摘　　要：随着生活水平的提高,人们对服装的舒适度愈发重视,碱减量技术在改善涤纶织物的手感方面有着广泛应用,然而涤纶碱减量技术也有着许多缺点。针对涤纶碱减量技术存在的问题,结合碱减量技术的原理以及目前清洁生产的发展背景,着重介绍了利用促进剂提高涤纶碱减量效果的方法,并分析了促进剂的作用机制,基于使用促进剂的优缺点,指出未来促进剂的发展方向,提出碱减量与涤纶染色一浴进行是精炼涤纶染整加工流程、提高生产效率的有效方法,以期对纺织行业的可持续发展提供指导。Polyester fiber is currently the most widely used synthetic fiber.However,its poor moisture absorption,susceptibility to static electricity,and other issues have hindered its market prospects as a high-end textile material.Alkali reduction treatment can improve the inherent defects of polyester fiber,resulting in a soft and smooth texture,a pleasant sheen,good drapability,water retention,and other advantages.Meanwhile,this treatment makes it has the characteristics of imitated silk.Nevertheless,the traditional alkali reduction process for polyester involves excessive use of alkali,making it difficult to process.Finally,it requires a large amount of acid to neutralize.As a result,there are many problems,such as high energy consumption,serious environmental pollution,and serious damage to the fabric.Additionally,the liquid alkali is also a dangerous chemical,so safety problems should be considered.All these problems seriously restrict the sustainable development of the polyester textile industry.Therefore,reducing the amount of liquid alkali with promoters is currently the most convenient,environmentally friendly,and easily implementable improvement method in the alkali reduction technology.Currently,promoters are widely used to improve alkali utilization,reduce the environmental hazards of excessive alkali,and impart exceptional performance to fabrics.Promoters can be roughly categorized into quaternary ammonium salts,gelatin protein promoters,cationic polymers,ionic liquids,amines,alcohols,and others.Among them,quaternary ammonium salts are widely used.In terms of effectiveness,most promoters can accelerate the hydrolysis of polyester and reduce the amount of alkali required.And different promoters have different promotion mechanisms.Quaternary ammonium cationic surfactants mainly utilize positively charged quaternary ammonium ions to attack the carbonyl carbon atoms by carrying the hydroxide ions,further promoting the rapid hydrolysis of ester bonds in polyester macromolecules.Gelatin has certain surface activit
