“…Textile industries are one of the largest generators of wastewater due to extensive volume of water is utilized in finishing and dyeing processes [6]. Other reports use technology to improve textile processes and reduce environmental pollutants [7,8]. It is predictable that, the liberalization of 10 -15% of dyes in the treated water [9], which affect the photosynthetic activities in aquatic life by reducing the intensity of light propagation that may also be lethal to some aquatic animals and plants due to the attendance of aromatic materials, metals, chlorides and because of high biochemical oxygen demand (BOD), COD and low biodegradability [10,11].…”

I N this study, fungal isolate D2-1 was isolated from contaminated soil collected from textile industry companies and showed high potentiality for decolorization of two different azo dyes. This isolate was identified as Aspergillus niger D2-1 using morphological and cultural characteristic as well ITS gene sequencing. Decolorization process under different optimized condition of azo dye concentration, pH, incubation periods, inoculum size and different carbon and nitrogen sources were investigated. The maximum decolorization efficiency against 100 ppm dye concentration of reactive yellow (4GL) and reactive red (4BL) dyes of 98.62 %and 92.42 %, respectively, were recorded for Aspergillus niger D2-1 at pH 9.0, in presence of 2 % glucose and 0.5% yeast extract as carbon and nitrogen sources respectively at room temperature after 7 days on shaking conditions. The decolorization percentage was confirmed by ultraviolet-visible (UV-Vis) spectrum analysis of untreated/treated reactive yellow (4GL) and reactive red (4BL) dyes, which showed complete disappearance of peaks at ~ 425 nm and at ~ 520 nm, indicates the degradation of dyes due to fungal activity. Treatment of textile wastewater effluent by Aspergillus niger D2-1showed high decolorization percentage (59%) for effluent, also physico-chemical characteristics of textile effluent such as chemical oxygen demand (COD), total dissolved solids(TDS) and total suspended solids (TSS) were decreased from 756 mg/L, 1597 mg/Land 821 mg/L to 391 mg/L, 845 mg/L and 362 mg/L respectively. Moreover, Gas chromatography-mass spectroscopy (GC-MS) of textile effluent before and after treatment were recorded and confirmed the potentiality of Aspergillus niger D2-1 in dyes wastewater treatment.

“…Most importantly, regarding the safety issue, the materials safety data sheet (MSDS) provided a clear idea about the presence of non-hazardous elements in the used chemicals. Several studies were carried out to improve multifunctional properties of textile fabric [ 31 ]. Some studies were conducted to make the fabric UV protective and attain antimicrobial property [ 32 , 33 , 34 ].…”

It has, nowadays, become indispensable to get multi-functional properties from a single piece of fabric or garment in the sector of textile and fashion. Cotton fabric is now extremely being utilized in garments all over the world. At the raw stage, cotton fabric has less reflectance, high ignition tendency, moreover the proclivity to be attracted by microorganisms. The strength of the fabric might be deteriorated because of frequent processing. In this study, a single jersey raw (grey) cotton fabric of 150 GSM was processed with a pertinent chemical treatment to convert the reflectance to about 100 % and impart flame resistance property together with the other functional properties. Due to the attainment of high reflectance and flame resistance traits, the heat-absorbing tendency of the fabric became low which improved the comfortability of the fabric. The strength of the processed fabric was increased by 4 %. Crease recovery angle was increased by 57 % in the course way and by 82 % in wales way direction that attributed crease-resistance and more stability to the modified fabric. Moreover, the processed fabric was also able to exhibit antimicrobial properties. Strength improvement, attainment of crease-resistance, and antimicrobial property could enhance the longevity of the fabric. The attainment of multifunctional properties together with the strength improvement simultaneously provided a unique feature to the modified cotton fabric. It was a permanent chemical treatment, and it modified the surface of the fabric, which ultimately enhanced the proclivity of cotton fabric to be more compact or crystalline and more stable. The addition of the new quality of the cotton fabric could endure even after washing. The modified cotton fabric with newly added characteristics could be a good choice to prepare garments with felicitous longevity to protect from heat, fire flame sensitivity. It really could create an opportunity in multi-functional fabric processing as well as modern textiles.

Textiles functionalized with cupric oxide (CuO) nanoparticles have become a promising option to prevent the spread of diseases due to their antimicrobial properties, which strongly depend on the structure and morphology of the nanoparticles and the method used for the functionalization process. This article presents a review of work focused on textiles functionalized with CuO nanoparticles, which were classified into two groups, namely, in situ and ex situ. Moreover, the analyzed bacterial strains, the resistance of the antimicrobial properties of textiles to washing processes, and their cytotoxicity were identified. Finally, the possible antimicrobial mechanisms that could develop in Gram-positive and Gram-negative bacteria were described.
