Because the stay cord is hidden in the hollow layer, the appearance is perfect, the use is simpler and more practical than the traditional cloth art curtain, and the honeycomb curtain is natural and elegant in fold, so that the honeycomb curtain has unique texture. Cellular curtains are typically made of woven or nonwoven materials (e.g., nonwoven fabrics) that are folded and thus extend and retract from top to bottom. The honeycomb curtain is in a three-dimensional folded prismatic shape when seen from the front, and a curtain-shaped structure which is similar to honeycomb-shaped hexagonal holes is formed when seen from the side, so that the effects of light shielding, heat insulation, sound insulation and noise reduction are achieved.

However, the existing honeycomb curtains adopt metal springs as traction members, but the metal springs have high manufacturing cost, high carbon emission in the manufacturing process, complex installation and frequent industrial accidents.
