Breakthrough in Blackout Roller Blind Fabric Technology

Recently, Changzhou Yameite Window Decoration Co., Ltd. obtained a utility model patent for "a high-uniformity anti-agglomeration blackout roller blind fabric structure." The design employs a double-layer transitional structure that effectively eliminates coating agglomeration, achieving a color difference (ΔE) of ≤1.2 and a peel strength of 8.6–9.4 N/cm².

The structure consists of a base fabric layer, a flame-retardant layer, a primary blackout layer, two transition layers, and a surface layer. The first transition layer combines rutile titanium dioxide with a polycarboxylate dispersant, while the second uses anatase titanium dioxide with a polyurethane thickener, forming a gradient-density interface. This structure is particularly suitable for high-precision digital-printed blackout blinds in industrial production.
