It should be said that people have long realized that the use of screens to block the invasion of mosquitoes, so the building materials doors and windows industry in the early installation of windows and doors at the same time an additional track configuration fixed push-pull frame, so to some extent ease the entry of mosquitoes into the room. With the promotion of eco-friendly, simple home improvement, people realized that stacking gauze in winter without screens would increase the service life of the gauze. Therefore, folding screens came out and became popular because the gauze could be folded together. People can not see, as the name implies, "invisible."
Roller shade screen is a new type of reform and improvement based on folding screens. It is also an inevitable trend of development instead of folding screens. Because the screen is completely opened and laid out, and the screen is not visible in the distance, it is called " "Invisible", completely wraps the gauze into the pipe.

First, the choice of gauze
The quality of screens is, first and foremost, gauze. Yarn has domestic and imported points. Most of the imported fiber material; domestic glass fiber, there are some plastic material. Imported high-quality fiber screens can be tens of thousands of push-pull friction without distortion; domestic glass fiber generally only withstand a few thousand times; and plastic screens because of the material relationship, easy thermal expansion and contraction, the possibility of deformation. Therefore, imported fiber screens should be selected.
There are two points to pay attention to when purchasing gauze:
1, see. See if the net hole of the net is uniform; whether the thickness of the yarn is even;
2, touch. Good quality imported gauze feels quite scratchy, like the general feel of iron burned
