Polyester light weight nonelastic down jackets are popular choices among outdoor enthusiasts

Non-fusible non-woven interlining is a type of fabric that is commonly used in garment construction to provide shape, support, and stability to the garment. It is made by bonding synthetic fibers together without the use of heat, making it non-fusible. This type of interlining is preferred over fusible interlining for down jackets as fusible interlining can melt and lose its shape when exposed to high heat, which can be a problem during the manufacturing process.

The non-elasticity of the interlining is also important for down jackets, as the down insulation requires a certain amount of looseness and space to provide maximum insulation. Elastic interlining, on the other hand, would cause the jacket to pull and stretch, which would reduce the effectiveness of the insulation.

In addition, the non-woven nature of the interlining makes it lightweight and breathable, allowing the jacket to retain its insulating properties without adding unnecessary bulk or weight. This is especially important for down jackets, as they are designed to be lightweight and packable, making them easy to transport and wear in a variety of weather conditions.

Overall, a high-quality non-fusible non-woven interlining is essential for the construction of a polyester lightweight nonelastic down jacket.  Polyester Light Weight Nonelastic Down Jacket Garment Non Fusible Non Woven Interlining provides the necessary shape, support, and insulation while remaining lightweight and breathable, making it the perfect choice for outdoor enthusiasts looking for a high-performance garment that can keep them warm and comfortable in any weather conditions.
