“…Cotton fabric is a type of natural porous fabric with good wearing properties, such as moisture absorption, breathability, and skin-friendliness [1,2]. However, cotton fabrics have problems such as being easy to wet, easy to stain with oil, and easy to wrinkle, and with poor UV resistance performance.…”

To explore the combination of silver nanoparticles (Ag NPs) prepared in a green manner with cotton fabrics and the washing durability of the fabric after the combination. In this paper, the natural material, honeysuckle extract, was used as a reducing agent to prepare the Ag NPs’ solution. The structure and size of Ag NPs were analyzed using ultraviolet–visible spectrophotometry (UV–vis), transmission electron microscopy (TEM), dynamic light scattering (DLS), X-ray powder diffraction (XRD), and Fourier transform infrared (FT-IR) spectroscopy characterization. The results showed that Ag+ was successfully reduced to Ag0 by the honeysuckle extract, the particle size was about 10.59 nm, and the potential was −42.9 mV, so it had strong electrostatic repulsion and good stability. Meanwhile, it was found that the synthesized Ag NPs were well coated by the honeysuckle extract, so they would not aggregate. Then, the cotton fabric was finished with Ag NPs’ solution by the dipping method using a complex of polymaleic acid (PMA) and citric acid (CA) as a cross-linking agent to fix Ag NPs on the cotton fabric. The structures of cotton fabrics before and after finishing were characterized using FT-IR, scanning electron microscopy (SEM), XRD, X-ray photoelectron spectroscopy (XPS), and thermogravimetric (TG) analysis, and the multifunctional properties of the finished cotton fabrics were explored by measuring the antibacterial rate, the wrinkle recovery angle (WRA), and the UV protection factor (UPF) value. The results show that Ag NPs were successfully loaded onto cotton fabric, and the PMA + CA compound was successfully cross-linked to the fabric. The cross-linked Ag NPs’ cotton fiber was rougher than that before cross-linking, and its TG stability improved. The PMA + CA compound fixed Ag NPs on the cotton fabric through chemical bonds, so it still had a 99% antibacterial effect against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) after 50 washings. Compared with unfinished cotton fabric, the UPF value and WRA of the cross-linked Ag NPs cotton increased by 34.09 and 98°, respectively, and its color did not change much.

“…2,3 Reactive dyeing is one of the main pollution causes. 4 In the conventional water-based textile reactive dyeing process, a huge amount of inorganic electrolyte, alkali and unsettled dye is drained to dyeing wastewater [5][6][7][8] which increases the pollution load and that is nearly unavoidable. [9][10][11] In order to reuse the wastewater from dyeing industries and reducing water pollution, treatment of effluent and recycling of wastewater plays an important role.…”

The replacement of inorganic salt and alkali in the reactive dyeing of cotton textiles with organic biodegradable compound has been explored in recent years. We report the use of organic salt, tetra sodium salt of glutamic acid diacetic acid (GLDA-Na 4 ) in the batchwise dyeing of cotton garment as an exhausting and fixing agent. The reactive dye, CI Reactive Black 5 was selected for the present study. The results revealed that the maximum K/S value of 25.5 and fixation of 90.74% was obtained using GLDA-Na 4 at laboratory scale experiments. Furthermore, the effluent samples test results demonstrated considerably reduced total dissolved solids (TDS) and chemical oxygen demand (COD) contents with GLDA-Na 4 in comparison to the inorganic chemicals. The colourfastness to light, rubbing and washing have demonstrated similar ratings with GLDA-Na 4 and inorganic chemicals. The tensile strength of samples was enhanced by using GLDA-Na 4 .

“…Accordingly, indisputably one of the biggest problems in dyeing is water and energy consumption. 32,[38][39][40] In the literature, there are many articles on water saving, 41,42 reducing the use of chemicals, 43,44 treating wastewater with different methods and removing color in wastewater, [45][46][47] etc., within the scope of environmental production in many areas of textile. However, there are hardly any studies on the use of nanobubbles, a new technology, in the development of environmentally friendly textile processes.…”

In this study, we used the new nanobubbles technology to create a green reactive washing process for the textile industry, as one of the most polluting sectors where environmentally friendly process designs are indispensable to protect the environment. With this technology, the possibility of eliminating the soaping-off step from the reactive washing sequence was investigated. For the design of an environmentally friendly reactive washing process, the effects of increasing the process temperature of the soaping-off step as well as the use of oxygen-enriched NBs in all washing steps after reactive dyeing with three different dyes were investigated. The results were evaluated by comparing the color coordinates, strength, and fastness of dyed cotton towels washed according to the conventional and alternative processes as well as examining the absorbance and chemical oxygen demand values of the washing baths. Alternative washings did not cause significant differences in color coordinates, while the lowest color strength and highest fastness values were obtained after washing with nanobubbles. The absorbance graphs showed that the most colorful baths belonged to the first bath of the nanobubble washing regime. Chemical oxygen demand measurements revealed that the alternative washing systems were more environmentally friendly than the conventional ones. Based on the results of this study, we concluded that it was possible to implement more eco-friendly washing methods by eliminating the use of soap.
