Surface modification of polyester and polyamide fabrics by low frequency plasma polymerization of acrylic acid

Abstract

In this study, the surface characteristics of polyester and polyamide fabrics were changed by plasma polymerization technique utilizing acrylic acid as precursor. This monomer was used to produce hydrophilic materials with extended absorbency. The hydrophilicity, total wrinkle recovery angle (WRA8) and breaking strength of the fabrics were determined prior and after plasma polymerization treatment. The modification of surfaces was carried out at low pressure (<100 Pa) and low temperature (<508C) plasma conditions. The effects of exposure time and discharge power parameters were optimized by comparing properties of the fabrics before and after plasma polymerization treatments. It was shown that two sides of polyester fabric samples were treated equally and homogeneously in plasma reactor. For polyester fabrics, the minimum wetting time, 0.5 s, was observed at two plasma processing parameters of 10 W-45 min and 10 W-20 min, where untreated fabric has a wetting time of 6 s. For polyester fabrics, the maximum value was obtained at 60 W-5 min with the wrinkle recovery angle of 3068 where the untreated fabric has 2908. The optimum plasma conditions for polyamide fabrics were determined as 30 W-45 min where 2 s wetting time was observed. Wrinkle recovery angle of untreated polyamide fabric was 2648. In this study, after plasma polymerization of acrylic acid, wrinkle recovery angle values were increased by 13%. No significant change was observed in breaking strength of both fabrics after plasma treatment.

Effect of mechanical, barrier and adhesion properties on oxygen plasma surface modified PP

“…The atoms in the excited or fundamental states are holding a net neutral charge (Liu, Cui, Brown, & Meenan, 2005). To attain the surface modification characteristics of polymeric materials, the effective technology is the plasma treatment (Cireli, Kutlu, & Mutlu, 2007). The surface phenomena such as crosslinking, etching and activation are done by the interactions between surface molecules of polymers and plasma (Riccardi et al, 2003).…”

Tuning the Surface Properties of Oxygen-Rich and Nitrogen-Rich Plasma Polymers: Functional Groups and Surface Charge

“…Therefore an additional surface treatment applied to this particular branch of materials is often beneficial [9][10][11][12]. In this regard, modifying surfaces with plasma is considered as one of the most efficient methods through which surface adhesion can be enhanced either through functional group grafting or deposition of a new functional layer [13][14][15]. One frequently proposed plasma base strategy is the coating of a surface with organic macromolecules (plasma polymers) containing a desirable chemical composition and morphology which allows some control over the interactions of the surfaces with surrounding biomolecules and living cells while the bulk properties of the substrate remain largely intact [16][17][18].…”

Plasma-induced adhesion improvement of cotton/polypropylene-laminated fabrics

“…[33] For this reason, wettability of textile surface was determined by indirect methods such as wicking rate, [10,29,34,35] liquid absorption capacity, [36] and absorption time. [37,38] In this study, plasma treatment was applied only on the back side (laminated side) of cotton fabric samples. The front side of the cotton fabric samples had a hydrophobic resin coating, which prevented the vertical liquid rising.…”
