Research on the structure and performance of new-type improved rabbit hairs
In order to improve the spinnability of rabbit hair fiber and expand the application of rabbit hair in different fields,a new-type improved rabbit hair in Mengyin County was analyzed by morphology features,and its mechanical properties,friction properties and curling properties were tested.The results show that the scale layer of the improved rabbit hair became thinner,the degree of scale outward projection decreased,the scales had no obvious overlap and the fiber got smoother;the length of the improved rabbit hair was 93.00 mm increased by 43.32%compared with the length of ordinary rabbit hair of 64.89 mm;the average strength reached 16.11 cN/tex which was somewhat improved compared with 14.97 cN/tex of the ordinary rabbit hair.Compared with the ordinary rabbit hair with 8.1 curls/(25 mm),the improved rabbit hair had 11.3 curls/(25 mm),which was 39.5%higher.The friction factors of the fibers in the downward and backward scale directions were decreased,and the effect of directional friction was weakened,so that the antifelting and shrinkage properties of rabbit hair fibers were improved.
