About silk and bourette

The silk was well known from the antiquity in China. According to a myth the legendary emperor Fuxi who as first found out an idea to use the silk worms of the moth, they feed on the leaves of mulberry tree, for the production of silk.

1. Collecting of the leaves of mulberry tree which are used as the forage for the silk worms

From the beginning the silk yarn was got so that it was unwound from cocoons into which the moth becomes a pupa during his conversion from the caterpillar to the butterfly. We can only reach for a quality yearns by the keeping of specific conditions of the silk culture, which were concealed for hundreds of years. This fact parted in a rise of mystery and many legends, which went with the silk.
   
For the silk culture was preferred the white mulberry tree (morus alba) for its fleshy and wide leaves by which the silk worms are fed. Above all the species Bmbyx mori was domesticated from many species of the spinner. It is the awkward butterfly that doesn’t fly and even look for any feed. He has only one role in his very short life – the reproduction.

3. Selection of cocoons which are suitable for the spinning of silk

Working steps of the production of silk and silk culture followed the plan, which was carefully worked up. Many literal works are about the production of silk with plinentiful of pictures. One of them is the book – Geng Zhi Tu. Different steps of the silk culture and cocoon processing is put down.
Parts of the filament, which are mechanically affected during the unwinding of cocoons, are processing by the spinning on the bourette yarns. The yarn has its typical character a little less homogeneous then the so-called pure silk. But all the qualities are identical. We use it for the 100% bourette fabrics or in combinations with the linen, wool, cotton or viscose.
