摘要

本文的目的是通过生命周期评估,比较两种疏水性碳氟化合物处理方法对环境的影响和总成本:一种是新型等离子体表面改性技术,另一种是对织物进行传统的垫干固化处理。这两种技术被选为两种替代方法,轧干固化是一种传统的液基处理方法,而等离子体处理是一种新型的气基处理方法。这种比较是一种新的尝试,将为相关的工业利益方提供等离子处理技术与当前最先进技术相比的可持续性和经济可行性方面的信息。两种技术的生命周期清单都是根据技术纺织品研究中心使用实验室规模的设备进行的实验编制的。使用环境足迹 3.0 方法评估了对环境的影响,并用微生态点 (μPt)表示。研究结果表明,对于等离子处理(持续时间为 5 分钟,使用 13 立方厘米/分钟的 C2F6),其环境足迹比传统的垫干固化低 47%(每 10 克处理棉花的环境足迹为 8.95 μPt,而垫干固化为 18.9 μPt),总处理成本低 81%(每 10 克处理棉花的环境足迹为 1.03 英镑,而垫干固化为 5.47 英镑)。对等离子处理的环保性能影响最大的是耗电量,因此,在不损失工艺功能的前提下尽量缩短处理时间,并降低后续运营成本,将能获得最佳的等离子处理条件。

Environmental and economic impact assessment of hydrophobic treatment of cotton using low-pressure-low-temperature plasma
The purpose of this paper is to compare the environmental impact, using Life Cycle Assessment, and the total cost of two hydrophobic fluorocarbon treatment methods: a novel plasma surface modification technique and a traditional pad-dry-curing treatment of fabric. These two techniques have been chosen as two alternatives, with the pad-dry curing being a traditional liquid-based treatment and the plasma treatment a novel gas-based treatment. Such a comparison is a novel effort and will provide to the relevant industrial stakeholders an indication about the sustainability and the financial viability of the plasma treatment technique in comparison to the current state-of-the-art.
The Life Cycle Inventory for both techniques has been compiled based on experiments performed at the Technical Textiles Research Centre, using lab scale equipment. The environmental impact has been assessed using the Environmental Footprint 3.0 method and is expressed in micro ecopoints (μPt). The findings have revealed that for plasma treatment (duration of 5 min using 13 cm3/min of C2F6), the environmental footprint is 47% lower than the conventional pad-dry-curing (8.95 μPt per 10 g of treated cotton compared to 18.9 μPt) and the total treatment cost is 81% lower (£1.03 per 10 g of treated cotton compared to £5.47 using pad-dry-curing). The most significant contributor to the environmental performance of the plasma treatment is the electricity consumption, thus a minimization of the treatment time without losing the functionality of the process, and the subsequent operating expenses, will lead to the optimal plasma treatment conditions.
