All About Mulberry Silk

Mulberry silk is considered the highest quality silk in the world due to its long, uniform filaments and refined, lustrous finish informs Dr N Gokarneshan  and Dr D Anita Rachel.

Mulberry silk is the highest quality, most durable, and softest natural fibre, produced by Bombyx mori silkworms fed exclusively on mulberry leaves. It is characterised by exceptional smoothness, hypoallergenic properties, and temperature regulation, making it ideal for luxury apparel, bedding, and skincare products due to its gentle, low-friction texture.

Key properties of mulberry silk

Mulberry silk has distinguished properties as follows;

Supreme softness and smoothness: Features a long, uniform fibre structure that is incredibly smooth, providing a luxurious, skin-friendly feel.

Hypoallergenic and natural: Contains sericin, a natural protein that repels allergens like dust mites and mold, making it ideal for sensitive skin.

Temperature regulation: Breathable and adaptable, keeping the user cool in summer and warm in winter.

Moisture-wicking: Effectively absorbs and evaporates moisture, ensuring comfort and hydration retention for skin and hair.

Strength and durability: Known for being strong and less prone to pilling or tearing compared to other fabrics, with a high tensile strength due to its fibroin protein.

Lustrous appearance: Naturally shiny and white, making it easy to dye and visually appealing.

Key applications of mulberry silk

This type of silk can be applied for various applications such as;

Luxury bedding and sleep accessories: Used for pillowcases (which reduce skin wrinkles and hair breakage), sheets, and duvets due to its smooth, friction-free surface.

High-end apparel: Used in delicate shawls, evening wear, blouses, ties, shirts, and lingerie.

Hair accessories: Used in silk scrunchies and ribbons to prevent hair frizz and split ends.

Biomedical and medical uses: Due to its biocompatibility, it is used in surgical sutures and tissue engineering, such as artificial blood vessel grafts.

Home furnishings: Utilised in luxurious curtains, draperies, and cushion covers.

Mulberry silk is favored for being 100 per cent natural, biodegradable, and sustainable, offering a combination of functional, health-conscious, and aesthetic benefits.

Mulberry silk is a 100 per cent natural protein fibre produced by the Bombyx mori silkworm, which feeds exclusively on mulberry leaves. It is widely considered the highest quality silk in the world due to its long, uniform filaments and refined, lustrous finish.

Key properties

Mulberry silk is distinguished from “wild” or other types of silk by several unique physical and chemical characteristics:

Texture and appearance: It is exceptionally soft, smooth, and has a natural pearly sheen. Unlike other silks that can be rough or uneven, mulberry silk consists of long, continuous fibres that result in a more consistent and refined fabric.

Strength and durability: It is one of the strongest natural fibres, featuring high tear resistance and longevity when properly maintained.

Temperature regulation: The fabric is highly breathable and naturally thermoregulating, helping to keep the body cool in summer and warm in winter.

Hypoallergenic and skin-friendly: It naturally repels dust mites, mold, and fungus. It contains the protein sericin, which reduces the likelihood of allergic reactions, making it ideal for sensitive skin.

Moisture management: It has excellent moisture-wicking properties, absorbing and releasing moisture easily without feeling wet to the touch.

Eco-friendly and biodegradable: As a natural fibre, it is fully biodegradable and has a lower environmental footprint compared to synthetic materials like polyester.

Common applications

Due to its luxurious feel and health benefits, mulberry silk is used across several industries:

Luxury bedding: It is the “gold standard” for high-end pillowcases, sheets, and duvets because it reduces friction on hair and skin, preventing bedhead and sleep wrinkles.

Fashion and apparel: It is a staple for sophisticated clothing, including evening gowns, bridal wear, blouses, and lingerie.

Accessories: Common items include silk scarves, neckties, sleep masks, and hair scrunchies.

Medical and biomedical: Its biocompatibility allows it to be used for surgical sutures. Modern research also explores its use in tissue engineering, specialised bandages for wound repair, and drug delivery systems.

Beauty and skincare: Silk-infused skincare products utilise its proteins to nourish and hydrate the skin.
