Sublimation Fabric

Blockout Fabric

Blockout fabric, also known as blackout fabric, is a specialized material designed to block light, providing excellent privacy and light control. Widely used in curtains, roller blinds, and other window treatments, this fabric is particularly popular in residential and commercial settings where light exclusion is desired. The color of blackout fabric is mainly varied by the black yarn and white yarn interlayers, which is ideal for enhancing the room's decor while providing functional benefits.

Curtain blockout fabric is engineered to create a dark, serene environment, making it perfect for bedrooms, home theaters, and conference rooms. The material effectively reduces glare, prevents UV damage, and enhances energy efficiency by insulating against heat and cold. It is also compatible with dye sublimation printing, allowing for custom designs and patterns, making it a versatile choice for creative and functional window coverings.

Blackout fabric for curtains and roller blinds is a practical choice that meets the needs of any space requiring control over natural light and privacy, offering a stylish and effective solution.

Additionally, another application is for making double-sided flags. Different designs can be printed on each side, as the black or white yarn interlayer in the middle ensures the independence of the two designs, preventing any interference between them.
