Selection of interlining and setting of press conditions to prevent deformation after sewing

Understanding Interlining in Garment Design

Interlining plays a crucial role in garment construction, providing stability and structure to fabrics that will be sewn into clothing items.
It acts as an additional layer between the outer fabric and the lining, ensuring that garments retain their shape and resist deformation over time.

In fashion design, choosing the correct interlining and setting appropriate press conditions are essential steps to achieve high-quality finishes.
This article will explore the varieties of interlining, their applications in different fabrics, and the considerations for pressing conditions to ensure optimal results.

Types of Interlining

Interlining can be classified based on its material, structure, and application.
The three main types of interlining materials are woven, knitted, and non-woven.

Woven interlinings are made from yarns woven together, offering a firm structure.
They are ideal for use with tailored garments like suits and jackets due to their ability to maintain shape and add crispness.

Knitted interlinings provide a more flexible and elastic quality, making them suitable for stretch fabrics.
These are often used in knitwear and sportswear to allow garments to move comfortably with the body.

Non-woven interlinings are produced from fibers bonded together, which makes them lightweight and easy to apply.
They are versatile and used across various garments, providing both stability and additional support where needed.

Choosing the Right Interlining

When selecting interlining, consider the outer fabric’s weight, composition, and intended garment use.
Heavy fabrics such as wool or denim typically require a robust interlining to sustain the garment’s weight, while lighter fabrics like silk might need a soft interlining to maintain their delicate nature.

Compatibility with the outer fabric is vital.
For example, a woven interlining suits tightly woven outer fabrics, while a knitted interlining is better for stretchable materials.

Also, consider the finish you desire in the garment.
Some interlinings enhance the drape of a fabric, while others emphasize structure and shape.
The transparency of the outer fabric is another factor, as a visible interlining can affect the garment’s aesthetic.

Pressing Conditions for Optimal Results

Proper pressing conditions are essential for setting the interlining into the garment without causing fabric deformation.
This process ensures that the layers of fabric are appropriately fused, maintaining the garment’s intended look and durability.

Temperature and Pressure

The correct temperature for pressing interlining depends on its material and the outer fabric.
Typically, higher temperatures are needed for synthetic fibers, while natural fibers require lower settings.
Always refer to the manufacturer’s instructions and test on a scrap piece before application.

Pressure also plays a critical role.
Too much pressure can lead to imprints on delicate fabrics, while too little will not secure the interlining effectively.
Adjusting pressure based on the fabric and interlining thickness ensures a smooth fusion.

Pressing Time

The duration for applying heat to the interlining must be balanced—sufficient to secure the bond but not so long that it causes shrinkage or damage.
Short bursts of pressing with time to cool in between can help prevent overstretching and distortion.

Moisture and Steam

Moisture can aid in the bonding process, especially with certain fusible interlinings.
However, excessive steam can cause shrinking or bubbling in some materials.
It is crucial to test the fabric for steam sensitivity and adjust the steam setting accordingly.

Strategically applying moisture through a damp pressing cloth can help achieve the desired bonds without direct moisture exposure to the fabric.

Preventing Deformation Post-Sewing

After sewing, garments can experience deformation due to stresses from movement or washing.
Proper interlining and pressing conditions help prevent this, but additional measures can further enhance garment stability.

Reinforcing Stress Points

Reinforcing areas prone to strain, like seams and buttonholes, with stay tapes or additional interfacing can reduce deformation risk.
This reinforcement provides extra support, maintaining the garment’s shape through wear.

Handling and Maintenance

Finally, handling and maintaining garments properly contribute to their longevity.
Care instructions should consider the interlining used, advising on laundering methods—such as dry cleaning or gentle handwashing—that minimize stress on the bonded layers.

Consistent maintenance through gentle pressing and correct storage prevents unnecessary strain on the garments, preserving their intended look and structure over time.

In conclusion, careful selection of interlining and attentive setting of pressing conditions form the foundation for durable and high-quality garment construction.
By understanding and applying these principles, designers and manufacturers can produce clothing that stands the test of time, retaining its beauty and shape.
