摘　　要：牦牛绒纤维皮质层细胞壁中分布大量黑色素,以颗粒形式存在,且稳定性高。本实验采用催化氧化法,通过一系列的实验,对氧化—还原脱色技术作了研究,通过改变脱色工艺中部分组分的用量、脱色温度和时间,并且随即测定牦牛绒的各种理化性能,如白度、碱溶解度、强力、断裂伸长率及其他的一些性能,使得脱色后的牦牛绒白度较高且牦牛绒纤维结构弹性、强力受损相对较低,从而得出了脱色的较优工艺处方和工艺条件。Massive melanin distributes in the cell wall of fibrous cortical layers of yak wool , which exists in particles and is stable .By adopting the method of catalyzed oxo-process and through a series of experi-ments , the decolorization technology of oxidization-deoxidization was studied .Through changing partial compo-nent amount used , decolorization temperature and time in the decolorization process and randomly checking the physical and chemical properties of yak wool such as the whiteness , the alkali solubility , the force, the break elongation ratio and other performance , the results showed that the decolorized yak wool had higher whiteness , and lower damnification of structure elasticity and force .Thus the optimized prescription and the conditions of decolorization could be concluded .
