Introdution of the anti-reflective flock sheet

The anti-reflective black material is very important for both photography and optical research. Unnecessary reflection of light causes a decrease in contrast and produces noise, which impairs the accuracy and aesthetics. The purpose of an anti-reflective black material is to absorb such unnecessary light and obtain a clear image.

The shiny needles are also mysterious when viewed from the needle tip in a bundle. The content is that the tip of the needle bundle looks black. The light that enters between the needles is reflected into the bottom of the bundle many times, attenuates, and hardly returns, so it looks black. The surprising point of this experiment is that even a glittering surface of silver can produce black with repeated reflections.

A similar phenomenon occurs on the surface of hair transplants. The pile that stands upright by electrostatic flocking paper sheet is like a dense bundle of needles.

The light-absorbing blackout material has a surface that looks somewhat like felt. That is, the flocked hair is not standing upright, but is set randomly. It does not seem to be electrostatic flocking.

It is most likely a processing method of dropping or spraying pile on an object coated with adhesive. It is the same feeling as the Flocky painting.

The light absorption property is not the best, probably because the hair is not upright compared to electrostatic flocking. The difference is obvious when compared to our anti-reflective flock sheet with electrostatic flocking. However, the blackout material can be obtained at a low price, so the cost performance will be sufficient.

But what can you tell by looking at this lining photo? Anti-reflective black flocking paper are a slightly stiff rayon base material, it lacks flexibility and it is difficult to handle.
