Silk is a natural fiber known for its luster, shine, strength, and durability, and it has a long trading history across the world. Silk is the epitome of luxury due to its high cost to produce, soft feel, and elegant appearance, and it is thus a popular textile in high-end and couture fashion design.
What Is Silk?
Silk Yarns are natural fibers produced by insects as a material for their nests and cocoons. There are several types of insects that produce silk, including silkworms (the most common type of silk), beetles, honey bees, bumble bees, hornets, weaver ants, and many more. Made primarily of a protein called fibroin, silk is known for its shine and softness as a material.
What Is the History of Silk Production?
The earliest example of Silk Fabrics comes from China when it was used in a child’s tomb to wrap the body. China dominated the silk industry for many years, and initially the material was reserved for the Emperor. The Chinese used silk as a form of currency, and cost was measured in lengths of silk. The Silk Road, which connected industries from the East to the West, was a popular trading route named for the material, and that region of the world, still maintains the name today.
Eventually, silk production moved to Korea, Thailand, India, and Europe. The material finally made its way to the U.S. in the seventeenth century. King James, I introduced silk to the colonies, but many of the country’s early settlers couldn’t afford the material. Patterson, New Jersey and Manchester, Connecticut both became centers of silk production in the United States, until the trade and production was disrupted by World War II, leading to the creation of synthetic fabrics like nylon.
How Is Silk Made?
The process of making Silk Crepe Satin Fabric is called sericulture, and it involves harvesting silkworms for the material.
Larvae are fed mulberry leaves.
After they have moulted several times, they spin a cocoon. The silk solidifies upon contact with air. This process takes about 2 to3 days.
Once the cocoon is formed, it is dropped into a pot of boiling water effectively killing the pupae.
The silk filament is extracted by brushing the cocoon.
The raw silk is woven or knit into a fabric or spun into a yarn.
Note that it takes about 2500 silkworms to spin a pound of raw silk. Each cocoon contains about a mile of silk filament, and one thread of silk is made of 48 silk filaments. Different weaving processes result in different types of fabric, including crepe (a rough crinkled texture), organza (a thin, sheer fabric), and chiffon (a lightweight, plain-weave fabric with a slight stretch).
