【摘要】 针对羊毛服装产品全生命周期中的环境影响问题，运用生命周期评价方法，全面量化了1 kg羊毛服装产品的碳足迹，并对比分析了天然染料与合成染料在染色过程中的环境影响。结果显示，天然染料模型环境总影响为184.58 kg CO₂ eq,相较合成染料模型降低约4.48%,同时在多项环境绩效指标上表现更优。敏感性分析显示，染缸装载率为染色过程中的主要影响因素。高装载情境可大幅降低单位产品的碳排放和能耗，提升资源利用效率。当前模型未能充分考虑废水处理的影响，可能影响评估的准确性。更多还原

【Abstract】 In response to the environmental impacts associated with the entire life cycle of wool garments, the Life Cycle Assessment（LCA） methodology was employed in this study to comprehensively quantify the carbon footprint of 1 kg of wool garment. A comparative analysis was conducted on the environmental impacts of botanical dyes versus synthetic dyes during the dyeing process. The results indicate that the botanical dye model yields a total environmental impact of 184.58 kg CO₂ eq, representing a reduction of approximately 4.48% compared to the synthetic dye model. Additionally, the botanical dye model demonstrates superior performance across multiple environmental impact categories. Sensitivity analysis identified dye vat loading capacity as the primary influencing factor in the dyeing process. A high-loading scenario significantly reduces carbon emissions and energy consumption per unit of product while improving resource utilization efficiency. Furthermore, the study highlights that the current model does not adequately account for the impacts of wastewater treatment, which may affect the accuracy of the assessment.更多还原
