What is silk fabric? Advantages, disadvantages, classifications, and applications

Silk fabric is one of the precious and luxurious materials in the textile industry, widely used in clothing design. While familiar to fashion enthusiasts, if you want to delve deeper into what silk fabric is, Ru9 will help you explore its origin, production process, as well as its advantages and disadvantages in the following article!

1. What is silk fabric?

What kind of fabric is silk? Silk fabric, also known as silk, is a high-grade material woven from silkworm threads. With its soft, smooth fibers and natural sheen, silkworm silk fabric not only brings sophisticated beauty but also exudes luxury.

These outstanding characteristics have made silk one of the most expensive fabrics in the world, favored in high-end fashion.

1.1. Origin of silk fabric

Silk fabric originated in ancient China, where the art of silkworm rearing and silk weaving was invented approximately 5000 years ago. For many millennia, the sophisticated technique of silk production was kept a national secret by the Chinese. It was only later, through adventurous journeys on transcontinental land routes, that this intricate technique gradually spread to the world.

Today, China remains a leading country in the production and export of silk fabric. This fabric's origin is closely linked to the silkworm's silk-making process. For many centuries, China held a monopoly on the production and trade of silkworm silk. It was not until ancient times that silk weaving techniques gradually spread to India, Southeast Asia, Central Asia, and Europe.

Currently, the research and production of silk fabric are no longer limited to China but have spread to many countries worldwide. However, Chinese silk is still highly valued by experts for its superior quality and special cultural significance.

1.2. What are the characteristics of silk fabric?

Silk fabric can be classified based on three main characteristics: mechanical, physical, and chemical.

Regarding mechanical properties, silk fabric has high durability, which increases its lifespan. However, silk's elasticity is quite low compared to many other fabrics, making it less resilient when under tension.

Regarding physical properties, silk fibers have a triangular structure, which allows the fabric surface to reflect light in multiple directions. Thanks to this, silk fabric always has a natural sheen and a characteristic sparkling appearance, creating a sophisticated and attractive look that few other fabrics can match.

Regarding chemical properties, silk fabric has good water absorption, effectively wicking away sweat in hot weather. At the same time, silk also retains heat well, providing a warm feeling on cold days. Thanks to these characteristics, silk fabric is not only beautiful but also provides maximum comfort to the wearer.

2. Silk fabric production process

Stage 1: Silkworm rearing

The ideal silkworm rearing time of the year is in spring and autumn, when the climate is cool, helping silkworms grow well. The process from hatching to spinning cocoons takes about 23 – 25 days, during which silkworms undergo 4 molts and are divided into 5 different age stages.

Silkworms primarily feed on mulberry leaves, and the mulberry must be grown in clean soil, free from pollution or alum effects. Silkworms eat day and night, and when they reach sufficient size after 3 molts, they will move to a suitable place to spin silk and create cocoons.

Stage 2: Spinning silk to create cocoons

Families that grow mulberries and raise silkworms often use a "né" (a device made from jute stalks), which is made of 5 layers with airy rectangular cells for silkworms to begin spinning cocoons. Initially, the silkworms spin silk to create an outer shell, keeping the cocoon fixed. Then, the silkworms will move in a figure-eight pattern about 3000 times, continuously spinning silk, forming a single thread nearly 1000 km long wrapped around the cocoon.

Stage 3: Silk reeling

After the silkworms spin their cocoons for 7 days, the reeling process begins. This stage happens quickly, within 5 days, to prevent the silkworms from hatching into moths and biting through the cocoons, which would break the silk and prevent it from being reeled into thread. To reel the silk, cocoons are soaked in boiling water, which helps dissolve the sericin in the silk, thereby identifying the silk filaments and beginning the reeling process.

This is the step to prepare raw silk threads for the next weaving stage. Depending on the desired purpose and type of product, the amount of silk thread needed will vary.

Stage 4: Silk weaving

Depending on the quality of the silk threads, the weaving method will be adjusted to control the thickness of the silk fabric. It is during the weaving process that the fabric's characteristics such as sheen, softness, and stiffness are determined, creating many different types of silk fabric.

Stage 5: Silk fabric dyeing

This is the final step in creating the aesthetic beauty of silk fabric. Initially, silk fabric has the natural ivory color of silk, so to achieve diverse and attractive colors, the fabric needs to go through a dyeing process. Before dyeing, the silk is soaked in hot water to remove excess gum on the fiber surface. Dyeing villages often use natural materials such as tree bark, leaves, and brown earth to color the fabric.

Depending on customer requirements and color coordination, silk fabric can be dyed into various patterns such as small floral silk, polka dot silk, plain silk, shiny silk, floral silk, or white silk, etc.

3. Popular types of silk fabric on the market

Silk comes in many different types, not only based on its origin as previously mentioned, but also categorized by the specific characteristics of each silk type.

3.1. Sand wash silk fabric

Sand wash silk fabric, or Silk Sand, is a soft, thin, and draping fabric often used for traditional Vietnamese dresses (áo dài). The special feature of sand wash silk fabric is its matte surface, which feels like touching sand grains moving on a desert. Thanks to this characteristic, sand wash silk fabric is very popular in Vietnam.

3.2. Silk satin fabric

Silk Satin, also known as Satanh, is a type of silk with a shiny, smooth surface, completely different from sand wash silk. The silk threads are woven using a twill weave technique, a method that tightly interlocks the fabric fibers. This technique not only creates a lustrous appearance but also makes the silk durable in use.

This technique may have appeared on television, where the weft thread passes under the warp thread and lies on top of the warp thread. Then, the weft thread shifts two warp threads to the right and continues to move up one warp thread, and this process repeats until completed.

3.3. Shiny silk fabric

Shiny silk, though seemingly different, is actually a thin, smooth, and less elastic fabric. Artisans craft Shiny Silk using a layered weaving technique, where the top surface of the fabric is woven with many parallel weft threads. Thanks to this technique, the fabric has a high sheen and reflects light better.

3.4. What is Kate silk fabric?

This fabric, also known as Kate Silk, is the most common and easily recognizable type. It is often used for everyday clothing, especially uniforms for students and employees in schools, companies, or businesses. The fabric is made from 100% PE, is less prone to wrinkling, and has high colorfastness over time, but its sweat absorption is quite poor.

3.5. Silk cotton fabric

Also known as blended fabric, this type of fabric is a combination of silk and cotton fibers, thereby offering many advantages of both materials. With a glossy surface, antistatic properties, and wrinkle resistance when washed, the fabric is widely used in everyday apparel.

3.6. Pure mulberry silk fabric

This is the highest-grade commercial silk, crafted entirely by hand through every stage. From the silk threads spun by silkworms, artisans meticulously reel and weave them into complete silk sheets, typically featuring a natural ivory color and no patterns.

Because silkworm threads are monochromatic, this type of silk fabric is not elaborate in patterns, but its value lies in its purity and superior quality. In ancient times, pure mulberry silk was even used as a unit of exchange in trade and commerce.

3.7. Brocade silk fabric

Brocade silk is a high-quality fabric created by combining silk and brocade, offering a perfect blend of silk's softness and brocade's thickness and luxury. The fabric often features intricate patterns, a smooth surface, and a sturdy texture. Brocade silk is primarily used for formal wear, evening gowns, or designs with a royal, aristocratic style.
