Description

Technical Field

[0001] This utility model relates to the field of textile technology, and more specifically, it relates to a dual-functional fabric with high light transmittance and high shading. Background Technology

[0002] The application of home textile fabrics not only decorates spaces and meets the diverse needs of modern people, but also injects more cultural connotations into the living environment and enhances its artistic conception. Home textile fabrics of different materials and textures can reflect different lifestyles. Among home soft furnishing fabrics, curtains are an indispensable decoration, and have become a carrier for expressing personal thoughts and lifestyle.

[0003] As an interior textile that combines functionality and decoration, window screens, with their "light-permeable but privacy-blocking" characteristic, are increasingly becoming an important requirement in modern home design. Traditional window screens, while allowing light to pass through, often face the challenge of privacy protection—overly thin fabrics, while ensuring ample light, easily expose indoor activities to the outside world; while increasing fabric density can improve shielding, it often leads to a significant decrease in light transmittance and deterioration in breathability. This contradictory characteristic has prompted the textile industry to continuously explore the balance between optical performance and visual privacy, driving the development of new functional window screens.

[0004] From an optical mechanism perspective, the "light-permeable but not human-permeable" effect relies on the fabric's precise control over the visible light spectrum. When incident light penetrates the window screen, the microstructure design on the yarn surface induces multiple diffuse reflections and refractions, effectively disrupting the propagation path of the transmitted light while maintaining overall light transmittance. Current mainstream solutions encompass three technological approaches: first, high-count, high-density weaving technology, which uses precisely arranged warp and weft yarns to create micron-level pores, allowing visible light to pass through while blocking clear imaging of the human body's contours; second, optical processing technology, employing nano-coatings or embedded microbeads to alter the propagation characteristics of transmitted light using the principle of light wave phase modulation; and third, innovative composite structures, such as developing a double-layer heterogeneous yarn structure, where the outer layer handles light scattering while the inner layer maintains mechanical properties, achieving functional layered optimization.
