Window Screen with High Light Transmittance & UV-Resistant Performance
Traditional window screens may be good at shading, preventing ultraviolet ray or ventilating, but their integrate function are deficient. So, a function often gets promoted through sacrificing another function, for example, UV-resistant window screens with poor air permeability and light transmittance. in light of this situation, this essay will introduce a new kind of window screen which can ensure both high light transmittance and UV-resistant performance.
Window screens with high light transmittance and UV-resistant performance adopt full-dull polyester filament as main material. This kind of filament full of nano-sized TiO2 and TiO2 is a stable and non-toxic UV absorber which can absorb, reflect and scatter ultraviolet rays. In addition, by adding titanium dioxide, this kind of window screens has higher relative density that enhance their drapability.
HLT-01: Window screens with high light transmittance and UV-resistant performance adopt full-dull polyester filament as main material.
HLT-02: By adding titanium dioxide, window screens with high light transmittance and UV-resistant performance has higher relative density to enhance their drapability.
Influence factors on window screens with high light transmittance and good UV-resistant performance:
- Adopting full-dull polyester filament, window insect screens with high light transmittance and good UV-resistant performance can reduce UV transmittance under the premise of good light. It can also keep visible light transmittance above 50% and control UV transmittance from 20% to 25%. Although coating technology has good anti-ultraviolet performance, its light transmission effect is poor and it is not suitable for the production process of fabric with high light transmittance and low ultraviolet.
- Fabrics woven by spun yarn have good air permeability which become lower with the increase of density.
- The impact of full-dull polyester filament on window screens' air permeability performance is not clear. However, window screens woven by this kind of material possesses great ventilation function.
