Hydrophylisation of non-woven polypropylene textiles using atmospheric pressure surface barrier discharge

Journal of Optoelectronics and Advanced Materials 10 (2008) 213-218

The aim of the present work was to investigate the surface modification of non-woven polypropylene textiles by means of plasma treatment at atmospheric pressure in order to improve their hydrophilic properties. The polypropylene non-woven spun-bond textiles with surface weight of 20 g/m(2) were used as the samples. The surface activation was provided by surface barrier discharge at atmospheric pressure where the operation frequency was 6 kHz. The surface energy of treated and untreated textile was investigated by means of contact angle measurement with four different liquids using the Surface Energy Evaluation System (SEE System). The surface energy was calculated according to LW/AB theory. The surface energy was correlated to the wetting properties of the materials studied by industrial permeability tests. In the present paper the hydrophilic properties and aging of plasma treated polypropylene samples with the plasma conditions and Plasma exposition time are discussed.
