What Each Machine Actually Produces
A weaving machine interlaces two sets of yarn — the warp (running lengthwise) and the weft (running crosswise) — at right angles. The result is a woven fabric: dimensionally stable, low-stretch, and with a clearly defined grain. Denim, shirting, suiting, canvas, sarees, upholstery fabric, and most industrial textiles are woven. Woven fabric holds its shape under tension, which is why it is used wherever structure matters more than stretch.
A knitting machine forms fabric by pulling loops of yarn through previous loops. The result is a knitted fabric: inherently stretchy, breathable, and conforming to body shape. T-shirts, hosiery, underwear, sportswear, knitwear, and most jersey fabrics are knitted. That elasticity is a feature, not a defect — but it also means knitted fabric does not substitute for woven fabric in applications where dimensional stability is required, such as structured tailoring or technical filtration cloth.
Neither machine type is superior in general. They produce fundamentally different materials. If your confirmed orders, target customers, or existing product catalogue call for woven fabric, no used knitting machine — regardless of brand, gauge, or price — can fulfil them. Fix the product type first, then evaluate machines.
Matching Machine Type to Your Product Line
Work through this product-first checklist before you compare any used listings.
Buy a used weaving machine if your product line includes:
- Shirting, suiting, or formal dress fabric — these require the flat, stable structure that only weaving produces.
- Denim — woven twill construction is definitional to the fabric; there is no knitted equivalent that passes as denim.
- Sarees, dress material, or traditional handloom-style fabric — even power-loom versions replicate woven structure.
- Canvas, tarpaulin, or industrial fabric — load-bearing applications require zero-stretch woven construction.
- Upholstery and furnishing fabric — dimensional stability under repeated stress rules out knitted substrates.
- Technical textiles for filtration, geotextiles, or medical drapes — tight, stable weave geometry is typically a specification requirement.
Buy a used knitting machine if your product line includes:
- T-shirts, polos, and jersey wear — the standard single-jersey or piqué constructions are knitted, not woven.
- Hosiery, socks, and stockings — these are produced on specialist circular or flat-bed knitting machines.
- Underwear and innerwear — stretch comfort fit requires knitted construction.
- Sportswear and activewear — four-way stretch and moisture-management performance fabrics are typically warp-knitted or circular-knitted.
- Knitwear and sweaters — flat-bed knitting machines produce panels that are then linked into garments.
- Blankets and fleece fabric — circular knitting followed by raising or brushing produces standard fleece.
When both types appear in your product line
Some manufacturers produce both woven and knitted goods — a garment unit that makes formal trousers (woven) and casual T-shirts (knitted), for example. In that case, you need both machine types. Buying one machine and expecting it to cover both product categories is not feasible regardless of attachments or accessories. Prioritise the product category that generates the majority of your confirmed order volume and acquire the corresponding machine first.
Secondary Factors That Affect the Used Purchase
Once the machine type is settled, evaluate used machines on these practical factors.
Weaving machines: what to assess used
- Loom type — shuttle, rapier, or air-jet. Shuttle looms are the simplest and cheapest to maintain but are slower. Rapier looms handle a wider range of yarn types. Air-jet looms run at high speed but require a reliable compressed-air supply and are less economical on heavier yarns.
- Reed width — the working width of the loom in centimetres. It must match your fabric width requirements. Retrofitting is not straightforward.
- Dobby or jacquard head — a dobby head controls up to around 24 pattern shafts; a jacquard head controls individual warp threads and is used for complex woven patterns. Verify the head type against your design requirements before buying.
- Mechanical condition of the shedding mechanism — the component that separates warp threads to create the space for weft insertion. Worn cams or damaged heddles directly affect fabric quality and are not cheap to replace.
- RPM rating and actual running speed — a machine listed at 400 rpm that has been running at 250 rpm due to unresolved vibration is worth less than its headline speed suggests. Ask for the actual production rate in metres per shift.
Knitting machines: what to assess used
- Machine gauge — the number of needles per inch. Finer gauge (higher number, e.g. 28 gauge) produces finer fabric; coarser gauge (e.g. 12 gauge) produces thicker fabric. Gauge is fixed to the cylinder and cannot be changed; it must match your yarn count.
- Circular vs. flat-bed — circular machines produce tubular fabric in continuous rolls and are standard for jersey and hosiery. Flat-bed machines produce flat panels and are used for shaped knitwear and fully-fashioned garments. They are not interchangeable.
- Needle condition — knitting needles are consumable components but worn or broken needles in a used machine indicate either heavy use or poor maintenance. Count broken needles in any machine you inspect in person and factor replacement cost into the price.
- Number of feeders on a circular machine — more feeders mean higher output. A 90-feeder machine produces significantly more fabric per hour than a 48-feeder machine of the same diameter.
- Electronic vs. mechanical patterning — older mechanical pattern wheels are simple to operate and maintain but are limited in pattern complexity. Electronic control allows faster pattern changes, which matters if you run short, varied production runs.
Factors that apply to both
- Spare parts availability for the specific brand and model — a machine with no local parts supply will sit idle when a component fails. Confirm parts are available before committing, not after.
- Power supply compatibility — weaving machines and industrial knitting machines are typically three-phase. Confirm your facility's supply matches the machine's requirement before transport.
- Age and hours of use — hour meters can be reset; cross-reference machine age, wear patterns, and maintenance records. A 15-year-old machine with genuine low hours in a well-maintained factory is often preferable to a 5-year-old machine run into the ground.
- Manufacturer support and local service technicians — for programmable or electronic machines, verify that someone in your area can service the control system.
Where EasiMachines Helps and Where It Does Not
EasiMachines lists used weaving and knitting machines from sellers across categories, allowing you to search by machine type, browse available specs, and contact sellers directly. For a buyer who has already worked through the product-type decision above, the marketplace assists with finding relevant listings, comparing asking prices across available used inventory, and reaching sellers without going through a broker.
The platform does not certify machine condition, verify seller claims about running hours or maintenance history, or provide a guaranteed appraisal of what a specific used machine is worth. Automated price estimates on any used textile machine should be treated as a directional reference — a starting point for negotiation — not a certified valuation. Physical inspection, ideally with a technician who knows the specific machine type, remains the only reliable way to verify condition before purchase.
There is no EasiMachines-specific tool that determines whether a weaving machine or a knitting machine is right for your product line. That decision rests entirely on your product requirements, as described above. Once you know which type you need, the listings search is a practical next step.
Frequently asked questions
Can I convert a weaving machine to produce knitted fabric, or vice versa?
No. Weaving and knitting are mechanically distinct processes based on entirely different yarn-interlacement principles. There is no conversion path between the two. A machine built to weave cannot be modified to knit, and no attachment changes this. If your product line requires both, you need both machine types.
I want to produce stretch fabric. Does that automatically mean I need a knitting machine?
Not necessarily. Woven fabrics can incorporate stretch by using elastane (spandex) yarns in the weft or in both directions. This produces a woven stretch fabric — used in formal trousers and stretch shirting — that is still made on a weaving machine. If you need four-way stretch or the kind of recovery characteristic of sportswear and jersey, then knitted construction is the appropriate choice. The degree and direction of stretch required by your specific product determines the answer.
Is a used flat-bed knitting machine suitable for producing T-shirt fabric?
Typically, no. T-shirt fabric is produced on circular knitting machines, which output continuous tubular jersey fabric that is then cut and sewn. Flat-bed machines produce flat panels and are used for shaped knitwear — sweaters, cardigans, and fully-fashioned garments — where the shaping is built into the knitting rather than cut from fabric. If your product is cut-and-sew jersey garments, a circular machine is the correct type.
How significant is machine gauge, and can I change it on a used machine?
Gauge is one of the most important specifications on a knitting machine. It determines which yarn counts the machine can process and the weight and density of the resulting fabric. On circular knitting machines, the gauge is fixed to the needle cylinder — the main rotating component — and changing gauge requires replacing the cylinder entirely, which is a major cost, not a simple adjustment. When buying used, confirm the machine's gauge matches your yarn count before purchase.
What should I do if I cannot inspect a used textile machine in person before buying?
Request a video of the machine running at production speed, showing the fabric output, the control panel, and close-up footage of the needle bed or shedding mechanism. Ask the seller for the maintenance log, any recent service invoices, and the original manufacturer's manual. If the seller cannot or will not provide running footage and documentation, treat that as a significant risk factor, not a minor gap. For higher-value machines, it is worth engaging a local technician or agent to inspect on your behalf even when you cannot travel.
