In the realm of environmental protection and sustainable development, polylactic acid (PLA) materials have garnered significant attention due to their biodegradability. Moreover, PLA is more widely used in clothing home textile industries. However, application industry constrained by hydrolysis issues during conventional aqueous dyeing processes. This paper investigates a waterless technique utilizing linear silicone (LS) as nonaqueous medium. Because fibers are dyed environment, breaking strength fabrics LS system increased 4% 10%, elongation improved 7% 20% at temperatures 110 120 °C. it showed reduction 23.4% °C water-bathed dyeing. The facilitates high-temperature fibers, ensuring that remain intact below 140 contrast, when subjected traditional water bath °C, exhibit breakage. concerns mitigated bath, resulting enhanced thermal stability mechanical properties compared system. At equivalent temperatures, K/S value fabric can be small dosage acetic employed while color fastness washing, rubbing, light uninfluenced. selected medium recycled reused, which not only significantly improves resource utilization efficiency process but also effectively reduces generation emission waste. study provides promising approach for fiber, facilitating practical marking an important milestone toward sustainability industry.

Synthetic and natural fibers are widely used in the textile industry. Natural include cellulose-based materials like cotton, regenerated viscose as well protein-based such silk wool. fibers, on other hand, PET polyamides (like nylon). Due to significant differences their chemistry, distinct dyeing processes required, each generating specific waste. For example, cellulose exhibit chemical inertness toward dyes, necessitating auxiliaries that contribute wastewater contamination, whereas synthetic a major source of non-biodegradable microplastic emissions. Addressing environmental impact fiber processing requires deep molecular-level understanding enable informed decision-making. This manuscript emphasizes potential solutions, particularly through biodegradation related waste, aligning with United Nations Sustainable Development Goal 6, which promotes clean water sanitation. instance, cost-effective methods using enzymes or microbes can aid associated solutions while also addressing wastewater, contains high concentrations unreacted salts, highly water-soluble pollutants. paper covers different aspects dyeing, degradation mechanisms, waste produced by industry, highlighting microbial-based strategies for mitigation. The integration not only offers solution managing large volumes but paves way sustainable technologies.
