Abstract A sustainable solution to lessen environmental damage, improve health and fulfill the increasing need for environmentally conscious goods might be textile industry use eco‐friendly printing techniques natural colors. Without of toxic metal‐based mordants, this research work set out examine how thickeners, biomordants, dyes interacted when printed on cotton knit fabric. Two from resources leaves Jujube (JL) Eucalyptus bark (EB) were extracted in an aqueous medium. paste was produced using different proportions two bio‐mordants. For process, tamarind seeds, Indian gooseberries used that have been a Soxhlet apparatus at 80°C 8 h. All but handful samples binders showed outstanding fastness sample which graded 4 or 5. The development dye‐fiber bond indicated by presence intense covalent between dye fiber molecules as FTIR. CMC lab data K/S value also obtained satisfactorily with maximum RFL 77.319 K/s 1.659. This method not only lessens impact sector supports better more ecologically sensitive manufacturing technique. Moreover, apparel, household textiles, technical fabrics, friendly packaging can all benefit bio‐colorants bio‐crosslinkers. Highlights Eco‐friendly jujube eucalyptus reduces harm. Bio‐mordants seeds gooseberry effectively replace harmful mordants. Printed show excellent ratings 4–5, proving quality printing.

As textile production continues to grow worldwide, managing the mounting waste generated by this industry is becoming an urgent environmental concern. Globally, over 92 million tons of are produced annually, much which incinerated or disposed in landfills, contributing greenhouse gas emissions, soil and water contamination, ecosystem harm. This review explores how chemical biotechnological methods, such as acid hydrolysis (achieving up 70% glucose recovery) enzymatic recycling (reducing energy consumption approximately 20% compared conventional methods), can transform into valuable resources, fostering a shift toward circular economy that minimizes reliance on virgin materials. However, diverse nature waste─particularly mixed fibers materials treated with various finishes additives─adds complexity processes, often necessitating specific pretreatment steps ensure both efficiency economic viability. Scalable solutions advanced solvent recovery systems, optimized techniques, fluidized-bed pyrolysis (which increase bio-oil yields 25% fixed-bed reactors) play crucial roles making more sustainable adaptable at industrial scale. By addressing these technical financial challenges, improve sustainability practices, reducing resilience. also suggests several future directions enhance scalability compatibility goals, highlighting potential for technologies create secondary support greener practices management. Through continued innovation commitment better balance resource feasibility, unlocking substantial opportunities mitigate impact resource-efficient, future.

Abstract The influence of the textile industry on environment, as well usage raw materials and natural resources, is becoming a major problem. It no longer sufficient to have product that simply safe for humans; must also be ecologically throughout its entire life cycle. As result, there has been shift toward employing enzymes in sector promote eco-friendly production. goal this research create an environmentally friendly discharge printing cotton wool textiles, dyed with various plant extracts (Ficus benjamina, Psidium guajava leaves, Solanum melongena peel, Brassica oleracea var. capitata rubra) under varied circumstances by using polyphenol oxidase (PPO) peroxidase (POD) extracted from taro corms (Colocasia antiquorum) instead harmful reducing or oxidizing agents. enzyme extraction temperature was 25°C, solute-liquid ratio (1:4 (w/v)) at pH 5.0 after treatment time 5 min. oxidative were analyzed Gas Chromatography-Mass Spectrometer (GC-MS) Analysis, which verified presence Retinol component molecular weight 286.45 g/mol retention 14.7 min, regarded proof existence enzymes. activity isolated increases over time, PPO having highest 180 seconds wavelength 420 nm.

ABSTRACT Bacterial biofilms are complex, multi‐component structures consisting primarily of four key elements: polysaccharides, metal ions, proteins, and extracellular DNA. In our research, we specifically focus on the polysaccharide ion components, which play a crucial role in determining biofilm's mechanical properties. Polysaccharides provide structural matrix, although particularly divalent cations like calcium cobalt, cross‐link with thereby modulating rigidity viscoelastic behavior. By introducing into nanocellulose, can replicate this natural cross‐linking process, allowing us to finely tune material's properties more closely resemble those bacterial biofilms. This approach not only enhances accuracy synthetic biofilm models over alginate hydrogels but also provides valuable insights how maintain their integrity various environments. Our findings indicate that nanocellulose exhibits closer than analogs, making it suitable non‐living control for studies. Furthermore, nickel, followed by magnesium, demonstrate mimicry conclusion, research shows potential as versatile material mimicry.

Disperse dyes, primarily used for dyeing synthetic fibres like polyester, are characterized by their poor solubility in water, which necessitates the use of dispersing agents; however, environmental concerns arise due to low biodegradability and potential toxicity, thus posing significant challenges waste management pollution control. This study explores performance knitted polyester with dispersed employing natural auxiliaries as substitutes conventional commercial chemicals promote an environmentally friendly approach. Citric acid (derived from lemon), sodium citrate (prepared citric bicarbonate), glucose (extracted date fruits) replace acetic acid, agent, hydrolyze. Dyeing is conducted using high-temperature high-pressure methods consistent parameters. A comparative existing was assessed concerning colour strength, different fastness properties, FT-IR diagram. Proton NMR utilized structural determination fruit lemon components. UV-Vis spectral data show that adding dye solution drops absorbance value 1.1457 0.58916, confirming citrate's efficacy a agent.
