Hilo de Silk

From cocoon filament to textile yarn

Silk production links the raising of silkworms with the preparation of their cocoons. In reeling, filaments from suitable cocoons are combined to form a continuous thread. Silk can also be spun from shorter material, including fibres recovered during processing and cocoons unsuitable for continuous reeling.

That distinction affects texture. Spun silk does not necessarily have the same smoothness or sheen as reeled silk, and shorter fibres can produce a more visible surface with wear. Both are silk. A yarn description that includes the production method gives you more information than a fibre percentage by itself.

The role of silk in a blend

Silk can contribute lustre and drape, while another fibre provides a different surface or balance of properties. In a brushed mohair-and-silk yarn, for example, the mohair halo and the underlying structure work together. Replacing it with a smooth silk yarn would change the fabric even if you could reach the same stitch count.

For substitution, identify what the silk is doing in the original yarn. Does the design depend on flowing drape, a glossy stitch surface or a fine strand supporting a halo? Compare construction and total length, and sample any strands held together as a combination. Wash the swatch using the label's method before checking dimensions. For garments with weight hanging from the shoulders, assess how the fabric moves and extends as well as how it looks laid flat.
