Purpose This work aims to increase the dyeability of nylon 6 with basic dyeing through the treatment of the fibre with available and cheap nanomaterials, namely; nano bentonite using an economic and simple method. Design/methodology/approach Different amounts of nano clay, namely, nano bentonite were dispersed in distilled water using an ultrasonic homogenizer for 1 h. Nylon fabrics were treated with different concentrations of dispersed nano bentonite (1%, 2%, 3%, 4%, 5% wt/v). After half an hour, the samples were padded using SVETEMA laboratory padding system. The padding pressure was adjusted at 3 bar to allow a pickup of 100%. The padded samples were dried at 80°C for 5 min and cured at 160°C for 3 min using ROACHES laboratory thermos-fixation. The cured samples were then washed with running water and left to dry at room temperature. Findings The obtained results indicated that the modification of polyamide 6 fibres with nano bentonite had a great impact on their dyeing properties. The obtained shades, absorption behaviour and fastness properties were significantly enhanced. Based on these results, it was concluded that polyamide fabrics could be successfully dyed with basic dyes using economical dyeing conditions. Originality/value This paper introduces a new method the loaded the nano-clay on the synthetic fibres, which are nylon 6 to enhance the dyeability with cationic dyes using the physical method without changing the structure of the fibres.

“…1–8 Atmospheric plasma techniques have also been investigated and used for surface modifications. 9–12 Many studies concerning the grafting of various vinyl monomers such as acrylic and methacrylic acids, methyl acrylate, acrylamide, and vinyl pyridine onto the polyester fabrics using different chemical initiators or electron beam pre-irradiation initiation have been published. 13–24 Since the traditional polyester fibers are dyed only with dispersion dyes, dyes that have lower extinction molecular coefficients and do not exhibit brilliant shades, a number of studies have been published concerning the dyeing of polyester with other classes of dyes.…”

3-chloro-2-hydroxypropyl acrylate obtained by the esterification of epichlorohydrin with acrylic acid in the presence of zirconium silicate as a catalyst was used for grafting of the polyester fabric in order to improve some of its properties. The grafting was performed in the presence of (NH 4) 2 S 2 O 8 as a polymerization initiator. The grafted samples were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, and energy-dispersive X-ray spectroscopy analyses. The effect of grafting on the comfort indices (hygroscopicity and vapor permeability) and the tinctorial properties (color intensity and dyeing fastness) were analyzed. Further addition of AgNO 3 in the final reaction mixture used for grafting of polyester fabric confers antibacterial effect to the treated samples. The properties of the polyester fabric were highly improved by grafting with 3-chloro-2-hydroxypropyl acrylate.

“…In recent years, low-temperature plasma generated by atmospheric pressure glow discharge (APGD) has been widely applied in materials processing, biomedicine and environmental science [1][2][3][4][5]. The plasma jet generated by APGD has the advantages of low temperature, strong chemical activity and high controllability [6][7][8][9][10].…”

Experimental studies of a larger-scale atmospheric pressure glow discharge (APGD) nitrogen plasma jet are presented in this paper. A chamber with non-uniform gap formed in the electrode structure is designed by using non-uniform thickness of dielectrics. Through the electric field simulation, it is found that there is a non-uniform electric field distribution in the lateral and longitudinal directions of the chamber. The discharge starts from the larger electric field intensity of the submillimeter and then is followed by the development to the left and right sides of the smaller electric field intensity of the long gap. Moreover, the non-uniform electric field distribution in the lateral and longitudinal directions can help to suppress the generation of filament discharge. The experiments indicate that a uniform APGD in nitrogen is formed in the chamber and the inner electrode surface has a large luminous intensity. Through the fluid simulation, it is found that the velocity of the gas at the inner electrode surface is large. As a result, the nitrogen flow can effectively bring out the high-density plasmas on the inner electrode surface, which is beneficial to the formation of the plasma jet. The experimental results show that the electrode structure can generate APGD nitrogen plasma jets with the length of 10 mm and width of 15 mm, which is of relatively high application value.
