Title:
HIGHLY CONTRACTED SYNTHETIC FIBROIN TWISTED YARN AND PRODUCTION METHOD THEREFOR, AND SYNTHETIC FIBROIN TWISTED YARN AND METHOD FOR CONTRACTING SAME
Document Type and Number:
WIPO Patent Application WO/2019/194263
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a highly contracted synthetic fibroin twisted yarn having a sufficiently high contraction percentage, and a safe method for the production thereof. The highly contracted synthetic fibroin twisted yarn according to the present invention is a contracted synthetic fibroin twisted yarn containing a modified fibroin, and has a contraction percentage, defined by formula I, of at least 2%. contraction percentage (%) = {1 - (length of contracted synthetic fibroin twisted yarn/length of synthetic fibroin twisted yarn after twisting and before contaction with water)} × 100... (formula I)
