Argon Plasma Treatment for Improving the Physical Properties of Crosslinked Cotton Fabrics with Dimethyloldihydroxyethyleneurea-Acrylic Acid

Abstract

Low-temperature plasma has been widely used to modify the surface of metals, polymer films, and fabrics [1,2]. It is known that plasma treatment is an effective method for changing the surface properties of fiber and fabrics [3]. Plasma treatment could increase the reactivity of the fiber surface to improve the effect of grafting polymerization. Ward et al. [4] showed that using plasma before crosslinking agent treatment (plasma treatment and then pad-dry-cure treatment) could increase the dry wrinkle recovery angle of the finished cotton fabrics. Zubaidi et al. [5] pointed out that the breaking strength of finished cotton yarns could be enhanced by pre-treating the cotton yarn with plasma and then grafting with 2-hydroxyethyl methacrylate. Other studAbstract In this study, argon plasma treatment was added to the traditional pad-dry-cure process between dry and cure treatment. This new process was assign as pad-dry-plasma-cure. The crosslinking agent was a mixture of dimethyloldihydroxyethyleneurea (DMDHEU) and acrylic acid (AA). The results showed that argon plasma treatment could increase the bonded crosslinking agent (nitrogen content). Dry crease recovery angle (DCRA), wet crease recovery angle (WCRA) and tensile strength retention (TSR) of pad-dry-plasma-curefinished fabrics were higher than that of traditional pad-dry-cure finished fabrics at a given value of nitrogen content. Additionally, it was found that the number of crosslinks per anhydroglucose unit (CL/AGU) and the length of crosslinks of pad-dry-plasma-cure-finished fabrics were higher than that of traditional pad-dry-curefinished fabrics at a same resin concentration in the pad bath. DCRA, WCRA and TSR values of paddry-plasma-cure-finished fabrics were higher than that of pad-dry-cure-finished fabrics at a same CL/AGU value. The pad-dry-plasma-cure process is thought to be excellent for improving the physical properties and decreasing the formaldehyde release of the finished cotton fabrics.

In situ atmospheric pressure plasma treatment of cotton with monocarboxylic acids to impart crease-resistant functionality

“…However, these use strong catalysts and high temperatures during the pad-dry-cure process, which affect the mechanical properties (both tensile and tearing strength) of cotton fabric (Gagliardi and Shippee 1963;Qi et al 2016). In some studies, the use of plasma pretreatment in addition to the wet pad-dry-cure process has been explored in an attempt to reduce the undesirable effects of the above finishes (Chen et al 2010;Lam et al 2011a, b). However, the possibility of using in situ plasma reactions to impart crease-resistant properties in a single step has not been investigated.…”

Cell Proliferation of HaCaT Keratinocytes on Collagen Films Modified by Argon Plasma Treatment

“…Noble gases-based plasma treatment has widely been used in a diversity of applications, e.g., surface modification of polymers [ 11 , 12 , 13 , 14 , 15 , 16 , 17 ], glass [ 18 ], carbon fibres [ 19 ], superconductors [ 20 ], metal and alloys [ 21 , 22 ], and textiles [ 23 , 24 , 25 , 26 ]. As for medical uses, there are several studies conducted on cleaning surfaces [ 27 , 28 , 29 ] and cell attachment [ 30 , 31 , 32 , 33 , 34 , 35 ].…”

Mechanical and Surface Characterization of Sisal Fiber (Agave Sisalana) After Cold Glow Discharge Oxygen Plasma Treatment

“…Argon plasma treatment signi cantly increased tensile properties as well as the percentage of elongation. [25]The application of cold glow discharge oxygen treatment on sisal bers was investigated in this study. Unidirectional Sisal bers had been surface treated with cold glow discharge plasma oxygen throughout this research, as well as the impact on mechanical properties would always be investigated.…”
