ABSTRACT: -
Non-ionic surfactants have emerged as crucial agents in textile production because of their unique physicochemical characteristics, such as neutrality, low toxicity, and good compatibility with various chemicals and fibres. Their amphiphilic nature allows them to wet, emulsify, disperse, and stabilize well, making them suitable for application at different stages of textile processing especially in pre-treatment, dyeing, and finishing. This review discusses the structural diversity of non-ionic surfactants and examines their functionality in enhancing fabric quality, dye uniformity, process efficiency, and environmental compliance. Individual surfactant types like alcohol ethoxylates, fatty acid ethoxylates, sugar-based surfactants, and block copolymers are explored for their individual contributions to textile treatment. In addition, the paper discusses new developments such as bio-based surfactants, thermos responsive materials, and nanostructured finishes that broaden the application of non-ionic surfactants in smart textiles and green manufacturing. Environmental factors such as biodegradability, aquatic toxicity, and regulatory limitations are also discussed. By summarizing available literature and emphasizing new trends, the review of this article should present an integral view of the mechanism, advantage, and future outlook of non-ionic surfactants in contemporary textile production. The extended progress of non-ionic surfactants will be crucial to address the requirements of the industry for high performance, sustainability, and process innovation.
