This study establishes an eco-friendly anti-wrinkle treating process for cotton fabric. Sodium hydroxide-liquid ammonia pretreatment followed by 6% (w/w) PU100 adding citric acid pad-cure-dry finishing. In this process, citric acid (CA) was used as the fundamental crosslinking agent during finishing because it is a non-formaldehyde based, cost-effective and well wrinkle resistance agent. Environmental-friendly waterborne polyurethane (WPU) was used as an additive to add to the CA finishing solution. Six commercial WPUs were systematically investigated. Fabric properties like wrinkle resistance, tensile strength retention, whiteness, durable press, softness, and wettability were well investigated. Fourier transform infrared spectra and X-ray diffraction spectra were also measured and discussed before and after adding waterborne polyurethane. Tentative mechanism of the interaction among the WPU, CA, and modified cotton fabrics is provided. The effect of cotton fabric pretreatment on fabric performance was also investigated. After the eco-process’s treatment, the fabric wrinkle resistant angle was upgraded to 271 ± 7°, tensile strength retention was maintained at 66.77% ± 3.50% and CIE whiteness was elevated to 52.13 ± 3.21, which are much better than the traditional CA anti-wrinkle finishing based on mercerized cotton fabrics. This study provides useful information for textile researchers and engineers.

本研究建立了一种棉织物的环保抗皱处理工艺。氢氧化钠-液氨预处理，然后添加6％（w / w）PU100柠檬酸垫固化干法涂饰。在此过程中，柠檬酸（CA）被用作精加工过程中的基本交联剂，因为它是一种非甲醛类，具有成本效益且抗皱性很好的试剂。环保型水性聚氨酯（WPU）被用作添加到CA整理液中的添加剂。系统地调查了六个商用WPU。织物特性如抗皱性，拉伸强度保持性，白度，耐久压性，柔软性和润湿性得到了很好的研究。在添加水性聚氨酯之前和之后，还对傅里叶变换红外光谱和X射线衍射光谱进行了测量和讨论。提供了WPU，CA和改性棉织物之间相互作用的初步机理。还研究了棉织物预处理对织物性能的影响。经过生态工艺处理后，织物的抗皱角提高到271±7°，拉伸强度保持率保持在66.77％±3.50％，CIE白度提高到52.13±3.21，远优于传统的CA抗-基于丝光棉织物的皱纹整理。这项研究为纺织研究人员和工程师提供了有用的信息。拉伸强度保持率保持在66.77％±3.50％，CIE白度提高到52.13±3.21，这比传统的基于丝光棉织物的CA抗皱整理要好得多。这项研究为纺织研究人员和工程师提供了有用的信息。拉伸强度保持率保持在66.77％±3.50％，CIE白度提高到52.13±3.21，这比传统的基于丝光棉织物的CA抗皱整理要好得多。这项研究为纺织研究人员和工程师提供了有用的信息。
