Embodiment 1

[0024] (1) 100% cotton fiber plain woven fabric after desizing, scouring, bleaching and mercerizing treatment is first boiled in the aqueous solution containing nonionic surfactant 0.5 g / liter and sodium carbonate 0.5 g / liter for 30 minutes, then After thoroughly rinsing in cold water, dry at room temperature for later use; (2) Add 25 grams of butane tetracarboxylic acid, 10 grams of disodium hydrogen phosphate, 10 grams of magnesium chloride, and nano-TiO in 1000 ml of water. 2 4 grams, 14 grams of TOP-90, and 30 grams of amino silicon emulsion are configured as a working solution; (3) take 120 grams of the fabric treated by (1) and 1 liter of the working solution prepared by (2), and soak the fabric twice Two rolls, liquid rolling rate 75-85%, pre-baked at 80-100°C for 2-5 minutes, then baked at 170-190°C for 1-3 minutes, and finally irradiated by a high-pressure mercury lamp with an illumination of 31000lux for 30- After 60 minutes, take it out and place it in a desiccator ...

Embodiment 2

[0025] Test the nanometer TiO that is made by embodiment 1 2 Dry crease recovery angle, breaking strength, breaking elongation, CIE whiteness value and removal rate of typical pollutants in indoor air of the composite fabric. Among them, wrinkle recovery angle and breaking strength refer to national standards GB 3819-1997 and GB 3923-89 respectively; CIE whiteness value uses Datacolor SPF-600plus color measuring instrument, equipped with Datamatch software of Datamaster system for whiteness test; typical indoor air pollution Ammonia, formaldehyde, benzene and VOCs are tested according to the method in the national standard GB / T18883-2002. All test indicators are carried out according to relevant national standards, and the results are as follows: wrinkle recovery angle is 132°; breaking strength is 405 Newton; CIE whiteness is 137.6; elongation at break is 11.31%. Put a fabric with an area of ​​20 cm × 20 cm into an environmental chamber of 1 cubic meter, under the conditions...

Embodiment 3

[0027] (1) Boil the linen fabric after desizing, scouring, bleaching and mercerizing treatment in an aqueous solution containing 1 g / L of nonionic surfactant and 1 g / L of sodium carbonate for 20 minutes, and then rinse thoroughly in cold water After cleaning, dry it at room temperature for later use; (2) add 10 grams of citric acid, 5 grams of sodium dihydrogen phosphate, 10 grams of magnesium nitrate, nano-TiO 2 10 grams, 20 grams of OP-10, and 25 grams of amino silicon emulsion are configured as a working solution; (3) take 50 grams of the fabric treated by (1) and 1000 ml of the working solution prepared by (2), and soak the fabric twice Two rolls, liquid rolling rate 75-85%, pre-baked at 80-100°C for 2-5 minutes, then baked at 170-190°C for 1-3 minutes, and finally irradiated by a high-pressure mercury lamp with an illumination of 31000lux for 30- After 60 minutes, take it out and place it in a desiccator for 7-9 hours to balance to prepare nano-TiO 2 Composite hemp fabri...

Abstract

A process for preparing the fabric to remove the harmful substances from air, including ammonia, benzene, formaldehyde and volatile organic components, includes such steps as preparing the working liquid from the composite catalyst containing multi-element carboxylic acid, soluble acidic phosphate and soluble Mg salt, nano TiO2, composite dispersed emulsion and antiaging organosilicon, pretreating the plant fibre fabric, and padding in said working liquid.

Description

technical field [0001] The technical solution claimed in the present invention relates to a preparation method of fabric padding treatment with inorganic compound, specifically a preparation method of fabric padding treatment fabric with nano-titanium dioxide dispersion emulsion. Background technique [0002] At present, the application of nanomaterials in the textile industry is mainly manifested in two aspects: first, mixing nanomaterials with polymer spinning solution to make nanocomposite fibers; second, making nanomaterials into dispersion emulsion, and then Anti-ultraviolet finishing, anti-static finishing, anti-bacterial and deodorant finishing or anti-wrinkle finishing are carried out on the fabric by padding method or coating method to obtain special functions such as anti-bacterial and deodorant, anti-ultraviolet, anti-static, and non-ironing properties. Nanocomposite fabrics. US20030013369 describes nanoparticle based durable treatments of fabrics. [0003] As f...
