Embodiment 1

[0026] Under room temperature and vigorous stirring, a uniform mixed solution of 20 grams of tetrabutyl titanate and 6 grams of acetic acid was added dropwise to 85 mL of a 0.4% hydrochloric acid solution by mass, and then stirred in a water bath at 60 ° C for 30 minutes to obtain transparent nano-TiO 2 Hydrosol. Incorporate cotton fabrics in nano-TiO 2 Double immersion and double rolling in the hydrosol, with a liquid loading rate of 80%, pre-baking at 80°C for 2 minutes; at room temperature, mix magnesium stearate, nitric acid, water and ethanol with a mass ratio of 1:0.5:20:2.5, and stir for 0.5 hours , to obtain a water repellent; the nano-TiO 2 The finished cotton fabric was immersed in a water repellent agent with a bath ratio of 25:1 for 0.5 hour, pre-baked at 80°C for 4 minutes, and baked at 170°C for 2 minutes to obtain an anti-ultraviolet and antibacterial self-cleaning cotton fabric.

Embodiment 2

[0028] Under room temperature and vigorous stirring, a uniform mixed solution of 20 grams of tetrabutyl titanate and 4 grams of propionic acid was added dropwise to 80 mL of a 0.45% hydrochloric acid solution by mass, and then stirred in a water bath at 50 ° C for 60 minutes to obtain a transparent nanometer TiO 2 Hydrosol. Incorporate polyester fabric in nano-TiO 2 Double immersion and double rolling in hydrosol, with a liquid loading rate of 90%, pre-baking at 80°C for 2 minutes; at room temperature, mix magnesium stearate, citric acid, water and ethanol with a mass ratio of 1:1.5:30:5, and at room temperature Stir for 2 hours to obtain water repellent; Nano TiO 2 The finished fabric was dipped and rolled twice in the water repellent agent, with a liquid retention rate of 85%, pre-baked at 70°C for 3 minutes, and baked at 170°C for 2 minutes to obtain an anti-ultraviolet and antibacterial self-cleaning polyester fabric.

Embodiment 3

[0030] Under room temperature and vigorous stirring, a uniform mixed solution of 20 grams of ethyl titanate and 6 grams of propionic acid was added dropwise to 90 mL of a 0.3% nitric acid solution by mass percentage, and then stirred in a water bath at 60 ° C for 40 minutes to obtain transparent nano-TiO 2 Hydrosol. Incorporate polyester fabric in nano-TiO 2 Two-dipping and two-rolling in the hydrosol, liquid-carrying rate 100%, pre-baking at 60°C for 4 minutes; at room temperature, zinc stearate, nitric acid, water and propanol with a mass ratio of 1:0.7:30:4 were mixed, and at room temperature Stir for 1 hour to obtain water repellent; Nano TiO 2 The finished fabric was immersed in a water repellent agent with a bath ratio of 15:1 for 30 minutes, pre-baked at 80°C for 1 minute, and baked at 150°C for 1 minute to obtain an anti-ultraviolet and antibacterial self-cleaning polyester fabric.

Abstract

The invention relates to a method for clearing up a nanometer uvioresistant antibacterial self-cleaning fabric. The method comprises the steps of: (1) mixing a titanium slat with an organic acid in a mass ratio of 10:(1-3), stirring the mixed solution uniformly, then adding the mixed solution into an inorganic acid solution to react at 50-60 DEG C for 30-60 minutes, so as to obtain nanometer TiO2clearing up liquid; (2) soaking and rolling the fabric twice in the nanometer TiO2 clearing up liquid; (3) mixing stearate, hydrolyst, water and alcohol at room temperature to react for 0.5-2 hour toobtain a water repellent; and (4) padding or soaking the fabric mentioned in step (2) in the water repellent, pre-drying and baking the fabric cleared up in a manner of water repellence, thus obtaining a nanometer uvioresistant antibacterial self-cleaning fabric. The method disclosed by the invention is simple and easy to industrialize, and the treated fabric has good self-cleaning performance and also has good uvioresistant and antibacterial performances, so the nanometer uvioresistant antibacterial self-cleaning fabric has good application prospect.

Description

technical field [0001] The invention belongs to the field of self-cleaning fabric finishing, in particular to a finishing method of nanometer anti-ultraviolet and antibacterial self-cleaning fabric. 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, the harm of excessive ultraviolet radiation to the human body has attracted people's attention. Nano-TiO2 is an inorganic ultraviolet shielding agent, which can effectively shield the UVA and UVB...
