Air-Jet, Rapier or Shuttle: What the Loom Type Means for Your Fabric
The loom type — air-jet, rapier or shuttle — decides how the weft is inserted, and through that the selvedge you receive, the defect profile to inspect for, and which constructions run economically. Air-jet is the workhorse for long runs of standard cotton constructions; rapier handles delicate, fancy or stretch wefts; shuttle survives for the woven closed selvedge some end uses demand. It is a routing decision, not a quality grade.

What changes for the buyer with loom type?
Three things on the cloth you receive trace directly to the loom: the selvedge (woven closed, tucked-in, or fringed — set by how the weft is carried), the defect profile (each insertion method fails in its own characteristic ways), and the economics of your construction (a weft the insertion method handles badly weaves slowly and expensively, or not at all). Buyers treat loom type as a quality grade — shuttle meaning old and bad, air-jet meaning modern and good. It is not a grade: each type is the right answer to a different construction and end use, which is why all three are still in service.
How do air-jet, rapier and shuttle looms compare?
| Air-jet | Rapier | Shuttle | |
|---|---|---|---|
| Weft insertion | Compressed-air jets carry the weft across — no gripper touches the yarn | A gripper (rapier) carries the weft across positively, end to end | A shuttle carries a pirn of weft back and forth as one continuous yarn |
| Speed & run economics | The fastest of the three on standard constructions — the volume workhorse for long runs | Slower than air-jet, but runs wefts air cannot carry reliably | The slowest by a wide margin — economic only where its selvedge or character is the point |
| Weft range | Best with regular, uniform staple and filament wefts that ride an air stream | The widest range: fancy, slub, elastane, chenille, heavy and delicate wefts | Handles most wefts, within its speed — the range mattered more before rapier existed |
| Selvedge | Cut with a tucked-in or leno edge — the inserted weft is trimmed each pick | Cut with a tucked-in or leno edge, like air-jet | A woven closed selvedge — the weft turns back on itself at each edge |
| Characteristic defects to inspect for | Weft insertion faults — missing or short picks, blown weft — and stop marks | Weft loops and pulled picks at handover, tension marks on delicate wefts | Pirn-change marks, shuttle traps and smashes, slower-run tension bars |
| Best suited to | Long runs of standard cotton and blend constructions — sheeting, poplin, twill | Fancy and technical wovens, stretch wefts, short flexible runs | Selvedge-critical cloth — classically selvedge denim — and speciality character |
Across our partner mills all three loom types are available, and air-jet is the most preferred route for standard greige constructions — the volume, speed and consistency economics favour it wherever the weft allows.
How do you identify the loom from the selvedge?
The selvedge is the loom's signature, and reading it is a thirty-second diagnostic on any roll or swatch:
- 1. Look at the edge yarns. A smooth, continuous edge where the weft visibly turns back into the cloth is a woven closed selvedge — shuttle.
- 2. Look for tucked ends. A firm edge with short weft tails folded back into the last few warp ends is a tuck-in selvedge — a shuttleless loom (air-jet, rapier, projectile or water-jet).
- 3. Look for a gauze-like binding. A pair of crossing threads locking trimmed weft ends is a leno selvedge — also a shuttleless loom. The selvedge tells you shuttle versus shuttleless; it does not identify which shuttleless type.
- 4. A visible fringe of cut ends means the weft is trimmed at the edge — again a shuttleless loom, before the edge finishing.
- Air-jet and rapier cannot be reliably separated by selvedge alone — both trim and secure the weft. If the distinction matters to your programme, ask; do not deduce.
Why is the width you want not available on every loom?
Because a width limit is a property of the individual machine installed, not of the loom family. Each loom is built to a working reed width, and a mill's fleet is a specific inventory of machines at specific widths — so "can rapier weave my width?" has no general answer, and any published maximum-width table is describing someone's fleet, not a law of the technology. The honest procedure is to state the finished width you need and let the sourcing partner confirm which partner-mill route reaches it; weaving wider than needed and cutting down is sometimes the economical answer, and that too is a route decision, not a loom-family fact.
Which loom suits which end use?
- Standard cotton and blend greige at volume — sheeting, poplin, shirting, twill, drill: air-jet, for run speed and consistency; it is the most preferred route across partner mills wherever the weft allows.
- Stretch wefts, slubs, fancy and technical wefts — anything an air stream carries badly: rapier, whose gripper handles the weft positively.
- Selvedge-critical cloth — where the woven closed edge is a feature of the product, classically selvedge denim: shuttle.
- Undecided? Specify the cloth — construction, weft character, selvedge requirement — and let the loom follow. Specifying the loom first, without a reason on the cloth, only narrows the routes that can quote.
What should you ask when the loom type is not stated?
- "What selvedge will I receive?" — the answer identifies the loom family and tells you what your cutting room will handle.
- "Which loom route will my construction run on, and why?" — a reasoned answer names the weft or selvedge driver; an evasive one is worth noting.
- "Can this route reach my finished width?" — per machine, per mill; never assume from the loom family.
- "Does the defect profile change my inspection?" — the characteristic-defect column above is what any agreed body inspection should be looking for.
How that inspection actually runs on a greige lot — headers from every roll, matched and checked — is covered in how greige fabric is inspected.

Frequently asked questions
What is the difference between air-jet and rapier looms?
The weft carrier. Air-jet looms insert the weft on compressed air — fastest on standard, uniform wefts. Rapier looms carry the weft with a gripper — slower, but positive control handles stretch, slub, fancy and delicate wefts air cannot carry reliably. Both produce a cut, secured selvedge.
What does the selvedge tell me about the loom?
A woven closed selvedge, where the weft turns back at the edge, means a shuttle loom. A tucked-in, leno or fringed edge means a shuttleless loom — air-jet or rapier, which selvedge alone cannot reliably separate. It is the quickest loom diagnostic a buyer can run on a swatch.
Is shuttle-loom fabric better quality?
Not as a rule — loom type is not a quality grade. Shuttle looms survive because their woven closed selvedge is a genuine product feature for some end uses, classically selvedge denim, at much slower speeds. Quality is set by the construction, the yarn and the standard the lot is inspected to.
What is the maximum fabric width a loom can weave?
There is no general figure — the limit is a property of the individual machine installed, not the loom family, and every mill fleet differs. State the finished width you need and have your sourcing partner confirm which partner-mill route reaches it, per enquiry.
Which loom type do Burhan partner mills use?
All types are available across partner mills, and air-jet is the most preferred route for standard greige constructions — its speed and consistency suit long runs. Rapier and shuttle routes are used where the weft or the selvedge requirement calls for them.
On typical values: comparisons on this page describe the technologies in general; the loom route, achievable width and defect profile for a specific order are properties of the partner mill's installed machines and are confirmed per enquiry. Physical swatches and approved specifications override anything illustrated here. Burhan Enterprises is a sourcing and export partner and coordinates through partner mills and processing units.
