Method for producing thread bundle derived from bagworm silk threads spun on the surface of a base material

Abstract

A bagworm silk thread spun on a base material was conventionally difficult to be collected, and thus, cannot be utilized. An object of the present invention is to develop and provide a method in which such a bagworm silk thread is peeled off from a base material with a weak force without being damaged and is collected as a thread bundle. Provided is a method for producing a thread bundle of a bagworm silk thread, including: applying, to a bagworm silk thread spun on the surface of a base material, a wetting liquid which presents a liquid form at least in the range of 20° C. or more and less than 30° C. and does not damage, denature, or dissolve the silk thread; and then separating the bagworm silk thread from the base material.
