Silk is a natural fiber, and the process of collecting and preparing raw silk has remained largely unchanged over the past 4,000 years. Silk is harvested from the cocoons of the larvae of the silkmoth, bombyx mori. After harvesting, the silk is processed, woven and dyed.
Several creatures secrete a form of silk, but their secretions are far inferior to those of the silkworm, which is the larval stage of the silkmoth. Many attempts have been made to produce a synthetic silk alternative, but the results have been poor and the quality much inferior to natural silk. The silkmoth is native to China, and it was the Chinese, more than 4,000 years ago, who discovered the silk-making process.
Chinese silk producers kept the origins of this extremely valuable and sought-after material an absolute secret. At one point, revealing any part of the silk-making process was an offense punishable by death. There are no longer any wild silkmoths; they survive solely in captivity, mainly on silk farms.
Intensive cultivation and domestication over the course of more than 4,000 years have resulted in the adult silkmoth evolving into a flightless creature with a fat body and tiny wings that are unable to lift the moth's weight. Instead, the adult moth crawls on legs that struggle to support its weight. The adult moth lives for up to one week, neither eating nor drinking, its sole purpose being to breed.
Female silkmoths lay up to 500 eggs, which take around two weeks to hatch into tiny caterpillars referred to as silkworms. The larvae only eat mulberry leaves that are chopped into small pieces and given every few hours. The silkworm grows rapidly, repeatedly shedding its skin until it reaches 3 inches (7.5 cm). The caterpillar then pupates and begins to secrete a liquid from two glands on the head; the liquid hardens as it reacts with the air.
This process is designed to protect the pupa and can take as long as three days. The secretion is a single, continuous thread and is raw silk. Once complete, the cocoon is placed into boiling water to kill the developing moth before it can emerge and destroy the silk. The cocoon is then carefully unraveled and placed on a large reel. From each cocoon, the strand of silk measures up to 2,953 feet (900 m).
The fine silk strands are wound together to produce yarn that can then be woven and dyed. Waste silk, such as flawed or short strands, is also processed. It is used to make short furnishings or clothing and items of inferior quality, which is reflected in the cost of the finished items. Reeled silk is the term given to the material of highest quality, and it is the most highly prized

How is Silk Made?
Some Tips to care your favor Nike Shoes
• Protection
Apply a protective product to the shoes before you ever step outside your house. Protective products can be in the form of oil, wax, and silicone spray available at most shoe stores. Each type of material (leather, suede, nylon etc) requires a special type of protective product. Do your research and choose which one is best for your shoes.
• Exterior Maintenance
If you can avoid it, don't wear the same shoes every day. Not only does this keep them from wearing out, but it's also good for your body. Allow the shoes a day or two to rest and dry before wearing again.
For regular sneakers made of canvas like Nike SB Blazer Low and high, hand wash with a mild detergent and cold water. Allow them to air dry after washing and do not throw them in the dryer unless you want them to lose their shape and/or melt. Smooth leather shoes, like some Nike Air Max Mens Running Shoe and Nike Air Shox NZ 2.0, we recommend special shoe cream or polish.
• Replacement
Shoes are subject to wear and tear. Most experts say that you should replace heavily used athletic shoes every three to four months. Replace less regularly worn shoes every six months to a year. So when the end has come, your shoes have reached their golden years, and you're ready to retire them to the collection or consign them to the trash, come back to Nikeshoes-buy for a replacement of your Nikes shoes.
