High Quality Weaving Monofilament for Industrial Filter Screen & Printing Screen Mesh

Performance Requirements of Monofilament for Screen Weaving

Verification of Basic Physical Indicators

         Microscope sampling inspection is adopted to check the monofilament diameter uniformity. The diameter deviation shall be controlled within ±3% to prevent uneven mesh openings of finished screen cloth. A third-party test report shall be provided to verify breaking strength and elongation at break, to match the tension requirement of weaving machines and reduce filament breakage risk during weaving.

Special Performance Matching by Application Scenarios

       Printing screen: Select high-elastic monofilament with smooth surface and excellent ink permeability, which can withstand repeated friction of squeegee. Industrial filter screen: Focus on alkali resistance and dilute acid resistance to adapt to chemical medium service environment.

Check of Weaving Process Compatibility

          The heat setting temperature of monofilament shall be 170℃~180℃ to ensure flat screen surface and stable tension after weaving. Pre-stretched monofilament is preferred to reduce tension loss after screen stretching and avoid screen slackening failure.

Pilot Weaving Test with Samples

           Purchase small-batch samples for machine trial weaving to inspect surface defects such as fuzz and filament knots. Mass procurement can be carried out only after the weaving efficiency and finished screen quality are verified qualified.
