Bringing back farms Switzerland produces its own silk

For the first time in 100 years, silk is being produced in Switzerland. (SRF/ 

There are records of silk being made in Zurich as far back as the Middle Ages, and a number of workshops sprang up all around the country, but in 1914 the last silk factory was closed in Ticino. 

In 2009 a group of innovative farmers got together with the aim of promoting the breeding of silkworms and reintroducing the manufacture of silk products. 

Led by Ueli Ramseier, a farmer and textile engineer from canton Bern, they set up the Swiss Silk Association.

So far the association has produced 20 kilograms – enough to make 150 ties and 30 scarves, which are being sold under the label `Weisbrod’.

Breeding silkworms is quite challenging. The insects only thrive in the right climate. 

The creatures mate quickly after emerging from their chrysalis, and die a day or so after laying their eggs. There are 12 silkworm breeders in Switzerland.
