Water Efficient, eco-friendly and Effluent Free Nano bubble Finishing of Cotton Fabric

ABSTRACT

Existing textile exhaust finishing methods require higher liquor ratios, such as 1:5 and 1:10, leading to energy wastage, chemicals wastage, and higher effluents. However, the nanobubble technique can reduce the liquor ratio to 1:1, resulting in water savings, energy savings, and zero liquid discharge. Nevertheless, production of the nanobubbles for a range of finishes and their successful application onto the textile is a difficult and challenging task. For the first time, this article successfully reports the development and application of nanobubbles at the extremely low liquor ratio of 1:1 for the five most commonly used textile finishes, which include resin, softener, soil release, oil and water repellent, and antimicrobial finishes onto the cotton fabric. In addition, this research compares the performance of the nanobubble finishing at a liquor ratio of 1:1 with higher liquor ratios of 1:5 and 1:10 for all five finishes. The results showed that optimized nanobubble finishing exhibited comparable key performance with reference to liquor ratios of 1:5 and 1:10 related to each finish category. However, the physical properties of cotton fabrics, such as tensile strength, tear strength, bending length, and air permeability, were better for nanobubble technology as compared to conventional finishing.

摘要

现有的纺织品排气整理方法需要更高的液比, 如1:5和1:10, 导致能源浪费、化学品浪费和更高的废水. 然而, 纳米气泡技术可以将液体比降低到1:1, 从而节省水、能源, 实现液体零排放. 然而, 用于各种整理剂的纳米气泡的生产及其在纺织品上的成功应用是一项艰巨而富有挑战性的任务. 本文首次成功地报道了纳米气泡在极低液比 (1:1) 下的开发和应用, 用于五种最常用的织物整理, 包括树脂、柔软剂、土壤释放剂、拒油拒水剂和抗菌整理. 此外, 本研究还比较了五种油剂在液比为1:1、液比为1:5和1:10时纳米气泡油剂的性能. 结果表明, 优化后的纳米气泡整理在每种整理类型的液比为1:5和1:10时, 表现出可比的关键性能. 然而, 与传统整理相比, 纳米气泡技术对棉织物的拉伸强度、撕裂强度、弯曲长度和透气性等物理性能有更好的改善.
