Silk vs Bamboo Viscose: Differences, Prices, Pros & Cons

Key Takeaways

• Silk is a natural protein fibre spun by silkworms, while bamboo viscose is a semi-synthetic fabric made by chemically breaking bamboo pulp into cellulose threads.

• The two feel similar at first touch, but silk holds its sheen, structure, and biodegradability across years of use, where bamboo viscose softens faster and depends on a chemical-heavy production process.

• For buyers who want the genuine performance silk offers, Mayfairsilk's 25-momme Grade 6A Mulberry silk pillowcases and 22-momme sheets deliver natural sheen, thermoregulation, and durability that bamboo viscose cannot match at any price point.

• Silk typically costs two to five times more than bamboo viscose, with silk running £13.95 to £36.50 per metre versus £7.70 to £10.20 per metre for bamboo viscose in Western markets.

• Mayfairsilk's Grade 6A Mulberry silk pillowcases carry OEKO-TEX Standard 100 certification and a 30-night sleep guarantee, with every purchase planting a tree through Eden Reforestation Projects.

Silk vs Bamboo Viscose: How They Compare

Silk and bamboo viscose are the two fabrics most often compared for soft, breathable bedding and clothing, and they part ways on four things that matter once the fabric is in use: sheen, durability, environmental footprint, and price. Silk is a natural protein fibre with rich lustre, natural elasticity, and exceptional moisture management. Bamboo viscose is a semi-synthetic fabric made from chemically processed bamboo pulp, with soft feel and breathability at roughly a third of silk's price. Which one fits depends on how long you want the fabric to last and whether biodegradable end-of-life and natural sheen are part of the equation.

Both fabrics have grown sharply in popularity as buyers move away from polyester and synthetic blends, with silk holding its place at the luxury end of the market and bamboo viscose taking over the everyday softness category on a tighter budget.

If you're weighing the two for bedding, garments, or gifting, this guide breaks down production, properties, sustainability, durability, common uses, and price so you can decide which fabric belongs in your life.

What Are the Key Differences Between Silk and Bamboo Viscose?

Bamboo viscose looks and feels similar to silk, but it is more affordable and well suited to humid weather. 

Origins and Production

Silk: Silk has been prized for centuries, and production begins with the Bombyx mori silkworm. These silkworms spin cocoons packed with very fine threads. To make silk, the cocoons are carefully boiled and unwound into long, smooth fibres, then spun into thread. The process is time-consuming, but the result is the distinctive glossy fabric silk has been known for across generations.

Bamboo Viscose: Bamboo viscose follows a more modern production route. It begins with bamboo, a fast-growing plant, which is turned into pulp and treated with chemicals like caustic soda to extract its cellulose. That cellulose is transformed into soft, silky fibres through the viscose method. While bamboo as a crop is sustainable, the chemical process behind bamboo viscose creates environmental concerns.

Physical Properties

Silk is naturally soft and shiny, which produces its distinctive look and feel. It is stronger than its delicate appearance suggests, with the right amount of natural stretch for garments to flow and drape well. Silk keeps the wearer cool in heat and warm in cold conditions through its built-in thermoregulation. It breathes well, wicks moisture, and resists allergens, which suits sensitive skin. It also absorbs dye well, which produces vivid, lasting colours.

Bamboo viscose feels smooth and breathes well, which makes it suitable for hot, humid days. It adjusts to body temperature, naturally resists odours and bacteria, and is gentle on skin. While bamboo viscose is reasonably durable, it requires careful handling to avoid wrinkling or shrinking.

Comfort and Performance

Silk is the standard for fabric luxury, with soft, sleek, breathable performance. It adapts to body temperature and is gentle on sensitive skin, which makes silk both practical and elegant. Bamboo viscose feels smooth and effectively keeps the wearer cool, dry, and odour-free. It is comfortable year-round and naturally resists bacteria, which makes it suitable for everyday wear.

Sustainability and Environmental Impact

Silk, particularly the Mulberry silk used by Mayfairsilk, is among the most sustainable fabrics available when produced responsibly. The Mulberry trees that feed silkworms grow without pesticides or chemical fertilisers and rely mostly on rainwater. They also absorb carbon dioxide from the air. After spinning their silk cocoons, the silkworms themselves are used as delicacies in some cultures, leaving minimal waste.

Mayfairsilk's production process is designed with the planet in mind. Wastewater is treated responsibly, leftover Mulberry branches and leaves become natural fertiliser or animal feed, and every grade of silk is put to use. Lower-grade fibres become duvet fillings, and even the sericin protein extracted during processing is reused in cosmetics, food, and pharmaceutical products. This is part of Mayfairsilk's zero-waste approach.

Compared to bamboo, silk has a lighter environmental footprint. Silk requires less water, fewer chemicals, and significantly less energy to produce. Mayfairsilk's high-momme silk lasts for years, longer than most cotton or synthetic fabrics. At end of life, silk biodegrades naturally without shedding microplastics, which makes it gentle on the environment.

Bamboo as a crop is sustainable, fast-growing, low-maintenance, and pesticide-free. Converting bamboo into fabric is a different matter. The viscose process uses harsh chemicals that can harm the environment without proper containment. Some brands use closed-loop systems to recycle these chemicals, but this is not the industry standard. The process also requires significant energy, particularly when fossil fuels are the source.

Durability and Care

Silk is delicate and requires careful handling. Hand-washing or dry cleaning is best, and silk should be stored away from sunlight and moisture. With proper care, silk lasts for years.

Bamboo viscose is easier to handle. Wash gently and avoid heat to prevent shrinking or wrinkling. It does not need the level of care silk requires.

Common Uses

Silk brings elegance to garment design, appearing in gowns, lingerie, ties, scarves, and other luxury fashion staples. At home, silk appears in high-end bedding, pillowcases, and curtains. Silk is also used in medical sutures and dressings, where its strength and skin compatibility matter. In decor, silk adds richness to embroidery, artwork, and upscale interiors.

Bamboo viscose offers soft, breathable, comfortable performance across many product types. It appears in everyday outfits, baby clothes, underwear, loungewear, and activewear. It is also a favourite for sheets, duvet covers, towels, and bathrobes. Parents commonly choose bamboo viscose for baby blankets and sleepwear due to its gentle, skin-friendly nature.

Silk is a strong choice for premium bedding. It is soft, smooth, and elegant, adding both comfort and visual appeal. 

Price Comparison

Silk sits at the top of the price range, with costs usually between £13.95 and £36.50 per metre, depending on the type. Its luxurious quality is reflected in the price. Bamboo viscose is a much more affordable option, often priced between £7.70 and £10.20 per metre.

Note: The price ranges mentioned above are approximate and subject to change over time and across different locations. Costs may vary based on factors such as pricing policies, the provider's experience, and evolving market conditions.

How Should You Choose Between Silk and Bamboo Viscose?

Mayfairsilk turns everyday sleep into a luxury experience with rich, skin-loving silk that feels as good as it looks. It’s comfort, care, and elegance, all in one dreamy package.

Silk and bamboo viscose both deliver soft, breathable performance, but they part ways on sheen, longevity, and environmental footprint.

Silk is the better pick when you want the fabric to perform well, feel right, and last for years.

For buyers who have decided on silk, the grade and weight matter as much as the choice between silk and bamboo viscose itself. Mayfairsilk's 25-momme Grade 6A Mulberry silk pillowcases and 22-momme sheets sit at the top of the silk grading scale, with longer fibres, a denser weave, and a smoother surface than the 19-momme silk common at lower price points.

Frequently Asked Questions (FAQ)

Is bamboo viscose actually as soft as real silk?

Bamboo viscose is incredibly soft, just in a different way. While silk feels cool, smooth, and a bit slippery, bamboo viscose has a more cottony softness that many find cosier and less slick. In blind tests, people often can’t tell them apart, especially in bedding. So it’s not about one being softer, just a different kind of soft.

How long do silk and bamboo viscose products typically last?

Silk can last an incredibly long time with proper care, especially for items that aren’t washed often. But with frequent washing, it gradually breaks down. Bamboo viscose usually handles washing much better. 

Can people with allergies use both silk and bamboo viscose safely?

Yes, both are great for sensitive skin. Silk naturally resists dust mites, mold, and allergens, thanks to its tight weave and protein structure. Bamboo viscose is hypoallergenic too, with some built-in antimicrobial properties and no animal proteins, making it a safe option for anyone with silk sensitivities.

What's the difference between bamboo viscose and regular viscose?

It comes down to the source. Regular viscose is made using wood pulp, while bamboo viscose starts with bamboo. The process is mostly the same, but bamboo brings a few perks: better moisture control, a softer feel, and added odour resistance. That’s why bamboo viscose is becoming a favorite over standard rayon.
