- Silk. Silk is created by an insect called silk worm. Silk worm secrete a filament from their mouth by spinning itself into a cocoon. Silk worms are caterpillars.
- The first country to produce silk was China, then India, Italy, France, Asia and Japan started to produce silk.
- The life cycle of silk worm has four stages: The Egg, the silk worm, the pupa, and the moth.
- Silk worm like steady temperature. Silk worm like to be fed every 4 hours or 5 weeks before they get to be spin. Silk worms eat bushels of mulberry leaves per day.
- Silk producers in factories do the spinning process which means taking the threads from the cocoon after boiling the cocoon with the silk worm live inside the cocoon, and then spin the threads at 100 yards per minutes to makes a thread strong enough to weave. Unweaved silk looks like polyester bathing.
- The silk woms get killed during the process by being immerge in boiling water and cold immersion in order to take the threads off the cocoons. These silk caterpillars never get to turn into beautiful butterflies.
- Silk filament is held together by a gummy substance called sericin or silk gum. Then they are put through a series of hot and cold immersions.
- 3 to 10 strands of silk filaments are reeled at a time to produce the desired diameter of raw silk which is known as “reeled silk”.
- Silk is a natural fibers that is soft, lustrous and warm. Silk can be blended with other fibers. Silk is very easy to dye and print.
