Interlining FAQs

Common Technical Questions About Interlinings

Interlinings are made using different base fabrics depending on the application and performance requirement. The most commonly used base fabrics include:

  • Non-woven fabric
  • Circular knitted fabric
  • Warp knit fabric
  • Warp knit weft insert
  • Woven fabric

Each type is selected based on the required strength, softness, stretch, and dimensional stability of the final garment.

Generally, shrinkage should not exceed 2%. For high-quality tailoring and formal wear, shrinkage should ideally remain within 1%.
Low shrinkage is critical to prevent garment distortion, bubbling, or shape loss after washing or dry cleaning.

No. Interlinings can be either fusible (heat-bonded) or non-fusible (sew-in).
Fusible interlinings are widely used today due to efficiency and consistency, while sew-in interlinings are still preferred for delicate, coated, or heat-sensitive fabrics.

Fusible interlinings use hot-melt adhesives such as polyethylene, polyamide, polyester, and EVA.
When bonded correctly under recommended fusing conditions, these adhesives are safe for garment use and compliant with industry standards.

Different fabrics require different bonding behaviour:

  • Lightweight fabrics need smaller dots to avoid stiffness and strike-through
  • Heavier fabrics need larger dots for stronger adhesion

Dot size directly affects bonding strength, softness, breathability, and overall garment feel.

Yes. Fabric finishes such as water-repellent, silicone, resin, PU coatings, or heavy softeners can reduce or block adhesion.
This is why interlinings should always be tested on the actual finished fabric before bulk production.

Interlining bonding is evaluated through:

  • Peel strength testing
  • Wash durability testing
  • Dry-clean durability testing
  • Visual inspection and hand-feel assessment

These tests ensure the interlining remains bonded and maintains appearance over time.

Interlinings control structure, drape, and shape retention.
They determine whether a garment appears soft and flowing or crisp and structured, especially in collars, lapels, plackets, cuffs, and waistbands.

No. Different garments require different interlinings based on

  • Fabric weight and type
  • Stretch or non-stretch requirement
  • Desired softness or firmness
  • End use (formal, casual, performance)

There is no universal interlining solution.

Key factors include:

  • Fabric type and weight
  • Garment type and end use
  • Desired fall and hand-feel
  • Washing or dry-cleaning requirements
  • Fabric finishes
  • Cost and production scale

Testing before bulk production is always recommended.

Bubbling or delamination is one of the most common garment defects and is usually caused by:

  • Incorrect temperature, pressure, or dwell time
  • Incompatible fabric finish
  • Incorrect adhesive selectionl
  • Moisture in the fabric
  • Poor cooling after fusing

This issue is almost always related to process or compatibility, not just material quality.

  • Strike-through occurs when adhesive becomes visible on the fabric surface
  • Strike-back occurs when adhesive bleeds onto the fusing machine belt

Both are caused by excess heat, pressure, or incorrect interlining selection.

Even the best interlining will fail if the fusing machine has:

  • Incorrect temperature
  • Uneven pressure
  • Wrong dwell time
  • Poor cooling or maintenance

Machine settings are as critical as interlining quality.

Even the best interlining will fail if the fusing machine has:

  • Check temperature uniformity
  • Check pressure consistency
  • Verify dwell time
  • Ensure proper cooling
  • Fuse a test sample and check peel strength and appearance

Daily checks help prevent large-scale defects.

The Moiré effect is a visual wave or ripple pattern that appears when the interlining dot pattern interferes with the fabric weave.
It is an optical issue and can be controlled by selecting the correct dot pattern and interlining structure.
