The buying decision is not just GSM
A 10gsm difference is not commercially decisive by itself. A 320gsm Raschel can still read lighter than a 310gsm plush if the pile is open and the ground shows through. The real drivers are yarn fineness, pile density, shearing depth, heat-setting, and how the fabric behaves after packing and handling.
For sourcing, the first task is to define the construction correctly. Raschel is a warp-knit family, usually with a visible ground structure that can be brushed or sheared after knitting. PV plush is a commercial label, not a single technical construction. In practice it may refer to a dense brushed plush, a compact pile fabric, or a PV fleece/plush style face. If the PO only says “PV plush,” the mill has room to substitute a look-alike structure. The spec must name the yarn system, face construction, pile target, and finishing route.
A buyer should compare these throws on four questions: does the face stay even under studio lighting, does it shed lint in handling, does it recover after compression, and does it hold shade and surface after the first laundering cycle? That is the real shortlist. For broader throw sourcing context, see promotional stadium throw sourcing and fleece weight throw blanket program.
Spec table: construction first, positioning second
Use this as a procurement screen. The ranges below are commercial targets, not universal constants. Final numbers should be locked against the sealed sample and the approved production lot.
| Spec item | 320gsm Raschel polyester | 310gsm PV plush | Buyer note |
|---|---|---|---|
| Base structure | Warp-knit Raschel ground, then brushed or lightly sheared | Dense plush or pile face, usually with tighter surface presentation | Raschel is more forgiving on texture variation; PV plush reads cleaner on camera |
| Typical yarn | 100% polyester DTY, commonly 150D/96F to 250D/144F | 100% polyester pile yarn, often 75D/72F to 150D/144F | Finer yarn improves visual smoothness but can reduce crush recovery if packed hard |
| Finished GSM | 320gsm target, common tolerance +/- 5% | 310gsm target, common tolerance +/- 5% | Weight alone does not predict pile density or face cleanliness |
| Pile height | About 2.0-4.0 mm after finishing | About 1.5-3.0 mm after finishing | Longer pile hides knit noise but increases snag and crush risk |
| Size control | Common blanket sizes 130x170 cm or 150x200 cm, cut tolerance usually +/- 2 cm | Same size window, but pack-face appearance is more sensitive to fold memory | State lay-flat measurement method in the tech pack |
| Wash shrinkage | Target no more than 3% after 1 domestic cycle | Target no more than 3% after 1 domestic cycle | Use ISO 6330 or a buyer-agreed laundering route |
| Pilling | ISO 12945-2 grade 3.5 to 4 after agreed cycles | ISO 12945-2 grade 3.5 to 4 after agreed cycles | For retail throws, grade 3 is usually too weak unless the price point is very low |
| Lint release | Should be controlled before pack-out and remain stable after carton compression | Usually cleaner at first touch, but more sensitive to over-brushing | Write the lint method into the PO; do not leave it as a vague “no shedding” claim |
| Crush recovery | Moderate to good if heat-set correctly | Good only if pile is not over-flattened during packing | PV plush is less forgiving of vacuum packing and tight bundling |
| Commercial fit | Value-led retail, larger colour runs, price-sensitive home shopping slots | Cleaner premium look, softer visual hand, tighter merchandising story | Choose based on channel economics, not fabric prestige |
A 10gsm difference should not be oversold. A lower-GSM plush can still look fuller than a higher-GSM Raschel if the pile is denser and the finish is tighter. Buyers should compare pile density, yarn fineness, heat-set stability, and post-pack appearance, not just the scale reading.
Pile formation, shearing, and heat-setting need separate controls
Raschel is a warp-knit construction. The fabric can be engineered with loop formation, then brushed or sheared to the final face. PV plush needs separate definition because the label is used loosely across mills. In buyer language, that label should be narrowed to the exact face type: brushed plush, pile plush, or PV fleece/plush. Otherwise the supplier can change the cloth under the same commercial name.
Shearing is a finishing step, not a fabric type. It can be used on either construction to reduce surface height variation and sharpen the visual face. A practical buyer spec is to name the finished pile height and allowable variation against the sealed sample. For a dense plush face, a tolerance around +/- 0.2 to 0.4 mm on pile height is a reasonable control point if the mill has stable blade maintenance and a controlled line speed. On a more open Raschel surface, the acceptable variation may need to be wider because the ground structure shows sooner.
Heat-setting should be written as a process requirement, not a broad range with no context. A general polyester setting window of about 160 to 190 C is common, but the correct set point depends on denier, dwell time, overfeed, and whether the cloth is brushed before or after dyeing. For a finer yarn, the lower end of that range is often enough; for denser fabric or a heavy finish stack, the mill may need a higher set point with shorter dwell. The acceptance criterion should be residual shrinkage, not just machine temperature. If recycled polyester is involved, validate against the first bulk lot, because recycled feedstock can widen process spread.
Common failure modes are predictable. Uneven blade wear creates striping. Over-shearing exposes the ground and makes the fabric read thin. Under-shearing leaves a cloudy, dusty face that traps lint. Excess heat flattens the pile and reduces recovery. Under-setting leads to pack lines, roll-to-roll drift, and shade banding. For approval, ask for top, middle, and tail samples from the same lot and compare them under the same light source.
Lint control should be measurable
“Low lint” is not a spec unless the method is named. For an internal QC protocol, a buyer can use a simple handling screen: fold the sample five times, shake it over black card for 10 seconds, then rub it 10 times with a standard white cloth under consistent pressure and inspect the residue against the approved reference. Record the sample area, cloth type, lighting, and pass/fail result. That is a practical factory check, but it is an internal method, not a recognised lab standard.
Do not imply equivalence between an in-house shake/rub test and a formal laboratory test. If the programme needs a lab basis, specify the method actually being used by the buyer or factory, then anchor the acceptance to that report. For home shopping throws, a practical PO line is: no visible fibre transfer at normal viewing distance on black card after handling, and no loose-fibre accumulation that leaves visible residue on the hand after three handling cycles. That is demanding, but it is realistic for camera-led sales.
Upstream controls matter more than slogans. The main levers are yarn twist, fibre quality, brush intensity, shearing depth, vacuum de-linting before pack, and clean pack materials. Rough polybags, dusty carton interiors, and high-friction compression wraps will abrade the face and create complaint risk even when the fabric is otherwise sound.
Bulk approval needs a complete checklist
Bulk approval usually fails because the sample is judged as a single piece, while production is judged as a spread. The approval pack should include the sealed standard, shade band limits, pile-height target, GSM tolerance, pack method, and label placement artwork. It should also name the inspection method and defect classification before production starts.
A workable inspection basis is AQL 2.5 for major defects and AQL 4.0 for minor defects, unless the customer standard is stricter. Treat as major defects: holes, bare-pile patches, severe shade banding, broken seams, size outside tolerance, wrong label, contamination on the face, and pile collapse that does not recover after standard shaking. Treat as minor defects: slight seam waviness, small packaging marks, or tiny reverse-side blemishes that do not affect saleability.
Define the inspection area in the PO. A common method is full-face inspection of each sampled throw under standard light at about 1 m viewing distance, followed by spot-checks of the reverse, edges, and label position. A rejectable shade issue is one that is visible across the panel under the agreed light source when compared with the master standard. A rejectable pile defect is a flat, bald, streaked, or matted zone larger than the agreed maximum size; for visual retail, that is often around 2 to 3 cm, though some channels will demand tighter control.
The buyer-facing approval sheet should include this minimum checklist: finished GSM, size, pile height, shrinkage after the agreed wash cycle, pilling grade, lint control result, shade tolerance, seam quality, label accuracy, carton pack count, and pack compression condition. For a first production run, require a pre-shipment sample or a photo approval set before the bulk ships.
Commercial fit depends on channel economics
Choose 320gsm Raschel when the programme needs better cost stability, a more forgiving surface, and colour runs that can absorb some visual variation. It is usually the lower-risk option for value-led home shopping drops, private label seasonal programmes, and larger order quantities where roll-to-roll consistency matters more than a perfectly smooth face.
Choose 310gsm PV plush when the brand wants a cleaner, denser visual hand and the channel will pay for tighter finishing control. PV plush is usually stronger for studio presentation, darker fashion shades, and gift-style merchandising. The trade-off is lower tolerance for pile crush, over-compression, and finish drift.
A simple rule works well: if the buyer prioritises price, throughput, and a textured look that hides process noise, specify Raschel. If the buyer prioritises a smoother surface, stronger camera read, and a more elevated retail impression, specify PV plush. If the programme will be vacuum-packed or heavily handled in distribution, Raschel is usually the safer build; if it will sit in display packaging with lighter handling, PV plush can justify the extra control.
Commercial risk is usually not the fabric itself. It is colour-dye consistency, late shade approval, and pack-out drift. For a run of dark colours, set a shade band limit before bulk, lock the master under D65 and TL84 if needed, and require the first bulk roll to match the sealed sample on both face and reverse. On programmes with multiple colourways, insist on a lab dip or strike-off for each colour and freeze the recipe before yardage starts.
Write the PO like a manufacturing spec
The fastest way to avoid disputes is to turn the approved sample into a production spec. For either construction, the PO should state the fibre composition, yarn denier and filament count, base structure, face finish, GSM tolerance, pile height target, dimensional tolerance, wash shrinkage target, pilling target, lint method, shade band limits, packaging format, carton count, and inspection basis.
A useful buyer checklist is: 100% polyester or declared blend, exact yarn spec, finished GSM, finished pile height, size, ISO 6330 shrinkage target, ISO 12945-2 pilling target, lint screening method, AQL level, shade approval standard, and pack/compression requirement. If the throw will be sold through a home shopping channel, add a camera approval sample and a bulk photo sign-off before shipment.
For larger orders, also define MOQ sensitivity and lead time dependence. Surface-finishing programmes usually move when yarn colour is stable, but they slip when the buyer changes shade late, adds extra packaging, or changes the pack ratio after lab approval. The normal control point is not the mill floor; it is the buyer’s approval calendar. Locking the shade, finish, and pack spec early is what keeps the programme moving.
Frequently asked
Is Raschel or PV plush better for home shopping throws? Neither is universally better. Raschel is usually more forgiving on cost, texture variation, and compressed packing. PV plush usually gives a cleaner, denser visual face and a better studio read. Choose based on channel price point, handling intensity, and how strict the buyer is on surface appearance.
Does 320gsm automatically mean a better throw than 310gsm? No. GSM is only one input. Yarn fineness, pile density, finish, and compression recovery matter more to the final look. A 310gsm plush can look fuller than a 320gsm Raschel if the construction is tighter and the pile is controlled.
How should lint be specified? Use a named method. If you use an internal shake/rub check, call it internal QC and define the steps. If you want laboratory testing, specify the exact test standard or buyer method. Do not write “no shedding” without a test basis.
What is a realistic shrinkage target? For polyester throws, a common commercial target is no more than 3% after one domestic wash cycle, measured to ISO 6330 or an agreed buyer laundering route. The acceptable limit depends on the channel and the pack format.
What usually causes bulk approval failures? Late shade drift, pile crush, visible lint, label errors, and sample-to-bulk variation. The weak point is often process control and packing, not the cloth weight itself.
