Method for producing long bagworm silk threads and production device therefor

Abstract

An object of the present invention is to develop a method of producing pure and long bagworm silk threads having no contaminants, such as pieces of leaves and twigs, and a device for implementing the production method. Provided is a method of producing a long bagworm silk thread, the method having a spinning process of making a bagworm having its nest hang its legs on a rail and continuously spin a silk thread along the rail, wherein the rail has a width smaller than the maximum width between the left and right legs when the bagworm used spreads out its legs and wherein the rail is such that the bagworm can hang its legs on the rail, and a collection process of collecting a long silk thread from the rail after the spinning process.

1 . A bagworm-derived silk thread having a continuous length of 1 meter or longer. 
     
     
         2 . A fabric comprising a silk thread according to  claim 1 .
