Thousands of years ago the Chinese had mastered the secret of using silk to weave cloth. This secret was kept so secret that anyone who brought silkworms or silkworm eggs out of China was beheaded. Today silkworms are raised not only in China but also in Japan, India, France, Spain and Italy. The most beautiful silk has been woven with the silk of silkworms – a worm – that feed on mulberry leaves.
In early summer, each moth lays about 500 eggs or more, these eggs are kept in paper or cloth bags until the following spring, when the mulberry tree leaves (perhaps the author describes how to raise silkworms). of Europe and America – ND). The eggs are then placed in the incubator. Here, the eggs hatch into tiny black worms. Worms were put into trays (nia) filled with chopped mulberry leaves. Here silkworms only have to eat around the clock for about six weeks. When the caterpillars can slowly twist their heads, that’s when they are about to pull the cocoon.

Here silkworms only have to eat around the clock for about six weeks. When the caterpillars can slowly twist their heads, that’s when they are about to pull the cocoon.

People put silkworms in “sticks” to make it easier to pull the cocoons. The silkworm wraps itself around with tiny barely visible threads that it releases from its belly through tiny holes in its jaws. A silkworm can release a silk thread about 500m to 1,000m long. The spinning process takes about 72 hours. After releasing the silk, inside the cocoon is only a pupa. This pupa can turn into a moth about 12 days later.
The whole cocoon is put in hot water for the pupae to die and at the same time for the soft and clean silk fibers to cling to the silk, making the silk tangled. Many silk threads are spun into a thread and rolled into a core. It takes 10 to 12 such threads to become a usable thread. Too little, the silk thread is easily broken. Too many yarns, the yarn is big, the silk weave looks rough. On the silk side, there are double and triple yarns, which means that the silk has been woven with double and triple yarns. Today’s very popular, very cheap nylon yarn has replaced silk. But nylon silk cannot have features such as soft, cool, light… like silk, so silk is still preferred.

The silkworm life cycle begins when a female silkworm lays eggs. Caterpillars or larvae are hatched from eggs of silkworms. Silkworms eat mulberry leaves and give birth to pupae. During the pupal stage, silkworms are woven around the net to hold the body. It then rotates its head, spinning a yarn made of protein and becoming a silk thread. Some caterpillars form a protective layer around the pupae, and this covering is called a cocoon
