Yarns as well as fabrics such as weaves or nonwovens are commonly postprocessed by many processes. A conventional method is fabric treatment by liquids which react on the fibre surface. The result of all chemical treatments of a fabric is designated finish. The effects of a finish are various:
- Colouring, stabilizing a weave, waterproofing, hydrophobing, UV-stabilisation, antistatic modification, anti-fungizide treatment and many else.
Many of these effects can be achieved by plasma treatment. Regarding the following processes Plasma treatment has signifcant benefits compared to conventional methods:
- Removing Coatings
- Activation prior to printing and laminating.
- Hydrophobing and oleophobing to provide waterrepelent and selfcleaing surfaces.
Textile treatment can be performed by atmospheric prressure plasma as well as by low pressure plasma. Atmospheric plasma allows for endless continuous treatment. Most particularly plasma coating processes which require longtime plasma reactions and process gases which cannot be applied under free Atmosphere can only be performed in a Low pressure process,
Diener electronic has developped systems which enable endless yarn trearment or roll-to-roll fabric treatment.
Plasma treatment in low pressure conditions much better treats all surfaces which are shadowed by other fibres
