Abstract

Because of its antibacterial properties, wormwood can be used in the production of nanobiomaterials. In this paper, each stage of the production process of wormwood viscose fiber and flax fiber was determined. The carbon emission of each stage of the production process of 1 ton wormwood viscose fiber and flax fiber was analyzed by GaBi software, and the environmental impact of the production process was evaluated by using the CML2001 method provided by the software. The results showed that a total of 1690.04 kg of carbon dioxide was emitted in the production of 1 ton of wormwood viscose fiber, 60% in the preparation stage, 36.36% in the acid bath stage and 3.64% in the treatment stage. A total of 1541.41 kg of carbon dioxide was emitted in the production of 1 ton of flax fiber, with the pretreatment stage accounting for 39.95% of the total amount, the alkali cooking stage accounting for 50.06% of the total amount, and the pickling stage accounting for 9.99% of the total amount. The results can provide support for the production of antibacterial nanofibers.

基于GaBi软件生产抗菌纳米纤维的艾草粘胶纤维与亚麻纤维碳排放比较研究

由于其抗菌特性，艾草可用于生产纳米生物材料。本文对艾草粘胶纤维和亚麻纤维的生产工艺进行了测定。利用GaBi软件对1吨艾草粘胶纤维和亚麻纤维生产过程中各阶段的碳排放进行了分析，并利用该软件提供的CML2001方法对生产过程的环境影响进行了评价。结果表明，生产1吨艾草粘胶纤维的二氧化碳排放量为1690.04 kg，其中制备阶段的二氧化碳排放量占60%，酸浴阶段的二氧化碳排放量占36.36%，处理阶段的二氧化碳排放量占3.64%。生产1吨亚麻纤维共排放二氧化碳1541.41 kg，其中预处理阶段占总量的39.95%，碱蒸煮阶段占总量的50.06%，酸洗阶段占总量的9.99%。研究结果可为抗菌纳米纤维的生产提供支持。
