Definitions
- Comparative Examples D, E and F show the effect of an infrared based solvent stripping with solvent stripping fluid impingement on the nonwoven web, which removed additional residual solvent. The amount of residual solvent removed is strongly dependent on the temperature of the solvent stripping fluid.
