Support Scrim for Needle Felt Production

Product Overview

Support scrim is the structural backbone of needle-punched filter felt. It provides reinforcement, dimensional stability, and bonding performance essential for long-life, high-efficiency industrial filtration.
Our scrims are engineered using high-performance industrial yarns, optimized weaving structures, and strict tension control to ensure superior compatibility with PET, PPS, Aramid, PTFE, Acrylic, P84 and mixed-fiber felts.

Advanced Manufacturing Platform

High-Speed Looms & Warp-Knitting Machines

We operate imported Picano wide-width projectile looms and biaxial warp-knitting machines, all upgraded specifically for industrial filtration textiles. These modifications enhance fabric evenness, reduce internal stress, and improve needling performance.

Precision Warping Technology

Together with domestic machinery partners, we developed high-precision warping machines tailored for scrim production. This technology guarantees:

• Uniform beam tension across full width

• Flat, smooth fabric surfaces

• No selvedge looseness or distortion

• Better bonding in downstream needling

Patented External Winding System

Our patented winding system delivers neater, perfectly formed rolls up to 1.5 meters in diameter—ideal for high-volume needle felt production.

Premium Raw Material Control

Each scrim is made from specialty industrial yarns sourced from top-tier spinners. Filament strength, linear density, and thermal resistance are strictly controlled to ensure consistent product performance.

Product Advantage

• High tensile and tear strength

• Excellent bonding with needle-punched fibers

• Stable under thermal, chemical, and mechanical stress

• Broad material compatibility (PET, PPS, Aramid, PTFE, Acrylic, P84, blended fibers)

• Customizable weaving patterns and yarn combinations

• Supports long-service-life industrial filter bags
