Specialty Cross-Sections [20]
A modified cross-section can provide added functionality, such as unique lustre or moisture transport.
These cross-sections are available in staple, filament and microfibre forms, and in most cases, are
also available as bi-component fibres. Typical microfibres with special cross-section shape, commonly
used, are presented in Figure 3; many application find especially the hollow fibres (Figure 3a).
