Abstract

The utility model discloses a self-cleaning fabric, which comprises a textile fabric base layer and an oil and water drain layer; and the outer surface of the oil and water drain layer is provided with a convex structure for drainage. The self-cleaning fabric is provided with a nanometer coating for draining water and oil on the surface of the textile fabric; moreover, the rough surface of the self-cleaning fabric can improve the contact corners of water drops or oil drops on the fabric, which drives the water drops or oil drops to fall off on the fabric not to enter the fabric, thereby generating the water and oil drain effects, and simultaneously takes the dirt on the upper surface of the fabric; therefore, the surface has the capacity of 'self-cleaning'.

Description

A kind of automatically cleaning lining

Technical field

The utility model relates to a kind of automatically cleaning lining.

Background technology

Along with the raising of living standard, quality of life, people are more and more higher to the requirement of textiles. and functional textile develops and becomes gradually the main flow of world today's textiles development rapidly.Developed have antiultraviolet, antistatic, anti-electromagnetic radiation, antibiotic, INFRARED ABSORPTION and functional textile such as anti-aging.

Especially for some high-grade fabrics, as woollen, wool class lining, can not clean with common cleaning agent because of its use occasion and characteristic, need dry-clean, the complicated treatment step of specialty such as flatiron, time-consuming taking a lot of trouble, and to the serious wear of lining.And the mode of washing that no matter adopts dry-cleaning or wash all will produce washing agent to the influence of environment and the significant wastage of the energy and resource.

In recent years along with the enhancing of people's environmental consciousness, and to the raising of energy savings understanding, people have constantly carried out the researchs of a large amount of relevant automatically cleaning material technologies, in the hope of energy savings, reduce environmental pollution.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned shortcoming of the prior art, and a kind of automatically cleaning lining is provided.

A kind of automatically cleaning lining of the present utility model, described lining comprise one deck fabric and one deck hydrophobic oleophobic layer, and the outer surface structure of described hydrophobic oleophobic layer has hydrophobic bulge-structure.

In preferred embodiment of the utility model, described hydrophobic oleophobic layer thickness is 10-25 μ m.

In preferred embodiment of the utility model, described bulge-structure size is 5-15 μ m.

In preferred embodiment of the utility model, described hydrophobic oleophobic coating surface has the Nano titanium dioxide particulate.

In preferred embodiment of the utility model, described fabric is a wool fabric.

The utility model is compared its advantage with the prior art scheme:

The nano coating that (1), hydrophobic oleophobic is arranged at fabric face, coarse surface can increase water droplet or the contact angle of oil droplet on lining, thereby make water droplet or oil droplet on lining, tumble, and can not enter in the lining, thereby produce the effect of hydrophobic oleophobic, take away top dirt simultaneously, such surface has just had the ability of " automatically cleaning ".

(2), contain semiconductor ultrafine particle TiO2, transition produces under the effect of light electronics or hole are right. have an effect with dissolved oxygen and water, the free radical of generation can be oxidized to organic pollutant inorganic matters such as CO2 and H2O up hill and dale.The nano self-cleaning technology promptly has the nano material of photocatalytic effect, utilizes natural daylight catalytic decomposition bacterium and pollutant, has high catalytic activity, good chemical stability and heat endurance, non-secondary pollution, nonirritant, characteristics such as safety non-toxic, and can be of value to the ecological natural environment for a long time.

Description of drawings

Fig. 1 is a kind of example structure schematic diagram of the utility model.

Among the figure: 1 is the hydrophobic oleophobic layer, and 2 is fabric, and 3 is bulge-structure.。

The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby protection domain of the present utility model is made more explicit defining so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that.

As shown in Figure 1, comprise one deck fabric 2 and one deck hydrophobic oleophobic layer 3, the outer surface structure of described hydrophobic oleophobic layer 2 has hydrophobic bulge-structure 3.Described hydrophobic oleophobic layer thickness is 10-25 μ m.Described bulge-structure size is 5-15 μ m.Described fabric is a wool fabric.

Principle of the present utility model is the nano coating that hydrophobic oleophobic is arranged at fabric face, the outer surface structure of described hydrophobic oleophobic layer has nano level bulge-structure, form the rough surface under the microcosmic, and coarse surface can increase water droplet or the contact angle of oil droplet on lining, when contact angle was very big, water droplet or oil droplet just presented sphere, and the place that water or oil contact with lining just becomes very little, water droplet or oil droplet just can not stayed in another place like this, can roll over.Only need lining is tilted, thereby make water droplet or oil droplet tumble from lining, and can not enter in the lining, and then produce the effect of hydrophobic oleophobic, take away top dirt simultaneously, such surface has just had the ability of " automatically cleaning ".

Preferably, the Nano titanium dioxide particulate is arranged, can further remove the dirt on the lining, really realize automatically cleaning at described hydrophobic oleophobic coating surface.Semiconductor ultrafine particle TiO2, transition produces under the effect of light electronics or hole are right. and have an effect with dissolved oxygen and water, the free radical of generation can be oxidized to organic pollutant inorganic matters such as CO2 and H2O up hill and dale.The nano self-cleaning technology promptly has the nano material of photocatalytic effect, utilizes natural daylight catalytic decomposition bacterium and pollutant, has high catalytic activity, good chemical stability and heat endurance, non-secondary pollution, nonirritant, characteristics such as safety non-toxic, and can be of value to the ecological natural environment for a long time.

The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
