“…The utilization of biodegradable materials (mangrove bark as dyes, bee wax, enzyme, and aloe vera as finishing agents), less harmful chemical agents (H2O2/O3 instead of chlorine bleaching agents) in the textile production process will reduce the detrimental impact of wastewater effluents. Such an approach marks the prevention of harmful waste generation [59][60][61][62]. Aside from previously mentioned treatments, textile wastewater could yield value-added products such as biogas and biohydrogen.…”

In the last 30 years, global consumption of textile articles has increased significantly. Population increase along with the booming of fast fashion trends are facilitating the growth of global textile consumption. The current pandemic situation is raising the consumption of protective clothing. Such scenarios are diminishing the lifecycle of textile products significantly. Consequently, the world has observed a considerable increase in textile waste generation in recent years and is predicted to increase even more in the coming years due to the current consumption trends. Despite being highly recyclable, much of such wastes go into open dumps or landfills. The U.S. has also seen an increase in textile waste generation, and most of the wastes is landfilled. Disposing of such a huge waste stream can be identified as mismanagement due to its impact on the environment, society, and corresponding footprints. To counter the impact of the rising textile wastages, it is necessary to address sustainable approaches via a structured textile waste management system. This review aims to observe the textile waste scenarios based on the U.S.’s perspectives. An overall aspect of textile waste generation has been presented briefly while considering the current circumstances in the U.S. Current trends of textile waste management in the U.S. have been discussed while mentioning other available options in waste management. Lastly, this review has proposed some probable study directions that would facilitate establishing efficient textile waste management across the U.S.

“…A total of 20 experiments, including 2 3 = 8 factorial points, axial points and 6 center points, were performed five times each, and the average values of color strength were recorded as in Table V. The optimum values of the selected process variables were obtained by solving the regression model equation developed as follows (Bedin et al, 2017;Montgomery, 2012;Sinha et al, 2012;Sinha et al, 2013;Jabasingh et al, 2016):…”

“…Myrobalan, pomegranate and catechu has also been proposed to be used as bio-mordant in application of natural dyes. The former is obtained from fruits of the plant Terminalia chebula L. and is a rich source of tannins (Shabbir et al, 2016;Jabasingh et al, 2016). It also has a high content of ÀOH group (Shabbir et al, 2016).…”

Purpose This paper aims to investigate the feasibility of developing an eco-friendly dyeing process for a regenerated polyester fiber (polytrimethylene terephthalate) using a natural dye (Lac) and bio-mordant. Design/methodology/approach The effects of temperature, time, initial pH of dye bath, material to liquor ratio and mordant concentration on color strength of polytrimethylene terephthalate fiber dyed with Lac were examined. The results were compared using three bio-mordant (catechu, myrobalan and pomegranate) and three inorganic mordant (alum, ferrous sulfate and stannous chloride). Single replicate of 25-design methodology was used to identify three significant factors affecting color strength, and optimization was done using response surface methodology based on 23-central composite rotatable design. Findings Color strength achieved using catechu as a bio-mordant was close to that with ferrous sulfate and higher than with stannous chloride. Temperature, initial pH and mordant concentration were identified as significant factors affecting color strength of dyed fiber with catechu. Optimization revealed temperature of 133OC, initial pH of 6 and bio-mordant (Catechu) concentration of 10 per cent to be the optimal conditions for dyeing, with K/S value of 4.55. Originality/value The study revealed the possibility of satisfactory dyeing of regenerated polyester fibers with natural dyes, replacing disperse dyes. The comparison of color strength achieved indicated the possibility of replacing inorganic mordant with bio-mordant in such dyeing process. The dyeing process could thus be made more eco-friendly by removal of toxic chemicals from effluents.

“…These issues could be overwhelmed and substituted with curative and constructive approaches. For example, in recent years, the uses of biotechnology and nanotechnology have gained significant recognition, not only because of the progressive way of altering textile fibers but also have eco-friendly characteristics [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ]. The m-TGase bio-mordant [ 10 , 11 , 12 , 13 , 14 , 15 , 16 ] and nanoclay [ 17 ] are also the best candidates in the textile industry due to their favorable environmentally friendly properties.…”

Recently, natural dyes have a widening scope in various traditional and advanced applications due to their eco-friendly environment. However, improved dyeability of natural dyes still remains a challenging task. This research was aimed to achieve multi-objective wool with improved dyeability using bio-nano-mordant composed of m-Trans-glutaminase, m-TGase, and bentonite nanoclay. Wool fiber was treated through sonochemical method using different concentrations of m-TGase and bentonite. The surface morphology of wool fabric samples was examined by field emission-scanning electron microscopy (FESEM), and Fourier transform Infrared Radiation (FTIR). Further, wool samples treated at different conditions were applied to madder for dyeability examination. The optimum conditions of color coordinates, color strength, K/S, and washing fastness of madder on treated wool fabric with m-TGase and bentonite, were also examined. The results revealed well-made interactions among m-TGase, bentonite, and wool fibers. In addition, surface morphology was strongly influenced by variations in enzyme concentrations so that extra addition of m-TGase lead to clear damage scales or less cuticle surface in SEM images. Moreover, the results showed that the value of K/S for treated wool samples was better than untreated samples. Indeed, amongst all, 5% concentrations of bio-nano-mordant for m-TGase and bentonite have the most constructive K/S values. Similarly, results of Δ E and antibacterial investigations also confirmed its superiority.
