Description

Technical Field

[0001] The present invention relates to the technical field of fabrics, and in particular to a durable full-light-blocking honeycomb curtain fabric and a preparation method thereof. Background Art

[0002] There are many types of curtains, including roller blinds, pull blinds, and honeycomb blinds. Honeycomb blinds, also known as accordion blinds, are popular among the general public for their UV protection and heat insulation properties. Honeycomb blinds generally consist of a top bar, a bottom bar, and honeycomb fabric with threading holes. The fabric is connected to the top and bottom bars via cords through the threading holes. Honeycomb blinds are generally made of non-woven fabric.
