Research overview:
Fine fiber cocoons are produced by using artificial forage added with a medical agent for animal inducing three times of sleeping. By giving this artificial forage to silkworms in a family making yellow cocoons, and by feeding mulberry leaves during the last week in the fourth age just before making a cocoon, glossy and soft silk is obtained. We have evaluated practical values of this silk when it is used as raw material of Nishijin fabrics for dyeing in advance. It is a feature of artificial silk that the ratio of refining reduction reaches 20% at most. However, refined conditions of the last stage mulberry silk were different from those of all ages artificial silk (ordinary forage, forage added with an agent inducing three times of sleeping), probably caused from difference in structure of the most external layer of sericin. Also, apparent Young's modulus became smaller. It is conjectured that difference in crystalline structure of silk thread influences on internal fibroin.
