Custom Woven Patch Spec Sheet: Line Items Buyers Must Lock

1. Patch Construction: When Woven Is the Right Build

A woven patch is not just a “fabric badge.” It is a polyester yarn construction made on a loom, then cut, bordered and backed according to the order spec. It is usually the best choice when the artwork contains small text, thin lines, tight curves, badges, retail labels, club emblems, event merchandise or uniform logos that would close up in embroidery.

For a purchase order, specify “woven polyester patch” and define the end use. Standard woven patches use 75D to 150D polyester yarn. Fine-detail patches normally use 75D or 100D yarn at higher weave density; heavier, simpler patches may use 150D yarn. Finished patch thickness before backing is typically 0.6 to 1.2 mm. With merrow border and backing, total thickness often reaches 1.5 to 2.8 mm depending on edge and attachment method.

Woven is not always the right product. If the buyer wants a raised tactical or traditional military texture, embroidery is more suitable. If the patch must be waterproof, flexible and molded in relief, PVC is stronger, although it is thicker at roughly 2.0 to 4.0 mm and requires tooling. If the artwork contains photos or smooth gradients, sublimation or printed fabric will reproduce tone transitions more accurately than woven yarn.

Patch build	Best use	Technical limitation	Typical FOB China range at 1,000 pcs
Woven polyester	Small text, fine logos, retail labels, staff badges	Limited raised texture; gradients are simulated with yarns	USD 0.30 to 0.85 per pc
Embroidered	Bold logos, uniform badges, heritage or textured look	Letters under 5 mm and thin outlines may close up	USD 0.38 to 1.15 per pc
PVC molded	Outdoor, waterproof, tactical, luggage and morale patches	Mold charge; thicker profile; not ideal for fine shading	USD 0.60 to 1.90 per pc plus tooling
Printed fabric	Photos, gradients, low-cost event patches	Lower tactile value; print abrasion risk	USD 0.18 to 0.65 per pc

2. Finished Size, Shape and Dimensional Tolerance

State the finished size in millimeters, measured at the widest points after border and backing are applied. Do not give only the artwork size. A 70 mm woven circle with a 3 mm merrow border is ordered as a 70 mm finished diameter, not a 64 mm artwork plus border unless that is explicitly stated.

For circles, specify finished diameter. For rectangles and name strips, specify finished width by height. For shields, mascots and irregular cuts, provide maximum width, maximum height and a 1:1 vector outline in AI, EPS, SVG or PDF. Raster images can guide appearance, but they are not reliable for cut-line control.

A practical production tolerance is ±1.0 mm for patches under 80 mm and ±1.5 mm for patches from 80 to 150 mm. Long narrow strips, such as 100 x 18 mm name tapes, may bow or shrink during heat pressing; use ±1.5 mm on length and ±1.0 mm on height unless the receiving panel requires a tighter fit. If the patch must sit inside a recessed box insert, cap panel or bag window, specify a negative-fit tolerance such as -0.5 mm / +0 mm and confirm the receiving area dimensions.

For laser-cut irregular patches, avoid inside curves below a 2.0 mm radius and protrusions below 1.5 mm width. These features can fuzz, scorch or bend after washing. Sharp hair strands, serif tips and star points should be simplified in artwork before sampling; they cannot be corrected cleanly after weaving.

3. Yarn Denier, Text Legibility and Color Control

Detail is controlled by yarn denier, weave density, stroke width and color transitions. A safe minimum letter height is 4.0 mm for uppercase block letters, 5.0 mm for lowercase sans serif and 6.0 mm or more for serif fonts. On the artwork, thin strokes should be at least 0.35 mm; for dark grounds, bulk production is safer at 0.50 mm because contrast loss and yarn spread can close fine spaces.

Most commercial woven patches run well with 2 to 8 yarn colors. Nine to twelve colors are possible on suitable looms, but cost rises because setup is slower and the reverse side becomes bulkier. More color changes also increase the chance that small areas look muddy. If a shadow or tiny highlight is not essential, merge it into the nearest yarn color.

Use Pantone Solid Coated references for communication, but understand that dyed polyester yarn is not ink. A normal commercial color tolerance is about Delta E 2.0 to 4.0 against the approved yarn card or physical sample. Fluorescent, metallic and very deep saturated colors may have fewer yarn options and wider visual variation. For brand marks, write “critical color: approve by physical yarn card or sample.” For non-critical background colors, write “closest available yarn acceptable.”

For gradient effects, woven construction uses dithering or alternating yarns. It can suggest shading on a 90 mm badge, but it will not reproduce continuous-tone artwork like sublimation. If the artwork has a face, landscape, smoke effect or photograph, request a printed-fabric comparison before approving woven production.

4. Border Specification and Edge Durability

The border controls durability as much as appearance. Merrowed overlock is the standard for circles, ovals, rectangles, shields and simple curves. It is usually 2.5 to 4.0 mm wide and raises the edge to about 1.5 to 2.5 mm after backing. It protects yarn ends well during washing and handling, but it cannot follow tight internal corners or highly irregular silhouettes.

Laser-cut and heat-cut edges are better for custom outlines. They follow mascots, letters and asymmetric logos more closely, but the cut edge is flatter and more exposed. For retail patches, backpack patches and removable hook-backed patches, add a 1.0 to 1.5 mm woven outline inside the cut line. That outline improves shape definition and hides minor edge variation.

If the order uses no visible border, the spec must be tighter. Low-density weave, dark yarn on light backing, or frequent handling can make edge fuzz obvious. For children’s products, outdoor patches and workwear, a protected edge is safer than a borderless fashion look.

Border spec	Use it when	Avoid it when	Typical cost impact
Merrowed border, 2.5 to 4.0 mm	Simple shapes, uniform badges, high wash durability	Complex silhouettes, narrow corners, tiny patches	Included or +USD 0.03 to 0.08 per pc
Laser-cut edge	Detailed logo outline, mascot shapes, thin labels	Heavy abrasion without inner outline	＋USD 0.02 to 0.06 per pc
Heat-cut edge with stitched outline	Custom shape needing sharper visual edge	Patches under 30 mm where stitching crowds artwork	＋USD 0.04 to 0.12 per pc
Borderless cut edge	Fashion labels and minimalist retail patches	Outdoor use, children’s items, rough handling	Little saving; higher cosmetic reject risk

5. Backing, Adhesion and Application Parameters

Backing must be specified by material and application method. “Iron-on” is too vague because hot-melt films have different melt points, wash resistance and fabric compatibility. For general cotton or cotton-poly garments, a common hot-melt spec is 150 to 165°C platen temperature, 0.3 to 0.5 MPa pressure and 12 to 18 seconds dwell time, followed by a peel check after cooling for at least 30 seconds.

Heat seal should be tested on the actual fabric. It can fail on DWR-coated nylon, silicone-treated fabric, rough canvas, elastic knits, fleece, low-melting synthetics and heavily textured workwear. For caps, tactical gear, backpacks and uniforms, sewing remains the most reliable attachment. A practical hybrid spec is iron-on backing for positioning plus perimeter sewing by the garment factory.

Hook backing requires its own details: hook color, hook grade, whether the loop mating piece is included, and the edge allowance. Common hook thickness is 1.5 to 2.0 mm. A woven patch with hook backing can finish at 2.5 to 3.5 mm total thickness. For morale patches, specify full-area hook coverage set back 1.5 to 2.0 mm from the edge so the hook does not show or scratch the border.

• No backing: thinnest build; best when the patch will be sewn into garments, caps or labels.
• Iron-on hot-melt backing: convenient for retail and small runs; must be tested on the final fabric.
• Sew-on backing with paper or nonwoven stabilizer: stable, durable and suitable for uniforms.
• Hook backing: best for tactical gear, bags, caps and removable ID patches; confirm loop side if needed.
• Pressure-sensitive adhesive: useful for temporary placement or packaging; not a permanent textile attachment.
• Loop backing: used when the patch itself must receive a hook-backed item.

6. MOQ, Sampling, Lead Time and FOB Price Tiers

For woven patches, setup cost comes from loom programming, artwork conversion, yarn preparation, cutting and border setup. There is usually no metal mold unless the order includes a special fixture or combined PVC part. A workable MOQ is 100 pcs per design, but the unit price improves significantly at 300, 500 and 1,000 pcs because setup time is spread over more pieces.

Quote by design, not only by total order quantity. Twenty designs at 300 pcs each is not the same as one design at 6,000 pcs because each design needs individual setup, sample approval, production control and packing separation. At ZheCraft, normal quotation tiers are 100, 300, 500, 1,000, 3,000 and 5,000 pcs per design.

Order quantity per design	Typical FOB range for 75 mm woven patch, up to 6 colors, merrow border	Typical lead time after approval
100 pcs	USD 0.85 to 1.60 per pc	Sample 5 to 8 days; bulk 7 to 12 days
300 pcs	USD 0.55 to 1.15 per pc	Sample 5 to 8 days; bulk 9 to 15 days
500 pcs	USD 0.45 to 0.95 per pc	Sample 5 to 8 days; bulk 10 to 16 days
1,000 pcs	USD 0.32 to 0.75 per pc	Sample 5 to 8 days; bulk 12 to 18 days
3,000 pcs	USD 0.25 to 0.62 per pc	Sample 5 to 8 days; bulk 15 to 24 days
5,000 pcs	USD 0.22 to 0.55 per pc	Sample 5 to 8 days; bulk 18 to 28 days

Add-ons change price materially. Hook backing plus loop side can add USD 0.12 to 0.35 per pc depending on size. Individual OPP bags, barcode labels or backing cards can add USD 0.03 to 0.18 per pc. Very small patches are not always cheap because programming, trimming, inspection and packing time remain almost the same.

7. Inspection Plan, AQL and Defect Definitions

Quality control should be defined before production. For B2B shipments, a common inspection plan is ISO 2859-1 general inspection level II, with AQL 2.5 for major defects and AQL 4.0 for minor defects. For orders under 500 pcs, 100% visual inspection is often more practical than statistical sampling because removing obvious defects is faster than applying a sampling table.

Major defects include wrong design, wrong finished size beyond tolerance, incorrect backing, missing hook or loop, loose border longer than 5 mm, adhesive on the face, severe color mismatch on a critical brand color, stains visible at 50 cm under normal daylight and text that is unreadable compared with the approved sample. Minor defects include isolated yarn floats under 3 mm, slight edge fuzz, trimming tails under 2 mm and minor variation in non-critical colors.

If patches will be applied to garments, include a wash check. A reasonable factory-side test is 3 domestic wash cycles at 40°C followed by air drying, checking for delamination, border unraveling, color bleed and face distortion. For workwear, uniforms or outdoor apparel, the final garment supplier should test the patch on the actual fabric because adhesion depends on coating, pressure, temperature and dwell time.

Inspection item	Suggested specification	Reject condition
Finished size	±1.0 mm under 80 mm; ±1.5 mm from 80 to 150 mm	Outside tolerance, bowed or visibly distorted
Color match	Approved yarn card or approved sample controls bulk	Critical brand color clearly off under normal light
Border	Continuous, no loose thread over 5 mm	Unraveling, skipped overlock, burnt or melted edge
Backing adhesion	Even film or hook coverage; no face contamination	Peeling before application, missing backing, glue on front
Text legibility	Matches approved physical sample at 30 cm viewing distance	Letters closed, broken or unreadable
Packing count	Per PO, SKU and carton label	Short count, mixed designs without approved separation

8. Packing, Carton Labeling and RFQ Checklist

Packing should protect edges, keep SKUs separated and make inbound counting simple. Standard bulk packing is 50 or 100 pcs per inner polybag, then export carton. Add desiccant for sea freight or humid storage. For retail programs, specify individual OPP bag size, backing card material, hang hole, barcode label position and whether hook-backed patches require loop protectors so they do not catch other products.

Typical export cartons for woven patches are 40 x 30 x 30 cm or 45 x 35 x 30 cm. Keep gross weight under 12 to 15 kg to reduce crushing and carton splitting during courier handling. Carton labels should show PO number, design name, SKU, quantity, carton number, gross weight, net weight and country of origin if required. Mixed cartons should only be used with an approved carton map; otherwise separate each design by inner bag and carton.

Before requesting a quote, send one controlled spec sheet with finished size, cut outline, yarn colors, border, backing, quantity tiers, packing method, inspection level and target ship date. Attach vector artwork and a PNG preview. Mark which colors, dimensions and text are critical. If the artwork may work better as embroidered, PVC or printed fabric, ask for two build options before sampling.

• Confirm finished size in millimeters, including border and backing assumptions.
• Provide vector artwork, cut line and PNG preview.
• State Pantone references and mark critical colors for physical approval.
• Choose merrowed, laser-cut, heat-cut, stitched outline or borderless edge.
• Specify backing: none, hot-melt iron-on, sew-on, hook, loop or pressure-sensitive adhesive.
• Request MOQ, FOB price tiers, sample lead time and bulk lead time by design.
• Define size tolerance, AQL level and major/minor defect rules before production.
• Approve a physical sample before bulk production for any brand logo or retail item.
• Lock inner packing, carton labels and mixed-SKU rules before shipment.
