Deeprotect™ Material specializes in the production of fireproof cloth series products using fire-resistant fiberglass fabric as the base material. Each production step involves precision equipment and process controls to ensure product quality.
As the core foundation of production, this step employs an optimized multi-stage process:
Glass fiber yarn is processed using a Karl Mayer DS 21/30NC sectional warping machine at low speed (<200 m/min), with ionized air guns to eliminate static electricity and ensure uniform yarn tension.
Epoxy-based sizing agents (temperature ≤60°C) are applied via a Benninger Sucker-Muller sizing machine, followed by curing with a Tsudakoma LHS-500 low-temperature dryer to enhance yarn abrasion resistance.
- Rapier Loom (e.g., Picanol OMNIplus-X): Equipped with an electronic let-off system (EBC) to control tension fluctuation ≤±2%, suitable for plain/twill weaving (weft density: 60–80 picks/inch) and high-density fabrics (300–800 g/m²).
- Dobby Loom(e.g., Stäubli CX-860): Utilizes 16–24 lightweight heald frames for complex structures (e.g., 2/2 twill) in multi-layer composite fireproof materials.
- Special Applications：Shuttle looms with ceramic-modified yarn channels can produce low-weight fiberglass fabric (<200 g/m²), though efficiency is 30% lower than rapier looms.
