Roller Shades Fabric Series 12 : Cationic Polyester Slub Fabric

We’re back with another cationic polyester fabric (check our past blogs for more on cationic polyester fabrics!), but this one’s got a twist—a chic slub linen texture. What makes it even cooler? You get to choose between two versions: Light-Filtering for soft ambiance or Blackout for total light control. Style meets function, tailored to your needs!

Material Breakdown

The basic light-filtering version is crafted with 100% polyester, where cationic dyeing technology brings out its delicate linen-inspired texture. To preserve the fabric’s organic appeal while boosting durability, a transparent polyurethane (PU) coating is applied to the surface. 

For those seeking ultimate light control, the upgraded blackout version takes it a step further. This heavyweight blend combines 60% polyester with 40% kaolin clay–titanium dioxide composite, engineered through a triple-layer coating process. The result? Near-total darkness alongside functional upgrades like thermal insulation and noise reduction—perfect for creating a serene, distraction-free environment.

How It’s Made

Both versions start with dyeing—a process that locks color deep into the fibers for fade-resistant vibrancy. From there:

  • The Light-Filtering fabric gets a sleek PU spray coat for stain resistance.
  • The Blackout fabric goes through precision coating machinery to apply its light-blocking composite layer on the backside, hitting a whopping 99% light-blocking rate.
