A comparative analysis was conducted on the effects of Basolan treatment on the morphological structure and mechanical properties of yak cashmere,using yak cashmere and Basolan yak cashmere as research objects.The fiber fineness,surface morphology,friction properties,tensile properties and bending properties were tested.The results showed that the surface scales of Basolan yak cashmere were removed,and the average diameter of yak cashmere was 18.71 μm.The average diameter of Basolan yak cashmere was 17.42 μm.Therefore,the fineness of yak cashmere decreased significantly after Basolan treatment.After Basolan treatment,the average curl number of yak cashmere increased and the average curl rate decreased,influencing fiber elongation significantly.The average breaking strength of yak cashmere was 10.53 cN,and the average breaking strength of Basolan yak cashmere was 11.10 cN,but the difference in breaking strength between the two fibers was not significant.The static directional friction effect of Basolan yak cashmere was 7.62%lower than that of yak cashmere,and the dynamic directional friction effect was 6.88%lower,the anti-felting performance was better.The bending rigidity was 0.160 6 gf·cm2/cm compared with that of yak cashmere to 0.139 2 gf·cm2/cm,so the softness was also better.
