LIBOLON uses very thin and soft rpet recycled yarn in its block out
functional fabrics. Blackout curtains have a high-density satin weaving
design. The blackout curtain fabric is flame retardant recycled fabric,
and can effectively block out over 99.5% outdoor light penetration. The
LIBOLON functional fabric blackout curtains can be used as flame
retardant curtains, or in video rooms at schools or theaters.
