The hollow-triangle PA6 composite shaped fiber produced by high-speed spinning with semi-dull polyamide 6 chips was designed and developed in our lab. Both the morphological structure and the rebound resilience of the fiber were observed and analyzed. Meanwhile, the weak acid, neutral and disperse dyes were applied to in the dyeing test. The results showed that the hollow-triangle fiber had a high degree of profile and good bulkiness. Furthermore, the immediate elastic recovery and total elastic recovery rate of the fiber were large. When stretched by 5%, the immediate elastic deformation of this fiber was 86.4% and its elastic recover rate was up to 100%, which is obviously better than that of the general PA6 fiber. Besides, the dyeing ability of the hollow-triangle PA6 fiber was nearly the same as that of the general one when it was dyed with different dyes under the normal technical conditions.
