Reflective polarizers containing polymer fibers

The invention claims a polarizer, wherein by the following: pathAnd a fibre is in a matrix the main parallel intervals. The polymer fibre is made at least a first polymer material and second polymer material. The polymer matrix and first polymer material and connected with the second polymer material at least one of the double refraction, and forms a double the interface between the adjacent material. According to the light sensitivity, wherein the is reflected and/or the scattering the double the interface of. The are capable solution, wherein the polymer fibre to form for complex fibre, wherein a is placed in the filler multiple scattering polymer fibre is formed with a complicated fibre. The other solution, wherein the polymer fibre is the multi-layer polymer fibre. The polymer fibre can be one part in of fibre composite is arranged in the polymer matrix.
