Research on mechanical properties of different fineness superfine wool fiber

According to the properties of tensile and friction of 9 different fineness superfine wool fiber from 11.4~20.5 μm by tests,the paper studied the influence of the fineness of superfine wool fiber on the mechanical properties,and showed the general law of the influence between the fineness and the properties of tensile and friction.The experimental results showed that: in a certain degree of fineness range,With the increase of fineness,the tensile strength of superfine wool fiber first decline then increase gradually,and the relationship between the degree of fineness and friction was relatively complex,reflected in two aspects by friction factor and friction effect,the overall trend was quite stabilized and fluctuated within a certain range.
