Soft Enough to Roll, Stiff Enough to Stay Flat
Roller blinds face a special challenge: if the fabric is too stiff, it won't roll up easily; if it's too soft, it sags and looks untidy. The key property is bending stiffness. Our Fly Mesh Roller Blinds have a warp bending stiffness of 80–120 mN·m. At this range, the fabric rolls up smoothly and springs back flat when released-no wrinkles, no sagging. This fabric is engineered precisely for this purpose.
Every Batch Tested for Bending Stiffness
We don't guess whether the fabric meets the standard-we measure it. Every batch undergoes a bending stiffness test, and the result is recorded on the specification sheet. You can also verify it with a third-party lab-the difference will be less than 10%. We also control fabric skew, which refers to distortion along

Three Steps to Keep the Fabric Straight
Maintaining a straight fabric is challenging. We use a three-step process: first, smart tension control on the warping machine; second, skew checks every 2 hours during weaving; third, adjustment during heat setting. This ensures skew stays below 2%. Nanping Jinwei developed this Fly Mesh Roller Blinds fabric after eight months of testing. Standard orders ship in 16 days, and custom samples are ready in 14 days. You pay 30% upfront. The fabric resists edge curling and maintains its shape over time.
