Problems solved by technology

When the water-repellent fabric is washed many times in practical application, the nano-SiO2 particles on the surface of the fiber will completely fall off, and the water-repellent film will be broken, resulting in poor water-repellent effect or even no longer exist.

Embodiment 1

[0028] Add 3g of tetraethyl orthosilicate to a mixture of 95mL of ethanol and 5mL of deionized water, stir vigorously at 20°C for 4h, gradually add 6ml of ammonia water dropwise, continue to add 2g of precursor, stir for 6h, add 2g of azido Undecyltriethoxysilane, continue to stir for 4h to prepare nano-modified SiO containing azido functional group 2 Sol.

[0029] Using flat screen printing, the nano-modified SiO2 sol finishing paste containing azide functional groups was printed on pure cotton fabrics, dried at 80°C for 5 minutes, and irradiated with ultraviolet rays for 6 minutes.

[0030] Use AATCCTM195-2009 "Liquid Moisture Management Characteristics of Fabrics" to test the moisture transfer and quick-drying performance after finishing, measure 3 times at different positions of the same sample, and take the average value. The measured one-way transmission index reached 265.1928.

Embodiment 2

[0032] Add 3g of tetramethyl orthosilicate to a mixture of 90mL of ethanol and 10mL of deionized water, stir vigorously at 30°C for 3h, gradually add 5ml of ammonia water dropwise, continue to add 3g of precursor, stir for 8h, then add 3g of azidoform Phenylethyltrimethoxysilane, continue to stir for 5h, and prepare nano-modified SiO containing azido functional group 2 Sol.

[0033] Using flat screen printing, the nano-modified SiO containing azido functional groups 2 The sol finishing paste was printed on pure cotton fabrics, dried at 85°C for 4 minutes, and irradiated with ultraviolet rays for 8 minutes.

[0034] Use AATCCTM195-2009 "Liquid Moisture Management Characteristics of Fabrics" to test the moisture transfer and quick-drying performance after finishing, measure 3 times at different positions of the same sample, and take the average value. The measured one-way transmission index reached 277.8914.

Embodiment 3

[0036] Add 2g of methyltrimethoxysilane to a mixture of 85mL of ethanol and 15mL of deionized water, stir vigorously at 40°C for 2h, gradually add 4ml of ammonia water dropwise, continue to add 4g of precursor, stir for 8h, then add 3g of azidopropane base triethoxysilane, and continued to stir for 5 h to obtain a nano-modified SiO2 sol containing azido functional groups.

[0037] Using flat screen printing, the nano-modified SiO2 sol finishing paste containing azide functional groups was printed on pure cotton fabrics, dried at 90°C for 3 minutes, and irradiated with ultraviolet rays for 10 minutes.

[0038] Use AATCCTM195-2009 "Liquid Moisture Management Characteristics of Fabrics" to test the moisture transfer and quick-drying performance after finishing, measure 3 times at different positions of the same sample, and take the average value. The measured one-way transmission index amounted to 176.673.

Abstract

The invention relates to a preparation method for low-carbon photocuring single-side moisture transport finishing agent. The method comprises the following steps: (1) a precursor is poured in a mixture of ethanol and de-ionized water, and is acutely stirred at the temperature of 10-40 DEG C; and (2) catalyst-ammonia water is slowly dripped to stir, then different-chain-length alkyl containing an azide group or siloxane of aromatic hydrocarbon is added to continuously stir in order to obtain low-carbon and energy-conservation single-side moisture transport finishing agent containing an azide functional group. The finishing agent has stable properties; finished fabrics obtain excellent single-side moisture transporting performance and durability, and need no heat baking, so that a large amount of energy is saved; the finishing agent accords with the national modern economic development theme of environmental protection and low energy consumption, and has wide market application prospect and excellent social benefit.

Description

technical field [0001] The invention belongs to the field of textile functional finishing agents and their preparation and application, in particular to a low-carbon light-curing one-way moisture-conducting finishing agent and its preparation method and application. Background technique [0002] With the improvement of living standards, people have higher and higher demands on the suitability and functionality of leisure and sports textiles. People look forward to high-quality products, and their desire to pursue health, comfort and taste is growing. Special functional textiles emerge in endlessly, and the trend of interpenetration and integration of casual wear and sportswear is increasingly favored by consumers. Athletes will excrete a lot of sweat when they engage in strenuous competitive sports, and the stickiness and damp feeling brought by sweat often affect the athlete's state. How to keep the body surface dry and comfortable during exercise is an important research t...
