Description
Technical Field
The invention relates to a daily life article pillow, in particular to a preparation method of a photocatalyst pillowcase, the photocatalyst pillowcase and a throw pillow.
Background
The throw pillow is a common article in household life, is similar to a pillow, is only half the size of a common pillow, and can play a certain role in warming and protecting when being held in the arm. The decorative material gives people a warm feeling, and becomes a common ornament and a necessary article for vehicle decorations for home use and decoration. Generally, people feel bored when holding the pillow on a sofa for playing when watching television, and with the improvement of the living standard of Chinese people, the pillow is more and more close to the life of people, and becomes an indispensable ornament for home life, office white collar, in-car decoration and the like.
The throw pillow and the pillow have almost the same shape and structure, the square is larger, the user can develop to the present day, the color collocation, the shape collocation, the functional requirements and the material requirements of the throw pillow are all changed greatly, the DIY throw pillow is more appeared, people feel more sometimes still advance colors, and more people can feel that the throw pillow is a good choice.
At present, sofa throw pillows, automobile throw pillows, bed pillows and the like are mainly adopted, and health care pillows, electric massage pillows, decorative throw pillows and the like are distinguished according to functionality. Wherein the sales volume of the air purification function in various malls is increased year by year.
The air purification throw pillow on the market at present is mainly a throw pillow carrying an activated carbon adsorption technology, carbon-containing fibers are used as precursor materials, and after stabilization treatment is carried out at a certain temperature, high-temperature carbonization treatment is carried out. The surface of the treated activated carbon fiber is provided with a large number of micropores, so that the activated carbon fiber has excellent adsorption performance. The prepared activated carbon fiber can be used as the inner filler or the outer sleeve material of the throw pillow.
The cost of the activated carbon is low, and the large number of micropores on the surface of the fiber endows the fiber with extremely large surface area and high adsorption capacity and efficiency. But only suitable for indoor environment with light pollution and good ventilation, the air pollutant removal durability is poor, infinite adsorption cannot be realized, the purification effect is reduced or even not adsorbed after a period of time, replacement is needed, and the cost is increased.
Disclosure of Invention
The invention aims to overcome at least one defect of the prior art, and provides the preparation method of the photocatalyst pillowcase, which has the advantages of simple process, reduced process flow and reduced cost, and the functional cloth prepared by processing has a large amount of loaded nano titanium dioxide, high load fastness and more stable performance.
The invention also provides a photocatalyst pillowcase and a throw pillow, wherein the pillowcase is prepared by the method, the throw pillow comprises a pillow core and the pillowcase prepared by the method, and the pillow core is made of high polymer elastic materials such as PP, POE or EVA. So as to reduce organic pollution gas such as formaldehyde, TVOC and the like in the air, degrade stains on the surface of the throw pillow due to daily use and keep the effect of long-acting cleaning.
The throw pillow comprises a photocatalyst pillowcase and an inner core which have the function of removing indoor air pollutants such as formaldehyde, and the inner core filler used by the photocatalyst throw pillow still adopts polypropylene fiber with high strength, high toughness, good chemical resistance and good biological resistance, namely PP cotton, and is widely applied to the field of clothing products. The pillow case adopts various flannelette tissues such as plain flannelette, velvet, flocked fabric, polyester silk fabric flannelette and the like, so that the throw pillow has thick texture, wear resistance, durability, good heat retention and plump hand feeling.
The invention adopts the technical scheme that a preparation method of a photocatalyst pillowcase is provided, and the preparation method comprises the following steps: s1: preparing a titanium dioxide dispersion liquid: placing nano titanium dioxide particles, an auxiliary agent and a solvent into a container, mixing, adjusting the pH to 5-10, and dispersing for 2-5 minutes at 20-40 kHz ultrasonic wave to obtain a uniform nano titanium dioxide dispersion liquid; s2: and (3) distributing load: putting the cloth into the nano titanium dioxide dispersion liquid, and continuously stirring; s3: cold rolling treatment: processing the cloth by adopting a cold rolling process to prepare functional cloth; s4: manufacturing a pillowcase: the functional cloth is sewn into a pillowcase.
The throw pillow made of the activated carbon fiber cannot keep the air purification effect for a long time due to the limitation of the adsorption capacity of the activated carbon; the throw pillow made of the fiber loaded with the nano titanium dioxide photocatalyst can degrade air pollutants such as formaldehyde and TVOC in the air, has the functions of degerming, bacteriostasis and self-cleaning due to the photocatalytic function of the nano titanium dioxide, and has long-term and stable photocatalytic function without replacement.
Further, in step S3, the cold rolling process includes the following steps: and (4) placing the cloth treated in the step (S2) into a padding pretreatment solution for material melting, cold rolling at room temperature for 6-18 h, washing for 2 times at 90-100 ℃, 5-10 min/time, washing for 1 time at 70-85 ℃, 5-10 min/time, washing for 2 times at 10-25 ℃, preferably 15 ℃, 2-8 min/time, and finally drying at 80-110 ℃ for 20-60 min. The formaldehyde-removing throw pillow can be prepared by the method within the range restricted by the invention.
Further, the padding pretreatment liquid comprises 25-45 g/L of QR-cold batch agent and 5-15 g/L of 100% hydrogen peroxide, and the material melting temperature in the step S3 is 40-50 ℃.
