Fire Retardant Reflective Fabric Production principle
The principle of the reflection cloth is to make the glass microbeads of high refractive index coated or coated in the surface of the bucky, so that the ordinary fabric can reflect the light in the light of the light.
Reflective cloth USES: mainly used in road traffic safety related products, widely used in reflective clothing, all kinds of professional wear, overalls, fashion, shoes and hats, gloves, bags, personal protective supplies, outdoor supplies, etc., can also be made into all kinds of reflective products, accessories.
The classification of the reflective cloth: can be divided into two kinds, one is in the traditional sense of the reflective cloth, another is reflective print cloth, reflective print color cloth is also called crystal lattice was launched in 2005, a new kind of reflective material can print. The characteristics of this material are based on the microprism regressive reflection technology, which has a reflective intensity of 300cd/lx/m2, with super reflective intensity. The surface layer is PVC polymer material, and the ink is strong and can be painted directly. The base material type has fiber synthesis cloth and PVC calender film, the fiber synthesis fabric base has strong tensile strength, can be used as ordinary fiber synthetic spray cloth. Direct spray painting, direct taut installation, PVC compressional film can be used directly in any smooth fabric after coating the adhesive to use, easy to use. Reflector is made of reflective and lamp-box cloth base. According to its reflective structure, it can be divided into standard reflective material, wide-angle reflector material and sky star reflective material. Reflective print cloth after the print can be made into large outdoor billboards, used for highway, roads, mining and other outdoor environment, night without lighting, only vehicle light and allows the contents of advertisements is clear and bright, has the same effect during the day.
Base material of reflective cloth: according to different base material, TC (65% chemical fiber, 35% cotton), chemical fiber (100% chemical fiber).
The brightness of the reflective cloth: according to different anti-light brightness points, bright silver reflective cloth, highlighted reflective cloth, conforms to the European standard EN20471 and the standard ANSI standard, the brightness is greater than 330cd/lux. m2; Bright reflective cloth brightness at 10cd/lux. M2. Of course, many products with high brightness can reach up to 400-500cd/lux.m2.
Application classification of reflective cloth: regular reflective cloth, elastic reflective cloth, flame retardant reflective cloth.
Reflective fabric belongs to a series of products, in the field of personal safety protection in the field of personal safety protection and several major series of products for the hot press, reflective leather, reflective silk/line, reflective products (reflective ribbon, reflective crystal lattice, reflective article package edge, reflective lettering, reflective accessories, reflective printing trademark, etc.).
Reflective materials are based on microprism reflection. We all know that reflection of light is diffuse and specular reflection, why to return to reflective material can according to the original road return the lights Actually, this is mainly attributed to the high refractive index glass beads of contains. When a beam of light within a certain range to illuminate any Angle to the bead surface, due to the high refraction of beads concentrated on beads back surface reflector, reflector to reflect the light along the direction of the incoming light parallel. Forming regression reflection. When many glass beads reflection at the same time, will appear in front of the light.
Experiments show that when the refractive index of a glass beads close to 1.9, the incoming light can get well focus on the surface of glass beads after, when the return of the reflection effect is best, when the refractive index is less than or greater than 1.9, the incoming filling line focus respectively on the glass of outside and inside, then the return of the reflective effect will be reduced. Because of the influence of the objective conditions in practical use. Glass beads of refractive index is usually between 1.9 2.1, and it is usually less than 0.8 mm in diameter. If in the back of the glass beads add a layer of reflector, then return to the reflective effect is better.
