Our tip: The ideal interlining depends on the fabric, garment application, processing requirements, and desired performance characteristics.

Yes. We provide interlining samples and technical recommendations based on your fabric, garment construction, manufacturing process, and performance requirements.

Woven interlinings

• Excellent stability
• Structured appearance
• Premium garment presentation

Nonwoven interlinings

• Versatile applications
• Flexible constructions
• Efficient processing

Our tip: Woven interlinings are often preferred for shirts and tailoring applications.

Knitted interlinings are designed for stretch fabrics and applications requiring flexibility, recovery, and wearer comfort. They help maintain garment performance while preserving fabric elasticity.

Our tip: Match the stretch characteristics and direction of the interlining to those of the garment fabric.

Wendler's WSF, WSC, SE, and VEM Lines are commonly used for shaping, structure, and reinforcement in suits, jackets, and tailored garments.

Our tip: The desired silhouette, level of structure, and garment construction determine the most suitable tailoring solution. Our technical team can help identify the optimal combination for your application.

Yes. Wendler's KW and RS Lines provide flexibility, recovery, and stretch compatibility for knitwear, sportswear, activewear, and other stretch garments.

Our tip: Select interlinings that support the fabric while maintaining comfort, flexibility, and freedom of movement. We recommend validating stretch performance under actual production conditions.

Wendler's DV WP, PC / IL, and D Lines are designed for demanding workwear and uniform applications requiring durability, heat resistance, and industrial laundry performance.

Our tip: Consider processing conditions, industrial washing requirements, and end-use performance during product selection. Our specialists can support you in selecting the most suitable solution.

The ideal shirt interlining depends on the fabric, collar construction, desired appearance, and processing requirements. Popular solutions include Wendler's DV, 3000, 3600, DUETT, 7000, and HF Lines.

Our tip: Collar, collar band, and cuff constructions should be selected as a balanced system to achieve the desired appearance, comfort, and performance. Our specialists can help identify the best combination for your fabric and manufacturing process.

A collar can collapse if the collar band interlining is too light and thus not stable enough to hold the weight of the top collar with its basic and patch interlinings. An incorrect collar pattern can also cause instability.

Our tip: Contact us for support. We will help you find the right interlining combination for a stable, well-shaped collar.

Successful fusing depends on three key parameters:

• Temperature
• Pressure
• Time

Our tip: Optimal balance—not maximum settings—delivers the best results. Wendler's technical specialists can support parameter optimization for specific fabric and interlining combinations.

Every fabric and interlining combination behaves differently during processing. Testing helps verify bonding performance, optimize machine settings, and reduce production risks.

Our tip: Testing is one of the most effective quality-control measures. Wendler recommends validating all new fabric and interlining combinations before bulk production.

Steam should generally not be used during the fusing process because it can negatively affect adhesive bonding performance.

Our tip: A controlled dry process provides more consistent and reliable results.

As a general rule, fused parts should be placed across the conveyor belt. They can also be positioned diagonally if needed.

Our tip: Place fused parts in an offset position and use the full belt width for more consistent fusing results.

Interlining strike through can occur when the fusing parameters such as temperature, time, or pressure are not correctly adjusted. It may also happen when the shirt fabric is very transparent or has an open weave construction, allowing the adhesive to become visible on the fabric surface.

Our tip: Always carry out fusing tests before bulk production and adjust the fusing parameters as needed to achieve the best result.

Interlining strike back can occur when the fusing temperature, time, or pressure is too high, especially in the first heating zone. This may cause the adhesive to migrate back into the interlining.

Other possible causes:

• Excessive fusing pressure
• Adhesive sinking back into the interlining construction
• Difficult-to-fuse shirt fabrics
• A dirty conveyor belt

Our tip: Test and optimize your fusing parameters before bulk production. Correct machine settings help prevent strike back and ensure reliable bonding.

A yellowish discoloration can occur when the fabric is overfused due to excessive temperature or fusing time. In some cases, the discoloration disappears after the fused part has cooled.

Our tip: Carry out fusing tests before bulk production and adjust the fusing parameters if necessary. This helps prevent discoloration and ensures consistent results.

Interlining can detach or form bubbles after washing if the bond between the fabric and interlining is not strong enough. This can happen when fused parts are handled while still hot or when the fusing process is not optimal.

Common causes:

• Fused parts are processed before cooling completely
• Threads or fluff between fabric and interlining
• Damaged coating dots
• Incorrect fusing parameters
• Low bonding strength
• Improper fusing on the conveyor belt

Our tip: Let fused parts cool completely before further processing and test fusing parameters before bulk production to ensure a strong, durable bond.

• Incorrect fusing parameters
• Contamination between layers
• Insufficient cooling time
• Unsuitable interlining selection

Our tip: Allow fused components to cool completely before further processing. Selecting the right interlining and fusing parameters from the start helps prevent washing-related failures.

The moiré effect can appear when the weave of a shirt fabric interacts with the construction of the interlining. This creates visible wavy or shadow-like patterns on the fabric surface.

Our Tip: To help prevent the moiré effect:

• Cut the interlining slightly on the diagonal, not in the warp direction.
• Choose an interlining with a different construction or weave.

These simple adjustments can reduce pattern interference and improve the final appearance of the garment.

A collar can collapse if the collar band interlining is too light and thus not stable enough to hold the weight of the top collar with its basic and patch interlinings. An incorrect collar pattern can also cause instability.

Our tip: Contact us for support. We will help you find the right interlining combination for a stable, well-shaped collar.

All Wendler interlinings in black and charcoal colour have a modified coating (MC coating). This prevents strike-through.

Our tip: You can also prevent strike-through by using coloured coating dots (CP finishing). This is particularly good for very transparent fabrics. The coloured coating dots are not visible on the fabric surface.

Glue residue is usually caused by:

• Conveyor contamination
• Adhesive build-up
• Incorrect cutting dimensions

Our tip: Regular machine cleaning and preventive maintenance help avoid contamination.
