Bast flax fibers were treated, with or without ultrasound assistance, using a low melting mixture (LMM) composed of lactic acid, d-glucose and water. This LMM treatment affected both lignin and hemicelluloses contents and modified the fibers properties identified as crucial parameters in an industrial context, i.e. coloration, wettability, crystallinity, fibers diameter and chemical composition. Surface chemistry of the fibers were investigated through fluorescent tagged carbohydrates binding modules revealing macromolecular rearrangements responsible of both a fibers crystallinity enhancement and an unexpected hydrophobicity. It has been found that LMM treatments bleach fibers, which is considered a beneficial effect independent of the treatments.

低熔点混合物对木质纤维素亚麻韧皮纤维表面性能的影响。

使用由乳酸，d-葡萄糖和水组成的低熔点混合物（LMM）在有或没有超声辅助的情况下对韧皮亚麻纤维进行了处理。该LMM处理影响了木质素和半纤维素的含量，并改变了在工业环境中被认为是关键参数的纤维性质，即着色，润湿性，结晶度，纤维直径和化学组成。通过荧光标记的碳水化合物结合模块研究了纤维的表面化学，揭示了引起纤维结晶性增强和意外疏水性的大分子重排。已经发现LMM处理漂白纤维，这被认为是独立于处理的有益效果。
