Flame-retardant Dimout Fabric filters about 95% of harsh light while keeping soft natural daylight, achieving permanent flame retardance through dense weave or light blackout finishing — ideal for offices, living rooms, and daytime bedrooms that balance daylight, privacy, and fire safety.
About 80–95% of harsh light — it softens glare and keeps gentle daylight by day, leaving faint ambient glow at night, unlike near-total blackout.
Is Dimout as Heavy as Blackout?
No. Dimout is lighter and drapes more naturally, suiting offices and living rooms needing a daylight-privacy balance.
When Should I Use Dimout Instead of Blackout?
When the space needs retained daylight (offices, daytime bedrooms, dining areas) and only glare softening, dimout fits better than blackout.
What is Inherent Flame Retardant Blackout Fabric and Dimout Fabric?
BEGOODTEX Inherent Flame Retardant blackout fabric is a type of fabric that combines permanent flame-retardant properties with blackout functionality. It is made of BEGOODTEX’s three-layer permanent flame-retardant polyester yarn (Dimout Fabric), with a blackout rate of approximately 95%. The blackout fabric coating, made of BEGOODTEX’s four-layer shading coating and flame-retardant polyester yarn, can achieve a 100% blackout rate. This fabric offers excellent permanent flame-retardant and blackout performance, effectively preventing the intrusion of sunlight and ultraviolet rays.
The blackout effect of blackout fabrics varies depending on the material used. Dimout fabrics, made from three layers of inherently flame-retardant polyester yarn, have a blackout rate of around 95%. Coated blackout fabrics, made from four layers of blackout coating and flame-retardant polyester yarn, have a blackout rate of 100%.
Flame retardant blackout fabrics are suitable for bedrooms, living rooms, home theaters, offices, and other spaces that require blackout effects. They can be used for fire resistant curtains, room dividers, exhibition displays, train compartment curtains, and more.
The blackout effect of flame retardant blackout fabrics is somewhat related to thickness. Generally, thicker fabrics provide better blackout effects.
In addition to flame retardancy and blackout effects, flame retardant blackout fabrics also offer advantages such as thermal insulation and soundproofing.
No coating and no chemicals, except for coated fabrics.

No, it’s not standard polyester. FR polyester is modified polyester. During the polymerization of polyethylene terephthalate (PET), organic phosphorus-based flame-retardant monomers are incorporated into the reaction system as copolymerization components. Through melt polycondensation, phosphorus atoms chemically form stable P-C bonds with benzene rings in PET molecular chains (by replacing hydrogen atoms on the aromatic rings). The modified polymer is subsequently pelletized to produce flame-retardant PET chips, where the flame retardant achieves molecular-level dispersion and becomes permanently anchored within the fiber matrix.
Yes, the yarn is spun after extrusion, then from POY to FDY or DTY.
