Sandwashed silk — also sold as washed silk — is finished by tumbling the cloth with fine abrasive, which lifts the surface fibres and kills the glare. What is left is a matte, slightly peachy hand that looks like silk and behaves like a much more forgiving fabric.

It is the finish to specify when you want silk that does not look "dressy". A 16 mm washed crepe de chine makes sleepwear and relaxed shirts; a 30 mm washed faille makes a soft, unstructured jacket; a 19 mm washed charmeuse keeps the drape of satin without the mirror finish.

At a glance

  • Matte, peach-skin surface — no specular highlight, photographs softly
  • Softer and slightly thicker in the hand than the same weight in standard finish
  • Hides needle marks and seam impressions far better than polished satin
  • Washed finish is a dye-house process, so custom colours are made to order

How Sandwashed Silk is woven

Structure: Base weave + abrasive/enzyme wash

Interlacing diagram — warp ends vertical, weft picks horizontal. A dark cell is a point where the warp passes over the weft.

warp over weftweft over warp

Sand-washed silk is not a separate weave — it is a finish applied to a woven base, most often charmeuse or crepe de chine. The cloth is tumbled with abrasive media or treated enzymatically until the surface filaments are raised and broken.

The finish removes the lustre and leaves a sueded, peach-skin hand and a relaxed drape. It also softens the creasing behaviour: sand-washed cloth looks deliberately rumpled rather than accidentally creased, which is a large part of why designers specify it.

Understanding the structure is the cheapest way to predict behaviour: the length of the float decides the lustre and the snag resistance, and the twist in the yarn decides how much the cloth creases. If you are choosing between two families, the weight chart and the fabric selector filter on both.

Weights we weave — and what each one is for

Momme fixes the price, the opacity and the drape. The table below is the range we actually quote for Sandwashed Silk. The exact weight and width are confirmed in writing on every quotation.

What Sandwashed Silk Fabric is used for

Typical applications in this family are sleepwear and pyjamas, relaxed shirts, soft unstructured jackets, washable bedding, scarves, garments that must not look shiny in photos. Each link opens the buying guide for that application, with the weight windows we recommend and the fabrics our clients actually order.

Sandwashed Silk Fabric vs Standard Charmeuse

Same yarn, different finish. Choose washed when you want drape without shine, or when the garment will be photographed under hard light.

Cutting and sewing this weight

Silk is not difficult to sew, but it punishes the wrong needle. The parameters below are the ones our clients converge on for this weight band; test on an offcut first, because a needle size that is fine for one finish will pick threads in another.

ParameterWhat we recommend for 16–40 mm (≈ 69–172 gsm)
Machine needle70/10 to 80/12, fresh needle every few garments
Stitch length10–12 stitches per inch (2.5 mm)
ThreadFine mercerised cotton, silk-finished polyester, or spun silk — matched to the shell so the seam does not pucker
Interlining / support25–40 gsm, or a hair-canvas chest piece for a structured bodice
Pressingsilk setting with steam, always through a cloth; do not glaze a satin face
Pre-shrinkingcold soak, or have the piece steam-shrunk before laying the pattern
Seam finishFrench or hairline seam on anything sheer; overlocked and turned on opaque weights
  • Cut single layer. Silk shifts, and a folded lay gives you two panels that are not mirror images.
  • Pin inside the seam allowance only, with fine glass-head or silk pins — a pin hole through charmeuse or a satin face is permanent.
  • Use a fine, well-twisted thread. A thick thread in a fine needle leaves a visible channel and puckers the seam.
  • Mark the straight grain on every panel before you lift it off the table. On a bias-cut garment the grain line is the whole design.
  • French seams or hairline seams on anything sheer: a plain turned seam shows as a dark line through the cloth.

How much sandwashed silk to order

Planning quantities, from standard block patterns. Figures are for a plain layout with no pattern repeat to match.

Garment or itemAt 114 cm widthAt 140 cm widthNotes
Scarf 90 × 90 cm1.0 m1.0 mIncludes a narrow hand-rolled hem; allow more for a wide hem or a border print
Camisole or shell top1.2 m1.0 mBias cut; add 15% if the design is cut on the true bias
Blouse or shirt2.0 m1.6 mStraight body, set-in sleeve; more for a gathered or oversized body
A-line skirt1.5 m1.2 mAbove-knee; a full circle skirt needs roughly double
Straight dress2.8 m2.2 mKnee length, no train, bodice and skirt from one length
Bias slip dress3.2 m2.6 mBias layouts waste more; buy the length the pattern states, not the flat measure
Evening gown with train5.5 m4.5 mFloor length; fitted bodice plus a trained skirt needs a second length to match
Standard pillowcase 50 × 70 cm0.7 m0.7 mEnvelope closure; pair two if the fabric has a directional nap
Curtain panel, 2× fullness—3.0 m per metre of dropRule of thumb: drop × 2 to 2.5 for pencil pleat, plus hem and heading allowance

These are planning figures from standard block patterns, not a cutting guarantee. They assume no pattern matching and no nap. Add 10–15% for a large repeat or a one-direction print, and add your shrinkage allowance before you order. If a program is costing on metres, send us the marker and we will quote against the actual consumption.

What to check before you cut

Every roll is inspected before dispatch, but cloth is a natural product and dye lots vary. These are the eight checks worth making at goods-in — they take two minutes and they are the difference between a claim and a write-off.

CheckHow to do itWhat is a problem
Shading, side-to-side and end-to-endLay the cloth folded end to end and across the width under daylight or a D65 lamp.Any visible step between the centre and the selvedge, or between the start and the end of a roll.
Bowing and skewingSquare the cloth on a table and measure the diagonal, or check a printed repeat against the selvedge.The weft running more than a few centimetres off square across the width — it distorts every panel cut from it.
Slubs, thick and thin placesExpected and structural in dupioni and shantung; check for consistency across panels.A slub count that varies sharply between panels of the same garment.
Broken ends, floats, snagged yarnsHold the cloth up to a light source and scan across the width.Any broken filament on a satin face — it will run under tension.
Crease marks and chafe marksUnroll flat and look across the surface at a low angle.Permanent creases pressed into a finish, or abraded lines where the roll has rubbed in transit.
Soiling, oil and water marksScan both sides; some marks only show on the reverse.Any spot. Silk stains cannot be safely spot-cleaned before dyeing.
Width short against the ticketMeasure the usable width between the selvedges, excluding the pin-holes.Less usable width than the quotation states — markers are often drawn tight.
Hand and finish against the approved sampleCompare to the bulk sample you signed off, in the same lighting.A softer or firmer hand, or a difference in lustre. Finishing drifts between dye lots.

Every roll we ship is inspected before it leaves, and any piece with a defect is cut short and the metrage credited rather than passed on. Even so, check the cloth before it goes under the knife: once a piece is cut it is accepted. Report anything within seven days of delivery with the roll number.

Ordering: minimums, colours and finishing

Stock colours are available from 1 metre, which makes sampling practical. Custom dyeing starts at 40 metres per colour with a lab dip approved before bulk; digital printing starts at 40 metres per design after a strike-off. Widths are 114 / 140 cm, and the momme tolerance is stated on the quotation rather than assumed.

For a production program, approve a one-metre cut in the bulk colour before the roll is dyed — screen colour and cloth colour are not the same thing, and sandwashed silk fabric is a family where a shade difference shows across a seam.

Care and handling

Hand wash cold with a pH-neutral silk detergent, or dry clean. Do not soak or wring; roll in a towel and dry flat away from direct sun. Press on the reverse with a cool iron through a cloth. Expect 3–5% shrinkage on the first wash, so pre-shrink before cutting a production run.

Frequently asked questions

What does sandwashed mean in silk?

Sandwashing is a mechanical finish: the woven cloth is tumbled against a fine abrasive so the surface fibres break and bloom. The result is a matte, peach-like hand with reduced lustre and a slightly fuller body — the same silk, minus the shine.

Is sandwashed silk more durable?

The finish softens the surface, which makes seam impressions and needle marks less visible, and the bloomed fibres hide light abrasion. It still needs the same gentle washing as any silk; the advantage is cosmetic and tactile rather than a change of fibre.

Can sandwashed silk be printed?

Yes, but print reads softer and more matte than on a polished base. Designers choose it deliberately for a vintage or watercolour look; if you need crisp, saturated graphics, print on standard crepe de chine or twill instead.

How do I know this is real mulberry silk and not polyester satin?

Ask for a burn test on a cutting: mulberry silk burns slowly, smells like burning hair, and leaves a brittle black bead that crushes to powder. Polyester melts, smells sweet-acrid and leaves a hard bead. We supply 100% mulberry silk and state the composition on every quotation; if you need formal confirmation we can arrange third-party fibre analysis on the bulk.

What width do the rolls come in, and can I get a wider one?

Standard widths are 114 cm and 140 cm, and the usable width excludes the selvedge. Wider widths are woven to order on a minimum quantity. If a marker needs a specific width, tell us before quoting — the price is calculated on the width as well as the weight.

How much shrinkage should I allow?

Silk typically relaxes 3–8% on the first wet treatment, more on washed finishes and less on a fabric that has already been sand-washed. The safe approach is to pre-shrink a full length before cutting a production run, or to have the piece steam-shrunk. Do not guess: the allowance belongs in the marker, not in the pattern.

Can you match a colour I send you?

Yes. Send a physical swatch or a Pantone reference and we dye a lab dip for approval before bulk. Custom colours start at 40 metres per colour. Screen and monitor colours are not a reliable reference — a photograph of a fabric is two colour conversions away from the cloth.

What is the lead time?

Stock colours dispatch in a few working days. Dyed-to-order runs need the lab dip approved first, then dyeing and finishing; printed runs need a strike-off approved before bulk. The quotation carries the confirmed date for your quantity, and we would rather quote a longer date and meet it.

Do you ship samples, and can I order just one metre?

Yes. Stock colours are available from one metre so you can test drape, dye uptake and washing before committing. We post swatch cards worldwide; tell us which families you are comparing and we will send the relevant colours.
