preparation example Construction

[0037] The preparation method of the fabric with deodorizing function of the present invention is specifically implemented according to the following steps:

[0038] Step 1, modification of β-cyclodextrin or preparation of sulfo-β-cyclodextrin:

[0039] 1) Measure concentrated sulfuric acid and β-cyclodextrin with a mass fraction of 70% to 90% respectively, the mass ratio between concentrated sulfuric acid and β-cyclodextrin is 5 to 6:1, pour the measured concentrated sulfuric acid Put the beaker with concentrated sulfuric acid into the beaker, then put the beaker with concentrated sulfuric acid into an ice bath, add the weighed β-cyclodextrin into the beaker with concentrated sulfuric acid at 0°C~5°C and stir for 1h~2h, Form a reaction solution, add distilled water to the reaction solution, the volume ratio of the reaction solution to distilled water is 1:15~25, and configure the reaction solution A;

[0040] 2) Take calcium carbonate and pour it into the reaction solution A...

Embodiment 1

[0067] Measure concentrated sulfuric acid and β-cyclodextrin with a mass fraction of 90% respectively, the mass ratio between concentrated sulfuric acid and β-cyclodextrin is 5.5:1, pour the measured concentrated sulfuric acid into a beaker, and then put the Put the beaker with concentrated sulfuric acid in an ice bath, add the weighed β-cyclodextrin into the beaker with concentrated sulfuric acid at 0°C and stir for 1 hour to form a reaction solution, pour the reaction solution into distilled water, The volume ratio of reaction liquid and distilled water is 1:25, is configured as reaction liquid A, gets calcium carbonate and pours in reaction liquid A, tests the pH value of reaction liquid A simultaneously to the pH of reaction liquid A is 7.0, stops adding calcium carbonate, Filter the reaction solution B, filter the generated calcium sulfate precipitate, wash the calcium sulfate precipitate with water, and then combine the washed calcium sulfate precipitate with the filtrate...

Embodiment 2

[0073] Measure concentrated sulfuric acid and β-cyclodextrin with a mass fraction of 80% respectively, the mass ratio between concentrated sulfuric acid and β-cyclodextrin is 5:1, pour the measured concentrated sulfuric acid into a beaker, and then put the Put the beaker with concentrated sulfuric acid in an ice bath, add the weighed β-cyclodextrin into the beaker with concentrated sulfuric acid at 3°C ​​and stir for 2 hours to form a reaction solution, pour the reaction solution into distilled water, The volume ratio of reaction liquid and distilled water is 1:20, is configured as reaction liquid A, gets calcium carbonate and pours in reaction liquid A, tests the pH value of reaction liquid A simultaneously to the pH of reaction liquid A is 6.5, stops adding calcium carbonate, Filter the reaction solution B, filter the generated calcium sulfate precipitate, wash the calcium sulfate precipitate with water, and then combine the washed calcium sulfate precipitate with the filtrat...

Abstract

The invention discloses a method for preparing fabric with a deodorizing function. The method comprises steps of modifying beta-cyclodextrin or preparing sulfonic group-beta-cyclodextrin; preparing a finishing liquor by using the prepared sulfonic group-beta-cyclodextrin, and conducting the grafting for the fabric by using the finishing liquor; and conducting the catechins inclusion for the grafted sulfonic group-beta-cyclodextrin fabric. The method is environment-friendly. The beta-cyclodextrin and the derivate of the beta-cyclodextrin are novel environment-friendly non-toxic finishing agents, the catechins is a natural deodorizer, the beta-cyclodextrin and the derivate of the beta-cyclodextrin are used for finishing the fabric through the catechins inclusion, the fabric has good deodorant, health and environment-friendly functions and is good in washable performance, the added value of textile products is improved, and the application prospects are wide. The fabric after being finished can remove odor molecules at the fetor environment, the fabric is fresh and comfortable and a user feels good.

Description

technical field [0001] The invention belongs to the technical field of functional fabric processing, and in particular relates to a preparation method of a fabric with deodorizing function. Background technique [0002] During the use of textiles, especially clothing, odor will be generated during the wearing process. This is because textiles are a kind of porous material, which is easy to absorb various impurities in gas phase, liquid phase and solid phase, and become the breeding carrier of bacteria. , resulting in an odor. There are two main sources of odors: odors generated on fabrics and odors absorbed from the environment. As far as our daily living environment is concerned, the odors adsorbed on clothes mainly include the odors of cigarette smoke and lampblack. [0003] Deodorizing finishing is a high-functional finishing technology that has developed rapidly since the 1990s. Textiles after deodorizing finishing have better hygienic and health care functions. The i...
