Nonwoven interlining is often used to stabilize garment shape and ensure consistent sewing quality. However, rather than simply choosing a thick or thin product, you should review weight, thickness, hand feel, bonding conditions, and application area.
Weight and thickness are not the same standard
Weight refers to the weight per unit area, and thickness affects the actual volume and hand feel. Even if the weight is the same, it may feel softer or firmer depending on the fiber composition and processing method.
Selection criteria by application area
Areas that require shape stability, such as the collar, front hem, sleeves, and waist, may lose shape if interlining is too weak. Conversely, an overly hard interlining on a thin, soft fabric can ruin the feel of the shell fabric.
Harmony with fabric
If the shell fabric is thin or transparent, the interlining color and surface texture are also important. If the fabric shrinkage rate and interlining shrinkage rate do not match, tearing or warping may occur after washing, so it must be checked after sample bonding.
Pre-production test points
Appearance, hand feel, bending after bonding, change after washing, sewability, and cutting stability must be examined together. It is safe to test under actual working conditions, especially before mass production.
Information Needed for Consultation
It's easy to narrow down suitable nonwoven interlining candidates by telling us your garment type, application area, shell fabric fabric composition, desired hand feel, washing conditions, and monthly usage.
Frequently Asked Questions
Is sample testing necessary?
Because results can vary depending on the fabric, sewing conditions and washing requirements, sample testing before mass production is recommended.
Can you match the feel of an existing material?
If possible, please share an existing material sample, photos, weight, width and composition information. This helps us review similar options more quickly.

Why Weight and Thickness Should Be Reviewed Together
A heavier nonwoven interlining is not automatically stronger or better. Even at the same weight, hand feel and shape retention can vary depending on fabric structure, adhesive resin and finishing method. For thin outer fabrics, check surface bubbling and show-through; for thick outer fabrics, check whether reinforcement is sufficient.
Test Points by Application
- For shirt collars and cuffs, check shape retention and peeling after washing.
- For jacket fronts, check the balance between silhouette support and natural hand feel.
- For thin fabrics, check interlining color, show-through and surface change.
- For uniforms, prioritize shrinkage and bonding stability after repeated washing.
Information Needed for Consultation
If you share the outer fabric type, application area, desired stiffness, washing method and existing interlining sample, the suitable weight and thickness range can be narrowed down more quickly.
