[0002] Fabric is the material used to make clothing. The quality of fabric directly affects the quality of the entire piece of clothing. Fabrics of different materials have different effects. People usually choose clothes of different fabrics and cuts according to their needs and seasons to show their own style.

[0003] In daily life, people sweat when they are working or exercising, or when it is hot. This will cause the sweat to adhere to the fabric of the clothes they wear. When the fabric is wet, it will adhere to people's skin, making it difficult for the sweat to be discharged and dried in time, affecting the dryness of people's skin and the comfort of the clothing fabric, so there is room for improvement.

[0006] By adopting the above technical scheme, after the finishing agent is coated on the surface of the fabric body, a finishing coating is formed on the surface of the fabric body. The finishing coating has good hydrophobic properties, improves the hydrophobic properties of the fabric body, and reduces the occurrence of sweat adhering to the fabric body after the fabric is worn, thereby improving the dryness of the fabric and thus improving the comfort of the fabric. The bio-based hydrophobic finishing component in the finishing coating is prepared by rosin intermediates and hydroxyethyl cellulose, and the bio-based hydrophobic finishing component is obtained by grafting and modifying natural renewable resources as raw materials.

[0051] Example 12 Example 12 is based on Example 3. The difference between Example 12 and Example 3 is that in Example 12, no ferric chloride solution is added when preparing the antibacterial microcapsule component.

[0052] Comparative Example 1 Comparative Example 1 is based on Example 3, and in Comparative Example 1, the rosin intermediate in the bio-based hydrophobic finishing component is replaced with an equal amount of hydroxyethyl cellulose.

[0053] Comparative Example 2 Comparative Example 2 is based on Example 3, and in Comparative Example 2, the antibacterial microcapsule component is replaced with ordinary lavender essential oil.

[0054] Performance testing The comfortable fabrics of Examples 1-12 and Comparative Examples 1-2 were subjected to the following performance tests: (1) Hydrophobic performance test The contact angle of the prepared sample surface was tested. Three points were randomly selected for each sample and tested three times. The average value was taken and the test results were filled in Table 1.

[0055] (2) Antibacterial performance test According to GB / T 20944.1 Evaluation of antibacterial properties of textiles, the antibacterial performance of the samples was tested and tested again after 7 days. Each sample was tested 3 times, the average value was taken, and the test results were filled in Table 1.

[0056] (3) Washability test According to GB / T3921-2008 Textiles - Colour fastness to washing with soap - Test standard, the samples were tested for their water washability. Each sample was tested 3 times, the average value was taken, and the test results were filled in Table 1.

[0057] Table 1 Performance test results of Examples 1-12 and Comparative Examples 1-2 Data analysis From Table 1, it can be seen that the hydrophobic angles of Examples 1-3 are all 160° and above, indicating that the comfortable fabric prepared by the present application has good hydrophobic properties; the antibacterial rates of Escherichia coli and Staphylococcus aureus of the samples of Examples 1-3 are both 99.90% and above, and the antibacterial rates of Escherichia coli and Staphylococcus aureus are both above 96.00% after 7 days, indicating that the comfortable fabric prepared by the present application has good antibacterial properties and can achieve long-term antibacterial effects; the color fastness of Examples 1-3 is all at level 5, indicating that the comfortable fabric prepared by the present application has good water washability.

[0058] When preparing the hydrophobic preform in Example 4 and Example 5, the mass ratio between the rosin intermediate and the hydroxyethyl cellulose is not within the range specified in the present application. When the content of hydroxyethyl cellulose is too little, the carbon content in the system is low, the grafting rate is reduced, and the ring-opening reaction is difficult to be sufficient, thereby affecting the quality of the prepared rosin intermediate; when the content of hydroxyethyl cellulose is too much, the ring-opening reaction reaches saturation and it is difficult to further improve the grafting performance of the product, and ungrafted components remain in the system, so the grafting rate of the system is reduced, and the various performances of Example 4 and Example 5 are reduced.

[0059] In Example 6 and Example 7, when preparing the hydrophobic finishing components, the proportion of the hydrophobic preform is not within the range specified in the present application. When the content of the hydrophobic preform is too little, the content of the rigid phenanthrene hydrogen ring of the rosin is low, and the hydrophobic performance is difficult to be further improved. When the content of the hydrophobic preform is too much, the interface adsorption of the entire hydrophobic finishing component reaches saturation, and the stability of the system is reduced. Therefore, the overall performance of Example 6 and Example 7 is reduced.

[0060] In Example 8 and Example 9, when preparing the antibacterial microcapsule component, the mass ratio of the added lavender essential oil to 3-methacryloyl dopamine is not within the range specified in the present application. When the content of 3-methacryloyl dopamine is too little, on the one hand, it is difficult to cover all the lavender essential oil, and some effective antibacterial components are free in the system and quickly oxidized and inactivated. On the other hand, the adhesion performance between the antibacterial microcapsule component and the fabric body is difficult to be further improved, the stability is reduced, and the effective antibacterial components are lost after washing, and the stability is reduced; when the content of 3-methacryloyl dopamine is too much, the excessive 3-methacryloyl dopamine is difficult to fully dissolve in the system, and due to the steric hindrance effect, the adhesion performance of the antibacterial microcapsule component on the fabric is reduced, and the water washing resistance is also reduced; therefore, the various performances of Example 8 and Example 9 are reduced.

[0061] The concentrations of the ferric chloride solutions added in Examples 10 and 11 are not within the range specified in the present application. When the concentration of ferric chloride is too high, the stability of the system will be reduced. When the concentration of ferric chloride is too low, the catechol functional groups of 3-methacryloyl dopamine are difficult to fully react with Fe 3+ Metal coordination bonds are formed between the prepared antibacterial microcapsules and the fabric body, and the bonding performance between the prepared antibacterial microcapsules and the fabric body is difficult to further improve.

[0062] In Example 12, no ferric chloride solution was added, and the 3-methacryloyl dopamine system was difficult to form a stable coordination structure, so the stability was reduced, and the bonding performance with the fabric was difficult to be improved.

[0063] In Comparative Example 1, the bio-based hydrophobic finishing component does not use dehydroabietal alcohol to modify hydroxyethyl cellulose, so it is difficult to improve the hydrophobic properties of hydroxyethyl cellulose and to obtain a stable spatial structure. The effect of adhesion to the fabric body is also reduced, so the stability of Comparative Example 1 is reduced.

[0064] In Comparative Example 2, 3-methacryloyl dopamine was replaced with lavender essential oil, and the uncoated antibacterial component was rapidly oxidized and inactivated, and the antibacterial effect was reduced.

[0065] This specific embodiment is only an explanation of the present application, and it is not a limitation of the present application. Through the above description, relevant staff can make various changes and modifications without deviating from the technical idea of ​​the present application. The technical scope of the present application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
