Nonwoven Carding Machine Design and Configuration
topic
Nonwoven carding machines use wider working widths of 2.5 to 5.5 metres and higher production rates than textile carding, with multiple worker-stripper roller pairs on the main cylinder and a doffer roll delivering a continuous thin web at 20 to 150 grams per square metre at production speeds of 50 to 200 metres per minute, with stationary carding segments replacing revolving flats to achieve the high production rates required for nonwoven manufacturing economics.
Role
Forms the thin primary web from staple fibre input that provides the foundation layer for cross-lapping or direct bonding in drylaid nonwoven production, with carding machine working width, production speed, and web weight uniformity being the primary process parameters that determine the raw material throughput capacity and web quality that govern the production economics and product quality potential of the drylaid line.
