Start with the use case, not the colour name
A solution-dyed 220gsm polyester microfleece travel blanket is usually bought for loose onboard service items in airline cabins, rail and coach amenity programmes, hospitality packs, or premium promotional distribution. At 220gsm fabric weight, it sits in a useful middle zone: lighter and more cube-efficient than 260-300gsm fleece, but less flimsy than 140-185gsm giveaway constructions.
Do not spec only gsm. Write the construction as a full line: 100% polyester microfleece, circular knit or warp-knit base as applicable, solution dyed, brushed on one face, anti-pilling finish, pile height about 1.0-1.6mm after finishing, finished width to suit cut plan, edge finish as approved. If the mill cannot confirm knit type, yarn format, approximate filament denier range, brushing side, and finishing route, the quote is not yet comparable.
Separate fabric GSM from finished blanket unit weight. A blanket can meet 220gsm on the roll and still miss the expected finished mass after cutting loss, edge sewing, moisture regain, or size shortfall. State both: for example, fabric 220gsm ±5% and finished blanket mass 470g ±5% for a buyer-approved size, measured after conditioning to ISO 139 atmosphere. Also state finished size tolerance, for example 130 x 170cm ±2% or 150 x 200cm ±2% depending on programme.
Write the duty cycle into the brief. A one-off welcome item can tolerate wider variation than a multi-season transport programme. If the blanket will be folded into a belly band, pouch, or polybag, define finished size, folded pack size, and carton quantity early because these drive fabric width, cut plan, edge bulk, and freight cost. Useful adjacent references are travel airline blanket weight packing and specifying 180gsm microfleece travel blankets with nylon carry pouches.
RFQ language that prevents shade drift
Specify the fibre route clearly: 100% polyester, solution dyed or dope dyed, brushed microfleece face, nominal 220gsm fabric weight, and an explicit finished blanket mass tolerance. Ask the mill to state whether the body yarn, sewing thread, binding, label, and packaging trims are colour-matched components or separate dyelots. On travel blankets, mismatch often shows first at the thread or edge tape, not the fleece body.
Make the colour spec enforceable on pile fabric. If you use instrumental control, define the method in the RFQ: specimens conditioned to ISO 139, pile laid in the approved direction, measured with a bench spectrophotometer under D65/10°, SCI and buyer-agreed SCE check if required, aperture typically 8mm or larger, at least 5 readings across face fabric, average reported with max single-point deviation. On brushed fleece, state whether visual approval against the signed master under a standard light box overrides instrument readings where pile orientation creates acceptable numeric spread.
A realistic colour tolerance on microfleece is often CIEDE2000 average ≤1.2 to 1.5 with no single reading above an agreed ceiling such as 1.8, provided nap direction, instrument geometry, and conditioning are fixed. A blanket programme that demands ΔE00 ≤1.0 can be done on some shades, but it is not a sensible default unless the buyer controls pile presentation, master standard age, and visual override rules.
Put measurable acceptance items into the RFQ: shade tolerance against the signed and measured master, pilling after laundering, seam strength, dimensional change after laundering, lint transfer, edge curl, and carton markings. Ask for references to ISO 105-B02, ISO 105-C06, ISO 105-X12, ISO 12945-2, and ISO 6330, but do not accept a generic “passes” statement without the exact programme and grade result. If logos are involved, align the body, label, print, and edge trim colour routes before sampling. Related sourcing logic: solution-dyed 260gsm polyester fleece throws MOQ trade-offs and custom blanket decoration methods.
Performance targets buyers can actually quote
Build the technical sheet around measurable pass/fail criteria. For light fastness, state one reporting system clearly. A workable transport-facing target is ISO 105-B02 minimum Blue Wool 4 for standard shades, with some buyers asking for Blue Wool 5 on window-exposed or premium programmes. Do not mix Blue Wool wording with grey-scale change-of-colour wording in the same requirement.
For wash fastness, name the exact route. Example wording: ISO 105-C06, test A1S, change in colour minimum grade 4 and staining minimum grade 3-4 to adjacent multifibre after one agreed domestic-laundry equivalent cycle. If your service route uses home laundering, align this with ISO 6330 and state the wash programme, detergent type, ballast if required by the lab, drying route, and number of cycles. Without that detail, lab reports are not comparable.
For rubbing fastness, a practical target is ISO 105-X12 dry grade 4 minimum, wet grade 3-4 minimum. For pilling, require ISO 12945-2 on fabric taken from the finished blanket, and tie it to laundering: for example minimum grade 3-4 after 5 domestic wash-and-dry cycles by the agreed ISO 6330 route, then tested for 2,000-5,000 rubs as specified. Fresh-fabric pilling results alone are weak predictors of service performance on travel fleece.
If abrasion is relevant, cite the exact method variant and endpoint. Example: ISO 12947 Martindale, agreed load and specimen preparation, no hole, no base exposure, and no unacceptable pile loss before 12,000-15,000 cycles. For seams, add a construction target using a relevant tensile or seam-strength method if needed, especially where blankets are repeatedly folded into pouches or secured with straps. Buyers working across outdoor or mixed-use packs may also review adjacent guidance such as ASTM D5034 seam strength targets.
For dimensional stability and appearance after care, state ISO 6330 home laundering route, drying method, cycle count, and acceptance: typically length and width change within ±3%, no severe seam grin, no pronounced torque, and no edge curl above a buyer-agreed limit such as 5-8mm lift over a 1m laid-flat section. If care labeling will be buyer-facing, align symbols to ISO 3758 care labeling.
Why solution dyeing helps, and where it does not
With solution dyeing, pigment is incorporated into the polymer before filament formation rather than applied only after fibre production. In practice, this often improves shade stability to light and repeated washing, and reduces lot-to-lot drift on core colours where the supply chain is well controlled.
The trade-off is commercial and technical. Solution-dyed programmes usually need firmer colour commitment, higher opening quantities, and fewer late changes. Common stock shades such as navy, charcoal, black, or beige are easier to support than brand-specific warm greys, muted greens, or low-chroma pastels. Lighter and warmer shades can still need their own test data; do not assume the body colour will inherit the best result from a dark stock programme.
Do not overclaim abrasion or wash performance just because the yarn is solution dyed. Actual results still depend on fibre fineness, knit density, brushing intensity, anti-pilling chemistry, and whether the thread, binding, labels, and print system are equally stable. Ask for test reports on the approved colour and approved package, not only on a generic development shade.
Ask for evidence that includes face fabric, reverse, edge finish, sewing thread, and any label or decoration after washing and abrasion. On brushed travel blankets, a colour-stable body with mismatched overlock thread is still a reject in use. Adjacent reading: solution-dyed 220gsm polyester fleece blankets and ISO 105-B02.
Edge construction changes performance, bulk, and failure risk
Buyers often write “finished edges” as if that were one variable. It is not. Overlocked edges are usually the lowest-bulk and lowest-cost route for travel blankets, with decent flexibility and compact folding, but thread mismatch and edge ripple are more visible. Turned-and-hemmed edges look cleaner on some retail programmes and can reduce loose edge exposure, but they add bulk, reduce stretch at the perimeter, and may create corner torque on lightweight fleece. Bound edges give a more defined perimeter and can improve perceived quality, but they add pack thickness, create another colour-matching component, and can fail by seam grin or puckering if tension is not balanced.
If curl control matters, ask the supplier to trial the edge finish on the actual knit and brushing route. A fabric that lies flat with overlock may curl after binding because the tape tension is too high, while a hemmed edge can look square in inspection but feel noticeably thicker in a pouch-packed airline programme.
Put the edge into the spec with measurable values: stitch type, seam allowance, thread size, stitch density, and binding width where relevant. Typical starting points are overlock width 4-5mm, 10-12 stitches per inch or about 3.9-4.7 stitches/cm, and polyester thread around Tex 24-30 for light travel fleece. Bound-edge blankets may need a wider seam build and tighter inspection of corner turn quality.
If colour continuity matters, require the edge component to be approved with the body under the same lighting. A body made from solution-dyed fleece with piece-dyed binding can pass fabric tests and still fail visual approval. For practical construction comparisons, see whipped-stitch edge specification and coverstitch edge SPI guidance.
Compliance is a gating item for transport programmes
For airline, rail, and coach programmes, compliance should be split by actual use. Loose onboard service blankets are not automatically subject to the same fire-test pathway as installed aircraft interior components. If the blanket is a removable service item, confirm the operator requirement in writing instead of assuming FAR 25.853 by default. If the product is an installed or semi-installed interior component, a different fire qualification route may apply and has to be specified by the customer or certification team.
For rail, ask whether the buyer is working to EN 45545 and which hazard level or component logic applies, or whether the operator uses its own approved-material list. For coach, bus, or hospitality transport channels, operator-specific requirements are common. The right RFQ wording is not “meets transport rules”; it is a matrix listing standard, clause or route if relevant, material scope, finished-product scope, and responsible approving party.
Chemical compliance should also be scoped by market and age grade. A sensible starting screen may include REACH Annex XVII restricted substances, azo dye screening where relevant, and destination-specific review such as CPSIA tracking and substrate review for children’s routes or Prop 65 screening where California exposure language may be triggered. Blanket buyers should ask whether the report covers fabric only or the full article including thread, labels, print, binding, polybag ink, and accessories.
The RFQ should ask for a compliance matrix with standard, exact test method, specimen count, report number, report date, lab identity, and component coverage. A common late-stage failure is discovering that the lab tested only the fleece panel while the sewn label, edge tape, or print binder was outside scope. Related references include FAR 25.853 burn testing for airline blankets and DIN EN 14533 burn-behaviour review.
Sampling should test more than handfeel
Do not approve on softness alone. A proper sample set should include lab dips or shade bands, pre-production yardage, a sewn blanket with final edge construction, and the final packaging format. Check pile recovery after compression, edge flatness, stitch consistency, folded pack dimensions, and appearance after at least one agreed wash route if the programme is not strictly single-use.
Replace subjective lint checks with a written protocol. One workable buyer method is: condition both blanket and transfer cloth to ISO 139; use a standard black cotton test cloth or other buyer-approved reference substrate; mount specimen flat; rub with a defined head or sled at an agreed pressure such as about 9N, 100mm stroke length, 20 cycles; then assess transfer under a D65 light box or 1000 ± 200 lux neutral viewing booth against a photo standard. Pass/fail should be tied to a retained visual standard or a maximum rating on a buyer-defined lint scale, not “obvious haze”.
For compression recovery, define the method. Example: measure blanket thickness under a buyer-agreed low pressure, fold to production pack format, compress under a stated load for a stated time, release, and require at least 85-90% thickness recovery within 5-10 minutes. The exact threshold depends on whether the blanket is packed once for retail or repeatedly repacked in service.
Static behaviour also needs a reproducible check. If there is no formal customer method, write an internal approval route with atmosphere, substrate, and endpoint: for example conditioned at 20-23°C and 45-55% RH, unpacked from final polybag, shaken and laid over a standard chair or fabric panel, then assessed after 30 seconds for persistent cling beyond the approved photo standard. Use one retained internal SOP and keep it stable across reorders rather than improvising at each approval.
Set an inspection plan that matches the programme risk. A common starting point is AQL 2.5 major / 4.0 minor, with tighter major-defect limits for premium cabin programmes. Record size, finished weight, colour delta, seam build, thread colour, label position, fold dimensions, and pack count on the sample approval memo. If the buyer has no internal visual standard, create one before bulk approval. Related checklists: AQL 2.5 inspection checklist and blanket quality control inspection.
PO controls that keep the bulk run honest
The purchase order should read like a control document, not a sales summary. Include fibre content, knit type if known, nominal fabric gsm, finished blanket size, finished blanket target mass, tolerance bands, brushing side, anti-pilling finish, approved colour standard, edge construction, thread spec, label type, fold format, inner pack, carton quantity, carton markings, Incoterm, and ship-ready window.
Add retained-sample and change-control language. Practical wording is: bulk production to match buyer-approved gold-seal sample retained by both buyer and mill; no change to yarn source, knitting mill, brushing route, anti-pilling finish, edge construction, thread shade, label vendor, or packaging material without written buyer approval. This matters more on repeat transport programmes than another one-point argument about gsm.
Require batch traceability. At minimum, each carton should be traceable to production lot, sewing line or date code, colour lot, and PO number. Carton marking usually needs item code, colour, size, quantity, gross/net weight, carton number sequence, country of origin, and any customer routing marks. For reorders, ask the mill to retain fabric lot records, colour measurement data, and approval references for a sensible period agreed by contract.
State exact tolerances. Example line items: fabric 220gsm ±5%, finished size ±2%, finished blanket mass ±5% after conditioning to ISO 139, folded size ±5mm where shelf pack matters, label placement ±10mm, and edge construction as approved. Without a finished-mass tolerance, a supplier can technically hit gsm while delivering a blanket that feels lighter because size or cut yield has drifted.
Set an inspection standard and a change-notification rule on the PO. Example: final inspection to AQL 2.5 major / 4.0 minor unless otherwise agreed; any material, colour, trim, packaging, or factory-subprocess change to be notified before bulk start. Also specify whether duplicate tested bulk swatches, pre-shipment photos, or sealed TOP samples are required before release. Related process references are custom blanket lead times shipping and EXW vs FOB Ningbo cost items.
Operating numbers buyers usually need before approving
Typical travel blanket sizes in this weight class are roughly 120 x 150cm, 130 x 170cm, and 150 x 180cm. A 130 x 170cm blanket at 220gsm fabric weight often lands around 430-500g finished depending on pile yield, edge finish, and trim weight. A 150 x 180cm version will naturally pack much heavier and may move out of the preferred amenity-carton range.
Folded pack dimensions vary with fleece loft and edge build, but a 220gsm microfleece travel blanket commonly folds to around 30 x 25 x 6cm to 35 x 28 x 7cm in a simple belly-band format. Polybag or pouch packing can tighten cube slightly, while bound edges and inserts add bulk. Always approve the real folded pack, not a theoretical number.
Carton planning should be done against weight and cube together. As a broad working range, you may see 12-24 pcs per carton for this category, with carton sizes often around 50-60cm x 40-45cm x 35-45cm and gross weights around 8-15kg depending on unit size and compression level. The right answer depends on destination handling limits, pallet pattern, and whether the consignee prioritises easier manual handling or lower freight per piece.
MOQ and lead time usually differ by colour route. Stock solution-dyed shades may be possible at lower starting quantities and shorter lead times, while custom solution-dyed shades generally need higher minimums and longer yarn planning. As a rough market pattern, a buyer may find stock shades more feasible from low-thousands upward, while custom shades often need a stronger volume commitment and can add a few weeks to the calendar. Confirm the actual dye-route and yarn availability before quoting a launch date.
If the blanket is part of a broader transport or amenity range, compare the 220gsm programme against lighter options such as 185gsm polyester airline blankets or recycled alternatives such as 210gsm rPET microfleece airline blankets.
A practical buyer spec block
A workable starting specification might read: 100% polyester solution-dyed microfleece travel blanket; brushed one face; anti-pilling finish; nominal fabric weight 220gsm ±5%; finished size 130 x 170cm ±2%; finished blanket mass 470g ±5% after ISO 139 conditioning; overlocked edge 4-5mm width, 10-12 SPI, polyester thread Tex 24-30 colour matched to approved standard; folded pack 32 x 26 x 6cm ±5mm; 16 pcs/carton; AQL 2.5 major / 4.0 minor.
Performance block: ISO 105-B02 minimum Blue Wool 4; ISO 105-C06 A1S colour change minimum 4 and staining minimum 3-4; ISO 105-X12 dry 4 minimum, wet 3-4 minimum; ISO 6330 agreed wash route with dimensional change within ±3%; ISO 12945-2 pilling minimum 3-4 after agreed laundering route; lint transfer by buyer-approved internal method against retained photo standard.
Control block: production to match signed gold-seal sample; no fibre, yarn, mill, finish, trim, or packaging change without written approval; carton and lot traceability mandatory; compliance matrix to cover finished article and all critical components. This level of detail is not over-specification. It is what makes the second and third reorder look like the first shipment instead of a close substitute.
Frequently asked
Is 220gsm a good weight for travel blankets? For many airline, rail, coach, and amenity uses, yes. Around 220gsm fabric weight is a practical middle point between very light giveaway fleece and bulkier 260-300gsm throws. The right choice still depends on finished size, folded pack target, and whether the blanket is single-distribution or expected to survive repeated washing.
How should buyers specify colour on brushed microfleece? Do not rely on a colour name alone. Use a signed physical master, define ISO 139 conditioning, nap direction, instrument settings, viewing light, number of readings, and whether visual approval can override instrument results on pile fabric. On brushed fleece, a realistic average tolerance is often around CIEDE2000 1.2-1.5 rather than an unconditional 1.0.
Does solution dyeing guarantee better performance? Not automatically. Solution dyeing often improves light and wash stability, especially on core shades, but the result still depends on fibre, knit density, brushing, anti-pilling finish, and colour. Approved shades should still have their own test data, particularly lighter, warmer, or brand-critical colours.
What test methods matter most for a travel blanket programme? Typical priority methods are ISO 105-B02 for light fastness, ISO 105-C06 with the exact variant stated for wash fastness, ISO 105-X12 for rubbing fastness, ISO 6330 for the laundering route, and ISO 12945-2 for pilling after the agreed wash route. If abrasion matters, specify the exact ISO 12947 setup and failure endpoint as well.
Should travel blankets be tested to FAR 25.853 by default? No. Loose onboard service blankets are not automatically treated the same as installed aircraft interior components. The correct route depends on the operator and use case. For rail programmes, buyers should also ask whether EN 45545 or an operator-specific requirement applies.
What edge finish is usually best for a 220gsm microfleece travel blanket? Overlocked edges are common because they keep pack thickness and cost down. Hemmed edges can look cleaner but add bulk, while bound edges can improve perceived finish but add another colour-matching component and more seam-failure risk if tension is wrong. The best choice depends on pack format, visual expectation, and service life.
What PO controls reduce reorder risk? Retain a gold-seal sample, prohibit yarn or finish changes without written approval, require batch traceability, define AQL, lock carton markings, and state all tolerances for size, finished mass, fold size, and edge construction. Without these controls, repeat orders often drift even if the nominal gsm stays the same.
