1. What are the main barriers to entry for new players in the woven filter fabric market?
High barriers come from long baghouse OEM qualification cycles, technical control over polymer weaving and needle-punching, and the need to prove PM2.5 abatement performance. A new entrant typically needs $8-12 million in capital and 18-24 months of field trials before it wins meaningful replacement orders from cement, power, or chemical plants.
