Raw Silk Yarn: 20/22D, Dupion, Luxury & Organic Silk
Core supply
We supply four varieties of raw silk yarn — 20/22 denier white raw silk, natural dupion silk yarn, luxury silk yarn and GOTS-certified organic silk — sourced from Yizhou, China, the world's largest raw silk region.
As a Yizhou raw silk supplier, we ship mulberry raw silk yarn — also called filature silk or white raw silk — directly to weaving and knitting mills and textile manufacturers worldwide. We stock four varieties of raw silk yarn, so you can source the exact yarn your production needs from a single supplier: 20/22 denier white raw silk, natural dupion silk yarn, luxury silk yarn and GOTS-certified organic silk.
Raw silk begins with the Bombyx mori silkworm, which feeds only on mulberry leaves and spins a single continuous filament. Each cocoon is boiled to soften the sericin gum, then carefully unwound into a thread of 600 to 900 metres. Multiple filaments are then twisted together into the strong, even yarn we ship — which is why raw silk is measured in denier (20/22D), not momme like woven cloth.
If you are a fashion designer or brand sourcing raw silk for weaving, hand and evenness are what separate a smooth production run from a costly one. Silk is prized for its high breathability, natural moisture-wicking and surprising strength, with low elasticity and little tendency to pill. Our raw silk yarn export from China is produced to GB/T 1797-2008, with moisture controlled below 11% and packaging sized for containerised, export-ready bales.
Three varieties of raw silk yarn
We stock three varieties of raw silk yarn from a single Yizhou source, so you can specify the exact yarn your production needs.
20/22D White Raw Silk Yarn
A filature silk measured at the delicate 20–22 denier range for ultimate consistency and fineness. It is the technical benchmark of modern reeling, with every metre checked for uniformity, and the bright, clean white reflects the fine mulberry cocoons it is drawn from. Weavers value this specific denier for its ability to create intricate patterns without adding bulk, and it is the secret ingredient in the world's finest silk crepes — a high-performance yarn for the most demanding weaving, knitting, embroidery and saree projects.

Natural Dupion Silk Yarn
The natural, unbleached and un-dyed state of dupion silk, with a warm, earthy tone that reflects the actual color of the silk cocoon before processing. It is thick and full of character, with prominent slubs that weave into a beautiful, seemingly random pattern. It is the quintessential choice for interior design — especially curtains and lampshades that need to diffuse light — and its natural hue brings a grounding, organic feel to any room, celebrating the imperfections of the natural world.

Luxury Silk Yarn
Curated from the finest batches of the silk harvest for a superior experience, with every strand selected for exceptional length and brilliant white sheen to ensure a high-gloss result. It is treated with extra care during spinning to preserve the integrity of the delicate silk proteins. This yarn is made for statement pieces — garments meant to be noticed for their sheer quality and radiance — draping with a heavy, liquid-like grace that is the hallmark of true high-end luxury silk.

Frequently asked questions
What varieties of raw silk yarn do you supply?
We supply four varieties of raw silk yarn from a single source: 20/22 denier white raw silk (the workhorse for crepe and satin), natural dupion silk yarn (thick, slubbed and unbleached for textured weaving and interior textiles), luxury silk yarn (1-ply, 20 denier, selected from the finest batches for statement pieces), and GOTS-certified organic silk (verifiable organic status for brands with organic sourcing requirements).
What is 20/22D white raw silk yarn?
20/22D white raw silk is a filature silk measured at the 20–22 denier range for ultimate consistency and fineness. It is the standard for silk crepes and satins — weavers value it for creating intricate patterns without adding bulk, and dyers prize its pure white base for accurate color matching.
What is natural dupion silk yarn?
Natural dupion silk yarn is the unbleached, un-dyed form of dupion — left in its natural state with a warm, earthy cocoon tone. It is thick and full of character, with prominent slubs that create a beautiful, random pattern when woven. It is the classic choice for interior textiles such as curtains and lampshades.
What is luxury silk yarn?
Luxury silk yarn is curated from the finest batches of the silk harvest — every strand selected for exceptional length and brilliant white sheen. It is a 1-ply, 20 denier yarn treated with extra care during spinning to preserve the silk proteins, designed for statement pieces where quality and radiance are the point.
How is raw silk made?
Raw silk comes from the Bombyx mori silkworm, which feeds on mulberry leaves and spins a single continuous filament. Each cocoon is boiled to soften the sericin gum, then unwound into a thread of 600–900 metres. Several filaments are twisted together into the strong, even yarn that is wound and shipped.
What is the difference between denier and momme?
Denier measures silk yarn weight — our 20/22D raw silk is 20/22 denier. Momme measures the weight of woven silk fabric (e.g. 19 momme). You use denier when buying yarn, and momme when buying cloth.
What are the key properties of mulberry raw silk?
Mulberry raw silk is highly breathable and naturally moisture-wicking, with surprising tensile strength, low elasticity and little tendency to pill. These properties make it ideal for warp and weft that must hold tension and take color evenly.
What is the minimum order quantity (MOQ) for raw silk yarn export?
Raw silk is sold by weight, not by the meter. There is no universal fixed MOQ — the reference minimum varies by variety (for example, dupion silk yarn is typically quoted around 10 kg and luxury silk yarn around 5 kg), and the final MOQ and any organic status are confirmed in the written quotation.
Can I get a raw silk yarn sample before bulk ordering?
Yes. Free mini fabric swatches may be supplied after availability is confirmed, and full-size samples are chargeable. See our Sample Service Policy for details.
