Manufacturing of Amber Particles Suitable for Composite Fiber Melt Spinning
TLDR Researchers created small amber particles for use in bioactive and biocompatible fibers that could help with skin and hair restoration and are safe for infant clothing.
In 2016, researchers successfully developed a method to produce amber particles of up to 3 µm in size for incorporation into polyamide 6 fibers through melt extrusion and spin drawing. These particles retained their chemical composition post-grinding, as confirmed by various characterization techniques. The resulting amber-infused fibers were found to be bioactive and biocompatible, with potential benefits for skin and hair restoration, and met the human-ecological standards for infant fabrics. The study established an optimal grinding time of 30 minutes for the amber particles and utilized a two-stage extrusion process for better particle dispersion within the polymer matrix. The spinning process involved controlling pressure and throughput, with modifications in the winding process to reduce relaxation in the yarns. This technology paves the way for the production of amber composite fibers with medical and textile applications.
