Cashmere vs Silk – The Ultimate Comparison

Think of the softness of a cashmere blanket or the elegance of a silk dress. These fabrics have long been cherished for their luxurious feel and timeless appeal. But what are the key differences between cashmere and silk?

In this ultimate comparison, we will explore every aspect of these exquisite materials, from their origins and production methods to their practical applications and maintenance. 

Raw Material and Production Process: How Cashmere and Silk Are Made

Cashmere Silk
Raw Material Derived from the undercoat of cashmere goats. Produced from the cocoons of silkworms.
Collection/Harvesting  Requires combing or shearing of goats during molting. Cocoons are carefully harvested from silkworms.

Processing

1. Sorting and cleaning to remove coarse hairs and debris. 

2. Spinning into yarn.  

3. Weaving/knitting into the fabric. 

4. Finishing (dyeing, washing, softening).

1. Degumming (boiling or steaming).

2. Reeling the softened cocoons to form threads. 

3. Spinning the threads into yarn.

4. Weaving/knitting into fabric. 

5. Dyeing and finishing.

Characteristics of Cashmere and Silk

  • Appearance and Texture: Comparing Cashmere’s Plushness to Silk’s Smoothness

Cashmere, derived from the fine undercoat of goats, offers exceptional softness and warmth. Its rich texture evokes a cozy sensation, making it a favored choice for comfort and warmth.

Silk fibers possess remarkable qualities – they are elastic, thin, and long. When woven into silk fabric, they create a tight, smooth structure with a delicate touch and vibrant colors, boasting a luxurious luster. Silk garments drape beautifully, emanating elegance.

  • Warmth: Is Cashmere/Silk Warm?

Cashmere provides more warmth than silk. It stands out for its warmth and lightweight among all winter fabrics. It is even warmer than wool. Why is cashmere so warm? Cashmere’s unique structure, with its irregular curls, creates gaps between fibers that trap heat, providing superior insulation against the cold. 

While silk may not provide the same level of warmth as cashmere during winter, it stands out as an excellent choice for year-round wear. Thanks to its special fiber structure, silk possesses natural thermoregulatory properties, making it suitable for both cold and warm seasons. 

  • Comfort: Which Fabric Feels Better, Cashmere or Silk?

Both cashmere and silk offer distinct yet comfortable wearing experiences. Silk’s smooth and cool touch provides a luxurious feel, while cashmere’s soft and warm texture creates a cozy sensation.

When it comes to cashmere, you may wonder: Is cashmere itchy? Don’t worry. Its softness and smooth surface ensure comfort without any itchiness. For those with sensitive skin, semi-worsted or worsted cashmere often provides a more comfortable option. However, cashmere can sometimes generate static electricity, which might make it less comfortable than silk. 

Silk, being lightweight and breathable, is often considered a comfortable choice for year-round wear. Its breathable nature ensures a cool and dry wearing experience during hot weather, while its lightweight nature makes it ideal for delicate accessories like eye masks and twillies without feeling bulky.

  • Moisture Absorption: Comparing Cashmere and Silk’s Moisture-Wicking Properties

Cashmere boasts the highest moisture absorption capacity among all fibers, with a moisture regain rate of approximately 17%. Cashmere fabrics can absorb moisture equivalent to 35% of their own weight, showcasing excellent moisture-wicking abilities. Similar to silk, cashmere possesses the ability to regulate skin temperature.

One of the characteristics of silk is its great moisture absorption ability. Though not as good as cashmere, silk still can absorb up to 30% of its weight in moisture. This ensures rapid sweat absorption, contributing to dry and comfortable skin.

  • Durability and Longevity: Comparing the Lifespan of Cashmere and Silk

Cashmere fabrics are prized for their durability, often lasting between 3 to 5 years and sometimes even longer. Despite the delicate feel of cashmere fibers, their curliness results in tightly woven fabric structures that resist pilling and shedding to a certain extent. Moreover, the elasticity of cashmere fibers ensures garments maintain their shape and resist stretching and deformations.

Meanwhile, silk is one of the strongest natural protein fibers available. Its thin, long, and elastic fibers contribute to relatively durable fabrics with a surprisingly long lifespan, provided they are worn and cared for properly.

Environmental Impact

  • Sustainability: Is Cashmere/Silk Sustainable?

The production process of cashmere raises concerns about its sustainability, while it is biodegradable and recyclable. Many cashmere pastures prioritize economic gains over environmental conservation, leading to overgrazing and the depletion of pasture resources. This unbalanced approach disrupts grassland ecosystems and exacerbates carbon dioxide emissions, contributing to the greenhouse effect. 

In contrast, silk emerges as a more sustainable option. Biodegradable and renewable, silk production involves domesticating silkworms in controlled areas, minimizing environmental impact. Silkworm domestication requires less land and water compared to cashmere production, making it a more eco-friendly choice.

  • Ethical Considerations: Production Practices and Animal Welfare

In the rearing stage, many ranches prioritize economic efficiency over goat welfare. Trimming goats’ cashmere, far from being a gentle process, often involves harsh handling with sharp metal combs, causing distress and potential skin damage. Shockingly, many goats with average-quality hair are euthanized as a result. 

Similarly, silk production involves the killing of silkworms, raising ethical concerns. However, there are alternatives such as peace silk, which prioritizes the protection of silkworms. The good news is that more and more brands are focusing on sustainability. As consumers, you can support these brands and contribute to sustainability by recycling your cashmere or silk products.

Versatile Applications of Cashmere and Silk

Cashmere is a sought-after choice for home and fashion applications. Comforters and carpets made of cashmere can be remarkably warm and cozy. Cashmere also finds versatile applications in the fashion industry. Cashmere effortlessly elevates your style, whether it’s a casual sweater for a leisurely autumn outing or an exquisite shawl for a banquet.

Silk, favored by luxury brands for its lustrous sheen and graceful drape, is a popular choice in fine clothing. Beyond its role in fashion, silk is also prized for its strength, making it ideal for durable home furnishings. Moreover, silk’s lightweight, breathable, and skin-friendly properties make it a popular choice for underwear and bedding.

Maintenance and Care: How to Maintain the Quality of Cashmere and Silk?

Proper care is essential for maintaining the beauty and longevity of both cashmere and silk garments. While their care routines are similar, one key difference is that cashmere requires less frequent washing and needs a cashmere shaver to remove lint.

  • How to Wash Cashmere and Silk?

Dry cleaning is recommended for both fabrics. However, if machine or hand washing is preferred, it’s important to use the delicate cycle, along with a mild neutral detergent, in cold or lukewarm water. After washing, avoid wringing cashmere or silk. 

  • How to Dry Cashmere and Silk?

Avoid using tumble dry. Both fabrics should be kept away from direct sunlight when drying. Cashmere garments should be laid flat to prevent stretching and deformation, while silk garments can be hung to dry. 

Price and Affordability: What is More Expensive, Cashmere or Silk?

Generally, high-quality cashmere is more expensive than silk. Cashmere is often associated with luxury, referred to as “soft gold”. Why is cashmere so expensive? It comes down to two main factors: scarcity and a complex production process.

Cashmere is derived from the fine undercoat of winter goats, and it’s only harvested once a year. Globally, we produce a mere 20,000 tons of raw cashmere annually, compared to over 80,000 tons of silk. Furthermore, making a high-quality cashmere sweater requires at least 16 distinct steps.

Silk is also an expensive fabric, though its price is not as high as cashmere. Like cashmere, silk production is labor-intensive, requiring significant human effort. Furthermore, the annual silk production has been impacted by climate change and environmental pollution, leading to instability in the supply.

However,  price isn’t just about the fabric itself. The quality of the product, the production methods used, and the brand’s reputation all influence the final cost.  Sometimes, silk products with exceptional materials or unique production techniques can be more expensive than standard cashmere products.

FAQs
