Description

Formaldehyde-removing curtain fabric

Technical Field

The utility model relates to an indoor air pollution purifies technical field, especially relates to a remove formaldehyde casement.

Background

An investigation from world banks shows that our country currently loses annually due to indoor air pollution, if estimated by the value of willingness to pay, is about $ 106 billion. Various health problems caused by indoor pollution have become prominent public health problems. The fact that people feel more attentive proves that indoor air pollution becomes an invisible killer which is harmful to human health and also becomes a common concern of all countries around the world. Research shows that the pollution degree of indoor air is 2-5 times more serious than that of outdoor air, and can reach 100 times under special conditions. Thus, indoor air pollution has been classified in the united states as one of 5 major environmental factors that endanger human health. The world health organization also lists indoor air pollution as 10 major threats to human health, together with hypertension, hypercholesterolemia, obesity, and the like. Statistically, nearly half of the people worldwide are in indoor air pollution, which has caused 35.7% of respiratory diseases, 22% of chronic lung diseases and 15% of tracheitis, bronchitis and lung cancer. The technology is advanced, the Internet is developed, the traditional life style of human is changed, people can arrange any things without going out, and the time of people in a closed environment is naturally increased greatly. At present, at least more than 70% of the time a human being spends indoors, whereas urban populations spend more than 90% indoors, especially for infants and elderly, disabled people. A large number of home decoration materials such as wall paints, floors, furniture, glues, etc. are used in the home decoration process. These building materials release harmful gases such as VOCs (volatile organic compounds), benzene, toluene, xylene, TVOC (total volatile organic compounds), and the like, such as formaldehyde, which is the most harmful pollutant in home air pollution, to various degrees. Formaldehyde is a colorless gas with pungent smell, has carcinogenicity besides strong stimulation effect on mucous membranes of eyes, nose and throat, and has a release period as long as 3-15 years under general conditions, so that how to adopt an effective method to remove VOCs such as formaldehyde in indoor air becomes an urgent problem to be solved. The traditional curtain cloth usually used indoors at present only has basic use functions and does not have the effect of removing formaldehyde, so that the development of the curtain cloth which not only has the basic use functions, but also can remove the formaldehyde has positive significance for improving the indoor air quality.

Disclosure of Invention

In order to solve the problems existing in the prior art, the utility model aims to provide a formaldehyde-removing curtain fabric, which can meet the living needs of people and can catalyze and decompose formaldehyde, thereby improving the indoor air quality.

The technical scheme of the utility model as follows: the formaldehyde-removing curtain fabric is characterized in that a textile printing layer, a lining cloth layer and a textile printing layer are sequentially compounded from top to bottom through a hot-pressing adhesion process, the textile printing layer is made of 3/1 twill or 2/2 twill, wherein the warp adopts photocatalyst yarn, and the weft adopts polyester yarn or polyester cotton yarn; the lining cloth layer is formed by at least three layers of gauzes, and porous adsorption particles and photocatalytic decomposition particles are attached to the interlayer of the gauze.

In a further limited technical scheme of the utility model, in the formaldehyde-removing curtain fabric, the porous adsorption particles are activated carbon particles, diatomite or vermiculite particles; the photocatalytic decomposition particles are nano titanium dioxide or nano zinc oxide.

In the formaldehyde-removing curtain fabric, in order to improve the overall strength of the curtain fabric, the weft in the lining cloth layer is blended with the carbon fiber yarns, and the weft stress in the vertical direction of the curtain fabric can be borne by the carbon fiber yarns when the curtain fabric is used.

According to the formaldehyde-removing curtain fabric, the specifications of the warp and weft of the textile printing layer are not more than 20tex, the integral thickness of the curtain fabric can be controlled on the premise that the formaldehyde is removed, and the thickness of the curtain fabric is controlled to facilitate installation and use due to the fact that the curtain fabric is of a composite layer structure.

In the formaldehyde removing curtain fabric, a plurality of rows of hollow-out air holes are arranged on the surface of the textile printing layer at equal intervals, the interval between each row of air holes is 80-110cm, and the aperture of each air hole is 10-20 mm. The curtain cloth is integrally formed by hot pressing, so that the air permeability of the cloth is poor, and when the curtain cloth is used as the curtain cloth, the air permeability of the curtain cloth cannot meet the requirement of the curtain cloth, so that the air permeability of the curtain cloth is met by arranging the air holes.

Further, the gauze of the formaldehyde removing curtain cloth is cotton gauze, linen gauze or polyester cotton gauze. The thickness of the lining cloth layer is 1-10mm, and the thickness of the textile printing layer is 1-5 mm.

The technical effects of the utility model: the utility model discloses a three-layer surface fabric is compound to be made, through the special selection of weaving mode and silk thread on weaving stamp layer, the photocatalyst yarn that will have absorption formaldehyde of maximize exposes in the outside, plays the purpose of purifying environment. Secondly, the lining cloth layer is added into the composite fabric, and the particles capable of adsorbing formaldehyde and decomposing formaldehyde are added into the lining cloth layer, so that the purpose of removing formaldehyde is further achieved, peculiar smell can be removed through the added porous adsorption particles, air is purified, and the purpose of removing peculiar smell is achieved.
