today’s fashionabulary focuses on that spectacular fabric called Silk.
Silk is a natural protein fibre, composed 80% of fibroin and 20% of sericin (gum), produced by certain insect larvae (the most renowned being mulberry silkworm Bombyx mori reared in captivity) to form cocoons.
Raw silk (“seta cruda” in Italian) is any silk thread from which the external gum has not yet been removed.
In fact, in order to improve silk sheen and elasticity, gum is removed by treating raw silk with hot water, thus obtaining either souplè silk, when only part of the gum is removed, or degummed silk (in Italian “seta cotta”), when all the gum is removed. Degummed silk can then be treated with a process called “weighting” in order to improve its resistance.
Silk that has been processed can be woven or knit into a variety of fabrics.
