A novel method of drying dyed cashmere fiber by low temperature microwave was proposed and investigated in this paper, the effect of low temperature microwave drying on the properties of dyed cashmere fiber was characterized and discussed in details. The results showed that the mechanical properties of cashmere after vacuum microwave drying were improved, and the highest rise of elongation at break was more than 6 %. The directional friction effect was weakened, and the maximum DFE loss was more than 40 % compared with that of steam-dried cashmere. The scales were damaged, while molecular structure and chemical bonds of cashmere fibers have not changed. Vacuum and microwave combined drying method can dry dyed cashmere at low temperature quickly, which has considerable advantages compared with traditional drying, and shows great potential for eco-friendly production of cashmere.

提出并研究了一种新型的低温微波干燥羊绒纤维的方法，并对低温微波干燥对羊绒纤维染色性能的影响进行了表征和讨论。结果表明，真空微波干燥后羊绒的力学性能得到改善，断裂伸长率的最高上升幅度超过6％。与蒸汽干燥的羊绒相比，定向摩擦作用减弱，最大DFE损失超过40％。鳞片被破坏，而羊绒纤维的分子结构和化学键未改变。真空与微波结合的干燥方法可以在低温下快速干燥染色的羊绒，与传统干燥相比具有明显的优势，
