The effect of low-temperature plasma pretreatment on wool printing
(Amer Assoc Textile Chemists Colorists-Aatcc, Res Triangle Pk, 2000)
The application of radio-frequency capacitively coupled plasma for the treatment of wool was studied. The influence of plasma parameters on the printing and mechanical properties of wool was determined. Results after plasma ...
Surface characterization of keratin fibres treated by water vapour plasma
(Wiley, Hoboken, 2003)
The effect of water vapour plasma treatment on the shrinkage behaviour and chemical properties of the surface of keratin fibres was studied. The wettability and shrink resistance of wool were improved even at low plasma ...
Acceptability of Residual Stresses Measurement Methods of Butt Weldments and Repairs
(Strojarstvo, 2009)
The joints made by fusion of materials are exposed to the influence of residual stresses induced by welding thermal cycles. Residual stresses were measured on butt welded plates made of NIOMOL 490K, before and after ...
