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.
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).
What Are the Pros and Cons of Silk Fabric?
Silk is known for its beautiful drape and absorbent nature, along with other positive factors, including:
Strength and durability. It is also one of the strongest natural fibers, though some of its strength diminishes upon getting wet. Silk is often blended with other fibers, such as cotton, for added sturdiness.Elasticity. The material’s flexibility makes it ideal for garments and upholstery.
Absorbency. Silk is one of the most absorbent fabrics, therefore it handles moisture well in clothing items. However, silk has some drawbacks as well, including:
Static cling. Since the material does not conduct electricity well, it can experience a lot of static.
Shrinkage. The fabric shrinks in the wash so a silk clothing item should always be dry-cleaned or the material should be washed before the clothing item is constructed.
8 Primary Uses for Silk Fabric
Silk is primarily used in garments and household items, but it is also employed in unexpected ways, such as in bicycle tires and in medicine.
