热湿处理对山羊绒性能的影响

The effect of hot-wet treatment on cashmere fiber property

对分别经过高温蒸汽蒸纤和干热空气处理前后的山羊绒纤维进行强伸性能的测试,并通过目测方法评价了纤维的泛黄程度。结果显示,随着温度的升高和处理时间的延长,山羊绒纤维的强伸性能得到破坏。与干热空气相比,高温蒸汽加速了对纤维的破坏。此外,随着处理温度的升高,羊绒纤维开始泛黄。当温度达200℃时,纤维呈现出黄棕色。

In this study, the strength and elongation of the cashmere fiber before and after treated by high temperature steam and hign temperature air are tested with the yellowing degree also evaluated by visual assessmem. The result shows that the strength and elongation of the cashmere fiber are damaged with the increase in temperature and treatment duration. High temperature steam accelerates the damage of the cashmere fiber if compared to high temperature air. Besides, the cashmere fiber becomes yellow with the increase in temperature. When temperature reaches 200℃, the fiber became yellowish - brown.
