Problems solved by technology

However, nano-ZnO finishing agents are currently applied to more functional finishing at the same time. For example, there are still few methods and processes that have anti-ultraviolet, antibacterial and hydrophobic properties, and there are generally certain deficiencies in the effect, and the production cost is high.

Embodiment 1

[0026] In the zinc nitrate salt aqueous solution that mass percent concentration is 2.0%, slowly add the citric acid of 1 times amount, stir continuously, until citric acid dissolves completely, obtain nano-zinc sol; Cotton fabric is in the nano-zinc sol that bath ratio is 20:1 Immerse for 1 hour and pre-bake at 80°C for 2 minutes; mix stearic acid, water and ethanol in a mass ratio of 1:10:1 to obtain a water-repellent agent; after that, the fabric is dipped twice in the water-repellent agent and rolled twice, The liquid-carrying rate is 85%, pre-baked at 80°C for 3 minutes, and baked at 170°C for 3 minutes to obtain a nanometer anti-ultraviolet and antibacterial hydrophobic cotton fabric.

Embodiment 2

[0028] Slowly add 2 times the amount of citric acid into the zinc acetate aqueous solution with a mass percentage concentration of 5%, and continue to stir until the citric acid is completely dissolved to obtain the nano-zinc sol; the cotton fabric is dipped and rolled twice in the nano-zinc sol, Rate 85%, pre-baked at 80°C for 3 minutes. Sodium palmitate, acetic acid, water and isopropanol are mixed in a mass ratio of 1:0.05:10:1 to obtain a water-repellent agent; after that, the fabric is immersed in the water-repellent agent with a bath ratio of 25:1 for 30 minutes , pre-bake at 80°C for 1 minute, and bake at 170°C for 1 minute to obtain a nano-scale anti-ultraviolet and antibacterial hydrophobic polyester fabric.

Embodiment 3

[0030] Slowly add 1 times the amount of citric acid in the zinc sulfate aqueous solution with a mass percentage concentration of 0.1%, and continue to stir until the citric acid is completely dissolved to obtain the nano-zinc sol; the polyester fabric is in the nano-zinc sol with a bath ratio of 30:1 Immerse for 20 minutes and pre-bake at 70°C for 3 minutes. Mix palmitic acid, water and butanol at a mass ratio of 1:30:5 to obtain a water-repellent agent; after that, the fabric is soaked in the water-repellent agent with a bath ratio of 25:1 for 30 minutes, and pre-baked at 70°C for 3 minute, and baked at 150° C. for 3 minutes to obtain a nanometer anti-ultraviolet and antibacterial hydrophobic polyester fabric.

Abstract

The invention relates to a method for finishing nano anti-ultraviolet and antibacterial hydrophobic fabrics. The method comprises the following steps: (1) adding citric acid with mass being 0.5-2 times that of zinc salt to zinc salt aqueous solution with mass percent concentration being 0.1-5.0% and stirring the mixture until the citric acid is completely dissolved to obtain nano zinc sol; (2) mixing long chain fatty acid, water and alcohol or mixing long chain fatty acid salt, organic acid, water and alcohol to obtain a water repellent; and (3) padding or impregnating the fabrics in the nanozinc sol and then pre-drying the fabrics, then padding or impregnating the fabrics in the water repellent and pre-drying and baking the finished fabrics, thus obtaining the nano anti-ultraviolet and antibacterial hydrophobic fabrics. The method has the following beneficial effects: the method is simple and is easy to industrialize; the used raw materials have low cost and do not have toxic or side effects; and the fabrics finished by the method have excellent hydrophobic property, simultaneously have excellent anti-ultraviolet and antibacterial properties and have good application prospects.

Description

technical field [0001] The invention belongs to the field of finishing hydrophobic fabrics, and in particular relates to a finishing method for nanometer anti-ultraviolet and antibacterial hydrophobic fabrics. Background technique [0002] Fabrics or textile fibers are easily stained when they come into contact with water-containing stains. Hydrophobic treated fabrics, with their unique self-cleaning and anti-pollution properties, have many undesirable phenomena related to water droplets, such as surface pollution , snow accumulation, oxidation, current conduction, and fluid viscosity can also be effectively contained. It can be widely used in medical personnel clothing, rain / snow clothing, tents, military combat uniforms, etc., and is increasingly favored by people. [0003] In recent years, due to the air pollution caused by the rapid development of industry, the ozone layer in the atmosphere has been destroyed, and the function of absorbing ultraviolet rays has been weake...
