Description

Technical Field

[0001] The present invention relates to the field of new material technology, in particular to a method for combining nanofibers with traditional textile materials. Background Art

[0002] Methods for introducing nanofibers as new functional materials into traditional textiles have garnered widespread attention. Commonly used methods include: 1) directly depositing nanofibers onto conventional fabrics or yarns as a receiving substrate; 2) depositing nanofibers after treating the fabric surface with solvents or plasma; and 3) adding hot-melt adhesives between the nanofibers and the fabric. The first method results in insufficient bonding between the nanofibers and the fabric, limiting its durability and further application. The second and third methods often compromise the inherent properties of the fabric, such as breathability and softness. Summary of the Invention

[0003] The purpose of the present invention is to address the problems existing in the prior art and provide a method for combining nanofibers with traditional textile materials, thereby increasing the bonding strength between the nanofibers and the traditional textile materials without damaging the fabric itself. To this end, the present invention adopts the following technical solutions:

[0004] A method for combining nanofibers with traditional textile materials, wherein nanorods are grown on the surface of traditional fabrics and then deposited on the nanofibers to increase the friction between the nanofibers and the nanorods or partially embed the nanorods between the nanofibers to improve the adhesion and bonding between the nanofibers and the traditional textile materials.

[0005] On the basis of adopting the above technical solutions, the present invention may also adopt the following further technical solutions, or use these technical solutions in combination:

[0006] The method for combining the nanofibers with traditional textile materials comprises the following steps:

[0007] S1: adding 2-methylimidazole to deionized water and stirring to obtain a dispersed solution of 2-methylimidazole;

[0008] S2: Immerse the fabric or yarn in the above-mentioned dispersion solution, slowly add the zinc source aqueous solution, stir at room temperature, wash and dry, and obtain the fabric or yarn with ZIF-L nanorods growing on the surface;

[0009] S3: using the fabric or yarn with ZIF-L nanorods on the surface obtained in step 2 as a receiving material, depositing electrospun nanofibers;

[0010] S4: Using nitrogen or a negative pressure device to embed the nanofibers between the nanorods to obtain a composite material of nanofibers and textile materials.

[0011] Furthermore, in the dispersed solution, the concentration of 2-methylimidazole is 0.2-0.5 mol / L.

[0012] Furthermore, the fabric is a common fabric such as cotton fabric, polyester fabric, etc., and the yarn is the yarn of these common fabrics.

[0013] Furthermore, the zinc source is zinc acetate, zinc nitrate or zinc chloride, and the concentration of its aqueous solution is 0.3-0.7 mol / L.

[0014] Furthermore, the nanofibers are nanofibers such as PAN, PVA, and PEO.

[0015] Compared with the prior art, the present invention can achieve at least the following beneficial effects:

[0016] 1. The method of combining nanofibers with traditional textile materials provided by the present invention is to grow nanorods on the surface of traditional textiles, increase the friction between nanofibers and nanorods or partially embed nanorods between nanorods to improve the bonding performance between nanofibers and traditional textile materials.

[0017] 2. The method of combining nanofibers with traditional textile materials is a physical combination that does not require additional adhesives and is green and environmentally friendly.

[0018] In the present invention, the above-mentioned technical solutions can be combined with each other to achieve more preferred combinations.

BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 2 Schematic diagram of the combination of PAN nanofibers and cotton fibers in Example 1; Specific embodiments

[0022] Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiments are only used to illustrate the present invention and do not limit the scope of the present invention.In addition, should be understood that after reading the present invention's teaching content, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall equally within the scope limited by the appended claims of the application. Example

[0023] (1) Dissolve 5.74 g of 2-methylimidazole in deionized water and stir to dissolve to obtain an aqueous solution of 2-methylimidazole. Then place the cotton fabric vertically in the solution and soak for 5 minutes.

[0024] (2) Dissolve 1.363 g of zinc chloride in deionized water to obtain an aqueous solution of zinc chloride, and then slowly add it dropwise to the solution in step (1) and stir at room temperature for 3 hours. After the reaction is completed, take out the cotton fabric and wash it with ethanol to obtain the cotton fabric with ZIF-L nanorods, dry it and set aside. Figure 1 As shown, the surface of cotton fibers can be seen covered with ZIF-L nanorods.

[0025] (3) Weigh 1 g of PAN powder and dissolve it in 9 g of DMF solution to obtain a 10% PAN electrospinning solution.

[0026] (4) Using the fabric or yarn from step (2) as the receiving material, PAN nanofibers are deposited on it. Then, a negative pressure device is used on the side of the cotton fabric where no nanofibers are deposited to improve the bonding between the PAN nanofibers and the cotton fabric, such as Figure 2 As shown, it can be seen that the nanofibers are tightly combined with the cotton fibers, and some nanofibers are embedded between the nanorods.
