 20 g of 25% glutaraldehyde aqueous solution is added to each 1 L of the reaction solution for cross-linking and curing, and the pH value is adjusted to 9.0. After stirring, the solution is allowed to stand until the microcapsules are completely precipitated, filtered, washed with deionized water until neutral, filtered and vacuum dried to obtain the microcapsule product.

[0112] (Note: The mass fraction of the core material and wall material is the mass fraction of the reaction solution)

[0113] The performance of the plant antibacterial health care fabrics containing fruit vitamins prepared in Examples 1 to 5 and Comparative Examples 1 to 3 was tested, and the testing method was as follows:

[0114] (1) The test method for the antibacterial performance of health care fabrics is as follows: refer to "GB / T 20944.2-2007 Evaluation of antibacterial properties of textiles Part 3 Oscillation method" to quantitatively test the antibacterial properties of fabrics.

[0115] (2) The test method for vitamin E content in health care fabrics is as follows: Referring to GB 5009.82-2016 National Food Safety Standard Determination of Vitamins A, D and E in Foods, the vitamin E in the sample is extracted and concentrated with an organic solvent, separated using a high performance liquid chromatography amide column or a silica gel column, detected using a fluorescence detector, and quantified using the external standard method.

[0116] (3) The test method for the moisture absorption performance of health care fabrics is as follows: refer to "GB / T 21655.1-2008 Evaluation of moisture absorption and quick-drying properties of textiles Part 1: One-way combined test method" to test the moisture absorption of fabrics. The water absorption rate and droplet diffusion time are used to characterize the fabric's ability to absorb liquid sweat; the water evaporation rate and moisture permeability are used to characterize the fabric's ability to retain moisture.

[0117] (4) The test method for the negative oxygen ion generation of health care fabrics is as follows: Referring to "GB / T 30128-2013 Test and Evaluation of Negative Ion Generation of Textiles", the fabric sample is installed on the upper and lower friction disks in a test chamber of a certain volume, and rubbed under specified conditions. An air ion meter is used to test the number of negative ions generated per unit volume when the fabric samples rub against each other.

[0118] (5) With reference to GB / T 18830-2009 Evaluation of UV protection performance of textiles, the UV protection performance of fabrics was tested using UV-2000 fabric sun protection index analyzer, which was characterized by the UPF value. The test specimens were kept dry and relaxed, the test light source was the solar luminescence spectrum EN 13758, the temperature was (20±2)℃, and the humidity was (65±2)%.

[0119] After testing, the experimental data obtained are shown in Tables 1 to 6.

[0134]

[0135] After testing, the antibacterial rate of the fabric against three bacteria is shown in Table 2, and the antibacterial rate of the fabric after washing is shown in Table 3. The prepared fabric has antibacterial properties against Staphylococcus aureus, Escherichia coli, and Candida albicans, and the antibacterial property can reach more than 96%. The fabric was washed and tested. It can be seen from Table 2 that the antibacterial effect can reach about 70% after washing 15 times, and it still has a good antibacterial effect. After washing 20 times, the antibacterial effect can still reach more than 60%.

[0136] As can be seen from Table 4, there is abundant vitamin E in the fabric, which means that the fruit vitamin E crude oil added in the preparation of the core material can be well preserved in the fabric microcapsules, making the fabric have skin-friendly, moisture-absorbing, anti-oxidation and other care functions.

[0137] It can be seen from Table 5 that the care fabrics prepared by the present invention have excellent hygroscopicity and good water retention capacity, and the care fabric prepared in Example 1 has a higher water absorption rate of 344%, a lower evaporation rate, and has a better water storage capacity.

[0138] Table 6 shows that the fabric has the function of negative ion emission. The plant antibacterial health care fabric containing fruit vitamins continuously releases plant essential oils with negative ion release function when in contact with air, water vapor and other media. When water molecules in the air, other molecules or moisture on the surface of the skin enter the negative ion electric field space (generally spherical with a radius of 10 to 15 μm), they are immediately ionized by the permanent electrode to produce OH - and H + . Due to H + Move very fast (H + The moving speed is OH - 1 to 8 times of the original mass), quickly moves to the negative electrode of the permanent electrode, absorbs an electron and becomes H2, which escapes into the air, while OH - It forms H3O2 with other water molecules - Negative ions. This change will continue as long as the air humidity is not zero, and will not produce toxic substances to cause other side effects. That is, it has health functions such as purifying the air, improving sleep and regulating blood pressure.

[0139] As shown in Table 7, the care fabrics prepared in Examples 1 to 5 all meet the national standards for UV protection, and the plant antibacterial health care fabrics containing fruit vitamins continuously release plant essential oils and fruit vitamins with UV protection when in contact with air, water vapor and other media. This fabric has a certain UV protection function.

[0140] In summary, the preparation methods of the present invention can obtain fruit vitamin fabrics with antibacterial health care effects, and the preparation process is repeatedly tested to obtain the optimal core-to-wall ratio of 3, the reaction temperature of 55°C, and the reaction time of 20 min.

[0141] The present invention microencapsulates the compound vitamin plant essential oil so that the vitamins and plant essential oil components are retained to the maximum extent. The prepared microcapsules have high embedding rate, low water content, good solubility and lasting fragrance retention. The microcapsules are then processed onto textiles or non-woven fabrics through a padding process to finally produce a new type of plant antibacterial health care fabric containing fruit vitamins that has the characteristics of antibacterial, UV protection, moisture absorption and skin moisturizing, and releasing negative oxygen ions.

[0142] The preparation method of the present invention can obtain fruit vitamin fabrics with antibacterial health care effects, and the preparation process is repeatedly tested to obtain the best core-to-wall ratio of 3, the reaction temperature of 55° C., and the reaction time of 20 min.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
