Modern textile dyeing and printing pretreatment auxiliaries are evolving toward greater efficiency, eco-friendliness, and multifunctional integration. Traditional processes often rely on high-alkali and high-temperature treatments-methods characterized by high energy consumption and significant potential for fiber damage. In contrast, novel auxiliaries leverage compounding technologies to enable low-temperature, low-alkali, or even alkali-free treatments, thereby significantly reducing energy consumption and wastewater discharge. For instance, enzymatic scouring agents can serve as substitutes for certain chemical reagents, efficiently removing impurities under mild conditions while offering dual benefits in terms of environmental protection and energy conservation. Furthermore, the multifunctionality of these auxiliaries is becoming increasingly prominent; for example, composite auxiliaries that combine penetrating, scouring, and chelating capabilities help streamline process workflows and boost production efficiency.
As environmental regulations become increasingly stringent and the philosophy of sustainable development gains deeper traction, the "greening" of dyeing and printing pretreatment auxiliaries has emerged as a core strategic direction for the industry. The development of eco-friendly auxiliaries-specifically those that are low in toxicity, biodegradable, and free from harmful substances such as APEOs-has become a mainstream trend. Concurrently, the advent of digitized and intelligent manufacturing systems places higher demands on the stability, reproducibility, and adaptability of these auxiliaries, thereby driving the continuous optimization of their formulations. Moreover, research and development efforts are steadily advancing to create specialized auxiliaries tailored to the unique pretreatment requirements of novel fibers, such as regenerated cellulose fibers and high-performance fibers.
