Table of Contents

Silk clothing is often synonymous with luxury, elegance, and timeless style, but there’s much more to this natural fabric than meets the eye. Silk has remained one of the most coveted fabrics worldwide. Yet, few people are aware of what goes into producing this luxurious material, the different types of silk available, or the environmental and ethical concerns surrounding its production. 

In this guide, we’ll dive deep into what makes silk so special, the various kinds of silk you might encounter, and practical tips for caring for your silk garments. Whether you’re a silk enthusiast or simply curious about this fascinating fabric, you’ll find everything you need to know to make informed choices about adding silk to your wardrobe.

What is Silk Made Of?

Silk stands as one of the most popular fabrics and is a natural fiber that is produced by silkworms. The silk production process begins with the cultivation of silkworms, where they craft protective cocoons. Harvesting these cocoons precedes the transformation of silkworms into moths, a step achieved through a boiling process that unfortunately results in killing the silkworms inside. Notably, it takes approximately 3,000 cocoons to produce just one yard of this fabric.

Where is Silk Produced?

China

China is the world’s top silk producer, with around 50,000 metric tons produced in 2023, accounting for approximately 70% of the global supply. They’re renowned for its production of luxurious Mulberry silk, which is highly prized for its smooth texture and lustrous quality.

India

India follows as the second-largest silk producer, with around 38,900 metric tons in 2023, contributing about 11% of global silk production. India’s silk industry is rich in history, known especially for unique varieties like Tasar and Muga silk.

Different Types of Silk

Mulberry Silk

Mulberry silk is one of the world’s most luxurious fabrics– and for good reason. What makes it stand out from other types of silk is its unique origin: the bombyx mori moth, which feeds exclusively on the leaves of the Mulberry tree (Morus Alba).  This diet results in silk fibers that are longer, stronger, and more uniform in size, producing a fabric that is stronger and more lustrous than other varieties. 

Tasar Silk

Tasar silk comes from the Antheraea Mylitta silkworm, which feeds on the leaves of the Asan and Arjun trees. Unlike the smooth, glossy finish of Mulberry silk, Tasar silk has a coarser texture and a more subtle sheen. Despite being less lustrous, it’s known for its durability and is also a more budget-friendly option. 

Muga Silk

Muga silk stands out for its natural golden hue, created by the Muga silkworm and produced exclusively in Assam, a state in northeastern India. Muga silk also has one of the highest tensile strengths among natural silks, making it as durable as it is beautiful.

Eri Silk (Ahimsa Silk)

Eri Silk is produced by the Samia Cynthia Ricini moth or Philosamia Ricini moth. These silkworms feed on the leaves of castor plants, which are notably drought-resistant and can thrive on less than 10 inches of rainfall a year- quite a contrast to Mulberry trees which require about 2 inches of rainfall every week.

What truly sets Eri silk apart is how it’s made. The silkworms spin irregular cocoons, making it impossible to produce  the traditional silk by boiling the cocoons before the moths hatch. Instead, the cocoons are boiled after the moths have emerged, earning Eri silk the name “Peace Silk”. This humane approach makes it particularly popular among Buddhist monks.

Advantages and Disadvantages of Silk

Benefits of Silk Clothing

Luxurious: Silk fabric is one of the most popular fabrics and gives off a beautiful, luxurious sheen that offers comfort and lightweight wear as a garment.

Durability: Silk clothing exhibit remarkable strength, allowing them to stretch without warping or sustaining damage. This makes them one of the best clothing fabrics and ensures that silk garments maintain their integrity and luxurious appeal over time.

Moisture-Wicking: Characterized by its hydrophobic nature, silk helps regulate body temperature in hot weather, providing a fresh and comfortable feel by wicking away moisture.

Wrinkle Resistance: Thanks to its inherent durability, silk resists wrinkling, making it an excellent option for those who prefer garments that stay smooth without frequent ironing.

Disadvantages of Silk Clothing

Cost Consideration: The luxurious quality of silk comes at a price, reflecting the intensive production process involved in creating this fabric.

Vulnerability to Elements: While silk is a strong fiber, it remains susceptible to water and sunlight. Even the slightest water droplet can leave an irremovable stain, and exposure to sunlight weakens the fiber, making it prone to rips and fading. Proper care is essential to maintain the longevity and pristine appearance of silk garments.

Remember, always check the care label on your silk clothing for specific instructions and consider individual garment characteristics when determining the best care practices.

How to Wash Silk in the Washing Machine

Silk’s delicate nature once made machine washing out of the question. But with a few simple steps, you can keep your silk clothes looking beautiful:

  1. Check the Care Label: Before anything else, read the fabric tag to ensure your silk items can be machine-washed. Some silk garments may be prone to damage or color loss in the wash.
  2. Sort and Protect: Wash silk items separately or with other lightweight fabrics. Avoid mixing with heavier items like denim. For extra protection, place your silk garments in a mesh laundry bag to prevent snags or abrasion.
  3. Choose the Right Detergent: Use a detergent made specifically for silk and delicate fabrics. Regular detergents can be too harsh and may strip the natural proteins from silk fibers.
  4. Select the Delicate Cycle: Always opt for the delicate or gentle cycle, and set the machine to the shortest possible cycle to reduce agitation.
  5. Set the Temperature: Follow the temperature instructions on the fabric care label, typically a cool or cold wash.
  6. Dry Gently: After washing, use a clean town to soak away excess moisture. Hang your silk garment or lay it flat to dry, but avoid direct sunlight, which can cause fading.

What’s the Best Detergent for Washing Silk?

Choose a detergent formulated for silk clothing, as these have a neutral pH level. Regular detergents have a higher pH level which can strip away silk’s natural proteins and weaken the fabric over time. A silk-specific detergent will help preserve the fabric’s integrity and keep your garments looking their best.

How Do You Iron Silk?

Ironing silk can be tricky due to its delicate nature, but with these simple steps, you can keep your garments smooth while maintaining their integrity:

  1. Start with Damp Fabric: Silk should be slightly damp while ironing to preserve its texture. Use a spray bottle or iron the garment right after washing.
  2. Turn it Inside Out: Always iron your silk clothes inside out to avoid damaging the fabric’s outer surface.
  3. Use the Lowest Heat Setting: Set your Iron to the lowest heat or silk setting, if available to avoid scorching the fabric.
  4. Protect with a Press Cloth: Lay your garment flat and cover it with a press cloth before ironing. A pillowcase or hand towel can work just as well to help shield the fabric.
  5. Press, Don’t Drag: Gently press the iron down on the wrinkled area for a few seconds, then lift it to let the fabric cool. Avoid dragging the iron across the surface, as this can stretch or burn the silk. Repeat on other sections as needed.
  6. Let it Cool Completely: Before removing the garment from the ironing board, ensure it’s completely cool and dry to maintain the shape.

Best Iron Silk Temperature

Always use the lowest heat setting to prevent damage. If your iron has a delicate silk setting, that’s even better for safe and effective ironing.

Silk Sustainability

Is silk production sustainable?

While silk is a luxurious and natural fiber, its production has a significant environmental footprint. The process requires large amounts of water and energy, making it one of the highest-impact fibers. Additionally, chemicals like insecticide methoprene are used to extend the cocoon-making period, increasing silk yields. Other treatments, including softening agents, bleaches, and dyes, are commonly applied to achieve the desired texture and color.

It’s also important to consider the environmental effects of cultivating the plants that feed the silkworms. Mulberry trees, for instance, require agrochemicals that can pose health risks to workers and contribute to pollution, affecting the surrounding environment and wildlife.

Is Silk Cruelty Free?

Regrettably, silk production is not considered sustainable, primarily because the conventional process involves the killing of silkworms during the cocoon harvesting phase. An estimated 1.2 trillion silkworms are boiled to death annually to sustain the silk industry. This aspect raises ethical concerns and underscores the need for alternative, more humane practices in the silk production industry.

Is Peace Silk Cruelty Free?

Peace Silk, also known as Ahimsa Silk, is not a straightforward, sustainable option. While it is considered a more ethical choice than conventional silk because it allows silkworms to mature and emerge from their cocoons without being boiled alive, there are ethical concerns in the breeding and care of the moths.

Frequently, moths are bred until their fertility decreases, after which they are left to die due to improper care, leading to a diminished quality of life. This brings to light the complexities and ethical considerations involved in the production of silk production.

Is silk biodegradable?

Despite the sustainability challenges in its production, silk is biodegradable. However, it’s important to note that pure silk, known for its incredible durability, may take about four years to decompose. This emphasizes the importance of responsible disposal practices to minimize the environmental impact of silk.
