Custom special interlining is engineered beyond standard woven or non-woven bases to hit a defined performance target — enzyme-washed hand, flame resistance, stretch recovery, or a bonding profile matched to a difficult face fabric.
Special interlining is any interlining construction engineered past a standard woven or non-woven base to deliver a specific functional or aesthetic result — a softer enzyme-washed handfeel, added elastic recovery, water repellency, flame resistance, antibacterial finishing, or a bonding profile tuned to a face fabric that standard interlining can't fuse cleanly to. Rather than picking from a catalog, a garment brand defines the performance goal and the interlining is built around it.
The building blocks are the same four variables in every case: base fiber and construction, resin and coating chemistry, dot pattern and add-on weight, and finishing treatment. Adjusting any one of these changes drape, stiffness, wash behavior, and bond strength — which is why custom special interlining is best treated as an engineering project with a defined spec, not a single product selection.
Jiaxing Rainbow (UBL) Interlining Co., Ltd. produces enzyme-washed, recycled-fiber, and other treated or coated constructions on the same production lines featured on its Special Interlining product page, alongside standard woven and non-woven bases that can also be customized.
A custom special interlining program covers every stage of the material, giving brands and garment factories control over the finished roll from base construction through packaging.
| Variable | Options | Effect on Finished Interlining |
|---|---|---|
| Base Construction | Woven (plain, twill, warp-knit), non-woven (nylon, polyester, blended web), hair canvas, felt | Determines base drape, stretch, and dimensional stability |
| Coating & Dot Pattern | PA, PES, PE, EVA, double-dot resin systems | Sets bond strength, hand feel, and fusing press compatibility |
| Functional Finishing | Enzyme wash, flame retardant, water repellent, antibacterial, stretch/recovery, recycled fiber | Adds a specific performance property beyond structural support |
| Weight, Width & Color | GSM, roll width, dye/color matching | Matches interlining to tech pack and face fabric weight |
| Packaging & Labeling | Private-label rolls, custom carton marking, documentation | Supports OEM clients shipping under their own brand |
Fusing bond strength depends on three press variables — temperature, pressure, and dwell time — plus the resin system used. Adjust the settings below to see how the fuse cycle affects estimated bond strength, then press Fuse to run the cycle.
The reference minimum of 10 N/5cm (200 cN/cm) is a commonly cited industry benchmark for acceptable fused-bond strength; actual pass/fail criteria should be set per your own tech pack and verified using ASTM D2724 — see Sources below.
| Application | Interlining Role | Product Page |
|---|---|---|
| Overcoats | Structural support for collars, lapels, and chest pieces under heavy fabric weight | Overcoat Interlinings → |
| Suits & Blazers | Precise handfeel and drape control for tailored garments | Suit Interlinings → |
| Skirts & Formalwear | Lightweight body and volume for structured petticoats and dresses | Petticoat Interlinings → |
| Trench Coats & Outerwear | Weather-resistant, shape-retaining support layer | Trench Coat Interlinings → |
Beyond apparel, the same custom construction principles extend to shirts, uniforms, bags, and select technical, automotive, and home-textile projects requiring shape retention or a specific functional finish.
As a vertically integrated manufacturer, Jiaxing Rainbow (UBL) Interlining operates its own weaving, non-woven, coating, and finishing lines rather than outsourcing production, which keeps quality and lead time under direct control.

In-house double-dot coating lines, dyeing, and enzyme-wash finishing equipment support both small sampling runs and bulk-order scale. See the Production Process and Delivery Services sections of the Advantage page, or browse the full Product range for standard bases available for customization.
| Step | What Happens |
|---|---|
| 1. Requirement Consultation | Share a tech pack, target fabric, and performance needs via Get In Touch |
| 2. Formulation & Sampling | Base construction, resin system, and finishing are selected; lab and pilot samples are produced for approval |
| 3. Fusing & Performance Testing | Bond strength, shrinkage, drape, and wash durability tested against the actual face fabric |
| 4. Bulk Production | Approved specifications move to in-house production lines with quality checkpoints at every stage |
| 5. Packaging & Shipment | Custom packaging, labeling, and logistics coordinated through Delivery Services |
Every batch passes through incoming raw material inspection, in-process bonding and shrinkage checks, and a final pre-shipment audit. The core tests that apply to fused interlining are internationally standardized rather than proprietary:
Colorfastness, dimensional stability, and washing durability are checked against these references before goods leave the facility. Full detail on inspection stages is available on the Quality Assurance section of the Advantage page.
MOQs vary by construction and finishing type. Development samples can typically be produced in small quantities, with bulk pricing tiers available for production orders.
Yes. Sending a physical swatch or technical specification allows the team to replicate handfeel, weight, and bonding performance, adjusting resin and base construction as needed.
Yes — custom formulation, packaging, and labeling are available so finished rolls can ship under your own brand.
Beyond fashion and tailoring, these interlinings are used in bags, home textiles, and select industrial applications requiring shape retention or functional performance. More answers are on the main FAQ page.
