Use of modern methods of fibre surface modification to obtain the multifunctional properties of textile materials

Abstract

The modern textile fibre treatments aim to obtain the required level of beneficial effect while attempting to confine the modification to the fibre surface. Recently, much attention has been focused on different physical methods of fibre surface modification, cold plasma treatment being considered as very useful. Moreover, there are efficient chemical methods available, such as peroxide, biopolymer and enzyme treatment. Some interesting combinations of these physical and chemical surface modification methods as means to modify fibre surface topography and thus controlling the surface-related properties of the fibre are presented in this paper. The properties obtained are discussed on the basis of the physico-chemical changes in the surface layer of the fibre, being assessed by wettability and contact angle measurements, as well as by FTIR-ATR and XPS analysis. The SEM and AFM technique are used to assess the changes in the fibre surface topography and to correlate these changes to the effectiveness, uniformity and severity of the textile fibre surface modification treatments

Environmental impact of plasma application to textiles

“…Increase in wettability and swelling after plasma treatments significantly affect the dyeing and printing properties of wool [18][19][20][21][22]. The dye-exhaustion curves of untreated, chlorinated and [13,21].…”

“…Apparently, plasma treatment induced considerable increase in dyeing rate and final dye exhaustion. The longer the plasma treatment time, the higher the final exhaustion in case of acid dye [17,[21][22]. However, prolongation of plasma treatment time in case of direct dye demonstrated no significant influence on the dye exhaustion and obviously dye-exhaustion curves overlapped.…”
