Start with the performance basis, not the merchandising language
A 280gsm cotton-poly stadium blanket sits between promotional throw and serious cold-weather merch. The commercial question is not whether it feels premium in hand, but whether it stays flat, keeps colour, and survives repeated laundering without edge distortion. At this weight, buyers are usually balancing four constraints: drape, wash recovery, freight cube, and retail price point.
Define every number on the same basis. If you quote 280gsm, state whether that is finished fabric weight after dyeing and finishing or greige cloth weight before construction. For buyer specs, finished weight is the only useful reference. If the mill cannot state the measurement basis, the quote is not comparable. GSM should be measured on finished, conditioned fabric, typically after 24 hours in standard atmosphere, and the buyer should ask whether brushing, washing, or coating is included in that weight. A brushed finish can add apparent loft without changing true fibre mass; a coated or bound edge can inflate finished-piece weight without changing body fabric gsm.
For this product family, the most workable construction is a woven cotton-poly blanket with a yarn-dyed face when stripes, checks, or club colours are required. A practical blend starting point is 60/40 cotton-poly or 70/30 cotton-poly. Cotton-rich versions usually give a drier, more natural hand and slightly better absorbency; polyester-rich versions generally dry faster and hold size better. Those are directional effects, not guarantees. Yarn count, sett, and finishing matter as much as fibre ratio. A loose 60/40 cloth can still shrink badly, while a well-set 70/30 cloth can hold dimensions well if the finishing is controlled. Use 60/40 when the channel is retail-led and hand feel matters more than wash recovery; use 70/30 when size stability, quicker drying, and lower crease load matter more than a natural touch. If the buyer has a hard price ceiling, blend choice should follow the wash target and finishing cost, not only the fibre cost.
If you need a related construction comparison, use the linked woven cotton-poly stadium blanket and jacquard stadium blanket articles in the related-slog list, not generic throw or fleece examples. The buying problem here is woven blanket control, not brushed fleece merchandising.
Lock the fabric spec in measurable terms
Write the fabric line like a purchase order, not a style note. A usable spec is: 280gsm finished weight, woven cotton-poly blanket, 60/40 or 70/30 blend, yarn-dyed if checks or stripes are required, flat woven or lightly brushed face only if approved, finished width and length to tolerance. If the buyer wants a softer hand, light brushing is acceptable, but it raises pilling risk and can shift shade perception across lots. Pick one primary construction path: hemmed woven blanket with a folded edge, or merrowed/overedge blanket with a visible stitched perimeter. Do not leave it ambiguous. If a decorative edge is needed, it should be stated as an allowed alternate, not a second default.
Weight tolerance should be explicit. A realistic production window is often +/-5% on finished gsm for a stable woven programme, with tighter control possible on narrow-width runs and looser control on small MOQ promotional orders. State the tolerance basis: finished, post-finishing, conditioned fabric. A mill quoting tolerance on greige cloth and finished goods is not quoting the same thing. For buyer comparison, ask for the gsm measured at 10 cm x 10 cm or equivalent lab sample method on conditioned fabric, and request the lab report rather than a verbal claim.
For size, a common commercial band is 130x170cm, 150x180cm, or 150x200cm, but the exact cut size must be paired with tolerance. A sensible starting point is +/-2cm on width and length for cut-and-sewn merchandise, with warp/weft skew checked against the approved sample. If the pattern is checked or striped, also define acceptable pattern match at the centre fold and side edges. A blanket can pass size and still look misaligned on shelf. For woven club-shop programmes, require the cut direction to be fixed so the stripe repeat falls consistently across the display face.
Use one construction term consistently throughout the PO. Call it woven cotton-poly blanket or yarn-dyed woven stadium blanket. Do not alternate between woven form, flat face, brushed face, and merrowed edge without fixing which surfaces are functional and which are decorative. Buyers can only compare quotes when the structure is stable.
Blend choice is about recovery, drying, and appearance retention
The blend ratio affects more than hand feel. Cotton content raises moisture uptake and can improve tactile comfort, but it also increases the risk of dimensional change if pre-shrink control is weak. Polyester content improves crease recovery, reduces drying time, and usually supports better lot-to-lot stability. That said, the response depends on yarn type, weave density, and heat-setting. A blanket with unstable finishing will misbehave regardless of whether the blend is 60/40 or 70/30.
If the programme is a seasonal retail line rather than heavy institutional washing, a 60/40 blend is usually a practical middle ground. If the buyer wants a slightly more natural touch and can tolerate modestly higher shrinkage risk, 70/30 can work. If the channel is price-sensitive and quick drying matters, increase polyester only if the hand feel still meets the retailer’s standard. Do not claim polyester-rich blends are automatically more durable or cotton-rich blends are automatically warmer; durability and thermal comfort depend on yarn diameter, construction compactness, and finishing. Use the following rule: choose 60/40 for retail presentation and softer handle; choose 70/30 for lower shrinkage risk and easier wash recovery; avoid pushing cotton above 70% unless the buyer accepts more shade and shrink variation after laundering.
Ask for a pre-production wash trial using ISO 6330. Write the method into the PO: for example, 5A domestic wash, 40C, standard reference detergent, line dry unless the care label requires tumble dry. Then set acceptance criteria. For many retail programmes, a practical target is dimensional change within +/-3% in warp and weft after the defined cycle count, but the exact threshold should follow the buyer standard. If the blanket will be sold as a brushed or napped product, add ISO 12945-2 with the number of cycles and minimum acceptable pilling grade written into the PO. For the most common retail wash claim, specify the wash programme fully: ISO 6330, 5A, 40C, 3.0 kg ballast load, reference detergent without optical brightener unless the care route demands it, tumble dry low only if the care label allows it, otherwise line dry. If the seller is using a different domestic route, require the exact machine class, load mass, detergent type, and drying condition to be listed on the test report.
For shade control, do not stop at “match approved sample.” Set a lab-dip rule: first bulk strike-off or lab dip must be approved against the physical standard under D65 and TL84 with visual pass/fail and Delta E recorded on the report. Bulk shade should stay within the buyer’s agreed delta, typically written as a measurable tolerance against the approved standard rather than a vague promise. For yarn-dyed stripes, require line-to-line shade consistency and acceptable side-to-side shade variation to be signed off before bulk cutting. Put the sign-off protocol in the PO: lab dip, strike-off, and first bulk piece all reviewed by the same buyer standard under D65/TL84; any Delta E tolerance to be agreed before production.
Merrowed edge needs a stitch spec, not a generic label
Merrowed edge is shorthand, not a complete spec. Buyers need to know whether the edge is a 3-thread overedge, a 4-thread merrow/overedge, or a decorative overlock with a separate cover line. They also need finished edge width, thread type, and the allowed waviness. Without that, two suppliers can both say merrowed edge and deliver very different products. Use merrowed edge as the primary term, and define overedge once as the factory-equivalent term in the tech pack. Do not keep switching between them.
For this category, a common starting point is a 4-thread overedge/merrow construction with a finished edge width around 6-8mm. For thicker cloth or a more decorative perimeter, the finished width may need to move wider, but that should be approved against a physical sample. Thread should be specified by construction and tex/denier, not just colour. For example: polyester overedge thread in the Tex 27-40 range is a plausible starting point for medium-weight woven blankets, but the exact choice should match seam bulk and needle penetration. Needle size, needle spacing, and stitch density matter as much as thread colour. A blind quote that says only “merrowed edge” is not enough for controlled factory pricing.
The main failure mode is edge torque after laundering. If the body fabric shrinks more than the thread chain, the border waves. If the edge stitches bite too hard into a loose weave, the perimeter fuzzes and can start to unravel at stress points. State a finished edge tolerance, for example edge waviness not exceeding 3mm over 30cm when checked flat after wash, if that is compatible with the buyer standard. Use that only if it matches the retailer’s own acceptance system; otherwise write the buyer’s tolerance, not a generic mill target. If a hemmed edge is selected instead, specify fold depth, stitch type, and corner treatment separately; do not assume the factory will standardise those details. A hemmed edge usually costs a little more in sewing time than a simple overedge and often gives a cleaner shelf look, while a merrowed edge is faster and more economical but exposes stitch appearance more clearly.
This is also where inspection discipline matters. Require a sealed edge reference sample, stitch density photos, thread colour approval, and a sample pulled from the first bulk run before the rest of the production is released. If the perimeter is decorative as well as functional, define whether the edge thread is matching, contrast, or tonal, and whether colour variation is acceptable at the seam junction.
Testing only helps if the method is fully written
Naming standards without the test conditions is weak sourcing. A buyer should insist on the exact test set-up, specimen prep, and acceptance limits. For this blanket category, separate the tests into mandatory compliance checks and optional programme tests so the factory does not treat everything as equally critical. Ask for mill test reports, not only external certificates. A certificate for one fabric lot does not validate the next lot unless the lot code, date, and retained sample are linked.
Mandatory for most retail programmes: ISO 6330 for wash durability, ISO 5077 for dimensional change, and ISO 105-C06 for wash fastness of dyed components. If the body surface is brushed or napped, add ISO 12945-2 for pilling. If the item has printed emblems, woven labels, or stitched badges, add colour and attachment checks for those components. ASTM D5034 is useful only if you specify whether you are testing body fabric tensile, edge seam strength, or both; for a woven blanket with a merrowed edge, the PO should say which orientation is being tested and which failure mode matters. For woven body fabric, a reasonable procurement ask is warp and weft tensile at three specimens each, with seam/edge strength only if the edge is load-bearing or exposed to tugging in use.
Optional programme tests: ISO 105-X12 for dry/wet crocking if dark colours or contrast stripes are a risk, ISO 105-E04 for perspiration fastness if the item is intended for spectator use in prolonged contact, and a light-fastness screen if the blanket uses saturated colours. If the design uses club colours outdoors, consider ISO 105-B02 for light fastness at the shade level the buyer actually expects. Do not mix mandatory compliance and optional brand-risk checks into one vague test cluster. If the buyer expects outdoor retail use, include a restricted-substance screen relevant to the market, such as azo dye screening or a regional chemical compliance review, rather than assuming generic textile conformity covers it.
A practical clause looks like this: condition specimens for 24 hours at standard atmosphere; test three specimens in warp and three in weft where applicable; wash 5 cycles at 40C under ISO 6330 method 5A with standard detergent; line dry unless the care label requires tumble dry; report dimensional change after cycle 1 and cycle 5; accept within the buyer’s shrinkage tolerance; colour change not below Grade 4 on the grey scale where applicable; pilling not below Grade 3-4 after the agreed cycles. That is operational. Simply saying “wash test target required” is not.
For edge and seam strength, specify whether the test specimen includes the finished merrowed perimeter or body fabric only. If the risk is fray-out at the border, the edge test matters more than the body tensile result. If the risk is fabric split, body tensile matters more. Write both only if both failure modes matter. If the blanket has a hemmed edge, add a seam-slippage check rather than a merrowed-edge claim.
Commercial spec sheet fields the buyer actually needs
A useful FOB sheet should be complete enough that three mills quote the same item. At minimum, include: fibre blend, finished gsm, weave form, cut size, edge construction, decoration method, colour standard, pack method, carton quantity, carton dimensions, gross weight, net weight, incoterm, lead time, overrun/underrun allowance, and AQL plan. If any of those fields are missing, price comparisons become unreliable.
For order planning, a typical MOQ for a custom woven stadium blanket is often in the 500-1,000 piece range per colourway or design, depending on loom setup and colour complexity. Smaller runs are possible, but the unit price rises quickly because dye, warp setup, and cutting loss are spread across fewer pieces. If the design uses multiple yarn-dyed colours, the MOQ may move up because warp planning and yarn changeovers take longer. A buyer who wants a tight retail price should reduce complexity before asking for a lower quote.
A concrete PO block should read like this: Style: 280gsm woven cotton-poly stadium blanket; Composition: 60/40 cotton-poly or approved 70/30 alternate; Construction: yarn-dyed woven face, merrowed edge or hemmed edge as approved; Finished size: 150x200cm +/-2cm; Fabric gsm: 280gsm finished, conditioned; Stitch: 4-thread overedge, Tex 27-40 polyester thread, edge width 6-8mm, or hemmed fold 15-20mm if selected; Packing: one piece per belly band or insert card, then polybag; Carton qty: 20-25 pcs per carton; Carton marking: style, colour, size, qty, gross/net weight, carton no.; Inspection: AQL 2.5 major, 4.0 minor unless buyer contract says otherwise; Shipment term: FOB Ningbo or FOB Shanghai; Overrun/underrun: +/-5% only with written approval. That level of detail lets the factory quote the same programme instead of interpreting a loose merchandising brief.
For packaging, specify whether the blanket ships folded, rolled, or banded. Fold style affects carton efficiency and crease appearance. Rolled packing looks premium but adds labour and can increase volume. Flat-folded packing is cheaper and stacks better but may need a better insert card or belly band to survive retail handling. If the club shop wants shelf presentation, ask for a first-fold reference photo and approve it before bulk packing.
FOB costing moves with a few predictable choices
In a woven blanket programme, the cost drivers are usually not mysterious. Yarn-dyed colour changes, tighter size tolerance, brushing, decorative edge work, and custom packing move price more than the difference between 60/40 and 70/30 on a small order. If the fabric is plain woven and piece-dyed, colour cost can be lower, but the shade-risk profile changes. If the blanket is yarn-dyed, the loom schedule and yarn handling are more complex, which usually raises unit price but improves stripe or check control.
Brushing is a real cost item. Light brushing can improve hand feel, but it adds processing time and raises pilling risk, which means more QA time and often more rejected lots. A hemmed perimeter generally costs more sewing labour than a simple merrowed edge, but it gives a cleaner look and can reduce edge curl complaints. A tighter size tolerance usually increases cutting waste and inspection time, so a buyer should only pay for it when shelf presentation or stacking requires it. Ask mills to separate these charges line by line in the quote rather than burying them in one unit price.
Packing also moves cost in a measurable way. One blanket per belly band is usually cheaper than a printed insert card plus polybag plus hangtag set. A retail-ready presentation can add several cents to over a dollar per unit depending on finishing complexity and carton packing density. The real question is whether that spend improves sell-through enough to justify it. For club-shop goods, the answer is often yes when the blanket is a gift item or supporter's product, and less often yes when it is a seasonal price fighter.
Freight terms should be quoted cleanly. Use FOB when the buyer controls main carriage and wants a clean ex-factory plus port handover comparison. Use CIF only when the quote explicitly includes ocean freight and insurance, and keep the same Incoterm across supplier comparisons. If the order is being packed for a retail DC with fixed receiving windows, ask for carton dimensions and pallet pattern early; freight volume can matter as much as fabric cost.
What to ask the factory before you place the order
Supplier-side evidence is what turns a quote into a controlled order. Ask for lab dip approval, pre-production sample, yarn or fabric swatches, mill test report, first bulk inspection photos, and packing mock-up. For coloured woven blankets, request a retained shade standard and a batch control card linked to the colour lot. If the blanket uses a decorative edge, ask the factory to photograph the stitch chain under magnification or at least close range before bulk release.
A practical buyer checklist is: confirm finished gsm basis; confirm blend ratio with fibre content statement; approve construction type and edge method; approve size tolerance; lock care method and wash-test route; lock shade approval protocol with Delta E or visual pass/fail; define inspection level; confirm carton count and cube; review lead time against yarn availability; ask for replacement rules for shade, edge, and size failures. That list is the difference between a clean production run and a batch of arguments after the goods are on the water.
For QA, use AQL as a contract tool, not a decoration. A common starting point for textile soft goods is AQL 2.5 for major defects and 4.0 for minor defects, but the buyer may tighten this for premium club retail. Define major defects as edge unravel, size out of tolerance beyond the agreed limit, shade fail, or wash failure; define minor defects as loose threads, isolated stitch irregularity, or cosmetic packing error. If the buyer has a stricter retail standard, write it in the PO and keep the inspection photos linked to that same standard.
The blanket only becomes easy to buy after these details are fixed. Without them, the same phrase can hide several different constructions, and the quote will not be comparable across mills.
Frequently asked
Should 280gsm mean the greige cloth or the finished blanket? For sourcing, use finished and conditioned fabric weight. If a supplier quotes greige gsm, it is not directly comparable to a finished-goods quote because dyeing, brushing, washing, and edge construction change the final mass and hand.
Is 60/40 or 70/30 better for a stadium blanket? Use 60/40 when hand feel and retail presentation matter more. Use 70/30 when size stability, quicker drying, and lower shrink risk matter more. The better choice depends on wash frequency, price target, and whether the programme is retail or promotional.
What is the right edge construction to specify? Pick one primary path: hemmed woven edge or merrowed/overedge edge. If you say merrowed, define thread count, stitch class, and edge width. If you say hemmed, define fold depth, stitch type, and corner finish.
Which wash test should be written into the PO? Use ISO 6330 with the exact wash programme, detergent, load type, and drying condition written out. For example, 5A at 40C with standard detergent, then line dry or tumble dry only if the care label allows it. Add ISO 5077 for dimensional change and ISO 12945-2 if the surface is brushed or napped.
How should shade be approved? Use lab dips or strike-offs against the approved physical standard under D65 and TL84, with the acceptance rule written as visual pass/fail plus a recorded Delta E tolerance if your buyer standard uses one. Do not rely on a vague promise to match the sample.
What inspection level is reasonable? A common starting point is AQL 2.5 major and 4.0 minor for textile soft goods. Tighten it if the retail channel is premium or if edge quality and shade consistency are critical to sell-through.
