HIGH-SHRINKAGE ARTIFICIAL FIBROIN SPUN YARN, METHOD FOR MANUFACTURING SAME, ARTIFICIAL FIBROIN SPUN YARN, AND METHOD FOR SHRINKING SAME

摘要

The present invention relates to a high-shrinkage artificial fibroin spun yarn which is a shrunk artificial fibroin spun yarn including a modified fibroin and having a shrinkage rate of greater than 1% defined by the following Formula I: $\mathrm{Shrinkage}\mathrm{rate}=\left\{1-\left(\mathrm{length}\mathrm{of}\mathrm{shrunk}\mathrm{artificial}\mathrm{fibroin}\mathrm{spun}\mathrm{yarn}/\mathrm{length}\mathrm{of}\mathrm{artificial}\mathrm{fibroin}\mathrm{spun}\mathrm{yarn}\mathrm{after}\mathrm{spinning}\mathrm{and}\mathrm{before}\mathrm{contact}\mathrm{with}\mathrm{water}\right)\right\}\times 100\left(\%\right)\mathop{\mathrm{image}}$
