Silk vs Lyocell Compared: Cost, Benefits & Downsides

Key Takeaways

• Silk and lyocell both feel soft, but they differ sharply on sheen, thermoregulation, pilling, and price once the fabric is in use day to day.

• Choosing on price alone tends to backfire: lyocell wins on machine washability and cost, while silk wins on insulation, longevity, and that signature smooth-glide finish on hair and skin.

• For the silk side of the comparison, Mayfairsilk leads with 100% Grade 6A Mulberry silk in 22 momme sheets and 25 momme pillowcases, giving you the densest, smoothest weave on the market for bedding that actually performs.

• The price gap is meaningful but explainable: silk fabric in the UK runs roughly £10 to £150+ per metre against lyocell at £4 to £12, reflecting silk's labour-intensive reeling process and longer useful life with proper care.

• Mayfairsilk's 25 momme silk pillowcases and 22 momme sheets carry OEKO-TEX Standard 100 certification and a 30-night sleep trial, so the silk choice comes with a quality floor and a way to test the difference at home.

Silk vs Lyocell: How They Compare

Silk and lyocell both feel soft against the skin, but they part ways on the things that matter once the fabric is in daily use: sheen, thermoregulation, pilling resistance, and price. Silk is a natural protein fibre with rich sheen, gentle insulation, and exceptional longevity when cared for properly, while lyocell is a semi-synthetic fibre made from wood pulp through a closed-loop process that delivers breathable softness at roughly a third of the cost. Which one fits depends on whether you want a fabric that ages gracefully and regulates temperature on its own, or one that handles a hot wash and a busy week without complaint.

Bedding has become the deciding category for most shoppers weighing the two, because that is where the differences in feel, warmth, and wear show up first.

If you are choosing between silk and lyocell for sheets, pillowcases, or everyday garments, this guide walks through production, texture, durability, thermal regulation, pilling, sustainability, common uses, and price so the decision is clear.

What Are the Key Differences Between Silk and Lyocell?

Production

Silk is a natural fibre produced by silkworms. The production process involves raising silkworms that spin cocoons of fine silk filaments. The cocoons are carefully harvested, and the filaments are extracted through a process called reeling. Those fibres are then cleaned, spun, and woven into fabric. The method is labour-intensive and depends on skilled handling to keep the quality of the silk intact.

Lyocell is a semi-synthetic fibre made from wood pulp, usually sourced from trees like eucalyptus, beech, or spruce. The wood pulp is dissolved in a non-toxic solvent to create a viscous solution. This solution is then forced through spinnerets in a process called solvent spinning to regenerate cellulose fibres. These fibres are washed, dried, and spun into yarns to be woven or knitted into fabric. The lyocell production process involves a closed-loop system where most of the solvent and water are recovered and reused.

Texture & Feel

Silk feels smooth, glossy, and rich against the skin, with a natural shine that gives it that unmistakable luxurious vibe. It’s light, fluid, and instantly recognisable. 

Lyocell is gentle and breathable with a matte finish. It feels a bit like cotton blended with silk but doesn’t quite match silk’s signature glow.

Durability & Care

Silk is strong in fibre but delicate in fabric, prone to snags, and best kept away from harsh washing cycles. Most silk pieces require either handwashing or dry cleaning. 

Lyocell is more forgiving. It is tough, holds up well even when wet, and is usually machine washable on a gentle cycle, which makes it easier to live with day to day.

Lyocell’s tight weave and natural strength make it a low-maintenance fabric. It also holds up to regular washing without losing its softness.

Thermal Regulation

Silk shines in cooler conditions. It traps warmth effectively without bulk, thanks to its natural insulating qualities, making it perfect for layering or sleeping through chilly nights. 

Lyocell is breathable and cool to the touch, but it does not hold heat the same way. It suits warmer climates or anyone who runs hot at night, though it will not insulate like silk when the temperature drops.

Pilling Resistance

Fabric that stays smooth over time is a win, especially for pieces you wear or use often. Silk, especially high-grade mulberry silk, holds up well. Its long, smooth fibres naturally resist pilling, so it keeps that clean, polished look much longer. If you’re after fabric that still looks fresh after repeated use, silk is the one that tends to age more gracefully.

Lyocell is soft and durable, but depending on how it’s woven or what it’s blended with, it can start to pill in areas that see a lot of movement. 

Environmental Impact & Sustainability

Silk and lyocell are both impressive when it comes to eco-friendliness, but mulberry, especially the kind used by Mayfairsilk, raises the bar. 

It requires minimal land and water, avoids harsh chemicals, and thrives mostly on natural rainwater. Nothing goes to waste: silkworms become a food source, leftover leaves feed cattle, lower-grade silk is used in duvets, and sericin proteins are repurposed for cosmetics and pharmaceuticals. Even fabric scraps are turned into new products.

Lyocell is no slouch either, with its closed-loop production that recycles water and solvents to keep pollution low. Still, silk edges ahead with its ultra-efficient resource use, zero-waste approach, and ability to put every part of its production cycle to good use.

Price & Market Position

The current UK market price for 100% silk fabric ranges from roughly £10 to £150+ per metre, with most quality dressmaking silks falling within the £15 to £50 per metre range. Premium designer and specialty silks sit at the upper end of the spectrum, reflecting superior quality, exclusive designs, and often Italian or European manufacturing.

In contrast, lyocell fabric prices typically fall between £4 to £12 per meter, making it a more budget-friendly option.

Thus, silk remains a luxury textile with prices roughly 2 to 4 times higher than lyocell, reflecting its natural origin, labour-intensive production, and premium market positioning.

Best Uses for Each Fabric

Ideal Applications for Silk

Silk is perfect for pillowcases and sleepwear. Its smooth, gentle texture makes it ideal for skin and hair, bringing a little luxury to your nighttime routine.

Silk brings an unmistakable sense of elegance to anything it touches. Evening gowns, formal wear, and fine lingerie all benefit from its smooth texture and natural sheen. It glides comfortably against the skin, making it a go-to for sleepwear and pillowcases that help reduce friction on hair and skin during the night.

Applications for Lyocell 

Lyocell is great for everyday pieces that need to feel soft and stay fresh. Bedding made with lyocell stays breathable and cool, perfect for restful sleep. It also works well in activewear, travel outfits, and undergarments, offering lightweight comfort, moisture control, and lasting durability through regular wear and washing.

Silk vs Lyocell Comparison Table

How Should You Choose Between Silk and Lyocell?

Mayfairsilk makes sleep feel elevated with pure mulberry silk in every layer: pillowcases, sheets, and duvet covers. 

Silk and lyocell both deliver soft, breathable comfort, but the practical gaps in sheen, thermoregulation, pilling resistance, and price separate them clearly once the fabric is in use. The honest framing is that the two fabrics often serve different purposes rather than competing head to head, with silk earning its place in bedding and pieces that warrant premium care, and lyocell suiting daily-use items where convenience comes first.

For buyers leaning toward silk, the grade and momme weight do the heavy lifting. 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. That is the version of silk worth comparing lyocell against.

Why is silk considered a luxury fabric?

Silk’s natural sheen, softness, and insulating properties, combined with its labour-intensive harvesting process, contribute to its luxury status and higher price point.

How should I care for silk versus lyocell?

Silk requires delicate care, often hand washing or dry cleaning, while lyocell is more durable and usually machine washable on gentle cycles.
