Abstract
The utility model discloses a photochromic fabric. Backing cloth consists of a fabric in the level A or B according with the GB18401 National Textile Product Basic Safety Technical Specifications; a photochromic coating layer is arranged on the backing cloth; and methyl cellulose (MC) photosensitive powder is uniformly distributed in the photochromic coating layer. The photochromic fabric can be changed into different colors according to the difference of the used MC photosensitive powder under the illumination of sunshine and changed back to the original color in a room, and the color change is reversible. The MC photosensitive powder of the photochromic fabric does not contain substances harmful to a human body and is more environmentally-friendly. In the photochromic fabric, only one face or one part of the face of the backing cloth is coated with the photochromic layer, and the other face next to the skin is made of the material of the backing cloth, so that the wearing comfortableness cannot be reduced.
Description
Technical field
The utility model belongs to the weaving face fabric field, and is particularly related to a kind of fabrics and fibers.
Background technology
Ultraviolet ray is divided into three kinds by different-waveband, and wavelength is UVC below 250nm, wavelength 250-320nm with interior be UVB, wavelength 320-380 with interior be UVA.Visible-range is 380-800nm, and the infrared light scope is 900-1800nm.And some photochromic material can utilize the energy of UVA that the light sensitive molecule key is opened at present; Make it jump to the high energy rank from the low energy rank; Promptly jump to visible light from black light, thus colorific variation, when losing ultraviolet ray irradiation or temperature rising above 45 ℃; The light sensitive molecule key is closed, and promptly is returned to original color.Photochromic material is emerging in the world in recent years one type of new function material, and it not only is applied in high-tech area, and also shows up prominently in civilian industry.External having is used for the products for civilian use such as clothes, plastics on a small quantity, causes the concern and the attention of man of every industry or trade.
Photochromic material can stop illumination or heat returning to original colourless state again very soon by the colourless or light shades of colours such as redness, green, blueness, purple that become under daylight or other light sources irradiation, is reversible variable color process.The purpose of research is to be used for optical information storage, light regulation and control, photoswitch, optics material, optical information gene material, modifier chip material etc. in the world.
The maximum country of research photochromic material is the U.S., Japan, France etc. at present, and Japan's exploitation on civilian industry is compared early.At present, have only the Japan and the U.S. to have a small amount of photochromic material civil goods to sell in the world.But developed countries such as U.S.A, day are used for civilian industry to photochromic material and yet are in the starting stage; Not large-scale production listing; The domestic product of not seeing that also photochromic material is produced; The anti-counterfeit recognition trade mark that has only China to be used for antiforge material occurs on some tobacco and wine product, therefore develops photochromic material, on civil goods is used, very big development space and vast market is arranged.
The utility model content
The utility model is in order to overcome existing photochromic material civil goods less defects, and the utility model provides a kind of photochromic lining, has the function of changeable colour in the sun.
The technical scheme of the utility model is: a kind of photochromic lining; A or the lining of B grade by reaching in " GB18401 country textile product basic security technical specification " constitute base fabric; On base fabric, be provided with photochromic coating, even distribution MC sensitizing powder in the described photochromic coating.
Described photochromic coating covers whole base fabric or only covers the part of base fabric.
The thickness of described photochromic coating is 0.1 ~ 0.8mm.
The thickness of described base fabric is 0.5 ~ 5mm.
Beneficial effect
1. the photochromic lining of the utility model can conversion goes out various colors with the difference of the MC sensitizing powder that uses under solar radiation, can become original color again again indoor, is a reversible process.
2. the MC sensitizing powder of the utility model does not contain harmful material, environmental protection relatively.
3. the photochromic lining of the utility model is because only in the one side of base fabric or the topical application photochromatic layer of one side, the one side that wears next to the skin still is the material of base fabric itself, so can not reduce wearing comfortableness.
4. used MC sensitizing powder is numerous in variety, makes that the color of lining also can be changeful.
5. the cost of used MC sensitizing powder is cheap, can not increase the too many cost of production.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein 1 is base fabric, and 2 is photochromic coating, and 3 is the MC sensitizing powder.
The specific embodiment
Further explain below in conjunction with 1 pair of the utility model of accompanying drawing.
A kind of photochromic lining constitutes base fabric 1 by the A or the lining of B grade that reach in " GB18401 country textile product basic security technical specification ", such as using cotton, fiber crops, real silk, wool etc.On base fabric 1, be provided with photochromic coating 2, even distribution MC sensitizing powder 3 in the described photochromic coating.The MC sensitizing powder is a microcapsules nuclear core, and it is synthetic for the shell material to add Malamine, forms the sensitization discoloration pigment of 1-10um, and water content can be heat-resisting 280 ℃ below 0.3%.MC powder Essential colour has MC#12 purple, MC13# skyblue, MC#14 purplish blue, MC#16 is yellow, MC17# is orange, MC#19 is red.Discolouration is good and stable.Mobile high, easy and uniform is disperseed, and can mix each other, also can be shared with other pigment, fluorescent pigment.
Described photochromic coating 2 covers whole base fabric 1 or only covers the part of base fabric 1.When covering local time, can apply into certain pattern, will demonstrate prior coated pattern so in the sun.And through selecting for use different MC sensitizing powders can also show various colors.So and because only apply the comfort level that one side can not influence dress.
The thickness of described photochromic coating 2 is 0.1 ~ 0.8mm.The thickness of described base fabric 1 is 0.5 ~ 5mm.The color of base fabric 1 will be selected light color system as far as possible, at high temperature is exposed to the sun for a long time and can shortens the service life of photochromic coating.
Claims (4)
1. photochromic lining constitutes base fabric by the A or the lining of B grade that reach in " GB18401 country textile product basic security technical specification ", it is characterized in that, on base fabric, is provided with photochromic coating.
2. photochromic lining according to claim 1 is characterized in that, described photochromic coating covers whole base fabric or only covers the part of base fabric.
3. photochromic lining according to claim 1 is characterized in that, the thickness of described photochromic coating is 0.1～0.8mm.
