Interlining & Fuse-Tape Specs for Private-Label Suits
EU private-label teams often write excellent lapel widths — then leave interlining and fuse tape as “factory standard.” At Shi Yuan Suit Factory, that phrase is not a spec. This informational post lists the fields buyers should write so fused and taped zones stay consistent from sample to bulk from 50.
Commercial anchors: MTM from 1 when you develop on a client; sample 7–14 days after measurements and fabric are confirmed; production 14–21 days after written confirmation. Factory: Baodi, Tianjin · Chengxingwang · Est. 2009. Acumenwear = export domain only.

Why interlining specs belong in the PL brief
Interlining and fuse tape affect:
Chest clean vs boardy hand
Pocket mouth stability
Hem and vent behavior after press
How the garment ages through steam cycles

Spec fields table (write these — do not invent supplier brand names)
We do not invent tape-supplier brand names on a blog. Write performance fields; we confirm materials we actually use on your sample sheet.
Construction path — What buyer should write: Fused / half / full — Example phrasing (not a brand): “Half canvas chest; fused elsewhere as agreed”
Fuse zones — What buyer should write: Where fuse is allowed / banned — Example phrasing (not a brand): “No fuse on lapel roll line” / “pocket mouth fused”
Hand feel target — What buyer should write: Soft / medium / firm — Example phrasing (not a brand): “Medium chest, soft skirt”
Cloth pairing — What buyer should write: Mill code + weight class — Example phrasing (not a brand): “Tropical wool ~220–250g — confirm fuse weight”
Tape at roll / edge — What buyer should write: Yes/no + location — Example phrasing (not a brand): “Stay tape at pocket; shoulder seam tape as standard”
Hem / vent support — What buyer should write: Interlining yes/no — Example phrasing (not a brand): “Vent stay as sample”
Press / steam assumption — What buyer should write: Retail press heavy or light — Example phrasing (not a brand): “Boutique light steam only”
Sample lock — What buyer should write: Must match bulk — Example phrasing (not a brand): “Bulk fuse path = sealed sample path”
Change control — What buyer should write: Who can alter fuse path — Example phrasing (not a brand): “Only seal owner on WhatsApp”
QC photo ask — What buyer should write: Optional — Example phrasing (not a brand): “Chest open photo on 1st size during bulk”

How EU buyers should shortlist factories on this topic
Ask:
Will the sample sheet list fuse zones?
Can we refuse a bulk change to a heavier fuse without a new seal?
Can we get a chest-open photo on the first bulk size?
Avoid “Italy canvas” adjectives without zone maps. Capability: private label · process.
Sample → bulk discipline
Seal the fuse path with the silhouette sample.
Do not “upgrade” fuse weight mid-bulk to chase a firmer photo without written change + possible re-sample.
Shade and fuse are separate — fabric lot shade.
Mid-spec CTA:
Tie-in to other PL specs

Common EU PL questions
Can you copy a competitor’s fuse without a sample? We need your sealed sample or a clear zone map — not a guess from a store photo.
Do you publish tape brand SKUs on the website? No. Materials are confirmed per order on the sample sheet.
Is half canvas “no fuse”? No. Half canvas still uses fuse/tape in defined zones; the chest path differs. Name both.
Example: how a Berlin PL team filled the table
Construction path: half canvas chest; fused skirt and pocket mouths
Fuse zones banned: lapel roll line kept soft per sample
Hand feel: medium chest, soft skirt
Cloth: mill code on file, ~240g tropical
Tape: pocket mouth + shoulder as sample; no extra chest tape beyond half-canvas path
Hem/vent: vent stay as sample
Press assumption: boutique light steam
Sample lock: bulk = sealed path
Change control: brand tech designer only
QC photo: chest-open on first 42R during bulk
That one page cut two rounds of “why does bulk feel firmer?” arguments.
Tie fuse specs to margin conversations
Firmer fuse is not free margin. It changes hand feel and can raise remake risk if it diverges from the seal. Price conversations belong in written quotes after construction is named — not as invented retail tags on a blog. Keep fuse path stable when you are optimizing door margin via cloth choice and silhouette instead.
Sample photo asks that protect fuse specs
On the sealed sample, request:
Chest open (shows canvas / fuse path)
Lapel roll close-up
Pocket mouth after press
Hem / vent after press
Store these with the tech pack. Bulk disputes then compare against photos, not memory. Pair with tech pack photo brief.
Bottom line
Interlining and tape are spec fields, not vibes. Fill the table, seal on sample, then bulk from 50 stays consistent. Shi Yuan · +65 8013 8838 · houzhenying226@gmail.com
