摘要：
An object of the present invention is to provide a high-shrinkage artificial fibroin twisted yarn having a sufficiently high shrinkage rate, and a safe method for producing the same. The high-shrinkage artificial fibroin twisted yarn according to the present invention is a shrunk artificial fibroin twisted yarn comprising a modified fibroin and having a shrinkage rate defined by the following Formula I of 2% or more: Shrinkage rate % = 1 − length of a shrunk artificial fibroin twisted yarn / length of the artificial fibroin twisted yarn after being twisted and before being brought into contact with water × 100
