Embodiment 1

[0025] refer to figure 1 , a method for preparing a multifunctional cotton fabric loaded with Cu-MOFs, the specific steps are as follows:

[0026] Step 1, adopt butane tetracarboxylic acid to modify cotton fabric: after cotton fabric is soaked in the aqueous solution that contains 4wt% butane tetracarboxylic acid and 4wt% sodium hypophosphite 5min, roll and press with paddle car, two Dip twice. The padded cotton fabric was prebaked at 100°C for 3 minutes, and finally baked at 180°C for 3 minutes to obtain a modified cotton fabric.

[0027] Step 2: Load Cu-MOFs onto cotton fabrics by layer-by-layer assembly method: configure 0.02M copper nitrate trihydrate aqueous solution A, and immerse the modified cotton fabrics in solution A for 10 min. Then add 0.02M nanometer ZnO dispersion liquid into the solution A, stir rapidly to form the hydroxyl double salt solution B, and continue to soak the modified cotton fabric in the solution B for 10 minutes before taking it out. With etha...

Embodiment 2

[0029] refer to figure 2 , a method for preparing a multifunctional cotton fabric loaded with Cu-MOFs, the specific steps are as follows:

[0030] Step 1, using citric acid to modify the cotton fabric: immerse the cotton fabric in an aqueous solution containing 4wt% citric acid and 4wt% sodium hypophosphite for 5 minutes, and then use a paddle car to perform rolling, two dipping and two rolling. The padded cotton fabric was prebaked at 100°C for 3 minutes, and finally baked at 180°C for 3 minutes to obtain a modified cotton fabric.

[0031] Step 2: Load Cu-MOFs onto cotton fabrics by layer-by-layer assembly method: prepare 0.1M copper sulfate pentahydrate aqueous solution A, and immerse the modified cotton fabrics in solution A for 10 min. Then add 0.1M nanometer ZnO dispersion liquid into solution A, stir rapidly to form hydroxyl double salt solution B, and the modified cotton fabric is continuously soaked in solution B for 10 minutes and then taken out. With ethanol and N...

Embodiment 3

[0033] refer to image 3 , a method for preparing a multifunctional cotton fabric loaded with Cu-MOFs, the specific steps are as follows:

[0034] Step 1, adopt butane tetracarboxylic acid to modify cotton fabric: after cotton fabric is soaked in the aqueous solution that contains 4wt% butane tetracarboxylic acid and 4wt% sodium hypophosphite 5min, roll and press with paddle car, two Dip twice. The padded cotton fabric was prebaked at 100°C for 3 minutes, and finally baked at 180°C for 3 minutes to obtain a modified cotton fabric.

[0035]Step 2: Load Cu-MOFs onto cotton fabrics by layer-by-layer assembly method: configure 0.05M copper chloride dihydrate aqueous solution A, and immerse the modified cotton fabrics in solution A for 10 min. Then add 0.05M nanometer ZnO dispersion liquid into the solution A, stir rapidly to form the hydroxyl double salt solution B, and continue to soak the modified cotton fabric in the solution B for 10 minutes before taking it out. With ethan...

Abstract

The invention relates to the technical field of functional textile preparation, in particular to a preparation method of a Cu-MOFs loaded multifunctional cotton fabric, which comprises the following steps: step 1, modifying a cotton fabric by using polycarboxylic acid; step 2, loading the Cu-MOFs on the cotton fabric at room temperature by adopting a layer-by-layer assembly method, and endowing the cotton fabric with multiple functions of antibiosis, adsorption, photocatalysis and the like. According to the preparation method, carboxyl is introduced to the cotton fabric, copper ions are adsorbed, then a layer-by-layer assembly method is adopted, the copper ions are combined with ZnO nano particles, a (Zn, Cu) hydroxyl double-salt intermediate is formed, the anion exchange rate is increased, and Cu-MOFs are rapidly loaded to the cotton fabric at the room temperature. The method has the characteristics of low energy consumption, simple equipment, convenience in operation and the like. The prepared multifunctional cotton fabric loaded with Cu-MOFs has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of preparation of functional textiles, in particular to a method for preparing multifunctional cotton fabrics loaded with Cu-MOFs. Background technique [0002] Metal-organic frameworks (MOFs) are a new class of porous materials formed by the coordination assembly of organic ligands and inorganic structural units (metal ions or metal clusters), with micropores, mesoporous and macroporous structures. It has a wide range of applications in the fields of gas phase adsorption and separation, liquid phase adsorption and separation, drug release, photocatalysis and antibacterial. Copper is one of the essential trace elements for the human body. Although it has good biocompatibility, it is difficult for traditional copper nanoparticles to control the release rate of metal ions during antibacterial, and it will also cause certain damage to normal tissues of the human body. Compared with copper nanoparticles, Cu-MOF...
