“…The plasma driven processes of inducing physical and chemical surface changes such as etching, grafting, implantation, polymerization, and crosslinking take place simultaneously. Several research groups have investigated enhancement in hydrophobicity of fabrics and polymers using plasmas of perfluorocarbons such as tetrafluoromethane (CF 4 ) [5], hexafluoropropylene (C 3 F 6 ) [6], and hexafluoroethane (C 2 F 6 ) [7]. Li and Jinjin [6] confirmed the presence of ÀCF, ÀCF 2 and ÀCF 3 groups on fabric surface treated with C 3 F 6 plasma.…”

Sun and Stylios [7] found that C 2 F 6 can produce polymers as result of the plasma treatment on the treated wool and cotton.…”

“…This technique allows quantifying quickly the chemical composition obtained promptly after plasma discharge application. However, EDS is not the most adequate technique to evaluate carbon content after plasma treatment, thus for a more accurate study of the surface modifications provoked by plasma species interaction, the XPS technique is the most commonly mentioned in the literature [36][37][38] and the results obtained with this important technique can be observed in table 5.…”

In this work, physical, chemical and morphological modifications of three different polyamide 6.6 (PA6.6) fabrics were investigated using double barrier dielectric (DBD) plasma treatment. Several techniques of characterization were used to study the effects caused by the interaction between plasma discharge and polyamide fabrics, such as: contact angle, water drop adsorption, Energy Dispersive Spectroscopy (EDS), X-ray Photoelectron Spectroscopy (XPS), Scanning Electron Microscopy (SEM), whiteness by Berger degree and tensile strength. All analyses performed in this study showed that DBD plasma discharge, when applied on PA6.6 fiber, produces significant modifications on the surface of this substrate, without altering its intrinsic properties, thus proving the effectiveness of this important technology to the textile industry.

“…For example, hydrophobicity enhancement of Thai silk using SF6 plasma has been successfully performed in an inductively coupled plasma discharged system [3,4]. Improvement of hydrophobic properties of Chinese silk and cotton by C3F6 plasma treatment has also been successfully performed [5]. A plasma induced graft polymerization was successfully utilized to coat silk fabrics with flame retardant material, followed by SF6 plasma treatment for water repellent finishing [6].…”

Abstract. A 13.56 MHz RF plasma discharge was successfully utilized to activate and coat Thai silk fabrics with chitosan for durable antibacterial property. Uncolored and untreated Thai silk fabrics were activated in Ar plasma for 5 minutes with an optimized RF power of 120 W under Ar pressure of 0.8 Torr. After plasma activation, specimens were submerged and stirred in a 1% (w/v) chitosan solution. FTIR analysis confirmed the presence of chitosan on the silk fabrics. From SEM analysis, chitosan was observed to coat silk fibers almost everywhere. RF plasma treated fabrics were able to absorb the chitosan solution substantially faster than those without the treatment. Another benefit of increased hydrophilicity is the ability of the treated fabrics to allow human perspiration to flow through more effectively, providing additional comfort when worn in tropical-zone countries. Antibacterial properties against E. coli and S. aureus reduced with increasing washing cycles dropping to approximately 95% after 5 rounds of washing. Extrapolation of linear trend lines revealed that for the case of E. coli, it will take approximately 16 washing cycles to reduce the antibacterial ability to 90%. For the case of S. aureus, it will take approximately 10 washing cycles to reduce the antibacterial ability to 90%. Fabrics without RF plasma treatment prior to chitosan solution submersion will have their antibacterial ability for E. coli and S. aureus reduced to 90% after only about 5 washing cycles. Thus, RF plasma treatment can effectively induce chitosan to provide a strong and durable coating for Thai silk fabrics, thus, offering a new, very environmentally-friendly coating technique for Thai silk with chitosan for potential use in the textile industry.
