kuidunkalvoissa

kuidunkalvoissa is a Finnish technical term that refers to synthetic fabrics engineered to mimic the appearance and mechanical behavior of quilted textiles. In these materials, a core of flexible polymer or foam is encapsulated between two or more outer layers of woven or knitted textile. The outer skins are typically made from nylon or polyester blends, while the core may consist of polyurethane foam, polyethylene, or a lightweight polymeric foam. The quilting effect is achieved by stitching or thermally bonding the skins to the core, establishing a series of raised joints that provide a textured surface.

The concept was developed in the 1990s by Finnish researchers collaborating with textile manufacturers, with the aim of creating lightweight, padded clothing and protective gear. The quilting arrangement distributes impact forces across a wider area, improving shock absorption and enhancing thermal insulation. Because the fabrics retain the flexibility of the outer skins while offering a structured core, they find applications in performance apparel, sports equipment, and ergonomic accessories. In industrial settings, kuidunkalvoissa fabrics are used for insulating panels, vibration damping in machinery, and as soft‑edge protective liners in automotive interior panels.

The term has become part of the product catalogue of several European textile companies. Kits for building quilted core composites are available for researchers and hobbyists, and the technology is included in a number of patents concerning layered cushioning systems.
