What is Silk, its Types & How is it Made?
Brief Information about Silk
Silk, the most luxurious fabric of all, is renowned for its sumptuous feel, soft nature, and shimmering appearance. From ancient China, where its production was a closely guarded secret, to modern-day fashion runways, silk continues to captivate with its enduring appeal.
In Indian society, silk was highly valued and regarded as a symbol of status, wealth, and luxury. Silk was commonly used by royalty, nobility, and elites to adorn themselves and display their prestige. The wearing of silk garments was often reserved for special occasions, ceremonies, and religious rituals.
Today, in this blog, we'll be unveiling everything about silk fabric, from what is silk? and how is silk made to properties and types of silk. This comprehensive blog about silk will throw light on the environmental impact and sustainability of traditional silk production and suggest some ethical and fashion choices like vegan silk. Let's unveil our curiosity.
History of Silk
The history of silk production can be traced back to ancient China, where legend attributes its discovery to Empress Leizu around 2700 BCE. The story goes that the 14-year-old Empress Leizu accidentally discovered silk threads while having a cup of tea in her garden when suddenly a cocoon fell into it. The empress noticed silkworms spinning cocoons and became curious. She then unravelled one of the cocoons and discovered the long, strong fibres within, which led to the development of silk production.
Initially, silk production was a closely guarded secret in China, with strict laws prohibiting the export of silkworm eggs and mulberry seeds. However, silk production eventually spread beyond China's borders through trade and diplomatic missions along the Silk Road. Thereafter, silk became highly sought after in regions such as India, Persia (modern-day Iran), Central Asia, and the Mediterranean.
What is Silk? & How Silk is Made from Silk Worms?
Silk, a natural fibre prized for its luxurious texture, shimmering appearance, and exceptional strength, originates from the cocoon of the silkworm, the larvae of the silk moth. Feeding primarily on mulberry leaves, the silkworm secretes a proteinaceous substance called fibroin, which solidifies upon exposure to air, forming a continuous filament. It then wraps this filament around itself in a figure-eight pattern to construct a protective cocoon.
Once the silkworm enters its pupa stage, it encases itself in several layers of silk, creating a dense, protective structure. Before reaching adulthood as a silk moth, the cocoons are carefully harvested and boiled to extract the silk fibres. These fine threads are then twisted together to produce silk yarn, which is used to weave silk fabric.

What is Silk Fabric?
Silk fabric, a hallmark of luxury, is crafted from the fine protein fibres spun by silkworms. Silk fabric is highly priced for its smooth texture, elegant drape, and versatility, making it a cherished choice across cultures and generations.
How is Silk Made? - Silk Production Process Steps
Silk is made through a process called sericulture, which involves raising silkworms, harvesting their cocoons, and extracting silk fibres. Let us take a detailed look at how silk is made by examining the steps involved in the silk production process below,
1. Mating of Silk Worms: Adult silk moths mate, leading to egg laying.
2. Silkworm Rearing: Silkworm larvae are nurtured on a diet of mulberry leaves.
3. Egg Hatching: Silkworm eggs hatch into tiny larvae, which are transferred to trays for feeding.
4. Larval Feeding: Larvae voraciously consume mulberry leaves, undergoing growth stages.
5. Cocoon Formation: Mature silkworms spin silk fibres into protective cocoons around themselves.
6. Harvesting the Cocoons: Cocoons are carefully harvested before pupae metamorphosis, typically through boiling or steaming.
7. Reeling: Softened cocoons undergo reeling to extract silk fibres.
8. Silk Yarn Production: Extracted fibres are spun into yarn.
9. Weaving: Silk yarn is woven into various fabric textures and finishes using traditional or modern techniques.

5. Hypoallergenic: Silk is hypoallergenic and gentle on the skin, making it an excellent choice for individuals with sensitive skin or allergies.
7. Moisture Absorption: Silk can absorb moisture up to 30% of its weight without feeling damp, helping to keep the wearer dry and comfortable.
8. Durability: Despite its delicate appearance, silk is surprisingly strong and durable, with fibres that resist stretching and breaking.
9. Versatility: Silk can be dyed in a wide range of colours and patterns, and it blends well with other fibres, allowing for endless creative possibilities in fashion and design.
The unique combination of softness, lustre, breathability, and durability makes silk fabric a highly-priced and sought-after.
Types of Silk
Silk comes in various types, each with its own unique characteristics and production methods. Some of the most common types of silk include:
Mulberry Silk
Mulberry silk is the most popular and widely produced type of silk in India. It is obtained from the cocoons of silkworms fed exclusively on mulberry leaves. Mulberry silk is known for its fine texture, smoothness, and lustrous appearance.
Tussah Silk
Also known as wild silk, Tussah silk is produced by silkworms that feed on a variety of plants, including oak and castor oil plants. Tussah silk has a coarser texture and a more matte appearance compared to mulberry silk. It often has natural variations in colour, ranging from creamy white to light tan or brown.
Ahimsa Silk / Peace Silk
Ahimsa silk, also known as peace silk or non-violent silk, is a type of silk that is produced in a cruelty-free manner. Ahimsa silk allows the silkworms to complete their life cycle and emerge as moths before the silk is harvested. This ethical approach ensures that no silkworms are harmed or killed during the process.
Eri Silk
Eri silk, peace silk or ahimsa silk, is produced by the Eri silkworm. Unlike other types of silk, Eri silk is obtained from the cocoons of the silkworm after the moth has emerged. Eri silk has a slightly nubby texture and is often used for upholstery, home furnishings, and handwoven textiles.
Muga Silk
Muga silk is a speciality silk produced exclusively in Assam, India. Derived from the cocoons of the Muga silkworm which feeds on the leaves of the Som and Soalu trees, Muga silk has a natural golden-yellow colour, durability, and lustrous sheen.
These are just a few examples of the many types of silk available. Each type of silk fabric has its unique qualities and alluring sheen.

Is Silk Sustainable and Environment-Friendly?
Silk production requires a significant amount of water for mulberry cultivation and silkworm rearing. The use of pesticides and chemical substances while harvesting silkworms and cocoon processing is not environmentally friendly.
Additionally, traditional silk production poses a serious threat to the lives of silkworms, as it involves boiling or steaming them alive along with the cocoons to extract the silk fibres. This results in the death of the silkworms, raising ethical concerns about animal welfare.
