Most of the silk, which is used for weaving in textiles, comes from cocoons made by Bombyx mori larvae or silkworm, which is grown in captivity. This fabric has a brilliant appearance due to the prismatic structure of the fibers, which refracts incoming light at several angles. Silk fabric was first made in China since 3500 BC. Only kings could wear and give silk in ancient China, but the use of cloth was spread throughout Asia.
Around 1000 BC, silk trade extended to the Middle East, North Africa, India and Europe. It has now become an international trading position. Trade routes going from Europe to Asia, gathered collectively as the Silk Road. Although the Chinese emperors tried to preserve knowledge about the secret of silk, the technique nevertheless spread to Korea in 200 BC, and by 300 AD E. In India, silk was made.
Today, China is the largest producer of silk, and India is the second. Today, however, India is the largest user of silk. Brides traditionally wear silk sarees during wedding ceremonies in some parts of India, and silk is usually worn on holidays in India.
This comfortable and useful fabric was known throughout the Roman Empire. Although the emperor Tiberius passed laws prohibiting men from wearing silk clothes (because it was too luxurious and sophisticated), it did not help much to stop wearing silk.
Venice was the center of commerce, and because of this, many manufacturers settled in Italy. The 1200s Italian silk had a reputation for truly luxurious fabric. Silk made in the province of Como became the most valuable in the world, and by the end of the 19th century Italy had become the third largest producer in the world, best of all only by China and Japan.
Silk production arrived in America as early as the 1600s, when American colonists tried to start silk production, as did the shakers who live in what is now Kentucky and some New England residents. In the 19th century, European workers in Paterson, NJ, bought silk production there, which made Paterson the center of US silk production.
Silk is strong because of the amount of amino acid called glycine in it, which allows the fibers to pack tightly and tightly. Silk tensile strength is due to missing hydrogen bonds that resist even most acids. Sulfuric acid, however, will dissolve silk. Because of its remarkable properties, silk was used to make blankets, parachutes, and even bicycle tires.
Silk growing includes silk moths laying eggs on special paper. When the eggs hatch, the larvae are given mulberry leaves. After about five weeks, the larvae are ready to begin to rotate their koon, which they make on a straw frame placed above the tray where the larvae live. Silk is coated with a substance called seracine, and it hardens as soon as it comes into contact with air. A silkworm larva can scroll a mile of thread in two or three days. The cocoon completely covers the larva, and when the cocoon is complete, the larva dies in heated water and silk is collected.
This is a story about how beautiful silk appeared. Silk is one of the best fabrics you can buy. Silk bedding and pajamas are affordable luxury that will give you one of the little pleasures of life.
