Interlining is the hidden layer that gives a collar its crispness, a jacket front its shape and a waistband its stability. Among the available types, woven interlining is still the benchmark for garments that need dimensional stability, a controlled handle and long-term shape retention.
What Is Woven Interlining?
Woven interlining is a supporting textile made by interlacing warp and weft yarns on a loom, then finishing it and, in most cases, coating one face with a heat-activated adhesive. Because the yarns interlace in a defined pattern, a woven base has predictable grain direction and a lower tendency to distort than a randomly bonded nonwoven. That is why tailoring, shirting and structured outerwear still rely on it heavily.
Woven bases are generally made from cotton, polyester, or blends. The yarn count, weave density and finishing process set the weight, stiffness and recovery of the interlining. Coating is applied afterward, and it governs how the interlining bonds to the face fabric.
Fusible vs. Non-Fusible Woven Interlining
Fusible woven interlining carries an adhesive coating, such as polyamide (PA) or polyester-based resin, applied in a dot pattern. Heat, pressure and time melt the resin so it bonds to the fabric. This is the standard choice for high-volume garment production because it is fast and consistent.
Non-fusible woven interlining has no adhesive. It is sewn in, which suits traditional tailoring, heat-sensitive fabrics, or garments where the maker wants the layers to move independently. It takes more labor but allows a softer, more natural drape.
Woven Interlining Product Lines at a Glance
UBL's wholesale woven interlining range covers four construction types. The table below summarizes them, based on the information published on our product page.
| Product line | Construction | Key characteristics | Typical applications |
|---|---|---|---|
| PA Double-Dot Woven Fusible (14–125 gsm) | Woven base, double-dot coating | Very wide weight range; strong, even adhesion; keeps drape and breathability | Blouses, shirting, and heavier structured garments |
| Twill Woven Fusible, Series 7 | Twill weave base | Added strength, smooth tailored finish, good shape retention | Suiting, outerwear, structured components |
| Tricot Series 4 | Tricot-based | Stretch recovery, soft handle | Fashion apparel, lighter constructions |
| Knitting Series 1 | Knitted construction | High elasticity and drape without losing support | Knitwear and stretch fabrics |
You can view product details for Twill Woven Fusible Interlining – Series 7 and Tricot Series 4 on their own pages. For the wider catalog, see our Woven Interlining and Non-woven Interlining categories.
Technical Factors That Decide Performance
1. Weave or knit structure
A plain weave gives a balanced, firm handle. A twill weave is denser and more flexible along the diagonal, which is why it suits tailored and outerwear pieces. Warp-knit constructions such as tricot trade some rigidity for stretch and recovery. Match the structure to how the garment must move, not only to how stiff it must feel.
2. Weight (gsm)
A general rule is to choose an interlining slightly lighter than, or equal to, the face fabric so the garment keeps its natural fall. The 14–125 gsm span of our double-dot line lets one coating technology serve both sheer blouses and structured pieces.
3. Coating type and dot pattern
Coating is applied as discrete dots so the fabric stays breathable and flexible. A double-dot layout uses a small base dot plus a top dot, which helps the resin bond on the surface instead of sinking into the fabric, one of the common causes of weak adhesion and strike-through. Resin type matters too. Polyamide is commonly used where dry-cleaning or washing performance is required, while other resins suit different fabrics and care labels. Always confirm resin type against the care instructions your brand will print on the garment.
4. Dimensional stability
If the interlining shrinks differently from the face fabric, you get puckering, bubbling or a twisted seam after laundering. Dimensional change is normally tested to ISO 5077, which covers washing and drying of fabrics and garments (ISO 5077:2007 listing, DIN Media). In practice the washing and drying cycles come from ISO 6330 for domestic laundering, and specimens are marked and measured under ISO 3759, as described by the testing institute RISE. Testing the fused composite, not the two layers separately, gives the most reliable picture.
How to Choose the Right Woven Interlining
| Face fabric / garment | Priority | Direction to consider |
|---|---|---|
| Light shirting, blouses | Soft handle, no strike-through | Low-gsm PA double-dot woven |
| Suits, jackets, coats | Body, shape retention | Twill woven fusible (Series 7); see our suit and overcoat solutions |
| Trench coats | Structure with comfort | Twill or medium double-dot; see trench coat interlinings |
| Fashion apparel with some stretch | Recovery, soft feel | Tricot Series 4 |
| Knitwear, stretch fabrics | Elasticity, drape | Knitting Series 1 |
The table is a starting point. The most reliable approach is to test your actual fabric with two or three candidate interlinings, then evaluate bond strength, handle and appearance after washing or dry cleaning.
Fusing: Where Most Problems Start
Even a well-made interlining fails if it is fused incorrectly. Three variables work together: temperature, pressure and time. Supplier data sheets give the working window, and typical garment fusing sits in the range of roughly 110–150 °C, around 10–15 seconds, with moderate, even pressure. Treat these as general orientation only. Heat-sensitive fabrics such as some synthetics and silks need lower temperatures and longer dwell times, so always follow the data sheet for the specific product and run a trial.
| Symptom | Likely cause | What to check |
|---|---|---|
| Bubbling or delamination after wash | Insufficient bond; resin not fully activated | Press temperature at the fabric surface, dwell time, pressure uniformity |
| Resin visible on the face (strike-through) | Excess heat or pressure; open face weave | Lower temperature, a finer dot, or a different coating |
| Puckering or rippling | Shrinkage mismatch between layers | Pre-shrink face fabric; compare dimensional change results |
| Stiff, board-like handle | Interlining too heavy or too dense for the fabric | Drop one weight class or switch to a more flexible construction |
Customization and Wholesale Supply
Off-the-shelf rolls do not always fit a specific fabric and process. UBL offers each woven line with adjustable width, weight, color and coating type, supported by in-house R&D, testing, and flexible minimum order quantities for wholesale and OEM orders. Our production process and quality assurance pages describe how we control batches from yarn selection through coating and finishing, and delivery services covers shipment planning. To learn more about the manufacturer, visit the company page.
Buyer's Checklist Before Placing a Bulk Order
- Request a technical data sheet and confirm the fusing window for your press type.
- Order samples and test them on your real production fabric, including after wash or dry-clean cycles that match the care label.
- Check grain direction and cutting orientation so the interlining and face fabric align.
- Ask for batch-to-batch consistency information and lead time before committing to volume.
- If your market has chemical-safety requirements, ask the supplier for current documentation rather than assuming compliance.
Frequently Asked Questions
Is woven interlining better than nonwoven?
Neither is universally better. Woven suits garments that need stability, defined grain and durability, such as tailoring. Nonwoven is often chosen for cost efficiency and uniform support. The FAQ page covers more common questions.
Can woven interlining be used on stretch fabrics?
Standard rigid weaves limit stretch, so stretch garments generally use tricot or knitted constructions that move with the fabric.
Can I request a custom specification?
Yes. Width, weight, color and coating type can be tailored for wholesale and OEM projects.
