When sourcing woven fabrics for bedding, home textiles, or technical applications, procurement teams must evaluate the weft insertion technology used by the weaving mill. The two primary high-speed shuttleless systems are the water-jet loom and the air-jet loom. While both achieve high productivity compared to legacy rapier or projectile machines, their mechanical transport mediums—pressurized water versus compressed air—dictate which fiber types and yarn constructions each can efficiently run.
For converters and textile brands purchasing greige polyester, selecting the correct loom technology directly impacts fabric cleanliness, weaving consistency, and unit costs. Continuous-filament synthetic programs require a different approach than spun cotton programs.
Loom comparison: waterjet vs air-jet
| Property | Waterjet loom | Air-jet loom |
|---|---|---|
| Weft insertion medium | High-pressure water jet stream | High-pressure compressed air jet |
| Optimal yarn family | Hydrophobic continuous filament (flat filament & DTY) | Hydrophilic spun yarns (cotton, cotton blends, viscose) |
| Running speed & output | Very high speed; low electrical power per pick | High speed; substantial energy demand for air compressors |
| Shed cleanliness & fly | Near-zero fly or lint; clean water-lubricated shed | Spun fibers shed dust and fly; requires suction filtration |
| Fiber moisture behavior | Water drains freely without penetrating hydrophobic polyester | Water would swell natural fibers and create persistent water spots |
| Typical fabric products | Polyester greige sheeting, duvet covers, curtain grounds | Cotton sheeting, poplin, shirting, denim, bottom-weights |
| Minimum order volume | Stock greige: no minimum; custom weave: 5,000 m | Sourced from cotton mills; varies by producer |
| Buyer procurement rule | Specify waterjet greige for 100% filament polyester | Confirm loom type with suppliers for cotton-rich programs |
When waterjet weaving fits your program
Waterjet weaving represents the manufacturing standard for programs engineered from 100% continuous-filament polyester yarns:
- Hydrophobic continuous-filament polyester: Waterjet insertion employs a micro-nozzle to shoot a metered droplet stream that carries the weft across the warp shed. Because polyester is non-absorbent, flat filament and draw-textured yarn (DTY) shed water instantaneously without fiber swelling, shrinkage, or tension loss during high-speed insertion.
- Superior production economy and low energy consumption: Pumping liquid water to high pressure consumes only a fraction of the kilowatt-hours needed to compress air at industrial volumes. For large-scale polyester greige orders, waterjet weaving delivers a structural manufacturing cost advantage that translates directly into lower square-meter fabric prices.
- Zero fly and exceptional surface cleanliness: Continuous polyester filaments running in a wet shed release negligible lint or airborne debris. This absence of airborne fiber contamination ensures a pristine greige cloth surface, reducing pick-up defects during rotary disperse printing or clean heat-setting.
Waterjet weaving is the default choice for polyester bedding grounds, duvet covers, peachskin base fabrics, and curtain backings.
When air-jet weaving fits your program
Air-jet weaving is engineered for natural fibers, spun synthetic blends, and cotton-rich constructions:
- Hydrophilic spun yarns: Air-jet looms utilize compressed air released from relay nozzles across a profiled reed to propel the weft yarn. Because the insertion medium is dry, moisture-sensitive fibers such as carded or combed cotton, linen, modal, and spun rayon pass through without wetting, swelling, or losing structural rigidity.
- Cotton sheeting and shirting: For sheeting programs specifying cotton or cotton/polyester intimate blends, air-jet machines provide the high insertion speeds necessary for competitive pricing in shirting, poplin, and high-thread-count cotton percales.
- Why air-jet is inefficient for filament polyester: While air-jet looms can physically insert textured polyester filament, the massive electrical load of the air compressor plant makes it an uneconomical choice when dedicated waterjet capacity is available.
When sourcing cotton-rich products, buyers should confirm air-jet weaving directly with their dedicated cotton spinning and weaving partners.
Waterjet weaving and mill parameters
Weaverine operates 650+ high-speed waterjet looms across its production facilities (origin Zhejiang Changxing, weaving base Wuhe, Anhui). Our sheds weave waterjet polyester greige exclusively; we do not operate air-jet equipment. We provide this comparative analysis so brand buyers understand how to write technically precise purchase orders across global supply networks.
Our verified manufacturing parameters include:
- Loom-state greige width: 160 cm to 330 cm directly from our waterjet looms.
- Usable finished width: 150 cm to 315 cm following downstream scouring, dyeing, and stenter relaxation.
- Greige fabric weight: 55–120 g/m² in unfinished loom state.
- Finished fabric weight: 60–140 g/m² depending on dyeing, brushing, or coating pickups.
- Weave structures: Plain weave, twill weave, and dobby shedding for satin stripes and small dobby checks. Jacquard is not woven at this mill.
- Order minimums: Stock greige specifications have no minimum order quantity (subject to ongoing warehouse availability). Make-to-order custom widths, weights, or dobby patterns require a 5,000-meter production floor.
What to specify on the RFQ or purchase order
To eliminate communication errors between purchasing offices, weaving sheds, and finish converters, include these technical parameters on every inquiry:
- Procurement rule: For 100% filament polyester programs, explicitly state waterjet greige to lock in production efficiency. For cotton-rich programs, confirm loom technology with the designated mill.
- Fiber composition & yarn type: 100% polyester continuous filament (specify flat filament or DTY; virgin or GRS-certified recycled).
- Loom specification: Waterjet loom greige.
- Weave structure: Plain (1/1), twill (e.g., 2/1, 2/2), or dobby (specify satin stripe band width if applicable).
- Width requirements: State both target loom-state greige width (e.g., 240 cm) and minimum usable finished width (e.g., 230 cm).
- Weight targets: Clearly distinguish between greige GSM and finished GSM, indicating the test standard (such as ISO 3801).
- Downstream finishing route: State whether the greige will undergo disperse dyeing, rotary printing, peachskin sanding, or flame-retardant coating.
- Order volume: Total required volume in linear meters.
