Xuchang's leading enterprise Rebecca has developed high-performance hair fibers with a core-sheath structure, whose tensile strength and elongation are both close to those of human hair, breaking the foreign monopoly on high-end raw materials. Applied in high-end custom wigs priced at over 10,000 RMB, these fibers enable 360° free part styling. The gross profit margin of the enterprise's high-end products has risen to over 65%, marking its transformation from raw material processing to full independence and control across the entire industry chain.
