Problems solved by technology

However, it is only suitable for lightly polluted and well-ventilated indoor environments, and the persistence of air pollutant removal is not good, and it cannot be infinitely adsorbed. After a period of time, the purification effect will decrease or even not adsorb. It needs to be replaced and the cost will increase.

Embodiment 1~4

[0024] Embodiment 1~4 provides the method for textile loaded nano titanium dioxide, described method comprises the following steps:

[0025] Nano-titanium dioxide pretreatment: Weigh 2.0773g of nano-titanium dioxide particles, respectively add silane crosslinking agent or acrylic acid crosslinking agent whose mass is 30% of the mass of nano-titanium dioxide particles, and 10% of the mass of nano-titanium dioxide particles. Polyether phosphate or acrylic acid-(meth)acrylate copolymer, the specific ratio is shown in Table 1, then added to 500mL ethanol solution with a mass fraction of 20%, adjust the pH to 9, 30kHz ultrasonic treatment for 1h, and dry to obtain the surface Modified treated nano titanium dioxide particles.

[0026] Preparation of nano-titanium dioxide dispersion liquid: Weigh 1.5024 g of improved nano-titanium dioxide particles, add 0.8% fatty alcohol polyoxyethylene ether of nano-titanium dioxide particle quality and 0.6% epoxy ethylene ether penetrating agent o...

Embodiment 5~12

[0037] Embodiments 5 to 12 compared the functional fabrics obtained by cross-linking agents and dispersant dosages of different proportions, and compared the decolorization rate of rhodamine B decolorization test and the aldehyde removal rate experiment. The method comprises the following steps:

[0038] Nano-titanium dioxide pretreatment: Weigh 2.5057 g of nano-titanium dioxide particles, add acrylic acid crosslinking agent whose mass is 10%, 30%, and 40% of the mass of nano-titanium dioxide particles, and 10%, 20%, and 40% of the mass of nano-titanium dioxide particles. 30% alkylphenol polyether phosphate, the specific ratio is shown in Table 2, then added to 500mL ethanol solution with a mass fraction of 20%, adjust the pH to 9, 30kHz ultrasonic treatment for 1h, and dry to obtain surface modified Nano titanium dioxide particles.

[0039] Preparation of nano-titanium dioxide solution: Weigh 1.9924 g of improved nano-titanium dioxide particles, add 0.8% fatty alcohol polyoxy...

Embodiment 13~16

[0049] Embodiments 13 to 16 are basically similar to the method of embodiment 11, the difference is that in the step cold rolling process, the cold rolling process adopted: the cloth processed by the load is placed in the pre-treatment liquid for padding for chemical , the material temperature is 45°C, and the padding pretreatment liquid includes 35g / L of QR-cold pile agent and 10g / L of 100% hydrogen peroxide. The cold pad batch was washed at room temperature for 6, 9, 15, and 18 hours respectively, washed twice at 95°C, once at 80°C, twice at 15°C, and finally dried at 105°C to obtain a functional cloth.

[0050] The load fastness test was carried out to the functional cloth of loaded nano-titanium dioxide obtained in Examples 13-16. The specific test method is to put the functional cloth obtained in the above-mentioned embodiment into the steel used for testing the color fastness to washing in the textile industry respectively. In the cup, add an appropriate amount of steel ...

Abstract

The invention discloses a photocatalyst pillowcase, a preparation method of the photocatalyst pillowcase, and a throw pillow. The preparation method comprises the following steps of S1, preparing a titanium dioxide dispersion liquid, that is, putting nano titanium dioxide particles, an auxiliary agent and a solvent into a container, performing mixing, adjusting the pH value to 5-10, carrying out ultrasonic dispersion at 20-40 kHz for 2-5 minutes, and obtaining a uniform nano titanium dioxide dispersion liquid; S2, carrying out cloth loading, that is, putting cloth into the nano titanium dioxide dispersion liquid, and continuously stirring; S3, carrying out cold rolling treatment, that is, treating the cloth by adopting a cold rolling process to prepare a functional cloth; and S4, manufacturing the pillowcase, namely, sewing the functional cloth into the pillowcase. The preparation method is simple in process, the process flow is shortened, the cost is lowered, and the preparation method is more environment-friendly. The amount of loaded nano titanium dioxide in the prepared functional cloth is more, the load fastness is high, and the performance is more stable. The throw pillow disclosed by the invention comprises a pillow core and a pillowcase prepared by using the method, and an effect of long-acting cleaning can be kept at the same time due to the fact that stains contaminated by daily use can be degraded.

Description

technical field [0001] The invention relates to a daily necessities pillow, in particular to a preparation method of a photocatalyst pillowcase, a photocatalyst pillowcase and a pillow. Background technique [0002] Throw pillows are common items in household life. Similar to pillows, the common ones are only half the size of ordinary pillows. Holding them in your arms can keep you warm and protect you to a certain extent. It gives people a warm feeling, and now it has become a common accessory for home use and decoration and a must-have item for car decoration. Generally idle and bored on the sofa, hug and play while watching TV, with the improvement of people's living standards, more and more pillows are close to people's lives, and become indispensable for home life, office white-collar workers, car interior decoration, etc. decorations. [0003] The shape and structure of a pillow are similar to that of a pillow, and they are relatively large. Today, users have undergo...
