Product Overview
The Spun-Bond Edge-Wrapped Filter Mesh Assembly (also known as edge-wrapped filter screen, filter disc, or chemical fiber filter assembly) is a critical filtration component used in synthetic fiber spinning production lines. This product is manufactured by precisely layering metal filter meshes of various mesh counts with support meshes, followed by an edge-wrapping process. It is widely used in melt filtration applications across chemical fiber spinning, plastic granulation, nonwoven fabric production, and leather manufacturing. The assembly effectively removes mechanical impurities and gel particles from molten polymers, ensuring spinneret orifices remain clear, improving spinning solution purity, and guaranteeing final product quality.
