Dual-Jet
A water-jet weaving method that puts two wefts—or two yarns—into one pick, so the cloth is usually loftier than single-jet, and often shows a two-tone face.
Dual-jet is a way of weaving on a water-jet loom, not a colour and not a print. A single-jet loom fires one weft across the shed; a dual-jet fires two — either two ends of the same yarn or two different yarns — in the same pick. That extra weft opens the cloth a little, so the hand and the face change, and it is a pick note on the PO rather than a weave family.

What dual-jet means
Dual-jet is a way of weaving on a water-jet loom, not a colour and not a print. A single-jet loom fires one weft across the shed. Dual-jet fires two—either two ends of the same yarn, or two different yarns—in the same pick. That extra weft opens the cloth a little, so at the same yarn count it usually feels loftier and a touch thicker than single-jet greige.
| Single jet | Dual jet | |
|---|---|---|
| Wefts per pick | One | Two |
| Cloth effect | Standard hand and cover | Loftier, slightly more open |
| Face | Single yarn face | Can be two-tone |
| PO language | Standard pick | Dual-jet pick note |
If those two yarns differ in lustre, denier, or colour, the face takes on a two-tone or heathered look. The effect moves as you turn the swatch in the light, which is why buyers often handle the cloth before they ask about weight. Nothing is sitting on the surface the way a pigment or disperse print would.
Mills use it on volume polyester bedding because the loom runs faster at the same reed width. A softer hand does not automatically mean a tougher cloth: wash, pilling, and shrinkage still come down to the yarn, the GSM, and the finish. When a hotel program wants a crisp, tightly interlaced sheet, single-jet is still the more stable construction.
On the order, dual-jet is a construction note on greige or on a finished program—not a catalogue SKU and not a fibre. You can leave it loom-state, piece-dye it, yarn-dye it, brush it as peachskin, or print it later. Call out dual-jet versus single-jet the same way you would call out width and GSM. A photo will not settle a two-tone face—ask for a swatch and look at it under more than one light.
Common questions
What is dual-jet weaving?
- A way of weaving on a water-jet loom where two wefts are inserted in the same pick — either two ends of the same yarn or two different yarns. A single-jet loom fires one weft across the shed. The extra weft opens the cloth a little, so the hand and the face change.
Is dual-jet a weave or a colour?
- Neither. It is a pick note — a way of inserting the weft — not a weave family and not a colour or a print. The weave is still plain, twill or whatever the construction is; dual-jet changes how many wefts go in per pick, not the interlacing plan.
What does dual-jet do to the fabric?
- It opens the cloth slightly and can produce a two-tone face when the two wefts are different yarns. That changes the hand and the cover, which is why it is specified for programmes where a loftier or two-tone effect is wanted rather than a standard single-jet ground.
How do I specify dual-jet on an order?
- As a pick note alongside the construction: the weave, the GSM, the width, and then the dual-jet instruction with which yarns go in. A PO that says only 'dual-jet' leaves the mill choosing the yarns, and the yarns are what decide whether the face is two-tone.
