Bulk Mekong Silk for Home Decor

For Thai and Vietnamese handwoven silk, mills typically quote a 5–10 m cut per colour or weave pattern, and prices are driven by three things: whether the weft yarn is hand-reeled (slightly irregular, more lustrous, pricier) or machine-reeled, the thread count per centimetre (lower counts give the loose, slubby ‘phae’ weave; higher counts give fine satin), and whether the dye is a standard solid or a custom-matched vat. Custom dye lots below roughly 30–50 m usually carry a surcharge because indigo, lac, or reactive dye vats have to be set up for a single run.

Fine slubs, tiny weft unevenness, and small ‘drawbacks’ (where the weaver turns a broken weft back into the cloth) are signatures of hand-reeled yarn on a wooden floor loom and should not be rejected; what you reject is uneven selvage tension, skipped picks, loom-oil stains, and dye bleeding along the fold lines. For Thai silk specifically, run the bolt at an angle and check that the two-tone shimmer — caused by contrasting warp and weft colours — stays consistent, because a patchwork effect usually means the weaver changed yarn mid-bolt. A quick burn test of a pulled thread is reliable: real mulberry silk smells of burnt hair and leaves crushable black ash, not a hard plastic bead.

Both Thai and Vietnamese silk are predominantly Bombyx mori mulberry, sometimes blended with the duller, more textured eri (or ‘peace silk’) for matka-style weights, with lụa tơ tằm in Vietnam and ‘phae’ or ‘mudmee’ weaves in Thailand being the most common constructions. Hand-reeled and hand-woven cloth has a crisper, more papery hand than machine-woven satin, and it will shrink 5–8% on the first wash, so cutting allowance and pre-shrinking protocols need to be agreed with the mill. Finishes range from un-degummed ‘gum-silk’ (still carrying sericin, very stiff) through to fully soft-degummed habotai; ironing should never exceed 150 °C or the remaining sericin will scorch yellow.

Custom solid-dye yardage usually takes around 4–6 weeks for lab dip approval plus 6–10 weeks for weaving, depending on whether you want a standard cross-weave or a supplementary-weft (brocade-style) motif. Garment OEM through a Vietnamese or Thai cut-and-sew house typically requires 50–100 pieces per style, with muslin-to-final sampling adding another 6–8 weeks. Be aware that motifs on traditional looms are limited to the weaver’s repertoire and yarn count — photographic or extremely fine designs will have to be shifted to a powerloom or substituted with a coarser supplementary-weft version.

Genuine Thai silk can carry the ‘ผ้าไหมไทย’ (Thai Silk) GI mark issued by Thailand’s Department of Intellectual Property, often combined with the Queen Sirikit Foundation’s silk-promotion mark, which together attest to Thai-origin mulberry silk and traditional hand-finishing. Vietnamese lụa Hà Đông and Mekong Delta silks do not yet have a single equivalent national GI, but they are increasingly traced through Vietnam’s OTOP (One Commune One Product) village codes and provincial craft-village certifications. For export to the EU, US, or Japan, an OEKO-TEX Standard 100 certificate is the most widely accepted independent proof that residual sericin, dye auxiliaries, and formaldehyde levels meet finished-textile limits.
