Abstract
This paper describes the development of a plasma process to produce a durable water repellent and anti-stain thin film on synthetic textile, utilized for the upholstery in the automotive field. The coatings were deposited in non equilibrium low pressure plasmas fed with 1H, 1H, 2H-perfluo-ro- 1-decene employing, as substrates, polyethylene terephthalate and polyethylene terephthalate thermo-coupled to polyurethane foam. It was found that the XPS F/C ratio of the deposit was higher than 1.4 and that the treated textile was always very hydrophobic (WCA > 140˚) and oil re- sistant (motor oil CA > 110˚), even after wear.
Highlights
Introduction[1]-[6], are becoming always and more important
The finishing processes of textiles devoted to improving the quality of the fabric and impart specific properties, such as hydrophobicity, hydrophilicity, anti-bacterical, flame retardant, shrink resistance, etc. [1]-[6], are becoming always and more important.Both chemical and physical methods are generally used to obtain specific properties
The upper electrode was connected to a 13.56 MHz radio frequency (RF) power supply though an automatic L-type matching network unit, while, the lower electrode, on which the textile samples were positioned during the deposition processes, was grounded
Summary
[1]-[6], are becoming always and more important Both chemical and physical methods are generally used to obtain specific properties. The utilization of low pressure plasma processes, in particular, has been widely investigated for the modification of surface properties of textile composed by synthetic polymers and natural materials [1] [2] [8]. The surface modifications and properties depend on the feeding gas and on the operating conditions (input power, pressure, electrode geometry, etc.); a proper selection of these parameters allows to obtain different processes with the same experimental apparatus, i.e. etching, grafting, cross-linking and deposition [2]
