Leno Scrim - Technical Fabric

Leno scrim (also known as “filled scrim” in theatrical & stage contexts) is a weave in which the warp yarns are twisted or crossed around the weft yarns, creating a locked mesh structure. This locking prevents the yarns from shifting, allowing for a more stable, slightly denser open-weave that retains airiness but adds improved tear resistance and dimensional stability, especially against distortion when coated or subjected to tension.

Parameter                             Typical Range / Notes

Weave Type                         Leno weave (twisted warp locking each weft thread)

Yarn Materials                     Cotton, Polyester, PP, Nylon, sometimes blended with synthetics; also              

                                                used with FR (flame retardant) yarns in some fabrics

Yarn Denier / Size               Can range depending on use; for stage drapes lighter weights, for 

                                                industrial reinforcements heavier yarns can be used

Openness/Mesh Density    More open than a solid fabric, but less open than plain scrim at same                                       

                                               density due to leno locks; good for light diffusion or reinforcement 

                                               where you want some airflow or permeability  

Width                                    Commonly made in wider widths especially in textile/stage sector; 

                                               custom widths possible

Tensile / Tear Strength       Enhanced tear strength compared to plain weave scrim because of 

                                                the locking effect; good dimensional stability under load or 

                                               when laminated/coated  

• Stage, theater & film backdrops where light diffusion and soft edges are needed
   
• Filled cloth scrims for “drop” backdrops and visual effects
   
• Reinforcement layers in membranes where slight openness is acceptable but slippage needs to be minimal
   
• Wallcoverings, laminates, acoustic fabrics, or where a combination of durability + some air permeability is required
   

• Reduced yarn shifting compared with plain weave → more stable mesh
   
• Better tear resistance
   
• Improved edge stability and less distortion under tension
   
• Maintain some openness (for coatings, airflow, light diffusion) while being stronger than very open scrims
