Drylaid Carding and Cross-Lapping Machinery
category
Drylaid nonwoven production uses carding machines to open and parallelise staple fibres into a thin web followed by cross-lapping or randomising to build a web of defined weight and orientation, providing the fibre web structure for subsequent bonding into nonwoven fabrics with controlled thickness, weight, and mechanical properties for hygiene, filtration, insulation, and geotextile applications.
Role
Provides the most versatile fibre web formation route for nonwoven production by processing the widest range of natural and synthetic staple fibres into controlled-weight webs through carding and layering equipment, enabling production of nonwoven fabrics from 15 to 3000 grams per square metre with tailored fibre orientation from isotropic to highly anisotropic for diverse technical application requirements.
