  • 可持续的化学

背景情况:

  • 基于纤维素的织品被广泛使用,但往往缺乏固有的疏水性质.
  • 迷香是提取精油的副产品,
  • 增值副产品符合循环经济原则和可持续的工业实践.

研究的目的:

  • 使用迷香的残留物使纤维素织品具有功能.
  • 描述迷香的成分,并优化其在织物上的应用.
  • 评估经过处理的织品的物理,化学和性能特性.

主要方法:

  • 福里埃变换红外光谱 (FTIR),气体染色学质谱 (GC-MS) 和高性能液体染色学 (HPLC) 用于特性.
  • 接触角度测量,水/空气透性,透气性,拉伸性和颜色测试用于织物评估.
  • 密度功能理论 (DFT) 模拟和键临界点 (BCP) 分析以研究分子相互作用.

主要成果:

  • 经过处理的织物获得了显著的疏水性 (接触角度> 120°) 和出色的色彩性能 (K/S = 12).
  • 观察到具有良好的洗和防腐性,极好的防光性和持久的疏水性 (98%).
  • DFT模拟显示,迷香成分 (肉酸,阿皮根因) 和纤维素之间存在强烈的结合相互作用.

结论:

  • 用迷香使纤维素织品功能化是一种可行的可持续策略.
  • 这种方法提高了织品的性能,同时促进了废物利用和循环经济实践.
  • 这项研究证明了织行业的智能,成功和环保方法.
