Comparing plasma and laser treatments of textile surfaces

5 Comparing plasma and laser treatments of textile surfaces 

Wong et al. (2000) used a pulsed UV (KrF) excimer laser and an oxygen gas discharge LTP to modify the surface structure of PET fibres. Although both plasma and laser-treated fibres exhibit similar ripple/roU-Uke structure surfaces, the morphological modifications are not identical, as shown in Rg. 2.17.The PET fibres were firstly treated by LTP (100 W,5 Pa, 10 min) and then by laser irradiation under different fluence and pulses. It was found that the threshold for the formation of a ripple-like structure under laser irradiation was lower for PET with LTP pre-treatment (see Rg. 2.17). In addition.

Improvement of the surface characteristics of textiles is required to meet economic, market and environmental needs. Textile products that require
