The Multi-Layer Sandwich Structure of Spacer Knit Fabric

As a specialized air layer fabric, the D456 brushed spacer fabric for trench coat utilizes a multi-layer knit construction. This double-knit or sandwich structure consists of a top face, a bottom backing, and a micro-space connection layer. By trapping still air within this internal pocket, the fabric acts as a natural thermal barrier, offering windproof performance and heat retention without adding heavy physical weight. For apparel designers, this means the 340 gsm polyester spandex spacer fabric provides the substantial, sculptural volume required for high-end outerwear while remaining breathable and comfortable for the wearer.

Faux Suede Texture Combined with Advanced Fiber Performance

The face of Item Code D456 undergoes a precise brushing process to create a washed matte-napped finish. This treatment gives the spacer knit fabric a luxurious tactile quality resembling velvet or fine nubuck leather, while the reverse side remains a smooth backing for comfortable wear.
This aesthetic appeal is backed by the intrinsic properties of its fiber composition (96% Polyester / 4% Spandex):
- Polyester (96%): Provides exceptional dimensional stability and quick-drying performance, ensuring outerwear garments retain their shape after repeated wear and wash cycles.
- Spandex (4%): Delivers high stretch with strong elastic recovery, allowing structured garments like trench coats and jackets to move comfortably with the body without bagging or losing their crisp lines.
This combination ensures the fabric is highly wrinkle-resistant, breathable, and pill-resistant, making it a reliable choice for premium fashion brands looking for a trusted spacer fabric supplier.
