Abstract:

Colloidal crystal (CC) fiber has unique light manipulation properties, fiber flexibility, and the potential to be used in the textile industry as an alternative to chemical dyes. Introducing polyamide 66 (PA66) into CC fiber can effectively improve the performance of fibers. In this study, polyamide 66 (PA66) CC fibers with various morphologies were fabricated by electrospinning using high-tensile PA66 and P(St-MMA-AA) latex particles as raw materials, such as closepacked, inlaid, noodle-like, spindle knots, bamboo-like, semi-enclosed, hat-like, etc. The formation mechanism of various fibers was analyzed based on the phase separation and assembly interaction. The prepared PA66 CC fiber film was reported to have unique structural color and enhanced mechanical properties, which can be used as a substrate for drawing various patterns. This work will provide a novel idea for the fabrication of functional CC fiber, which is helpful for the potential applications in the textile industry.
