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.

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.
